Query: Antidepressants reduce the severity of migraines.
OBJECTIVE To evaluate the efficacy and relative adverse effects of tricyclic antidepressants in the treatment of migraine, tension-type, and mixed headaches. DESIGN Meta-analysis. DATA SOURCES Medline, Embase, the Cochrane Trials Registry, and PsycLIT. Studies reviewed Randomised trials of adults receiving tricyclics as only treatment for a minimum of four weeks. DATA EXTRACTION Frequency of headaches (number of headache attacks for migraine and number of days with headache for tension-type headaches), intensity of headache, and headache index. RESULTS 37 studies met the inclusion criteria. Tricyclics significantly reduced the number of days with tension-type headache and number of headache attacks from migraine than placebo (average standardised mean difference -1.29, 95% confidence interval -2.18 to -0.39 and -0.70, -0.93 to -0.48) but not compared with selective serotonin reuptake inhibitors (-0.80, -2.63 to 0.02 and -0.20, -0.60 to 0.19). The effect of tricyclics increased with longer duration of treatment (β=-0.11, 95% confidence interval -0.63 to -0.15; P<0.0005). Tricyclics were also more likely to reduce the intensity of headaches by at least 50% than either placebo (tension-type: relative risk 1.41, 95% confidence interval 1.02 to 1.89; migraine: 1.80, 1.24 to 2.62) or selective serotonin reuptake inhibitors (1.73, 1.34 to 2.22 and 1.72, 1.15 to 2.55). Tricyclics were more likely to cause adverse effects than placebo (1.53, 95% confidence interval 1.11 to 2.12) and selective serotonin reuptake inhibitors (2.22, 1.52 to 3.32), including dry mouth (P<0.0005 for both), drowsiness (P<0.0005 for both), and weight gain (P<0.001 for both), but did not increase dropout rates (placebo: 1.22, 0.83 to 1.80, selective serotonin reuptake inhibitors: 1.16, 0.81 to 2.97). CONCLUSIONS Tricyclic antidepressants are effective in preventing migraine and tension-type headaches and are more effective than selective serotonin reuptake inhibitors, although with greater adverse effects. The effectiveness of tricyclics seems to increase over time.
We retrospectively studied the long-term (2-year) outcome of 50 consecutive patients admitted to our inpatient headache program because of chronic daily headache (CDH) associated with the overuse of analgesics, ergotamine, or both. They had been detoxified, given repetitive intravenous dihydroergotamine (IV DHE) and prophylactic medications as part of the program, and had become headache-free on this regimen. At the time of admission, 37 of the 50 patients had transformed migraine (TM), 12 had new daily persistent headache (NDPH), and 1 had chronic tension-type headache; 29 of the patients with TM, 7 of those with NDPH, and the single patient with chronic tension-type headache had coexistent migraine. Substances abused, alone or in combination, included: caffeine in 39 patients (av. 441 mg/d), acetaminophen in 32 (av. 2187 mg/d), aspirin in 24 (av. 1807 mg/d), ibuprofen in 9 (av. 1156 mg/d), narcotics in 7 (av. 10.1 mg morphine equivalents/d) and ergotamine in 11 (av. 2.3 mg/d). Twenty patients were using preventive medication at the time of admission. Follow-up evaluations were performed at 3, 6, 12, and 24 months after discharge. Forty-three patients were analyzed at 3 months. Of these, 44% had an excellent or good result and 28% a fair result; 3 were overusing analgesics. At 24 months, 39 patients were analyzed: 59% had a good or excellent result and 28% a fair result; 5 were overusing analgesics, 4 of whom were doing poorly.(ABSTRACT TRUNCATED AT 250 WORDS)
OBJECTIVE To observe the therapeutic effect of "Xingnao Kaiqiao Zhenfa" (Acupuncture Technique for Restoring Consciousness) in the treatment of post-stroke depression. METHODS A total of 256 stroke patients were divided into acupuncture group (n = 180, male 138, female 42) and medication group (n = 76, male 57 and female 19) according to their visiting sequence to our hospital. Acupoints used were Neiguan (PC 6), Renzhong (GV 26), Baihui (GV 20), Yintang (EX-HN 3) and Sanyinjiao (SP 6,the affected side) and the needles were retained for 20 min every time. Patients of medication group were asked to take Amitriptyline (50 mg/d at first, 200 mg/d). Acupuncture treatment was conducted twice daily, and after one month's treatment the therapeutic effect was evaluated. Self-Rating Depression Scale (SDS) and Hamilton Rating Scale for Depression (HRSD) were used to assess the patient's state of depression. RESULTS After the treatment, of the 180 and 76 cases in acupuncture and medication groups, 31 (17.2%) and 13 (17.1%) were cured, 73 (40.6%) and 18 (23.7%) had a marked improvement in their depression state, 27 (15.0%) and 12 (15.8%) had an improvement, 49 (27.2%) and 33 (43.4%) failed, with the effective rates being 72.8% and 56.6% respectively. The markedly effective rate and the total effective rate of acupuncture group were significantly higher than those of medication group (P < 0.05). After the treatment, the total scores of SDS and HRSD and the severity index of two groups decreased pronouncedly in comparison with those of their individual pre-treatment; and the therapeutic effects of acupuncture group were significantly better than those of medication group in reducing SDS, HRSD and severity index (P < 0 .05). In addition, the decreased values of depression, pessimistic mood and irritability of acupuncture group were all bigger than those of medication group (P < 0.05). No significant difference was found between two groups in the decreased value of insomnia (P > 0.05). CONCLUSION "Acupuncture Technique for Restoring Consciousness" can effectively improve depression patients' symptoms and the therapeutic effect of acupuncture is markedly superior to that of medication for post-stroke patients.
OBJECTIVE To investigate the frequency of depressive and anxiety disorders in patients with chronic daily headache. BACKGROUND There is a lack of data in the literature on the extent of psychiatric comorbidity in patients with different subtypes of chronic daily headache. METHODS We recruited consecutive patients with chronic daily headache seen in a headache clinic from November 1998 to December 1999. The subtypes of chronic daily headache were classified according to the criteria proposed by Silberstein et al. A psychiatrist evaluated the patients according to the structured Mini-International Neuropsychiatric Interview to assess the comorbidity of depressive and anxiety disorders. RESULTS Two hundred sixty-one patients with chronic daily headache were recruited. The mean age was 46 years, and 80% were women. Transformed migraine was diagnosed in 152 patients (58%) and chronic tension-type headache in 92 patients (35%). Seventy-eight percent of patients with transformed migraine had psychiatric comorbidity, including major depression (57%), dysthymia (11%), panic disorder (30%), and generalized anxiety disorder (8%). Sixty-four percent of patients with chronic tension-type headache had psychiatric diagnoses, including major depression (51%), dysthymia (8%), panic disorder (22%), and generalized anxiety disorder (1%). The frequency of anxiety disorders was significantly higher in patients with transformed migraine after controlling for age and sex (P =.02). Both depressive and anxiety disorders were significantly more frequent in women. CONCLUSION Psychiatric comorbidity, especially major depression and panic disorders, was highly prevalent in patients with chronic daily headache seen in a headache clinic. These results demonstrate that women and patients with transformed migraine are at higher risk of psychiatric comorbidity.
To assess the clinical and personality characteristics of patients with chronic daily headache before and after treatment, 20 patients were examined and the Minnesota Multiphasic Personality Inventory (MMPI [Italian 356-item abbreviated version]) and the Strait and Trait Anxiety Index 1,2 (STAI) administered. There were two groups: group 1 (n = 6), with a "conversion V" configuration (with elevation of hypochondria and hysteria scales, the depression scale being somewhat lower); and group 2 (n = 13) with elevation of depression and of other MMPI scales. One patient had no scale elevation. STAI 1,2 scores were high in both groups. Several psychosomatic symptoms and some migraine features were present in almost all patients. Occurrence, severity, and duration of headache were recorded regularly and the MMPI and the STAI administered again after treatment. Improvement of headaches and a decrease of several MMPI and STAI 2 scores were observed. However, 12 of 20 patients showed a conversion V configuration after treatment. It is concluded that chronic daily headache was transformed migraine in most cases and was accompanied by anxiety levels in all patients and hysteric traits in some. With time, these patients may develop a depressive disorder. After treatment, hysterical traits are still present at a lower level in those showing these traits before treatment and may be unmasked in those that had depression.
Forty-one recurrent tension headache sufferers were randomly assigned to either cognitive-behavioral therapy (administered in a primarily home-based treatment protocol) or to amitriptyline therapy (with dosage individualized at 25, 50, or 75 mg/day). Cognitive-behavioral therapy and amitriptyline each yielded clinically significant improvements in headache activity, both when improvement was assessed with patient daily recordings (56% and 27% reduction in headache index, respectively), and when improvement was assessed with neurologist ratings of clinical improvement (94% and 69% of patients rated at least moderately improved, respectively). In instances where differences in treatment effectiveness were observed (headache index, somatic complaints, perceptions of control of headache activity), cognitive-behavioral therapy yielded somewhat more positive outcomes than did amitriptyline. Neither treatment, however, eliminated headache problems.
CONTEXT Sexual dysfunction is a common adverse effect of antidepressants that frequently results in treatment noncompliance. OBJECTIVE To assess the efficacy of sildenafil citrate in men with sexual dysfunction associated with the use of selective and nonselective serotonin reuptake inhibitor (SRI) antidepressants. DESIGN, SETTING, AND PATIENTS Prospective, parallel-group, randomized, double-blind, placebo-controlled trial conducted between November 1, 2000, and January 1, 2001, at 3 US university medical centers among 90 male outpatients (mean [SD] age, 45 [8] years) with major depression in remission and sexual dysfunction associated with SRI antidepressant treatment. INTERVENTION Patients were randomly assigned to take sildenafil (n = 45) or placebo (n = 45) at a flexible dose starting at 50 mg and adjustable to 100 mg before sexual activity for 6 weeks. MAIN OUTCOME MEASURES The primary outcome measure was score on the Clinical Global Impression-Sexual Function (CGI-SF); secondary measures were scores on the International Index of Erectile Function, Arizona Sexual Experience Scale, Massachusetts General Hospital-Sexual Functioning Questionnaire, and Hamilton Rating Scale for Depression (HAM-D). RESULTS Among the 90 randomized patients, 93% (83/89) of patients treated per protocol took at least 1 dose of study drug and 85% (76/89) completed week 6 end-point assessments with last observation carried forward analyses. At a CGI-SF score of 2 or lower, 54.5% (24/44) of sildenafil compared with 4.4% (2/45) of placebo patients were much or very much improved (P<.001). Erectile function, arousal, ejaculation, orgasm, and overall satisfaction domain measures improved significantly in sildenafil compared with placebo patients. Mean depression scores remained consistent with remission (HAM-D score < or =10) in both groups for the study duration. CONCLUSION In our study, sildenafil effectively improved erectile function and other aspects of sexual function in men with sexual dysfunction associated with the use of SRI antidepressants. These improvements may allow patients to maintain adherence with effective antidepressant treatment.
BACKGROUND Acupuncture has become a popular complementary and alternative treatment approach. This review examined the randomized controlled trials (RCTs) examining the effects of acupuncture treatment of depression. METHODS RCTs of the treatment of depression with acupuncture were located using MEDLINE, Allied and Complementary Medicine and the Cochrane Central Register of Controlled Trials. The methodology of RCTs was assessed using the Jadad criteria, and elements of research design, i.e., randomization, blinding, assessment of attrition rates, were quantified for systematic comparisons among studies. RESULTS Among the 9 RCTs examined, five were deemed to be of low quality based upon Jadad criteria. The odds ratios derived from comparing acupuncture with control conditions within the RCTs suggests some evidence for the utility of acupuncture in depression. General trends suggest that acupuncture modalities were as effective as antidepressants employed for treatment of depression in the limited studies available for comparison. However, placebo acupuncture treatment was often no different from intended verum acupuncture. LIMITATIONS The RCTs extracted were limited by small sample sizes, imprecise enrollment criteria, problems with randomization, blinding, brief duration of study and lack of longitudinal follow-up. CONCLUSIONS Despite the findings that the odds ratios of existing literature suggest a role for acupuncture in the treatment of depression, the evidence thus far is inconclusive. However, efforts are being made to standardize complementary approaches to treat depression, and further systematized research into their use is warranted.
OBJECTIVE To observe the effects on post-stroke depression treated with acupuncture at the acu points based on ziwuliuzhu (the midnight-noon ebb-flow theory). METHODS Ninety-three patients were randomized into a comprehensive group, a ziwuliuzhu group and a prozac group, 31 cases in each group. In the ziwuliuzhu group, acupuncture was applied to the acupoints based on ziwuliuzhu, once a day, 5 times in a week. In the prozac group, fluoxertine hydrochloride (prozac) was prescribed for oral administration, once a day, 20 mg each time. In the comprehensive group, acupuncture based on ziwuliuzhu combined with the oral administration of prozac were adopted and the treatment frequency was the same as the ziwuliuzhu group and the prozac group. The 4-week treatment was taken as one session in the three groups and 6 sessions were required totally. The clinical efficacy and the Hamilton depression rating scale (HAMD) score and the adverse reaction were compared among the 3 groups. RESULTS The total effective rate was 96.8% (30/31) in the comprehensive group, better than 83.9% (26/31) in the ziwuliuzhu group and 80. 6% (25/31) in the prozac group (both P<0.05). In 4, 12 and 24 weeks of treatment, HAMD score was lower significantly than that before the treatment in the three groups (all P<0.05), and the score in the comprehensive group at each time point after treatment was lower than the other two groups (all P<0.05). In 4 and 12 weeks of treatment, there were not different significantly between the ziwuliuzhu group and the prozac group (both P>0.05). In 24 weeks of treatment, HAMD score in the ziwuliuzhu group was lower than that in the prozac group (P<0.05). For the adverse reaction, there were 2 cases in the comprehensive group, 6 cases in the prozac group and 0 case in the ziwzuliuzhu group. CONCLUSION The comprehensive therapy of acupuncture at the acupoints based on ziwuliuzhu and oral administration of prozac is superior to either the simple oral administration of prozac or the ziwuliuzhu acu-puncture in terms of clinical efficacy and the improvements in depressive state. Regarding the clinical efficacy, the impact of simple ziwuliuzhu acupuncture is not different significantly as compared with the simple oral administration of prozac, but it is better than the simple oral administration of prozac in terms of the long-term HAMD score and safety.
The term antidepressant refers to a drug that helps to rectify specific biological abnormalities that give rise to the symptoms of depression. This exemplifies what we have called the “disease-centred” model of psychotropic drug action [ 1]. Modelled on paradigmatic situations in general medicine—such as the use of insulin in diabetes, antibiotics in infectious disease, chemotherapy in cancer—the disease-centred model suggests that antidepressants help restore normal functioning by acting on the neuropathology of depression or of depressive symptoms. In contrast, we propose in this Essay that an alternative “drug-centred” model can better explain observed drug effects in psychiatric conditions. This drug-centred model suggests that instead of relieving a hypothetical biochemical abnormality, drugs themselves cause abnormal states, which may coincidentally relieve psychiatric symptoms ( Table 1). Alcohol's disinhibiting effects may relieve symptoms of social phobia, but that does not imply that alcohol corrects a chemical imbalance underlying social phobia. Sedation may lessen high arousal, present in many acute psychiatric situations. Drugs that induce indifference, such as neuroleptics or opiates, may help reduce the distress of acute psychotic symptoms. Low-dose stimulants may help improve attention and concentration in the short term. Table 1    Main Assumptions of Two Models of Psychotropic Drug Action The disease-centred model in psychiatry leads researchers to infer antidepressant effects from patients' scores on symptom rating scales presumed to assess the manifestations of the disease. The drug-centred model, on the other hand, suggests that physiological and subjective effects of drugs should be examined in their own right. These effects include various forms of sedation, stimulation, and a plethora of biopsychological states. Depending on individual inclination and context (including a person's emotional state upon drug ingestion), intoxication with some drugs produces euphoria or mood elevation. Because tolerance develops, however, euphoriant effects do not persist with long-term use. If antidepressants or any other psychotropic drugs could be shown to have mood-elevating effects that were long-term and not diminished by being in a depressed emotional state, this would distinguish them from psychotropic drugs that cause euphoria and might prove uniquely useful in depressed patients (see Sidebar).
Serotonin signaling suppresses generation of amyloid-β (Aβ) in vitro and in animal models of Alzheimer’s disease (AD). We show that in an aged transgenic AD mouse model (APP/PS1 plaque-bearing mice), the antidepressant citalopram, a selective serotonin reuptake inhibitor, decreased Aβ in brain interstitial fluid in a dose-dependent manner. Growth of individual amyloid plaques was assessed in plaque-bearing mice that were chronically administered citalopram. Citalopram arrested the growth of preexisting plaques and reduced the appearance of new plaques by 78%. In healthy human volunteers, citalopram’s effects on Aβ production and Aβ concentrations in cerebrospinal fluid (CSF) were measured prospectively using stable isotope labeling kinetics, with CSF sampling during acute dosing of citalopram. Aβ production in CSF was slowed by 37% in the citalopram group compared to placebo. This change was associated with a 38% decrease in total CSF Aβ concentrations in the drug-treated group. The ability to safely decrease Aβ concentrations is potentially important as a preventive strategy for AD. This study demonstrates key target engagement for future AD prevention trials.
PURPOSE This study assessed psychiatric medications and their potential lethality in a representative sample of suicide attempts. MATERIALS AND METHODS During 1996-98, 563 suicide attempts were studied in a general hospital in Madrid (Spain). Medication overdose was used in 456 suicide attempts (81%). The ratio between dose taken and maximum prescription dose recommended was used to evaluate the medication toxicity. RESULTS Benzodiazepines were the drugs most often used in self-poisoning (65% of overdoses), followed by new antidepressants (11%), tricyclic antidepressants (TCAs) (10%), and antipsychotics (8%). An overdose with any of the three latter psychiatric medications was significantly more frequent in patients prescribed those medications. The overdoses for TCA were potentially lethal in 47% of the cases. However, all patients who overdosed on psychiatric medications recovered well and were discharged without any sequelae. DISCUSSION This study suggests that psychiatric medications, particularly benzodiazepines, new antidepressants and antipsychotics, are relatively safe when they are used for self-poisoning. If patients with mental illnesses are under treated, there is a clear and documented higher risk for suicide. CONCLUSION It is better to prescribe psychiatric medications, particularly the new ones, rather than withhold them due to an exaggerated fear of a lethal overdose
CONTEXT Atypical antipsychotic medications are widely used to treat delusions, aggression, and agitation in people with Alzheimer disease and other dementia; however, concerns have arisen about the increased risk for cerebrovascular adverse events, rapid cognitive decline, and mortality with their use. OBJECTIVE To assess the evidence for increased mortality from atypical antipsychotic drug treatment for people with dementia. DATA SOURCES MEDLINE (1966 to April 2005), the Cochrane Controlled Trials Register (2005, Issue 1), meetings presentations (1997-2004), and information from the sponsors were searched using the terms for atypical antipsychotic drugs (aripiprazole, clozapine, olanzapine, quetiapine, risperidone, and ziprasidone), dementia, Alzheimer disease, and clinical trial. STUDY SELECTION Published and unpublished randomized placebo-controlled, parallel-group clinical trials of atypical antipsychotic drugs marketed in the United States to treat patients with Alzheimer disease or dementia were selected by consensus of the authors. DATA EXTRACTION Trials, baseline characteristics, outcomes, all-cause dropouts, and deaths were extracted by one reviewer; treatment exposure was obtained or estimated. Data were checked by a second reviewer. DATA SYNTHESIS Fifteen trials (9 unpublished), generally 10 to 12 weeks in duration, including 16 contrasts of atypical antipsychotic drugs with placebo met criteria (aripiprazole [n = 3], olanzapine [n = 5], quetiapine [n = 3], risperidone [n = 5]). A total of 3353 patients were randomized to study drug and 1757 were randomized to placebo. Outcomes were assessed using standard methods (with random- or fixed-effects models) to calculate odds ratios (ORs) and risk differences based on patients randomized and relative risks based on total exposure to treatment. There were no differences in dropouts. Death occurred more often among patients randomized to drugs (118 [3.5%] vs 40 [2.3%]. The OR by meta-analysis was 1.54; 95% confidence interval [CI], 1.06-2.23; P = .02; and risk difference was 0.01; 95% CI, 0.004-0.02; P = .01). Sensitivity analyses did not show evidence for differential risks for individual drugs, severity, sample selection, or diagnosis. CONCLUSIONS Atypical antipsychotic drugs may be associated with a small increased risk for death compared with placebo. This risk should be considered within the context of medical need for the drugs, efficacy evidence, medical comorbidity, and the efficacy and safety of alternatives. Individual patient analyses modeling survival and causes of death are needed.
OBJECTIVE The purpose of our study was to investigate alterations of white matter integrity in adults with major depressive disorder (MDD) using magnetic resonance imaging (MRI). METHODS We performed diffusion tensor imaging with a 3T MRI scanner on 45 patients with major depression and 45 healthy controls matched for age, sex and education. Using a voxel-based analysis, we measured the fractional anisotropy (FA), and we investigated the differences between the patient and control groups. We examined the correlations between the microstructure abnormalities of white matter and symptom severity, age of illness onset and cumulative illness duration, respectively. RESULTS We found a significant decrease in FA in the left hemisphere, including the anterior limb of the internal capsule and the inferior parietal portion of the superior longitudinal fasciculus, in patients with MDD compared with healthy controls. Diffusion tensor imaging measures in the left anterior limb of the internal capsule were negatively related to the severity of depressive symptoms, even after we controlled for age and sex. CONCLUSION Our findings provide new evidence of microstructural changes of white matter in non-late-onset adult depression. Our results complement those observed in late-life depression and support the hypothesis that the disruption of cortical- subcortical circuit integrity may be involved in the etiology of major depressive disorder.
Clinical evidence suggests that chronic daily headache (CDH) occurs in association with psychopathologies: previous studies have focused particularly on migraine. To evaluate this association, we studied, using the DSM-IIIR criteria, a population of 88 patients (18M, 70F) affected by CDH (mean duration 7.4 +/- 8.7 years). We documented the presence of a psychiatric disorder in 90% of this population. The most frequent diagnosis was a comorbidity of anxiety and mood disorders. The comorbidity of psychiatric disorders and headache has important implications as far as treatment is concerned.
Two hundred patients who were taking daily symptomatic or immediate relief medications, often in excessive quantities, yet suffering from daily or near daily severe headaches were studied. One hundred and sixteen (58%) of them were also taking concomitant prophylactic medications and they were ineffective. Low tyramine, low caffeine dietary instructions and biofeedback training were given to all patients. The effect of continuing symptomatic medications, discontinuing symptomatic medications, and adding or changing prophylactic medications were studied in the various treatment groups. It is concluded that; 1.) Daily use of symptomatic or immediate relief medications result in chronic daily headache. 2.) Discontinuing daily symptomatic medications itself result in improvement of headache. 3.) Concomitant use of symptomatic medications nullifies the effect of prophylactic medications. 4.) Discontinuing daily symptomatic medications enhances the beneficial effect of prophylactic medications.
Depression is a mood disorder characterized by complex alterations of neurotransmitters such as serotonin, norepinephrine, and dopamine. In particular, there is substantial evidence of abnormalities in serotonin neurotransmission. Peripheral parameters of serotoninergic transmission, such as the 5-hydroxytryptamine content of plasma and platelets, have been used to identify biochemical alterations related to depression. In recent years, these parameters have also been used to examine the mechanism of action of antidepressive drugs such as the selective serotonin reuptake inhibitors. This study investigated the interaction between the plasma and platelet levels of fluoxetine and serotonin after fluoxetine administration to depressed patients. Twelve patients affected by major depression (according to the DSM-IV criteria) received a single oral dose of fluoxetine in the morning: 5 mg in the first 5 days, 10 mg from day 6 to day 10, and 20 mg from day 11 to day 40. Blood samples were collected at 0, 7, 10, and 24 hours after drug administration on the day 1 of fluoxetine 5 mg and on the 1st and the 30th day of fluoxetine 20 mg (days 11 and 40 of treatment, respectively). Plasma fluoxetine and serotonin levels increased after drug administration, reaching the highest levels on the 30th day of fluoxetine 20 mg. Fluoxetine levels were also detectable in platelets, with a time variation similar to plasma values. Platelet serotonin levels decreased after drug administration, and the lowest values were observed on the 30th day of fluoxetine 20 mg.
Twenty-seven migraine headache patients were divided into three equal groups which received thermal biofeedback, frontalis EMG biofeedback, or relaxation training. Training was given under "massed" practice conditions (nine sessions per week) and consisted of 18 training sessions and six test-generalisation sessions. While improvements in headaches were observed in all groups, the best improvements took place in the thermal biofeedback group, which had almost complete elimination of migraine attacks by the end of training, and maintained that performance as long as six months after training. Examination of the patterns of skin temperature and EMG changes in the three groups over the course of training also points to a relationship between skin temperature control and reduction in migraine headache symptomatology, and suggests that this relationship is worthy of further investigation.

There has never been a book on headache that came close to that of the late Harold Wolff. The second edition was published 10 years ago; it was and is a masterpiece of writing, an exhaustive yet engrossing delineation of Wolff's long study and understanding of headache. The new edition, revised by Dalessio, serves to bring certain aspects of headache up to date, most of them having to do with drug therapy. The emphasis on total therapy rather than simply drug therapy has been preserved, however. Dalessio has altered slightly the form of the book, although the "new chapters" on cluster headache and trigeminal neuralgia are merely transplants from other sections of the original. Migraine, the main part of the book, has been reshaped, with some anecdotal portions removed, but little has been added. It is of interest that nothing in the section on observations of methysergide (UML-491 in Wolff's
OBJECTIVE We explored the subjective effects associated with olanzapine, risperidone and older antipsychotics. METHOD We conducted a content analysis of an Internet database of comments about prescribed medications. RESULTS We analysed 223 comments on risperidone, 170 on olanzapine and 46 relating to three older antipsychotics. The predominant subjective effects produced by all drugs consisted of sedation, cognitive impairment and emotional flattening or indifference. Connections appeared between these effects and Parkinsonian-like symptoms with the older drugs, sexual impairment with risperidone and metabolic effects with olanzapine. The experience of akathisia was frequently linked to suicidal thoughts. Some respondents described how the drugs' subjective effects helped to reduce symptoms of mania, psychosis and anxiety. CONCLUSION The generalisability of Internet data is uncertain. However, the data suggest that adverse subjective effects play a central role in the experience of taking antipsychotic drugs and may be related to the drugs' desired benefits.
OBJECTIVE To observe the clinical effects of acupuncture combined with auricular point sticking based on the western medication for post stroke depression (PSD). METHODS Sixty patients with PSD were randomly assigned into an acupuncture plus auricular application group (a combination group) and a medication group, 30 cases in each one. 20 mg paroxetine hydrochloride was prescribed orally in the medication group, once a day for continuous 8 weeks. Based on the above treatment, 30-minute acupuncture was used in the combination group for 8 weeks at Baihui (GV 20), Sishencong (EX-HN 1), Shenting (GV 24), Yintang (GV 29), Shenmen (HT 7), Neiguan (PC 6), Taichong (LR 3), Hegu (LI 4), Zusanli (ST 36), Sanyinjiao (SP 6) and Fenglong (ST 40), once the other day and three times a week. Auricular point sticking therapy for 8 weeks was applied at shenmen (TF4), pizhixia (AT4), xin (CO15), and gan (CO12), with pressing 3 times a day and once 3-5 days. The total score and each factor scores of Hamilton's depression scale (HAMD) were observed in the two groups before and after treatment, and Asberg's antidepressant side-effect rating scale (SERS) and clinical effect were evaluated. RESULTS After treatment, the total HAMD scores of the two groups decreased compared with those before treatment (both P<0.05), with better effect in the combination group (P<0.05). The scores of the combination group after treatment were lower than those in the medication group, including the anxiety/somatization factor, sleep disturbance factor, hopelessness factor (all P<0.05). The total effective rate of the combination group was 86.7% (26/30), which was better than 66.7% (20/30) of the medication group (P<0.05). The SERS score of the combination group was lower than that of the medication group (P<0.05). CONCLUSIONS Acupuncture combined with auricular point sticking can improve the clinical symptoms and are effective and safe for PSD.
BACKGROUND The aim of the study was to provide data on the relative frequency of reported symptoms in travelers using chloroquine, chloroquine plus proguanil, and mefloquine. METHOD The study was an open, nonrandomized study recording self-reported events in travelers recruited consecutively from two travel clinics in Copenhagen, Denmark. The main outcome measures were the relative proportion of travelers reporting particular symptoms in the three prophylaxis groups, compliance, hospitalization and premature termination of the travel. RESULTS From May 1996 to April 1998 5, 446 travelers were included and 4,158 questionnaires (76.3%) returned. Compliance was significantly better in mefloquine users with 83.3% of short term travelers compared to 76.3% in chloroquine plus proguanil users. Also, 84.8%, 59.3% and 69.5% using chloroquine, chloroquine plus proguanil, and mefloquine respectively reported no symptoms and 0.6%, 1.1% and 2.8% reported "unacceptable" symptoms. Compared to chloroquine, mefloquine users had a significantly higher risk of reporting depression, RR 5.06 (95% CI 2.71 - 9.45), "strange thoughts," RR 6.36 (95% CI 2.52 - 16.05) and altered spatial perception, RR 3.00 (95% CI 1.41 - 6.41). CONCLUSION Overall mefloquine is tolerated at least as well as chloroquine plus proguanil and shows better compliance, however, symptoms related to the central nervous system are more prevalent in mefloquine users and when symptoms develop, they are perceived as more severe.
BACKGROUND AND PURPOSE Migraineurs are at increased risk of cerebellar infarcts and supratentorial white matter lesions. The prevalence, frequency, and distribution of infratentorial hyperintense lesions in migraine are unknown. METHODS Migraineurs with aura (n=161), without aura (n=134), and controls (n=140) from a population-based sample of adults (30 to 60 years of age) were evaluated with MRI. RESULTS Infratentorial hyperintensities were identified in 13 of 295 (4.4%) migraineurs and in 1 of 140 (0.7%) controls (P=0.04). Twelve cases had hyperintensities, mostly bilaterally, in the dorsal basis pontis. Those with infratentorial hyperintensities also had supratentorial white matter lesions more often. CONCLUSIONS We found an increased prevalence of infratentorial (mostly pontine) hyperintensities in migraineurs from the general population. This extends the knowledge about vulnerable brain regions and type of lesions in migraine brains. A hemodynamic ischemic pathogenesis is likely, but further research is needed.
OBJECTIVE To measure in vivo, using diffusion tensor magnetic resonance imaging (DT-MRI) the extent of pathological damage of normal appearing brain tissue (NABT) from patients with migraine. METHODS Dual echo and DT-MRI scans of the brain were acquired from 34 patients with migraine and 17 sex and age matched healthy volunteers. Mean diffusivity (MD) and fractional anisotropy (FA) histograms of the NABT were obtained from all subjects and the histograms' peak heights and average NABT MD and FA measured. When present, average MD and FA values of T2 visible lesions were also measured. RESULTS In comparison with healthy volunteers, patients with migraine had lower MD histogram peak height (p=0.02) of the NABT. No differences were found in FA histogram derived metrics between migraine patients and healthy subjects. No difference was found for any MD and FA histogram derived metrics between migraine patients with and without brain MRI lesions, and between patients with and without aura. CONCLUSIONS This study shows that, although brain damage may extend beyond T2 weighted abnormalities in patients with migraine, the severity of these "occult" changes is mild compared with that found in other diseases associated with white matter abnormality.
