Cephalalgiaphobia: a possible specific phobia of illness.

Psychiatric comorbidity, mainly anxiety and depression, are common in chronic migraine (CM). Phobias are reported by half of CM patients. Phobic avoidance associated with fear of headache or migraine attack has never been adequately described. We describe 12 migraine patients with particular phobic-avoidant behaviours related to their headache attacks, which we classified as a specific illness phobia, coined as cephalalgiaphobia. All patients were women, mean age 42, and all had a migraine diagnosis (11 CM, all overused acute medications). Patients had either a phobia of a headache attack during a pain-free state or a phobia of pain worsening during mild headache episodes. Patients overused acute medication as phobic avoidance. It is a significant problem, associated with distress and impairment, interfering with medical care. Cephalalgiaphobia is a possible specific phobia of illness, possibly linked to progression of migraine to CM and to acute medication overuse headache.

Depression in chronic migraine: Severity and clinical features

INTRODUCTION Chronic migraine (CM) is a common medical condition affecting 2.4% of the general population. Depression is one of the most frequent comorbid disorders in CM. METHOD Seventy patients diagnosed with chronic migraine were studied. All patients evaluated filled out the Beck Depression Inventory (BDI). Depression severity was divided into none or minimal depression, mild, moderate, and severe. RESULTS BDI ranged from 4 to 55, mean 21 +/- 10.7. Moderate or severe depression, were present in 58.7% of the patients. Some degree of depression appeared in 85.8% of patients. The BDI scores correlated with pain intensity (p = 0.02). Severe depression was more frequent in patients with comorbid fibromyalgia and in patients reporting fatigue. CONCLUSION The BDI is an easy tool to access depression in CM patients. Suicide risk assessment is needed in CM patients. Patients with fibromyalgia and fatigue are at even higher risk for severe depression.

Clomipramine, a better reference drug for panic/agoraphobia. I. Effectiveness comparison with imipramine

An 8-week, double-blind, flexible-dose trial comparing low doses of clomipramine (mean=50 mg) with moderate doses of imipramine (mean=113.8 mg and propanteline (active placebo), was carried out in 60 out-patients with panic disorder with or without agoraphobia. Efficacy evaluation included global, anxiety and depression rating scales, and the determination of rates of relapse over up to 10 weeks of single-blind placebo follow-up. Both tricyclics were significantly more effective than propanteline, but clomipramine tended to act faster and more consistently than imipramine on most measures. Given the degree of blindness achieved and the significantly lower doses of clomipramine, this seems a better reference drug than imipramine for clinical trials in panic/agoraphobia.

Validation of the Portuguese version of the Social Adjustment Scale on Brazilian samples

BACKGROUND Social dysfunction is reported in several psychiatric diseases and its evaluation is becoming an important measure of treatment outcome. The aim of this study was to obtain normative data, to test the validity and the ability of the Portuguese version of the Self-Report Social Adjustment Scale (SAS-SR) to detect different clinical conditions. METHODS The Portuguese version of the SAS-SR was applied to a carefully selected non-psychiatric sample, and to depressed, panic, bulimic and cocaine-dependent patients. Depressed and panic patients were evaluated in two different clinical conditions: acutely symptomatic and in remission. RESULTS SAS overall and sub-scale scores of the normal sample were consistently lower than all patient groups, indicating better social adjustment in all areas. Panic patients were impaired to a lower level than depressed and cocaine-dependent patients in overall adjustment. Depressed patients in remission, although in better condition, were still impaired in relation to normal subjects in overall social functioning, leisure time and marital areas. In panic patients in remission, normalization was not achieved in overall functioning, work and marital areas. LIMITATIONS Sample size was small in some groups and the evaluation was cross-sectional. CONCLUSIONS The Portuguese version of SAS-SR is a useful instrument for detecting differences between psychiatric patients and normal subjects and for the evaluation of different clinical conditions, recommending its use in outcome studies.

Fibromyalgia Comorbid with Anxiety Disorders and Depression: Combined Medical and Psychological Treatment

Fibromyalgia is associated with high level of pain and suffering. Lack of diagnosis leads to onerous indirect economic costs. Recent data indicate that fibromyalgia; anxiety disorders, and depression tend to occur as comorbid conditions. They also share some common neurochemical dysfunctions and central nervous system alterations such as hypofunctional serotonergic system and altered reactivity of the hypothalamic-pituitary-adrenal axis. Conversely, functional neuroimaging findings point to different patterns of altered pain processing mechanisms between fibromyalgia and depression. There is no cure for fibromyalgia, and treatment response effect size is usually small to moderate. Treatment should be based on drugs that also target the comorbid psychiatric condition. Combined pharmacotherapy and cognitive-behavior therapy should ideally be offered to all patients. Lifestyle changes, such as physical exercise should be encouraged. The message to patients should be that all forms of pain are true medical conditions and deserve proper care.

Adverse life events and coping skills in panic disorder

UNLABELLED Research literature and clinical experience shows that panic patients are often able to identify stressors that preceded the onset of their first attacks. In this study we investigated the relation between life events, coping skills, and panic disorder. METHODS Forty-tree panic patients were compared with 29 control subjects regarding the occurrence and the impact of stressful life events in a 1-year period preceding the onset of panic attacks using the Social Readjustment Rating Scale and London Life Event and Difficulty Schedule. Coping skills were measured using the Ways of Coping Questionnaire. RESULTS No differences were observed between panic patients and controls regarding the number of reported stressful life events in the previous year. Panic patients compared to controls reported loss of social support as the most meaningful class of events significantly more often. In response to stressful situations, panic patients more often used coping skills judged as ineffective. CONCLUSIONS The present study suggests that the type of life event and the coping skills used in response to them, more than the occurrence of stressful events itself, may be associated with the onset of panic disorder.

Tratamento farmacológico do transtorno de estresse pós-traumático

The authors present a review of pharmacotherapy for posttraumatic stress disorder (PTSD). Only a few controlled clinical trials have been carried out on PTSD, but there is a growing interest on this topic. Antidepressants, specially those with serotonergic activity, appear to provide effective pharmacotherapy for PTSD, as having either a primary therapeutic effect or in association with psychotherapy.

Phobias, other psychiatric comorbidities and chronic migraine

BACKGROUND Comorbidity of chronic migraine (CM) with psychiatric disorders, mostly anxiety and mood disorders, is a well-recognized phenomenon. Phobias are one of the most common anxiety disorders in the general population. Phobias are more common in migraineurs than non-migraineurs. The clinical profile of phobias in CM has never been studied. METHOD We investigated the psychiatric profile in 56 patients with CM using the SCID I/P interview. RESULTS Lifetime criteria for at least one mental disorder was found in 87.5% of the sample; 75% met criteria for at least one lifetime anxiety disorder and 60.7% of our sample fulfilled DSM-IV criteria for lifetime phobic avoidant disorders. Mood and anxiety scores were higher in phobic patients than in non-phobic CM controls. Number of phobias correlated with higher levels of anxiety and depression. CONCLUSION Phobias are common in CM. Its recognition may influence its management. Early treatment may lead to better prognosis.

A dose-finding and discontinuation study of clomipramine in panic disorder

Eighty-one panic disorder patients with or without agoraphobia were treated with flexible doses of clomipramine under single-blind conditions. Fifty-seven (70.3%) reached operational criteria for full remission in 16.2 ± 6.5 weeks, with a mean dose of 89.1 ± 8.2 mg/day. Fifty-four (81%) of them received a continuous post-remission maintenance treatment at full doses of clomipramine for 4–6 months. No patient relapsed during the clomipramine maintenance phase. Their medication was then tappered and discontinued with placebo substitution under double-blind conditions. Fifty-one (63%) patients were followed-up until relapse or recurrence for up to 3 years, with periodic assessments. Three different outcome groups were identified: the first (n = 19, 19; 37.2%) experienced an early/immediate relapse (5.2 ± 4.9 weeks after drug discontinuation); the second group (n= 22, 22; 43.1%) experienced recurrence after 42.9 ± 35 weeks following discontinuation; and the third group (n = 10, 10; 19.6%) remained assymptomatic and functionally well throughout the follow-up. Predictors of early relapse were: (1) higher baseline score in the Beck Depression Inventory; (2) higher global score on the phobic avoidance scale after the full remission criteria; and (3) the need for higher clomipramine doses to reach full remission. The need for long-term or intermittent maintenance for most patients is emphasized.

Panic disorder and exercise avoidance

OBJECTIVES 1) To identify whether patients with panic disorder in general and those with the respiratory subtype in particular actively avoid exercise; 2) to investigate physiological differences in cardiopulmonary function parameters in patients with panic disorder in general, patients with the respiratory subtype of panic disorder, and healthy controls upon exercise challenge. METHODS Patients with panic disorder were classified as having either the respiratory or the non-respiratory subtype. Both groups were compared to controls in terms of exercise avoidance patterns and performance on cardiopulmonary exercise testing. RESULTS Patients with panic disorder exhibited higher exercise avoidance scores and worse performance on cardiopulmonary exercise testing as compared with controls. No differences were found between patients with the respiratory and non-respiratory subtypes. CONCLUSIONS Exercise avoidance is present in panic disorder and is associated with poorer performance on cardiopulmonary exercise testing. These findings are not limited to patients with the respiratory subtype of the disorder.
