Eating disorder or oesophageal achalasia during adolescence: diagnostic difficulties.

Marine was a fourteen and a half-year-old adolescent female hospitalized for an eating disorder (ED) of the anorexic type with purging behaviors. She has had a complicated life course, made up of disruptions and discontinuities, both family and school. Since the age of five, Marine had been intermittently treated in psychiatry for a diagnosis of oppositional defiant disorder.

Mood disorders in eating disorder patients: Prevalence and chronology of ONSET.

Objectives: In a clinical population, we estimated the frequency of mood disorders among 271 patients suffering from Anorexia Nervosa (AN) and Bulimia Nervosa (BN) in comparison to a control group matched for age and gender.

Method: The frequency of mood disorders was measured using the Mini International Neuropsychiatric Interview (MINI), DSM-IV version.

Results: Mood disorders were more frequent among eating disorder (ED) patients than among controls, with a global prevalence of the order of 80% for each ED group.

Clonidine pre-treatment fails to block acute smoking-induced EEG arousal/mood in cigarette smokers.

Given the arousal eliciting actions of smoking and nicotine, and the contributing role of noradrenaline in brain arousal systems, this study examined the neuroelectric and affective correlates of cigarette smoking following acute pre-treatment with the alpha 2-noradrenergic auto-receptor agonist, clonidine. In a double-blind placebo-controlled crossover design, quantitative electroencephalography (EEG), mood, and smoking withdrawal symptoms were assessed in 12 overnight smoking abstinence smokers, before and after sham and cigarette smoking. Orally administered clonidine (0.

Effects of stimulus modality and response mode on the P300 event-related potential differentiation of young and elderly adults.

The P300 event-related brain potential (ERP) was examined in 14 young (20 - 29 years of age) and 16 elderly (60 - 82 years of age) adult subjects during the performance of auditory and visual discrimination tasks requiring silent counting or key pressing in response to target stimuli. P300 latencies were longer in elderly (vs young) adults and in visual (vs auditory) tasks, and visual tasks elicited larger P300 amplitudes than auditory tasks in both age groups. Neither stimulus modality nor response mode affected P300 differentiation of young and elderly subjects.

World wide use of psychotropic drugs in child and adolescent psychiatric disorders.

1. Questionnaires were mailed to child psychiatrists world wide to obtain more precise information on views and approaches to the diagnosis and treatment of childhood psychiatric disorders. 2.

Subjective and brain-evoked responses to electrical pain stimulation: effects of cigarette smoking and warning condition.

Infrahuman studies employing behavioral indices of pain reactivity have supported a central antinociceptive action of nicotine which appears to be selective and dependent on the class of pain elicited. Human investigations employing subjectively based ratings and judgments of pain intensity have been less conclusive regarding the painfulness of stimuli following nicotine/smoking administration. As the more objective brain-evoked potential (EP) measure has been shown to reflect pain intensity and to be sensitive to a variety of analgesics, this study attempted to examine, together with subjective responses, the effects of cigarette smoking on EPs to pain stimuli administered under varying warning conditions.
