Chorea.

Two weeks after starting the oral contraceptive pill, a 16-year-old girl developed increasingly violent chorea and an evolving psychosis with prominent hallucinations, ideas of reference, and paranoia. An erythematous skin rash subsequently developed and Sydenham's chorea (SC) was diagnosed. Following neuroleptic medication and steroids, her chorea and psychosis subsided.

Behavioural treatment of AIDS-focused illness phobia.

Seven cases are described in which the central symptoms were fear of contracting AIDS, avoidance of related cues, rituals and reassurance-seeking. Associated features include previous illness phobias and obsessive-compulsive disorder. Treatment with exposure and response prevention (plus a cognitive session in one case), led to improvement sustained up to three months after discharge, although one patient stopped treatment prematurely.

Psychiatric morbidity in multiple sclerosis: a clinical and MRI study.

This study reports the psychiatric morbidity in 116 patients with definite multiple sclerosis (MS). The presence of brain pathology was investigated using magnetic resonance imaging (MRI). A group of 48 physically disabled controls suffering from rheumatic or neurological conditions not involving the brain was used for comparison.

Cognitive impairment in patients with clinically isolated lesions of the type seen in multiple sclerosis. A psychometric and MRI study.

This study reports the performance on psychometric tests of a group of 48 patients with clinically isolated lesions of the type seen in multiple sclerosis (optic neuritis, brainstem and cord lesions). The cognitive functions studied were: 'IQ deficit', verbal and visual memory, abstracting ability, visual and auditory attention, and naming ability. The presence of brain pathology was investigated by means of magnetic resonance imaging (MRI).

Psychiatric morbidity in patients with clinically isolated lesions of the type seen in multiple sclerosis: a clinical and MRI study.

This study reports the psychiatric morbidity in 76 patients with clinically isolated lesions of the type seen in multiple sclerosis (optic neuritis, brain stem and cord lesions). The presence or absence of brain pathology was investigated using magnetic resonance imaging (MRI). A group of 33 patients suffering from rheumatic and neurological conditions not known to involve the brain was used for comparison.

Magnetic resonance imaging in central nervous system sarcoidosis.

We performed brain MRIs on 21 patients with CNS sarcoidosis. Brain CTs were performed in 18 of these. Parenchymal lesions were seen in 17 of 21 with MRI, compared with 9 of 18 with CT.

Post-ictal psychoses. A clinical and phenomenological description.

Post-ictal psychoses have so far received little attention. The clinical details of 14 cases, diagnosed according to newly formulated criteria, were examined. Psychoses were usually precipitated by a run of seizures and occurred after a lucid interval.

Psychiatric and neurological manifestations in systemic lupus erythematosus.

The frequency and type of psychiatric disease were investigated in 40 patients suffering from systemic lupus erythematosus (SLE) and 27 control subjects with rheumatoid arthritis or inflammatory bowel disease. The psychiatric morbidity at the time of interview was the same in the two groups, but the patients with SLE had experienced more episodes of psychiatric illness in the past, and psychotic symptoms occurred only in this group. Half of the patients with SLE had previous or current evidence of neurological involvement; an association was found between neurological disease and psychotic symptoms in SLE, while anxiety and affective disturbances appeared to be closely related to environmental factors in both patients with SLE and controls.

The effect of moderate blood alcohol levels on T1 and T2 relaxation times in the brains of normal volunteers.

T1 and T2 measurements of the brains of six human volunteers did not change in the presence of moderate blood alcohol levels.
