The use of the flash and pattern reversal visual evoked potential (VEP) in the diagnosis of primary presenile dementia was investigated. The results from 20 patients with primary presenile dementia were compared with those from a control group of normals of equivalent age and from a control group of 20 patients with cortical atrophy but no dementia.(More)
Flash, pattern reversal and pattern onset-offset VEPs were recorded in 17 patients with a clinical diagnosis of presenile dementia. The results were compared with those from two control groups--17 normal volunteers of equivalent ages and 17 patients from the same psychiatric hospital with affective disorders but no clinical evidence of dementia. The flash(More)
Primary presenile dementia slows the major positive component of the visual evoked potential to flash stimulation but does not affect the visual evoked potential to patterned stimulation. The progressive effect of Alzheimer's disease was followed in a 58 year old woman over three and a half years from the development of the earliest symptoms to complete(More)
The depressive Attributional Style Questionnaire (Peterson et al., 1982) and the Hassles and Uplifts Questionnaire (Kanner et al., 1981) were administered to melancholic and non-melancholic depressed patients (matched for severity according to a doctors/nurses rating scale), and to non-depressed volunteers. Compared to the other two groups, melancholic(More)
Ninety-one patients with forgetfulness, confusion and depression were referred for visual evoked potential and electroencephalographic investigation. The patients were subdivided, on clinical symptoms alone, into a group of 41 with evidence of dementia and a patient control group of 50 with effective disorders. A second control group of 30 normal volunteers(More)
Serum total androgens were estimated by radioimmunoassay on blood samples of treatment-seeking homosexuals and heterosexual controls. There was no significant difference in androgen levels between the homosexual and control group, nor was there any relationship between androgen levels and response to treatment. These results suggest that androgen levels(More)
