Event-related potentials during a two-tone discrimination task were recorded in 24 schizophrenic patients, 16 depressed patients and 59 control subjects. Recordings were made when patients were medication-free. Fourteen schizophrenic and 13 depressed patients were retested at 1 and 4 weeks after the start of treatment, and 13 schizophrenic patients were(More)
We report an extensive study which compares cognitive therapy, antidepressant drugs and a combination of these two, in depressed patients seen either in general practice or an out-patient department. One-hundred and forty patients were screened for primary major depression and 64 patients completed the trial. All were rated on seven measures of mood,(More)
To determine whether high plasma cortisol concentrations are a distinctive feature of depression or whether plasma cortisol is also elevated in other forms of psychosis, cortisol concentrations were measured in 59 patients with acute functional psychoses, six non-psychotic depressed patients and 37 control subjects, all free of antidepressant and(More)
Plasma prolactin, growth hormone, cortisol, luteinising-hormone-releasing hormone (LHRH), thyrotropin-releasing hormone (TRH), and nicotine and oestrogen stimulated neurophysin (NSN and ESN) were measured before and for 6 min after electroconvulsive therapy (ECT) in eight women with severe electroconvulsive therapy (ECT) in eight women with severe(More)
Growth hormone and prolactin (PRL) responses to 0.75 mg of apomorphine hydrochloride were measured in 19 newly admitted psychotic patients who had been untreated by neuroleptic or antidepressant drugs for at least nine months. We compared hormonal responses between subgroups of patients who were distinguished using the diagnostic criteria of Feighner et al(More)
The number of glucocorticoid receptor sites in lymphocytes was estimated and plasma cortisol concentrations measured in 17 depressed patients, 12 patients with chronic schizophrenia, and 31 healthy control subjects. The number of receptor sites was significantly lower in the depressed patients than in either the controls or the patients with chronic(More)
Plasma concentrations of prolactin, growth hormone, cortisol, TSH, and the neurophysins were measured over 17 hours in 98 newly admitted psychiatric patients and 35 control subjects. Seventy patients had been free of psychotropic medication for three months. Patients with schizoaffective mania (SAM) differed significantly from control subjects by increased(More)
Physostigmine (0.25 mg-1 mg), arecoline (2 and 4 mg) and saline were administered intravenously over 30 minutes in a randomized double blind design to 11 patients with a clinical diagnosis of Alzheimer presenile dementia. Significant improvement was seen on a picture recognition test with physostigmine 0.375 mg and arecholine 4 mg. A trend towards(More)
The P300 (P3) and other long latency auditory evoked potentials were measured in 15 patients with presenile dementia Alzheimer type (ATD), 16 patients with alcoholic Korsakoff syndrome (KS) and 23 age-matched control subjects. All were drug free for at least four weeks before testing. The latency of the P3 was significantly longer and the amplitude(More)
Hypersecretion of cortisol is associated with depression. Because corticosterone may show greater responsiveness than cortisol to exogenous ACTH in depression and it has behavioural effects in rodents, we determined whether depression is also associated with hypersecretion of corticosterone. Both cortisol and corticosterone were significantly elevated in(More)
