Coppen A. The biochemistry of the affective disorders. This paper was a review of investigations into the role of neurotransmitters, endocrine factors and electrolytes in the aetiology and treatment of depressive and manic illness. [The Science Citation Index ® (SCI) and the Social Sciences Citation Index™ (SSCI™) indicate that this paper was cited a total(More)
Electrodermal activity was measured in a group of depressive patients and normal controls. Those patients classified as endogenous on the Newcastle Scale had significantly lower skin conductance levels than either the non-endogenous patients or controls. The endogenous depressives also contained significantly more non-responders to the experimental stimuli.(More)
Thirty-two patients who had responded to amitriptyline (150 mg daily) when suffering from a depressive illness were allocated either to receive placebo or to remain on the same medication for one year. Plasma concentrations of the drug were regularly estimated. There was no correlation between plasma concentration and subsequent residual affective(More)
The prevalence of an abnormal response to the dexamethasone suppression test (DST) was examined in 119 in-patients suffering from a major depressive disorder and in 79 normal controls. Only 11 per cent of controls showed an abnormal DST as against 70 per cent of depressed patients. The specificity of the DST was examined by testing patients with other(More)
In a double-blind study the therapeutic efficacy of sulpiride was compared to that of haloperidol--an established neuroleptic agent. A total of 30 female patients with a diagnosis of chronic schizophrenia were initially stabilised on the dosage of haloperidol which produced optimum therapeutic response when given once or twice daily. The patients were then(More)
Kinetic analysis of the transport of 5-HT into the blood platelets of depressed patients and recovered depressive patients has shown that the rate of accumulation of 5-hydroxytryptamine (5-HT) is significantly decreased both before and after recovery from the illness. This abnormality is corrected by both short and long-term lithium treatment. As a(More)
Renal function was examined in 101 patients maintained on sustained-release lithium carbonate for periods ranging from 1 to 12.5 years. A control group of patients with affective disorders who had never been given lithium was also investigated as well as a control group of normal subjects of comparable age and sex. Creatinine clearance, serum creatinine,(More)
Evidence is reviewed indicating that instability in central nervous system handling of 5-hydroxytryptamine may be of primary importance in the pathogenesis of migraine, and that the observed diminution of platelet content and uptake of 5-hydroxytryptamine related to an attack may merely be a reflection of this. The rationale is discussed for selecting(More)
