BACKGROUND Chocolate consumption has long been associated with enjoyment and pleasure. Popular claims confer on chocolate the properties of being a stimulant, relaxant, euphoriant, aphrodisiac, tonic and antidepressant. The last claim stimulated this review. METHOD We review chocolate's properties and the principal hypotheses addressing its claimed mood(More)
While differing anxiety disorders have been reported to have quite variable impact on outcome following an acute coronary syndrome (ACS), a recent study quantified generalized anxiety disorder (GAD) as having a distinctly negative impact. We examined anxiety disorder status at baseline for any differential five-year impact on cardiac outcome following(More)
It is commonly suggested that a female preponderance in depression is universal and substantial. This review considers that proposition and explanatory factors. The view that depression rates are universally higher in women is challenged with exceptions to the proposition helping clarify candidate explanations. 'Real' and artefactual explanations for any(More)
OBJECTIVE As the authors have observed clinical benefit from the psychostimulants methylphenidate and dexamphetamine for treating resistant melancholic and bipolar depression, those drugs were evaluated in a consecutively recruited sample of 50 such patients. METHOD Patients (27 bipolar, 23 unipolar) received either methylphenidate (n = 44) or(More)
OBJECTIVE Reflecting increased scientific interest in any nutritional contribution to the onset and treatment of mood disorders, we overview research into two neurotransmitter precursors - the amino acids tryptophan and tyrosine - particularly examining whether any deficiency increases risk to depression and whether those amino acids have any antidepressant(More)
OBJECTIVE While there has long been interest in any nutritional contribution to the onset and treatment of mood disorders, there has been increasing scientific evaluation of several candidate nutritional and dietary factors in recent years. In this paper, we overview research into any vitamin D insufficiency and deficiency contribution to depression. (More)
As deficiencies in n-3 PUFAs have been linked separately to depression and to cardiovascular disease, they could act as a higher order variable contributing to the established link between depression and cardiovascular disease. We therefore examine the relationship between depression and omega-3 polyunsaturated fatty acids (n-3 PUFA), including total n-3(More)
BACKGROUND Conflicting findings have emerged from studies examining the impact of depression on death and readmission following a coronary event, possibly reflecting differences in the measurement of "depression" and the onset of depression in relation to the coronary event. The aim of this study was to examine the relationship between the timing of the(More)
Unipolar depression is more common in women than men. We pursue a unifying explanation for the sex difference in the incidence of depression that emerges at puberty and is unlikely to be fully explained as an artifact or as a result of socialization or contemporary sex roles. Because symptomatic anxiety disorders show a similar female preponderance in(More)
BACKGROUND A recent US study presented data suggesting that depressed women are more likely to respond to selective serotonin reuptake inhibitor (SSRI) than tricyclic (TCA) antidepressant drug therapies. We have undertaken replication studies in two independent databases. METHOD We have examined for gender differences in SSRI and TCA antidepressant(More)
