JOHN MANN One of the first neurochemical theories of depression was past 20 years is highly debated, in terms of greater efficacy the monoamine deficiency hypothesis (139,143,153). If improvements are evident the past 30 years, this hypothesis has been the most scruti- in antidepressant medications, then they are as a result of nized of any theories regarding the biology of depression. For this reason, as research on that most, if not all, antidepressant drug treatments produce depression biology progresses into this new century, the their therapeutic antidepressant effects, at least in part, by monoamine hypotheses continue to be among the most modulating monoamine systems (noradrenergic, serotoner- popular biological theories and continue to be heavily inves- gic, and dopaminergic); however, less is known about the tigated and debated. Early attempts to evaluate monoamine systems mood disorders has led to advancements in our understand- in depressive disorders led to diverse and not clearly inte- ing of the role that monoamines play in these disorders.

These theories include HPA axis hyper- logic and neurochemical investigations with high levels of activity (111), the GABA hypothesis (132), the galanin hy- anatomic resolution, use of postmortem brain tissues from pothesis (186), the substance P hypothesis (82), the gluta- psychiatrically characterized subjects, and genetic studies. A substantial portion of the evidence sup- ple system pathology in mood disorders, including abnor- porting these 'other neurotransmitter' theories derives malities of monoamine as well as other neurotransmitter from studies of the pharmacologic and behavioral effects of systems. These approaches and findings have led researchers antidepressant drugs in laboratory animals.

OBSESSIVE-COMPULSIVE DISORDER Introduction th th th Many hotels do not have a 13 floor: after the 12 comes the 14 floor. This is an example of a “superstition”; many healthy individuals have vague superstitions, which they know are “silly”, but they prefer not to transgress. Superstition and Obsessive-compulsive disorder (OCD) are not related, but superstitions and how we respond to them have something of the nature of OCD. Students trained predominantly on inpatient units may see little OCD. This disorder is usually managed on an outpatient basis. Patients are often reluctant 1) to admit to OCD symptoms (which they know are “silly”), and 2) to enter hospitals (where they may catch germs – nor do they wish to be removed from the relative security of their homes and routines). Also, treatment can often be adequately and cost-effectively delivered in office practice. This is a most unusual occurrence, and other factors were probably involved. However, the story illustrates the frustration which can occur in families in which one member is suffering OCD. Epidemiology The British National Psychiatric Morbidity Survey (Torres et al, 2006). Of people with OCD 55% have obsessions only, 11% have compulsions only, and 34% have both obsessions and compulsions. Onset following stressful events, such as pregnancy/childbirth is often reported. Generally, the course is chronic, but with fluctuations (exacerbation and remission). Both, spontaneous remission and progressive deterioration can occur. Obsessions are persistent, intrusive ideas, thoughts, impulses, or images that are experienced as inappropriate and that cause anxiety or distress. The individual is able to recognise that the obsessions/events are the product of his/her own mind and not imposed from outside (that is, they are not related the psychotic experience of thought insertion or control).
