Although many of the physiological functions of neurosteroids are currently unknown, evidence suggests that these endogenous molecules may play a role in the pathophysiology of psychiatric disorders and treatment strategies. Neurosteroids have been linked to SSRI action and may be relevant to antipsychotic drug effects. Do neurosteroids have neuroprotective properties or HPA axis effects?

The first magnetic resonance imaging studies in schizophrenia began to appear in the literature in 1984. These studies confirmed earlier theories and also contributed new findings such as changes in size of the hippocampus, amygdala, corpus callosum and so on in patients with schizophrenia. What other neuroimaging techniques are being used? What do recent studies show regarding the neuroanatomic abnormalities found in patients with schizophrenia?

By definition, gambling is the process of placing something of value (usually money) at risk in the hopes of gaining something of greater value (Potenza et al., 2001). It is a human behavior that has persisted for millennia; some of humanity's earliest historical accounts document gambling as a practice of ancient civilizations (France, 1902; Potenza and Charney, 2001).

In examining the demographics of a state Medicaid population, we found that members of ethnic minorities, rural residents, women, and patients aged 45 years and older were more likely to receive first-generation antipsychotic medications than the newer, second-generation agents, which have a more favorable side-effect profile.

Patients with schizophrenia have a high risk of committing suicide. Between 25% and 50% attempt suicide at least once, resulting in approximately 3,600 successful attempts each year in the United States. What are the risk factors for suicide one should look for in treating patients with schizophrenia? Herbert Y. Meltzer, M.D., discusses the issue and offers warning signs.

Evaluations of new drugs, new dosage formulations and new applications for currently approved drugs were a substantial portion of the scientific program at the 40th annual NCDEU meeting, which is sponsored by the National Institute of Mental Health.

(The following are highlights of new research presented at the 2000 American Psychiatric Association Annual Meeting. Additional highlights can be found in "APA Meeting Highlights New Research," in the February issue of Psychiatric Times, p23-Ed.)

Because there is intense pressure by managed care to shorten the hospital stay for patients with anorexia nervosa, there is a need for partial-hospitalization treatment programs. Since patients gain an average of 0.5 lbs/week to 1.5 lbs/week in these less-monitored programs, as opposed to 2 lbs/week to 3 lbs/week in the inpatient behavioral specialty programs, Angela S. Guarda, M.D., and colleagues (Symposium 21B) described components that would improve the partial treatment program.
