Although eating disorders have been considered to be largely sociocultural in origin, findings from family, twin and molecular genetic studies conducted during the last decade are refuting that perspective. Recent studies have had significant success in isolating specific chromosome regions that may harbor susceptibility loci for anorexia and bulimia nervosa and are helping to shed light on the degree of heritability of eating disorders.
Assessing and treating patients with suicidal behavior is not an easy task. Acts of suicide cannot be predicted; the best a psychiatrist can hope for is the ability to identify a patient's risk factors and reduce them.

Psychopharmacologic management has become increasingly complex, and physicians run the risk of precipitating drug-drug interactions when certain drugs interact via the cytochrome P450 system. In addition, the P-glycoprotein transporter may play a role in certain drug-drug interactions. While physicians currently rely on Web sites and textbooks to avoid potentially morbid and lethal interactions, electronic medical records may play a crucial role in the future.
Anorexia nervosa, bulimia nervosa and binge-eating disorder remain challenging disorders for the practicing psychiatrist. While psychopharmacological agents play an important role in the overall treatment of eating disorders, current empirical evidence does not support their sole use. A recipe consisting of evidence-based psychopharmacological agents together with evidence-based psychotherapeutic approaches is usually required for a successful outcome.
According to a large international study, BD-II mixed depression can easily be misdiagnosed as major depressive disorder. Proper assessment and treatment of mixed depression in BD-II could have a positive impact on outcomes in bipolar disorder.

The majority of these individuals are there because community-based treatments are not available, they have co-occurring substance abuse problems or they have previous involvement with the criminal justice system. Partnering with law enforcement agencies is key to devising workable solutions that ensure individuals with mental illnesses get the treatment they need.
