Pharmacologic and nonpharmacologic therapies both have roles in the treatment of insomnia. The benzodiazepines, when first introduced, were a major improvement over earlier treatments for insomnia in terms of their safety and efficacy. Since then, the nonbenzodiazepine benzodiazepine receptor agonists have been developed, which have provided advantages over the older medications and are currently first-line medication treatment for insomnia. ⋯ Nonpharmacologic therapies can also help patients learn how to fall asleep faster and improve sleep quality. It is important for physicians to teach patients good sleep hygiene as part of their treatment. Cognitive-behavioral therapy is effective in the treatment of insomnia, alone and in combination with pharmacotherapy, but finding a qualified provider can be difficult and the patient must be willing to take the time to learn the therapies and wait for them to show effect.

Since the early 1980s, concern within the psychiatric community about whether antipsychotics are associated with adverse cardiovascular events has grown. In the early 1990s, it became clear that mesoridazine could cause torsades de pointes. More recently, concern has focused on the propensity that some atypical antipsychotics have to prolong corrected QT (QTc) interval and whether this can result in torsades de pointes and sudden death. ⋯ However, identifying when QTc prolongation carries a risk of torsades de pointes remains a problem in developing new drugs. Psychiatric populations are at high risk for cardiovascular disease, and emerging data indicate that some atypical antipsychotics may be associated with cardiovascular adverse events unrelated to QT prolongation. Thus, it is prudent for the psychiatric community to be aware of psychiatric patients' baseline medical condition and their risk status for cardiovascular disease.

Bipolar II disorder is frequently misdiagnosed as major depressive disorder. In particular, correct diagnosis of bipolar II disorder may be delayed by years due to the predominance of depressive symptoms and the relative subtlety of hypomania, which may manifest only briefly and without elevated mood. The prevalence of bipolar II disorder varies from 0.5% to about 5% depending on the criteria used. ⋯ Acute bipolar II depression could be treated with a combination of a mood stabilizer plus an antidepressant or pramipexole and in rare cases with antidepressant monotherapy. Hypomania will likely respond to monotherapy with antimanic agents. Adjunctive psychosocial treatments may provide additional benefit in patients with bipolar II disorder.

Bipolar disorder affects people of all ages, including preschool-aged children. Two major difficulties in diagnosing children with bipolar disorder are its overlap with attention-deficit/hyperactivity disorder (ADHD) and its developmentally distinct presentation from that in adults, with high rates of irritability, chronicity, and mixed states. Comorbid conditions are common in bipolar disorder and, in addition to ADHD, include depression, anxiety disorders, oppositional defiant disorder, and conduct disorder. ⋯ However, using an atypical antipsychotic either alone or in addition to another mood stabilizer has shown utility in treating manic symptoms, depression in mixed states, and aggression. Amphetamine salts have been helpful in treating bipolar children with comorbid ADHD, but no data are available on treating comorbid depression in bipolar children. Because childhood-onset mania is commonly chronic rather than episodic, highly comorbid, and characterized by high rates of irritability, future clinical trials should examine the overlap of mania with other disorders in children to determine routes to accurate diagnosis and treatment.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Efficacy and tolerability of ziprasidone versus risperidone in patients with acute exacerbation of schizophrenia or schizoaffective disorder: an 8-week, double-blind, multicenter trial.
More head-to-head comparisons of antipsychotics are needed to discern the relative efficacy and safety profiles of these compounds. Thus, we compared ziprasidone and risperidone in patients with acute exacerbation of schizophrenia or schizoaffective disorder. ⋯ Both agents equally improved psychotic symptoms, and both were generally well tolerated, with ziprasidone demonstrating a lower MDB score and less effect on prolactin and weight than risperidone.
