Attention-deficit/hyperactivity disorder (ADHD) has received an extraordinary amount of attention in the popular media over the past eight months. Stories concerning the disorder, and especially its treatment with stimulant medication, have appeared in many major newspapers, news magazines and television news, entertainment and talk show programs.

Historically, cult refers to a system of worship and more specifically to an innovative religious system, as opposed to a sect, which is a breakaway group from an established religion. During the past 30 years, however, cult has taken on a pejorative connotation arising from disasters such as Jonestown and Waco, and hundreds of media reports of individuals and families devastated by involvement in cults.

Attention-deficit/hyperactivity disorder (ADHD) in adults is a common-and, frequently undiagnosed-psychiatric disorder. This article will focus on the symptoms, associated features, diagnosis, differential diagnosis, prevalence, etiology and treatment of this illness.

Paraphilias as defined by DSM-IV, are sexual impulse disorders characterized by intensely arousing, recurrent sexual fantasies, urges and behaviors (of at least six months' duration) that are considered deviant with respect to cultural norms and that produce clinically significant distress or impairment in social, occupational or other important areas of psychosocial functioning.

Since 1980, criteria for diagnosing bipolar disorder in adults have also been used to diagnose mania in children, with some modifications to adjust for age.

For clinicians, the assiduous and sustained resistance to change common in patients with narcissistic personality disorder (NPD) has been especially noticeable and trying. However, until recently the natural course of NPD has not received much attention in the clinical and empirical literature, and there is very little documented knowledge about the factors that might contribute to changes.

Personality disorders are characterized by the presence of inflexible and maladaptive patterns of perceiving oneself and relating to the environment that result in psychosocial impairment or subjective distress. The enduring nature of the behaviors, their impact on social functioning, the lack of clear boundaries between normality and illness, and the patient's perception of the symptoms as not being foreign make this group of conditions more difficult to conceptualize than the more typical, episodic mental disorders.

Psychopathy (renamed antisocial personality disorder) is marked by persistent violations of social norms, including lying, stealing, truancy, inconsistent work behavior and traffic arrests.

Significant research developments in the etiopathogenesis of schizophrenia have occurred during the past several years. One such advance is the "neurodevelopmental" hypothesis that events during early brain development, especially the prenatal and perinatal periods, may play an important causal role in at least some, and perhaps many, cases of schizophrenia.

Brain serotonin levels as a predictor of suicide has been the subject of intense research scrutiny over the past several years, with scientists trying to find easily accessible markers so that the neurotransmitter's levels might someday be readily measured in clinical settings.

Dopamine plays an important role in controlling movement, emotion and cognition. Dopaminergic dysfunction has been implicated in the pathophysiology of schizophrenia, mood disorders, attention-deficit disorder, Tourette's syndrome, substance dependency, tardive dyskinesia, Parkinson's disease and other disorders.

The gloom of winter, more often a literary theme than a medical topic, is a biological reality for an estimated 10 million Americans who suffer from seasonal affective disorder (SAD). For some, however, the depression ushered in by the dark days of winter can be treated simply and with rapid results with 30 minutes to two hours of bright-light therapy per day for a few weeks.
