METHOD The study was conducted at three adolescent psychiatric departments in two mental health centers in the Tel Aviv area. All patients were Jewish Israelis. Weight and body mass index (BMI) of(More)
Major depressive disorder (MDD) is a severe psychiatric disorder with a lifetime prevalence of about 15%.1 The importance of the genetic component is well accepted,2 but the mode of inheritance is complex and non-Mendelian. A line of evidence suggests the involvement of serotonin and dopamine neurotransmitters in the pathophysiology of depression. In the(More)
Objectives: To evaluate and compare the drug response and side effects of adolescents with schizophrenia treated with olanzapine, risperidone, and haloperidol. Methods: Forty-three patients were treated with olanzapine (n = 19), risperidone (n = 17) and haloperidol (n = 7) for 8 weeks in an open clinical trial.

Some of the psychotropic agents widely used for the amelioration of anxiety, depression, and psychosis also show an effect at the cellular proliferation level. Surprisingly little research, however, has been directed to the antitumoral potential of these drugs, alone or in combination with established cancer treatments. Our review of the literature to date(More)
Obsessive-compulsive disorder (OCD) is a severe and disabling anxiety disorder with a marked genetic contribution. Pharmacological data indicated involvement of the serotonergic and dopaminergic systems. We studied the association between OCD and six candidate genes encoding important components of the serotonergic and dopaminergic pathways in 75(More)
A substantial proportion of schizophrenia patients also has obsessive-compulsive disorder (OCD). To further validate the clinical validity of a schizo-obsessive diagnostic entity, we assessed morbid risks for schizophrenia-spectrum disorders and OC-associated disorders in first-degree relatives of schizophrenia probands with and without OCD. Two groups of(More)
BACKGROUND Since a substantial proportion of schizophrenia patients has symptoms of obsessive-compulsive disorder (OCD), we sought to provide a phenomenological characterization of a schizophrenia subgroup with OCD. METHOD A consecutive sample of patients who met DSM-IV criteria for both schizophrenia and OCD (N = 55) was compared with 55 schizophrenia(More)

METHOD Twenty-four children with an anxiety disorder and their parents participated in a 10-session treatment. Children were evaluated at pretreatment (T1), posttreatment (T2), 12-month follow-up (T3), and 36-month follow-up (T4). Ten children were also(More)
UNLABELLED Preponderance of serotonin 5-HT2A antagonism over dopamine D2 blockade exerted by atypical antipsychotics may contribute to their cognitive-enhancing effect. In a double-blind placebo-controlled study we examined the effect of add-on mianserin (15 mg/day), an agent with marked 5-HT2A antagonism, on cognitive functioning in 30 chronic hospitalized(More)
