Prevalence rates range from 0.5% in Eastern samples up to 16% in Western studies. Its prevalence in Israel, an Asian state characterized by Western culture, has not yet been studied. The present study aimed to assess the prevalence of(More)
The worldwide prevalence of obsessive-compulsive disorder (OCD) is approximately 2% of the general population. Symptoms of OCD include fear of contamination by dirt or germs; constant checking; repetitive, intrusive thoughts of a somatic, aggressive, or sexual nature; extreme slowness; and an inordinate concern with orderliness and symmetry. Differential(More)
The outlook for patients with obsessive-compulsive disorder (OCD) began to change in the early 1980s with the introduction of clomipramine (CMI), a serotonergic antidepressant. The observation that only drugs with a serotonergic profile are effective in OCD has been the basis for the serotonergic hypothesis of OCD. The serotonin-selective reuptake(More)
OBJECTIVE The present study aimed to explore the association between stressful life events (LEs) and the development of affective psychopathology. METHOD Thirty patients with unipolar disorder and 30 patients with bipolar disorder were compared to 60 matched healthy controls in regard to the rate of stressful LEs. Assessment measures included the Beck(More)
OBJECTIVE To compare long-term lithium patients who developed renal insufficiency (RI) with those who did not, and to examine what characterized these groups. METHOD One hundred fourteen subjects with DSM-IV bipolar, major depressive, or schizoaffective disorder who had been taking lithium for 4 to 30 years from 1968 to 2000 were studied retrospectively.(More)
The objective of this study was to determine the efficacy of pindolol as an augmentor of fluoxetine in treatment-resistant panic disorder (PD). Twenty-five outpatients having PD with or without agoraphobia were included. These patients had not responded to two different trials with antidepressants and an 8-week trial of fluoxetine 20 mg/day.(More)
