Biochemistry and Neuropharmacology of obsessive compulsive disorder(OCD)

Biochemistry and Neuropharmacology of obsessive compulsive disorder(OCD) Although they are an indirect assessment of brain function, data from biochemical challenge studies and pharmacological treatment outcome studies suggest that the orbital and cingulate cortex may be potential neuroanatomical sites of dysfunction in OCD. Data that address the neurochemistry of OCD have been collected under three conditions: […]

Biological Contributions to obsessive compulsive disorder (OCD)

Biological Contributions to obsessive compulsive disorder (OCD) In 1985, Turner, Beidel, and Nathan reviewed the available data that addressed biological factors in obsessive compulsive disorder (OCD). Included in the review were genetic and family studies, neurophysiological and neuropsychological studies, neuroanatomical studies, and biochemical and pharmacological studies. Turner et al. concluded that although biological factors correlated […]

obsessive compulsive disorder epidemiology

obsessive compulsive disorder (OCD) Epidemiology The now well-known Epidemiological Catchment Area (ECA) survey conducted during the early 1980s indicated lifetime prevalence rates for OCD of 1.9 to 3.3% in five U.S. communities and an overall rate of 2.5%. These rates were much higher than any previous estimates and were conf irmed by similar epidemiological, albeit […]

Preparedness of specific phobias

Many objects that are in the subject’s immediate environment when traumatic events occur do not acquire fearful properties. Subsequently, phobias are usually found in response to a limited set of all of the possible cues in the world. Observations such as these led Seligman to propose that certain stimuli are biologically ‘‘prepared’’ to become associated […]

Genetic and Familial Factors of specific phobias

Genetic and Familial Factors First-degree relatives of people with specific phobias are more likely themselves to have a specific phobia providing evidence for the importance of either genetic or environmental family factors in the disorder. More specifically, a few twin studies demonstrated a genetic involvement in specific phobias but the importance of environmental factors was […]

Somatic Symptoms of specific phobias

Somatic Symptoms When specific phobics are not confronting their feared object, they experience the least severe and debilitating anxiety disorder, generally demonstrating relatively normal levels of trait anxiety. Such subjective reports are supported by physiological assessment, which also demonstrates that specific phobics in chronic arousal are not different from normal controls. When confronting their feared […]

specific phobias Clinical Features: Epidemiology

specific phobias Clinical Features: Epidemiology Mild fears of specific objects or situations are extremely common in the general population. Fears that are considered clinically severe are still relatively common compared to the other anxiety disorders. The National Comorbidity survey found a lifetime prevalence for specific phobias of approximately 11% in adults and the 6-month prevalence […]

social phobia gene treatment

Although a considerable literature suggests that beta-blockers are effective in reducing performance anxiety that is related to social anxiety, these results have generally been observed in subjects without extreme levels of performance anxiety. Furthermore, any significant results are confined to performance involving motor activity, which suggests that beta-blockers may work mainly for nonclinical subjects by […]

Social Phobia Treatment Psychological Techniques

A number of studies demonstrated the value of cognitive behavioral treatment packages for reducing social phobia, compared with wait list and with a credible placebo treatment. In addition, follow-up assessment indicated that in most studies continued improvement is seen following the end of treatment. In terms of specific techniques, in vivo exposure is generally considered […]

Biological factors of social phobia

Research into central biochemical factors associated with social phobia has not been as extensive as that for panic disorder, and many studies provided mixed findings. The most consistent results implicated serotonin in the pathogenesis of social phobia. The most obvious evidence came from treatment with serotoninreducing agents. However, because many of these drugs also affect […]
