Psychopathology prevalence

Kleinman (1986) claimed that neurasthenia was a cultural form of chronic somatization that outlined several different types of psychopathological disorders, the major depressive disorder included in western classifications being the one that best accounted for this disorder. This would explain the lower rate of prevalence of the diagnosis of depressive disorder among the Chinese population. 

The prevalence of the Cluster B disorders parallels that of the other personality disorders. Rates range from 1% to 2% of the general population for each of the Cluster B disorders. Despite these rates that parallel the other personality disorder clusters. Cluster B patients command a considerable bulk of our clinical resources. In particular, BPD is the most common of the personality disorders receiving care in most psychiatric settings. The dramatic nature of the Cluster B disorders leads to severely disruptive and erratic behavior that commands clinical attention as opposed to the quiet and unobtrusive psychopathology seen in the Cluster A and Cluster C disorders.

In studies of Vietnam War veterans, the DRD2 TaqlA allele was found to be far more prevalent in combat veterans who developed PTSD (60%) than in those who did not (5%), and is associated with greater psychopathology scores in untreated PTSD patients [71,77]. A similar positive trend is found between DRD2 TaqlA and response to treatment with SSRIs, specifically paroxetine [71].
