The ratio of plasma tryptophan to other compet- older children, two studies reported no correlation between ing neutral amino acids was lowest among patients with PRL[D,L-FEN] and aggression (48,49). It is possible that alcoholism with a history of depression or aggression and changes in the 5-HT system occurring over development was lowest among those patients with alcoholism with a affect the nature of the 5-HT–aggression relationship in history of both depression and aggression in two studies that this relationship is positive in some 5-HT–mediated (69,70). Other studies reported elevated levels of plasma pathways, such as the PRL[D,L-FEN] response, in prepuber- tryptophan (or the tryptophan ratio to neutral amino acids) tal children, is absent in postpubertal children, and is inverse in violent offenders (71,72) or positive correlations with in adults. The neurobiological mechanisms underlying this aggression in healthy volunteers (73). Behavioral measures of aggression have been available for many years and include paradigms in which subjects are instructed to deliver a noxious stimulus (e.

In a study of 14 male personality-disor- children and adolescents include the studies of Stoff et al. Another study reported a similar finding with adult subjects, three of four studies reported inverse rela- respect to 5-HT1A receptor function (36). In this study, tionships between platelet 5-HT transporter binding and high PSAP ('high aggressive') responders had blunted ther- aggression or impulsivity in personality-disordered subjects mal responses to ipsapirone challenge compared with low (55,56) and aggressive institutionalized adults (57); the PSAP ('low aggressive') responders. Two studies examined the ducted in research volunteers without documented psycho- function of the platelet 5-HT transporter, with one demon- pathology.

Further analysis revealed, however, that CSF 5-HIAA testosterone and NE (92), and basal testosterone levels have accounted for 80% of the variance in aggression scores.

The Hamilton Depression Rating Scale (HDRS discount 15 mcg mircette fast delivery, or HAM-D (D for depression); Hamilton also created an anxiety scale) has been widely used for more than 5 decades (Hamilton buy mircette 15 mcg overnight delivery, 1960). The HDRS is not used to make a diagnosis, but to rate severity. A diagnosis must be made before the HDRS is applied. Serial ratings over time reflect change (hopefully, improvement). Because it relies on many vegetative symptoms, the HDRS is not applicable when there is a concurrent severe medical disorder. The original HDRS consisted of 21 items, however, shorter versions are available. Even though the HDRS is not used for diagnosis, many researchers have come to equate the 17-item score of 8, and the 6-item score of 4 with remission. To ensure subjects have at least moderate depression, many studies require a 17-item entry score 18. A COPY OF THE HDRS FOLLOWS THE REFERENCES MONTGOMERY ASBERG DEPRESSION RATING SCALE The Montgomery Asberg Depression Rating Scale (MADRS; Montgomery & Asberg 1979) is another important depression scale. It followed almost two decades after the HDRS, but has been widely used over the last quarter of a century. In contrast to the HDRS, the MADRS is less strongly focused on the somatic symptoms of depression, and more strongly on items such as concentration difficulties, tension, lassitude, pessimistic and suicidal thoughts. The initial hope was that being less focused on somatic symptoms, the MADRS would be more sensitive to change than the HDRS. COPIES OF THE HDRS AND MADRS FOLLOW THE REFERENCES Pridmore S.
