Aging and homicide rates.

There are no published studies concerning the effect of mortality rate on the rate of homicide by habitually violent offenders. On the basis of nation-wide statistics in Finland, the frequency of homicide is 61% lower among 50-year old males than among 30-year old males. However, when the 4.

Mortality among habitually violent offenders.

There are no published studies about mortality among habitually violent offenders, although it would be essential to take into account the possibly higher mortality rate of this population, when the incidence of committing violent offenders is calculated as a function of age. We studied mortality during the age range 30-50 years among 102 habitually violent male offenders, who were considered to be dangerous to the lives of other people, during the 24.5-year period 1971-1995 (in the range 3.

Serum testosterone levels, mental disorders and criminal behaviour.

Objective: Although previous studies have revealed an association between androgens and aggression, there is a lack of knowledge of this issue in different mental disorders.

Method: The associations between serum testosterone levels and criminal behaviour in different mental disorders were examined using data collected from forensic psychiatric male patients (20 schizophrenics and 42 subjects with personality disorders).

Results: Male criminals with personality disorders had significantly higher serum levels of total and free testosterone than criminal schizophrenics.

Acute ethanol-induced changes in cerebral blood flow.

Using high-resolution single photon emission computed tomography, the authors studied changes in cerebral blood flow (CBF) in six healthy men after the men rapidly consumed intoxicating amounts of ethanol. When the subjects were given intravenous placebo before ethanol intake, regional CBF was significantly increased over baseline in the right prefrontal cortex, but no significant change in CBF was observed when the subjects received intravenous naloxone before ethanol intake. The results indicate that euphoria occurring during acute ethanol intake is associated with activation of the right prefrontal cortex and mediated through the endogenous opioid system.
