Extract

The role of central serotonergic (5-HT) system dysfunction in the regulation of aggression in both animals and man has been investigated for more than the past two decades. Evidence for reduced central 5-HT in the mediation of aggression comes from both behavioural and correlative studies. Functional reduction and augmentation of 5-HT activity is respectively associated with increased and decreased aggression in various animal models of aggression. While similar studies in man have not been performed, strong and consistent associations between indices reflecting reduced pre-synaptic 5-HT activity and aggression have been reported. Evidence of post-synaptic receptor upregulation in the brains of suicide victims has also been reported leaving the functional status 5-HT activity in such patients an open question. However, reduced neuroendocrine (i.e. prolactin) responses to fenfluramine, a 5-HT uptake inhibitor/releaser, which activates both pre- and post-synaptic sides of the 5-HT synapse, strongly suggest that overall central 5-HT activity is reduced in mood and/or personality disorder patients with history of suicidal and/or impulsive aggressive behaviour. Preliminary data with the 5-HT receptor agonist m-chlorophenylpiperazine further suggest that reduced activity of post-synaptic 5-HT receptors may be an important correlate of impulsive aggressive behaviour. Pharmacological agents with potent 5-HT pre- and/or post-synaptic augmenting effects should be tested clinically to determine their efficacy in the treatment of impulsive aggressive behaviour in psychiatric patients.
