[Psychotropic drugs and behavior].
Behavioral modifications induced by psychotropic drugs result primarily from their pharmacological properties. According to classification of psychotropic drugs, sedative compounds contrast with psychostimulating medications. Behavioural effects of psychotropic drugs depend on dosing, subject's status (patient or healthy volunteer), acute or chronic administration, and environment. Some psychotropic compounds, particularly sedative drugs, decrease the level of mental alertness and cognitive functioning. But those deleterious effects tend to disappear during the course of a repeated administration. Some psychotropic drugs, especially benzodiazepines, induce a tolerance effect, eventually a psychic or a physiological dependence state evidenced by withdrawal reactions. Such similar dependence processes have been reported with other psychotropic drugs. Forensic problems have been attributed to some psychotropic compounds, like benzodiazepines: paradoxical aggressive reactions, psychomotor automatism. Psychotropic drugs usually can confer a positive effect on behaviour owing to their therapeutic action by the way of improving the illness and consequently the life of patients in the cases of depression, anxiety or schizophrenia.
