Four experiments were conducted to determine the effect of parachlorophenylalanine (PCPA) on the male mating behavior of a line of chickens genetically selected for low mating frequency and to determine the effect on brain concentrations of 5-hydroxytryptamine, dopamine (DA) and norepinephrine (NE). Mating behavior was not affected by moderate levels (less than 64 mg/kg) of PCPA, and decreased significantly when higher levels (100 mg/kg) of the drugs were administered. Results suggest that elevated brain serotonin titers were not causing the low mating frequency associated with the selected line. Birds receiving higher levels of PCPA exhibited a lethargy which persisted for approximately ten days after withdrawal of the drug. Serotonin, DA, and NE were all significantly reduced in the brains of birds receiving PCPA (30 mg/kg).

Aripiprazole is an atypical antipsychotic medication that is a partial dopamine D(2) and serotonin 5-hydroxytryptamine (1A) receptor agonist and 5-hydroxytryptamine (2A) receptor antagonist. It has a safer profile compared to other antipsychotic medications with regard to its effect on weight, glucose tolerance, prolactin level, and cardiac conduction. The common neurological adverse effects include headache, agitation, insomnia, sleepiness, and extrapyramidal symptoms. Seizures have not been reported in the pediatric population and only twice in adult patients. Here, we report a case of a healthy 3-year-old child who experienced prolonged lethargy, dystonia, and 2 witnessed seizures after incidental ingestion of 30 mg of aripiprazole. To our knowledge, this is the first reported case of aripiprazole-induced seizures in a child.
