1 Available literature dealing with neuropsychopathologi cal changes after exposure to organophosphate insecti cides is reviewed.
2 Subacute neurological sequelae following acute organophosphate intoxication include the 'intermediate syndrome', probably a myopathy elicited by excess acetylcholine, and the 'organophosphate-induced delayed neuropathy' (OPIDN), which is caused by particularly neurotoxic organophosphates that inhibit neuropathy target esterase.
3 Long-term toxic effects affecting behaviour as well as mental and visual functions are occasionally observed after exposure to high doses of organophosphates with repeated acute, clinically significant intoxications.
4 The available data do not indicate that asymptomatic exposure to organophosphates is connected with an increasing risk of delayed or permanent neuro psychopathological effects.
