Able to produce chemically an adverse effect on the nervous system: such effects may be subdivided into two types.
# Central nervous system effects (including transient effects on mood or performance and pre-senile dementia such as Alzheimer's disease).
# Peripheral nervous system effects (such as the inhibitory effects of organophosphorus compounds on synaptic transmission).
