Summary
This narrative review synthesises the published evidence linking exposure to common pesticide classes — including carbamates, organophosphates, and pyrethroids — to a range of central nervous system disorders and neurodegenerative conditions. The authors examine both acute neurological effects and long-term outcomes, including cognitive impairment and developmental delays in children, with particular attention to Parkinson's and Alzheimer's disease. Proposed mechanisms centre on pesticide-induced oxidative stress and disruption of neurotransmission pathways in non-target organisms, including humans.
UK applicability
The findings are broadly applicable to UK conditions, where organophosphates and pyrethroids remain in agricultural and domestic use under regulated frameworks; the review's evidence base informs ongoing UK policy debates around pesticide authorisation, occupational exposure limits, and public health protections under post-Brexit regulatory arrangements.
Key measures
Incidence and risk of CNS disorders associated with pesticide exposure; mechanistic markers including oxidative stress indicators and neurotransmission disruption; developmental outcomes in children; association with Parkinson's and Alzheimer's disease
Outcomes reported
The review reports on the neurological effects of pesticide exposure in humans, including acute symptoms and chronic neurodegenerative outcomes such as Parkinson's and Alzheimer's disease. It also examines proposed biological mechanisms, including oxidative stress induction and disruption of neurotransmitter systems.
