Abstract:
In this paper we review neurotoxic disorders appearing in patients poisoned with organophosphorus pesticides. These compounds cause four important neurotoxic effects in humans: the cholinergic syndrome, the intermediate syndrome, organophosphate-induced delayed polyneuropathy (OPIDP) and chronic organophosphate-induced neuropsychiatric disorder (COPIND). Compared to the cholinergic syndrome, that causes millions of cases of poisoning each year, other disorders involve much smaller numbers of patients. The review is focused on the neurotoxic effects appearing after acute and chronic exposure to organophosphates with emphasis on clinical presentation, pathogenesis, molecular mechanisms, and possibilities for prevention/therapy.
Insights
Organophosphorus pesticides can cause several neurotoxic disorders in humans, including the common cholinergic syndrome and less frequent conditions like organophosphate-induced delayed polyneuropathy (OPIDP). This review details their clinical effects, mechanisms, and treatment options.
Area of Science:
- Toxicology
- Neuroscience
- Environmental Health
Background:
- Organophosphorus pesticides are widely used, leading to significant human exposure.
- Pesticide poisoning can result in a range of neurotoxic effects.
- Understanding these effects is crucial for public health and clinical management.
Purpose of the Study:
- To review the neurotoxic disorders associated with organophosphorus pesticide poisoning.
- To emphasize clinical presentation, pathogenesis, and molecular mechanisms.
- To explore prevention and therapy strategies for these conditions.
Main Methods:
- Literature review of neurotoxic disorders from organophosphate exposure.
- Analysis of clinical manifestations and epidemiological data.
- Synthesis of information on pathogenesis and molecular underpinnings.
Main Results:
- Identified four key neurotoxic syndromes: cholinergic syndrome, intermediate syndrome, OPIDP, and COPIND.
- Highlighted the high incidence of cholinergic syndrome versus rarer disorders.
- Detailed the clinical features, mechanisms, and treatment approaches for each syndrome.
Conclusions:
- Organophosphate exposure leads to diverse neurotoxic outcomes.
- Further research into OPIDP and COPIND pathogenesis is warranted.
- Effective prevention and therapeutic strategies are essential for managing organophosphate neurotoxicity.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
