Organophosphate poisoning
Organophosphate pesticides are one of the top causes of poisoning worldwide, with an annual incidence of poisonings among agricultural workers varying from 3-10% per country.
Organophosphate poisoning
Research has linked the neurological abnormalities found in Persian Gulf War veterans who suffer from chronic multisymptom ilnesses to exposure to wartime combinations of organophosphate chemical nerve agents. Before, it was believed that veterans were suffering from a psychologically based disorder or depression, most likely post-traumatic stress disorder (PTSD). Many veterans were given pyridostigmine bromide (PB) pills to protect against nerve gas agents such as sarin and soman. During the war veterans were exposed to combinations of organophosphate pesticides and nerve agents, which produced symptoms associated with chronic organophosphate-induced delayed polyneuropathy (OPIDP) syndrome. Similar symptoms found in the veterans were the same symptoms reported for individuals in occupational settings who were acutely poisoned by organophosphates, such as chlorpyrifos. Studies found veterans experienced deficits in intellectual and academic abilities, simple motor skills, memory impairment, and impaired emotional function. These symptoms indicate brain damage, not a psychologically based disorder.
