[Peripheral neuropathy and deterioration of the cognitive functions associated to chronic exposure to organophosphates].
OBJECTIVE
To analyze the relationship between the chronic exposure (EC) to organophosphated insecticides (IOF) with the presence of peripheral neuropathy (NP) and the deterioration of cognitive functions (DFC).


METHODS
Cross-section, comparative and observational.


METHODS
Workers with more than three months of seniority, who participated in any stage of the process of production of IOF were included, and those with alterations in the neurological function were excluded. Two control groups were made up: the first one, without direct exposure to IOF, and the second one, without any exposure whatsoever to IOF. A physical examination was practiced on inferior limbs and a motor neuroconduction of the fibular nerves was carried out. The Minimum Exam of the Mental State was set (Mental Mini). The sampling was not random.


RESULTS
It was found that the presence of DFC and the clinical data for NP were greater in the exposed group than in the controls, (p < 0.05). Besides, data with a tendency to the continuation in the parameters of latencies, widths and waves F for the motor neuroconduction of inferior limbs were presented.


CONCLUSIONS
The long term exposure to IOF is related to deterioration in the cognitive function; as well as to the neurological manifestations in inferior limbs that condition an injury in the peripheral nerve, without being conclusive about the loss of its function.
