Psuedotumor cerebri and insecticide intoxication

G E Sanborn, J B Selhorst, V P Calabrese

    Neurology
    |September 1, 1979

    Summary

    Chronic exposure to the organochlorine insecticide chlordecone (Kepone) was linked to increased intracranial pressure and impaired cerebrospinal fluid absorption in three patients. This suggests a potential neurotoxic effect of chlordecone on brain fluid dynamics.

    Area of Science:

    • Neurotoxicology
    • Environmental Health
    • Neurology

    Background:

    • Organochlorine insecticides, such as chlordecone (Kepone), have been associated with various health concerns.
    • Industrial exposure can lead to chronic intoxication, necessitating investigation into specific health effects.

    Observation:

    • Three patients with headache and elevated intracranial pressure exhibited high levels of chlordecone in blood, serum, and adipose tissue.
    • These individuals were part of a larger group of 23 employees with chronic chlordecone intoxication from occupational exposure.
    • Medical evaluations excluded intracranial masses and other known causes of pseudotumor cerebri.

    Findings:

    • Cerebrospinal fluid (CSF) absorption capacity was assessed in the three patients via subarachnoid infusions.

  • Impaired CSF absorption was identified, even in the presence of minimal papilledema.

    • Implications:

    • This study suggests a potential link between chronic chlordecone exposure and impaired cerebrospinal fluid dynamics.
    • Chlordecone intoxication may contribute to increased intracranial pressure through mechanisms affecting CSF absorption.
    • Further research is warranted to elucidate the neurotoxic mechanisms of chlordecone on the central nervous system.
