[Cerebral bioelectric activity disorders in acute intoxication with hypoglycemic agents]

Area of Science:

• Neuroscience
• Toxicology
• Clinical Neurology

Context:

• Presents findings from 10 cases of acute suicidal poisoning involving hypoglycaemic agents.
• Focuses on the electroencephalogram (EEG) changes and neurological outcomes.

Purpose:

• To describe the brain's bioelectric activity disturbances in hypoglycaemic agent poisoning.
• To highlight the long-term neurological consequences and the severity of neuroglycopenia.

Summary:

• Most patients exhibited diffuse, slow EEG activity during hypoglycaemic coma.
• EEG normalization was slow, often taking months, even after short-term hypoglycaemia (1-5 days).
• Prolonged coma led to severe central nervous system damage, including the apallic syndrome.

Impact:

• Emphasizes the profound and persistent neurological damage caused by these poisonings.
• Underscores the urgent need for improved therapeutic strategies to combat neuroglycopenia.
• Informs clinical management and research into managing severe hypoglycaemic agent toxicity.
