Triphasic waves (TWs) on EEG indicate metabolic disorders like hepatic encephalopathy. This case shows TWs in acute naproxen intoxication, suggesting a link between drug toxicity and these EEG patterns.

Area of Science:

  • Neuroscience
  • Toxicology
  • Biochemistry

Background:

  • Triphasic waves (TWs) are EEG patterns often associated with metabolic encephalopathies, particularly hepatic encephalopathy.
  • Understanding the underlying biochemical mechanisms of TWs is crucial for diagnosing and managing neurological disorders.

Observation:

  • A case of acute encephalopathy secondary to naproxen intoxication is presented.
  • Electroencephalogram (EEG) recordings during this intoxication revealed diffuse, bilateral, and symmetrical TWs.

Findings:

  • The presence of TWs in naproxen-induced acute encephalopathy suggests that this EEG pattern can occur in toxicological conditions beyond typical metabolic disorders.
  • The study discusses potential biochemical pathways that could lead to both the encephalopathy and the observed TWs.

Implications:

  • This finding expands the differential diagnosis for TWs on EEG to include drug-induced toxic encephalopathies.
  • Further research into the neurotoxic mechanisms of naproxen and other drugs may elucidate novel pathways for TW generation.
  • Highlights the importance of EEG in identifying metabolic and toxic derangements affecting brain function.
