    Summary
    This summary is machine-generated.

    Asterixis, a motor disorder, is typically linked to metabolic issues. This study identifies bilateral extremity asterixis as a new sign of basal ganglia lacunar infarction.

    Area of Science:

    • Neurology
    • Neuroscience
    • Internal Medicine

    Background:

    • Asterixis is a common sign of metabolic encephalopathy.
    • It is infrequently associated with lesions in the thalamus and midbrain.

    Observation:

    • This case report details a patient presenting with bilateral extremity asterixis.
    • The neurological examination revealed this motor disturbance.

    Findings:

    • The patient was diagnosed with basal ganglia lacunar infarction.
    • Bilateral extremity asterixis was identified as a novel manifestation of this specific neurological event.

    Implications:

    • This finding expands the spectrum of clinical presentations associated with basal ganglia lacunar infarction.
  • It suggests that asterixis, beyond metabolic causes, can indicate focal brain lesions in the basal ganglia.
