Summary
This summary is machine-generated.

Alien hand syndrome (AHS) is two distinct conditions: frontal AHS and callosal AHS. Each has unique causes, symptoms, and brain damage locations, differentiating them clinically.

Area of Science:

  • Neuroscience
  • Neurology

Background:

  • Alien hand syndrome (AHS) is a rare neurological disorder.
  • Previous research has not clearly distinguished subtypes of AHS.

Observation:

  • This review examined 20 reported cases of AHS and one new patient.
  • Clinical characteristics and neuroanatomical data were analyzed.

Findings:

  • AHS comprises two distinct syndromes: frontal AHS and callosal AHS.
  • Frontal AHS involves the dominant hand, compulsive actions, and damage to medial frontal/supplementary motor areas and anterior corpus callosum.
  • Callosal AHS presents with intermanual conflict, linked to anterior callosal lesions.

Implications:

  • Understanding these subtypes aids in accurate diagnosis and targeted treatment of AHS.
  • Neuroanatomical distinctions provide insights into motor control and hemispheric interactions.
