Summary
Alien hand syndrome, characterized by involuntary limb movements and a sense of alienness, is rarely reported after acute stroke. This case study details a unique instance following a right parietal infarction, highlighting unusual neurological presentations.
Area of Science:
- Neurology
- Neuroscience
- Clinical Medicine
Background:
- Involuntary movements are uncommon during or after acute stroke.
- Alien hand syndrome (AHS) has not been previously reported following a single parietal infarction.
Observation:
- We present a case of a woman experiencing involuntary movements and a sense of alienness affecting her left upper limb.
- This occurred subsequent to a right parietal infarction.
Findings:
- The patient's presentation met the diagnostic criteria for alien hand syndrome.
- This specific combination of symptoms is rarely observed in cases where the corpus callosum and mesial frontal areas are spared.
Implications:
- This case expands the understanding of alien hand syndrome's potential etiologies.
- It underscores the complex relationship between specific brain lesions and distinct neurological symptoms.
- Further research into the neuroanatomical underpinnings of AHS is warranted.
