A stroke patient experienced visual-spatial neglect and construction disorder, affecting his ability to perceive and replicate the left side of visual information. This case highlights the intricate link between cerebral infarction and spatial processing deficits.

Area of Science:

  • Neuroscience
  • Neurology
  • Cognitive Psychology

Background:

  • Cerebral infarction can lead to diverse neurological deficits.
  • Visual-spatial neglect and constructive disorder are significant cognitive impairments following brain injury.

Observation:

  • A 61-year-old male patient with right cerebral infarction presented with pronounced visual-spatial neglect.
  • The patient demonstrated difficulties in copying geometric designs, line bisection, and recalling memorized images, consistently omitting or misplacing elements on the left side.
  • Specific deficits included ignoring left-sided figures in drawings and misjudging line centers.

Findings:

  • The observed symptoms strongly correlate right cerebral infarction with left-sided visual-spatial neglect.
  • Constructional disorder, characterized by difficulties in drawing and spatial organization, was evident.

  • The patient's performance on tasks like the Rey Complex figure test further confirmed spatial processing deficits.

    • Implications:

    • This case underscores the critical role of the right cerebral hemisphere in spatial awareness and visual processing.
    • Understanding these deficits is crucial for accurate diagnosis and targeted rehabilitation strategies for stroke survivors.
    • Further research can elucidate the neural mechanisms underlying neglect and constructional disorders in unilateral brain damage.
