Summary

The reversed clock phenomenon, a stroke-induced spatial disorientation, can persist longer than usual. Rehabilitation exercises may help improve this condition and related spatial representation disorders.

Area of Science:

  • Neuroscience
  • Neurology
  • Cognitive Psychology

Background:

  • The reversed clock phenomenon involves spatial disorientation, often seen in clock-drawing tests, and is typically linked to stroke-related attentional network disruption.
  • This neurological condition usually resolves spontaneously within a few days.

Observation:

  • A 67-year-old woman presented with headaches, gait disturbance, visual field deficits, and spatial representation disorders.
  • Magnetic resonance imaging revealed two right cerebral infarcts in the parieto-occipital region.

Findings:

  • The patient exhibited a persistent reversed clock phenomenon, misplacing clock hands and experiencing directional confusion within her home.
  • Despite partial improvement with rehabilitation, the spatial disorientation and clock number reversal did not fully resolve spontaneously.

Implications:

  • This case highlights that the reversed clock phenomenon can have a prolonged course, contrary to its typical short-term manifestation.
  • Targeted rehabilitation, focusing on localization exercises, may offer therapeutic benefits for persistent spatial representation disorders following stroke.
