Summary
This summary is machine-generated.

Stroke patients often experience time perception dysfunction, commonly underestimating short durations. Lesions in the right hemisphere, particularly the thalamus and parietal cortex, are frequently associated with these neurocognitive changes.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Neurology

Background:

  • Time perception, the subjective experience of time's passage and event duration, is altered in various neurological and psychiatric conditions.
  • Specific details on time perception deficits following stroke are limited, necessitating further investigation into this neurocognitive change.
  • This study aims to systematically review and describe time perception dysfunction in stroke patients.

Approach:

  • A systematic literature review was conducted across PubMed, PsycInfo, and EMBASE databases, including studies from inception until December 2020.
  • Data extracted included the type of time perception affected, stroke type, lesion location, evaluation methods, and timing of assessment post-stroke.
  • Twenty-seven studies involving 418 stroke patients were analyzed.

Key Points:

  • The most frequent deficit observed was underestimation of sub- and supra-second durations (41.7%).
  • Overestimation of time (27.8%) and impaired time interval comparison (22.2%) were also significant findings.
  • Right hemisphere lesions (52.4%) were most common, with frequent involvement of the thalamus, insula, basal ganglia, prefrontal cortex, parietal cortex, and cerebellum.

Conclusions:

  • Time perception dysfunction after stroke is linked to diverse brain lesion locations, underscoring the complexity of the underlying neural systems.
  • Current knowledge regarding specific post-stroke time perception deficits remains scarce.
  • Further research is needed to translate psychometric findings into clear clinical and functional implications for daily activities.
