Summary
This summary is machine-generated.

Impaired clock drawing in elderly stroke patients indicates more severe deficits and longer hospital stays. This simple test predicts long-term functional recovery, highlighting its importance in stroke assessment.

Area of Science:

  • Neurology
  • Geriatrics
  • Rehabilitation Medicine

Background:

  • Stroke is a leading cause of long-term disability in the elderly.
  • Assessing cognitive and visuospatial function post-stroke is crucial for predicting recovery.
  • Clock drawing is a simple, widely used screening tool for cognitive impairment.

Purpose of the Study:

  • To investigate the prognostic value of clock drawing in elderly patients following a first-ever stroke.
  • To determine if impaired clock drawing correlates with stroke severity and functional outcomes.

Main Methods:

  • 118 elderly subjects with first-ever stroke were assessed within 14 days.
  • Evaluated tests included clock drawing, pentagon copying, line bisection, Mini-Mental State Examination, and extinction signs.

  • Barthel ADL scores were recorded at multiple time points and at maximal recovery.

    • Main Results:

    • 30 subjects (25%) exhibited impaired clock drawing.
    • Impaired clock drawing was associated with more severe stroke deficits and longer hospitalizations.
    • Patients with impaired clock drawing had significantly lower Barthel ADL scores at all time points and maximal recovery.

    Conclusions:

    • Impaired clock drawing is a significant independent predictor of functional recovery (Barthel ADL) after stroke.
    • This visuospatial and cognitive test can reflect either cognitive impairment or spatial neglect.
    • Clock drawing is a valuable, simple tool for prognostication in elderly stroke survivors.
