    Area of Science:

    • Neurology
    • Neuropsychology
    • Gerontology

    Background:

    • Acute stroke survivors often experience cognitive impairment.
    • Understanding factors influencing post-stroke cognitive decline is crucial for patient management.
    • Depressive symptoms can co-occur with and potentially impact cognitive function after stroke.

    Purpose of the Study:

    • To assess cognitive ability in six-month survivors of acute stroke.
    • To identify factors associated with cognitive impairment at six months post-stroke.
    • To explore the relationship between cognitive changes, depressive symptoms, and stroke characteristics.

    Main Methods:

    • A consecutive series of 189 six-month stroke survivors were assessed for cognitive ability.
    • Cognitive function was evaluated at one and six months post-stroke.

    Related Experiment Videos

  • Factors including age, stroke severity, and hemisphere of damage were analyzed in relation to cognitive outcomes.

    • Main Results:

    • Twenty-two patients (11.6%) exhibited cognitive impairment at six months.
    • Age and stroke severity were strongly associated with six-month cognitive impairment.
    • Left hemisphere damage correlated with impaired short-term recall; bilateral signs indicated the highest risk.
    • Among 10 patients with cognitive deterioration, four had significant depressive symptoms.

    Conclusions:

    • Cognitive impairment is a significant issue for stroke survivors.
    • Age and stroke severity are primary predictors of cognitive impairment.
    • Left hemisphere damage and bilateral signs increase the risk of cognitive deficits.
    • Post-stroke cognitive impairment warrants assessment for depression, as treatment may be beneficial.
