    Summary
    This summary is machine-generated.

    This study identified key prognostic factors for acute ischemic stroke patients. Reduced consciousness and gaze paralysis predict poor outcomes, while severe hemiplegia and age impact long-term survival and independence.

    Area of Science:

    • Neurology
    • Clinical Neuroscience
    • Stroke Medicine

    Background:

    • Acute ischemic stroke is a leading cause of death and disability.
    • Identifying prognostic factors is crucial for patient management and resource allocation.

    Purpose of the Study:

    • To examine prognostic factors influencing acute mortality, delayed mortality, and functional independence in patients with acute ischemic stroke of the cerebral hemisphere.

    Main Methods:

    • Prospective study involving 137 patients with acute ischemic stroke.
    • Assessment of neurological status on hospital admission, including level of consciousness and conjugate gaze.
    • Evaluation of functional outcomes (mortality, independence) at various time points post-stroke.

    Main Results:

    Related Experiment Videos

    • Reduced consciousness and paralysis of conjugate gaze were adverse factors for all outcomes.
    • Severe hemiplegia and advanced age predicted worse delayed mortality and disability in survivors, but not acute mortality.
    • Inability to walk, a non-functional hand, and urinary incontinence at three weeks indicated increased risk of death and failure to regain independence.

    Conclusions:

    • Early neurological deficits like reduced consciousness and gaze palsy are critical indicators of prognosis in ischemic stroke.
    • Longer-term outcomes are influenced by factors such as hemiplegia severity, age, and specific functional impairments.
    • These findings correlate with infarct extent, brain swelling, and internal carotid artery occlusion, guiding clinical assessment and treatment strategies.
