    Overview[edit | edit source]

    Stroke is used to describe pathological conditions caused by brain ischemia or hemorrhage. According to the American Heart Association/American Stroke Association (July, 2013),[1] it is defined as a neurological deficit attributed to an acute focal injury of the central nervous system (CNS) by a vascular cause, including cerebral infarction, intracerebral hemorrhage (ICH), and subarachnoid hemorrhage (SAH). Therefore, by definition, trauma has to be ruled out before stroke can be diagnosed in a patient with a focal neurological deficit.

    Causes[edit | edit source]

    Life Threatening Causes[edit | edit source]

    Life-threatening causes include conditions that may result in death or permanent disability within 24 hours if left untreated.

    • All strokes can potentialy lead to death or permanent disability within 24 hours if left untreated.

    Common Causes[edit | edit source]

    • Aneurysms
    • Atrial fibrillation
    • Eclampsia
    • Infective endocarditis
    • Myocardial infarction
    • Pulmonary embolism
    • Arteriovenous malformations
    • Atherosclerosis
    • Atrial fibrillation
    • Embolism
    • Hypertension
    • Subarachnoid hemorrhage
    • Thrombosis
    • Transient ischemic attack
    • Traumatic brain injury
    • Warfarin

    Diagnosis[edit | edit source]

    Shown below is an algorithm summarizing the diagnosis of stroke according to the American Academy of Neurology guidelines:

    Initial Evaluation[edit | edit source]

     
     
     
    Characterize the symptoms:
    ❑ Sudden weakness/paralysis - face, arm or leg
    ❑ Speech/visual difficulties
    ❑ Altered/loss of consciousness
    ❑ Sudden severe headache
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
     
    Examine the patient:
    Head - trauma, tongue laceration
    Neck - bruits, pulses
    Limbs - pulses
    Heart - murmurs

    ❑ Neurological exam, NIHSS

    Treatment[edit | edit source]

    The management of stroke will greatly depend on the type of stroke (if it is either hemorrhagic or ischemic).

    Do's[edit | edit source]

    Don'ts[edit | edit source]

    • Do not lower blood pressure in hypertensive patients with ischemic stroke when below
