  - subdivides
    - thrombotic strokes
      - caused by
        a blood clot that develops in the blood vessels inside the brain.
      - who affects?
        older people usually with cholesterol or diabetes
      - symptoms
        can occur suddenly
        can be gradual
        stroke-in-evolution
      - may be preceded by "mini-strokes"

      - another type is
        lacunar infarct
    - embolic strokes
      - caused by
        a blood clot or plaque debris that develops elsewhere in the body and then travels to 1 of the blood vessels in the brain via the bloodstream
      - usually result of

        atrial fibrillation
      - can occur rapidly and without warnings

  - CAUSED BY
    - bleeding
  - subdivides
    - intracerebral hemorrhage
      - where is the bleeding?
        Bleeding is from the blood vessels within the brain
      - caused by
        hypertension
      - can cause

        coma
      - how does it occur?

    - subarachnoid hemorrhage
      - where is the bleeding?
        Bleeding is in the subarachnoid space
        between the brain and the meninge
      - normally caused by
        arteriovenous malformation (AVM).
        consists of
        disorderly tangled web of arteries and veins
        is
        congenital
        aneurysm
        is
        weakened, ballooned area on an artery wall and has a risk for rupturing.
        can be
        congenital
        develop later
it ca be produced
- left side brain
  - it will affect the right side of the body
    - besides
      - aphasia
        types
        fluent aphasia
        Wenicke's aphasia
        may speak in long, complete sentences that have no meaning, adding unnecessary words and even creating made-up words.
        Language comprehension impaired
        Transcortical Sensory Aphasia
        repetition of words/phrases good

        Anomic Aphasia
        repetition of words/phrases good
        word finding difficulties
        uses generic fillers (e.g., “thing”) or circumlocution
        non-fluent aphasia

        Broca's aphhasia
        may understand speech and know what they want to say, but they frequently speak in short phrases that are produced with great effort.
        Transcortical Motor Aphasia
        strong repetition skills
        may have difficulty spontaneously answering questions
        Language comprehension impaired
        Global Aphasia
        evere expressive and receptive language impairment
        may be able to communicate using facial expression, intonation, and gestures
        exceptional aphasias
        Crossed aphasia
        subcortical aphasia
        Primary progressive aphasia (PPA)
        type of dementia
      - apraxia
      - Slow, cautious behaviors
      - memory loss
- brain stem
  - can
    - affect both parts
    - leave someone "locked-in"
    - cause ataxia
      - body’s inability to coordinate how muscles move together
- right side brain
  - it will affect the left side of the body
