Study Notes
Ischemic Stroke
- Transient Ischemic Attack (TIA) causes temporary neurologic deficits, including vision changes, speech issues, motor dysfunction, and dizziness, resolving within 24 hours.
- Without diagnosis and treatment, 80% of individuals experience recurrence of symptoms within one year, with many advancing to complete stroke.
Types of Stroke
- Cerebral Thrombosis: Stable plaque leads to narrowing or occlusion, resulting in progressive neurologic dysfunction termed "stroke-in-evolution." Without rapid restoration of perfusion, cerebral infarction leads to a completed stroke.
- Embolic Stroke: Caused by fragments from thrombus outside the brain (heart, aorta), often affecting the middle cerebral artery and leading to occlusion and complete stroke.
Risk Factors for Cardio-embolic Stroke
- Atrial fibrillation, myocardial infarction, and valvular heart disease increase the risk.
- Individuals typically receive anticoagulation therapy (e.g., warfarin) to prevent complications, including stroke.
Clinical Manifestations of Thrombotic Stroke
- Symptoms vary based on the afflicted artery, with common issues arising from middle cerebral artery obstruction including:
- Hemiparesis or hemiplegia (weakness or paralysis on one side)
- Hemisensory loss (diminished sensation on one side)
- Aphasia; potential complications include decreased consciousness, brain herniation, or death due to cerebral edema.
Aphasia and Stroke Recognition
- Aphasia occurs due to brain damage affecting language comprehension and production.
- F.A.S.T. test helps identify stroke symptoms:
- Face: Check for drooping
- Arms: See if one arm drifts down
- Speech: Assess clarity
Intracerebral Hemorrhage
- Characterized by sudden severe headache and vomiting.
- Loss of consciousness and coma may occur; neurologic deficits depend on bleeding extent and location.
- Deterioration of clinical status can happen rapidly despite intervention.
Seizure Disorders
- Involves recurrent abnormal electrical impulses in the brain, categorized into:
- Generalized Seizures: Spread rapidly throughout both hemispheres, causing loss of consciousness.
- Types include tonic-clonic (grand mal), absence (petit mal), and febrile seizures.
- Partial Seizures: Can be simple or complex, localized to one area.
- Generalized Seizures: Spread rapidly throughout both hemispheres, causing loss of consciousness.
Generalized Seizures
- Tonic-clonic seizures include dramatic muscle contractions and postictal confusion.
- Most seizures last 30 seconds to 2 minutes; seizures over five minutes are a medical emergency.
Alzheimer’s Disease
- Characterized by progressive memory loss, particularly for recent events, alongside emotional disturbances.
- Progressive decline in cholinergic neurons leads to further cognitive impairments, including impact on judgment and abstract thinking.
