Study Notes
- Seizures: two main types - Generalized and Partial
- Generalized Seizures: affects most or entire brain, e.g. tonic-clonic (convulsion) seizures
- Tonic-clonic seizures: involves both tonic (muscle contraction) and clonic (jerking movements) phases
- Absence seizures: loss of consciousness but able to speak during
- Status Epilepticus: non-stop seizure, high mortality, only treatable with powerful drugs
- Strokes: accidents in brain's vasculature, two types - hemorrhagic and obstructive
- Hemorrhagic Strokes: rupture in blood vessels, cause: weak blood vessels, extreme angles, high blood pressure, diabetes
- Diabetes: blood sugar disorder, high blood sugar damages peripheral vasculature, risk of ischemic stroke due to damage to small blood vessels
- Obstructive Strokes: clot blocks brain's blood vessel, causes: high blood pressure, smoking, inactivity, sedentary lifestyle, obesity, diabetes
- Stroke symptoms: face droop (hemiplegia), difficulty speaking, holding arms out and dropping, difficulty understanding language
- Stroke treatments: hemorrhagic strokes treated with clotting drugs, obstructive strokes with blood thinners, risk of worsening condition if treatments are mixed up
- Risk factors for hemorrhagic strokes: born with weak blood vessels, extreme angles, high blood pressure, diabetes
- Risk factors for obstructive strokes: high blood pressure, smoking, inactivity, sedentary lifestyle, obesity, diabetes
- Stroke anatomy and symptomatology: ischemia (tissue death due to blood deprivation), thrombus (clot) formation, obstructive embolus (clot chunk traveling along vasculature), symptoms include lateralizing (hemiplegia), difficulty speaking, arm dropping.
- Stroke treatments: hemorrhagic strokes treated with clotting drugs, obstructive strokes with blood thinners, risk of worsening condition if treatments are mixed up.
