Chapter 10 Flashcards
Epilepsy
Chronic brain disorder characterized by recurrent seizure activity.
Huntington’s disease
Hereditary disorder marked by degenerative changes in the cerebrum leading to abrupt involuntary movements and mental deterioration.
Multiple sclerosis (MS)
Destruction of the myelin sheath on neurons in the CNS and its replacement by plaques of sclerotic (hard) tissue.
Palsy
Paralysis (partial or complete loss of motor function). Cerebral palsy is partial paralysis and lack of muscular coordination caused by loss of oxygen (hypoxia) or blood flow to the cerebrum during pregnancy or in the perinatal period.
Bell palsy
paralysis on one side of the face. The likely cause is a viral infection
Parkinson’s disease
Degeneration of neurons in the basal ganglia, occurring in later life and leading to tremors, weakness of muscles, and slowness of movement.
Tourette’s
Involuntary spasmodic, twitching movements; uncontrollable vocal sounds; and inappropriate words.
herpes zoster (shingles)
Viral infection affecting peripheral nerves.
Meningitis
Inflammation of the meninges; leptomeningitis. This condition can be caused by bacteria (pyogenic meningitis) or viruses
human immunodeficiency virus (HIV)
Brain disease and dementia occurring with AIDS.
cerebral contusion
Bruising of brain tissue resulting from direct trauma to the head.
cerebrovascular accident (CVA)
Disruption in the normal blood supply to the brain; stroke.
Thrombotic stroke
blood clot (thrombus) in the arteries leading to the brain, resulting in occlusion
Embolic stroke
an embolus (a dislodged thrombus) travels to cerebral arteries and occludes a vessel. This type of stroke occurs very suddenly.
Hemorrhagic stroke
a cerebral artery breaks and bleeding occurs. This type of stroke can be fatal and results from advancing age, atherosclerosis, or high blood pressure
Major risk factors for strokes
The major risk factors for stroke are hypertension, diabetes, smoking, and heart disease.
Tissue plasminogen activator (tPA)
Surgical intervention with carotid endarterectomy (removal of the atherosclerotic plaque along with the inner lining of the affected carotid artery) also is possible.
cerebrospinal fluid analysis
Samples of CSF are examined. CSF analysis measures protein, glucose, and red (RBC) and white (WBC) blood cells as well as other chemical contents of the CSF.
cerebral angiography
X-ray imaging of the arterial blood vessels in the brain after injection of contrast material.
computed tomography (CT) of the brain
Computerized x-ray technique that generates multiple images of the brain and spinal cord.
electroencephalography (EEG)
Recording of the electrical activity of the brain.
lumbar puncture (LP)
CSF is withdrawn from between two lumbar vertebrae for analysis
LOC
Level of consciousness
ICP
Intracranial Pressure
DTR
Deep tendon Reflex
Rombergs test
Tests for cerebellar function (balance)
