PAPER GRADED A+
◉ Parkinson's disease is associated with.
Answer: basal ganglia dysfunction and atrophy of neurons in the
substantia nigra that produce dopamine;
◉ Characteristics of Parkinson's disease.
Answer: Tremors at rest, rigidity, bradykinesia, muscular rigidity
and postural abnormalities.
◉ 2 Main Categories of CVA.
Answer: Hemorrhagic and Ischemic
◉ Hemorrhagic CVA.
Answer: Blood produces inflammatory reaction, swelling, displaces
brain tissue and increases ICP
◉ 2 types of hemorrhagic stroke.
Answer: Intracerebral and subarachnoid
◉ Intracerebral Hemorrhage.
,Answer: Blood vessel leaks directly into brain tissue
◉ Subarachnoid hemorrhage.
Answer: Bleeding into the subarachnoid space, caused by trauma,
aneurysm rupture presents as "worst headache of life". surgical
emergency
◉ Ischemic CVA.
Answer: reduction in cerebral blood flow results in hypoxia and
irreversible cell death with associated cerebral edema
◉ 3 types of ischemic CVA.
Answer: thrombotic, embolic, hypercoagulable states.
◉ Thrombotic.
Answer: caused by atherosclerosis blocking vessels. obstruction of
blood vessel due to localized occlusive process
◉ Embolic.
Answer: caused by blood clot, fat or air embolus traveling from
distant site to brain
◉ Hypercoaguable state.
, Answer: conditions such as sickle cell disease, polycythemia causing
blood clot to form and obstruct vessel
◉ Multiple sclerosis.
Answer: chronic, inflammatory autoimmune demyelinating disease
of the CNS. : patho includes CNS demyelination thought to be caused
by an immune reaction
◉ Acetylcholine.
Answer: excitatory or inhibitory, enables muscle action, learning,
memory- involved in memory impairment in Alzheimer's disease
◉ Norepinephrine.
Answer: Helps control alertness and arousal. Under supply can
depress mood.
