Q

Health Assessment Interview

consider what-

interview-questions?

what testing

A

Consider genetic influences-many neurologic diseases have a genetic component due to inheritance of a gene or gene mutation,

Interview- questions to ask?— ask about family history, health problems related to neurological disorders, history of disorders like- seizures, ALS,MS, Parkinson, tremors, past history of dizziness, headaches, trauma, or injury

Genetic testing, counseling if data collected indicates risk factors or alterations

Dosing-need to take exact dose

Not always well tolerated-ca cause decreased alertness, headache, dizziness,

Frequent blood monitoring-make sure they have decreased blood levels, need to do liver function test

89
Q

Multiple Sclerosis- patho

response
destroyed
slows/distorts

A

autoimmune response,

the myeline sheath that protects nerve fibers are destroyed,

demyelination slows and distorts impulse transmission

Sensory loss, visual deficits, weakness, paresthesia, ataxia, vertigo

91
Q

Multiple sclerosis

exacerbations
remission
end result

A

Exacerbations- manifestations present,

remission- manifestations not obvious

end result- total loss of function
