CH 22: Neurologic Function Flashcards

1
Q

effects of aging on the neurological system

A
  • Nerve cell declines, demyelination of cells, fewer dendrites _ slow nerve conduction _ slow responses and reactions
  • Plaques, tangles, and atrophy occur in the brain
  • Decreased cerebral blood flow _ increased risk for strokes
  • Ability for the brain to compensate after an injury decreases
  • Slowing in central processing _ delays in time required to perform tasks
  • Gradual reduction in vocabulary; difficulty learning; forgetfullness
  • Number and sensitivity of sensory receptors, dermatomes, and neurons decrease _ dulling of tactile sensation
  • Decline in cranial nerves for taste and smell
  • Decreased kinesthetic lens _ slower response to changes in balance _ falls

Q

Treatment for Parkinson’s in older adults

A

meant to minimize the disability
carbidopa/levodopa - increase dopamine
dopaminergics - increase dopamine
anticholinergics (but be careful) - decrease acetylcholine
avoid vit B6 when on levodopa
(counteracts med; avocado, lentils, lima beans)***SATA
deep brain stimulation
there is NO cure

A

ROM
warm baths and massage - rigidity
