Nervous system and sensory Flashcards
%% of people with hearing loss 65-74 and 75-80
30% and 50%
T/F - communications issues from hearing loss can lead to withdrawal and depression
- people with hearing loss are at greater risk of cognitive decline
- Balance is uneffected by hearing loss
true, True, False - can be effected
Sensorineural hearing loss
inner ear/ auditory nerve damage hearing loss with inability to hear high tones or tolerate loud noises
which is false about sensorineural hearing loss
- occurs with age, injury or disease
- low range is unaffected
- Tinnitus may be the first sign of hearing loss
- is permanent
- low range may be affected eventually
conductive hearing loss
Sound doesn’t reach inner ear due to blockage or punctured ear drum
occupational hearing loss
controllable factors damage ears (environmental noise, excessive noise over time, no protection)
mixed hearing loss
any combination of conductive and sensorineural
Which of the following are associated with hearing loss
- slower walking
- reduced SPPB score
- reduced ADL performance
all
presbyopia
trouble focusing on close objects
cataracts
clouded lens
glaucoma and symptoms
fluid build up puts pressure on optic nerve, leading to poor light adjustment, focus and fogginess
AMD
loss of central vision and light contrast
diabetic retinopathy
changes in the vessels of the eye, may cause blindness

Which of the following is false
