47 - Sensory Alterations Flashcards
(31 cards)
Kinesthetic
(position and movement of body parts)
Stereognosis
(recognition of object texture and size)
Reception
Stimulation of receptor nerve cell such as for light, touch, or sound
Perception or awareness
Integration and interpretation of stimuli
Reaction
Usually only the most important stimuli will elicit a reaction
Sensory deficits
Loss in the normal function of sensory reception and perception
Reliance on other senses
May affect behaviour
Age-related macular degeneration (AMD)
loss of central vision
Cataract
cloudy/blur of vision
Diabetic retinopathy
pathological change in eye blood vessles (can leak/go into blindless, leading cause of vision loss of vision in under 50yrs)
Glaucoma
increased pressure in eye that damaged optic nerve
Dry eyes
eldery is prone to dry eyes (so anti-colonergic meds that cause dry eyes can lead to falls)
Refractive errors
most common kind of vision loss, fixed with glasses (myopia, hyperopia, presbyopia )
Retinal detachment
when retnia develops small hole or tears
Conductive hearing loss
sounds waves aren’t effectively transmitted (can be caused by common cold)
Presbycusis
age related hearing loss, can’t hear high pitch sounds, gradual
Central auditory processing disorders
result of damage to auditory centers
Cerumen accumulation
buildup of earwax
Ménière’s disease
inner ear disorder (can have tinnitus, vertigo), generally buildup of fluid in ear
Otitis media
common ear infection
Otosclerosis
hereditary, hardening of ear ossicles, progressive loss
Sensorineural hearing loss – damage to cochlea, hearing nerve or hair cells
Tinnitus
ringing/buzzing in ear
Benign positional vertigo
a problem in the inner ear. It is the most common cause of vertigo, which is a false sensation of spinning or movement.
Xerostomia
lack of salivia (causes lack of food intake)
Peripheral neuropathy
dying nerves in extremites (often due to diabeties)
