Sensory Alterations Flashcards
sensory processing disorder (SPD)
difficult interpreting and responding to stimuli; discovered during childhood - more often in autism, ADHD, OCD
myopia
nearsightedness (can’t see far)
hyperopia
farsightedness (can’t see near)
presbyopia
age-related farsightedness; loss of flexibility of the lens
diabetic retinopathy
damage to the blood vessels of the retina leading to vision loss in adulthood
glaucoma
increase in intraocular pressure from build up of fluid (aqueous humor) that compresses the optic nerve; irreversible but can be slowed; start with peripheral vision loss
macular degeneration
loss of central vision with age
tinnitus
hearing sound when no external sound is present
sensorineural hearing loss (SNHL)
inner ear or vestibulocochlear nerve issue from genetics or infection; most prevalent
presbycusis
loss of hearing with age usually over 75yrs old
conductive hearing loss
sound can’t travel from outer ear to the eardrum and middle ear
otis media
inflammation or accumulation of fluid in the middle ear leading to conductive hearing loss
otosclerosis
abnormal growth of bone in the middle ear
aphasia
can’t articulate, understand speech and written language; brain damage
expressive aphasia
damage to frontal lobe; understand but can’t speak the word they want to say
comprehensive aphasia
damage to temporal lobe; long sentences that have no meaning and often has unnecessary or made up words; can’t understand what’s said and can’t comprehend others don’t understand what theyre saying
global aphasia
poor comprehension and can’t form words or sentences
tactile defensiveness
physical pain with nonpainful tactile stimuli
idiopathic neuropathy
nerve damage from unknown cause
gustatory cells
taste cells
phantom taste perception
foul taste when mouth is empty
hypogeusia
decreased ability to taste
ageusia
inability to taste anything at all
dysgeusia
persistent salty, rancid, or metallic taste
anosmia
inability to smell
hyposmia
reduced ability to smell
parosmia
alteration in smell
phantosmia
nonexistent smell is perceived
what senses are affected by NSAIDs
hearing and taste
what senses are affected by antibiotics
hearing, taste, smell
what senses are affected by loop diuretics
hearing
what senses are affected by antihypertensives
taste
what senses are affected by psychotropics
taste
what senses are affected by antihistamines
hearing, taste, smell, vision
what senses are affected by aspirin
hearing
fluorescein angiography
dye injected into peripheral vein; photos taken while dye flows through the eye
diagnostic test for macular degeneration; what to look for
amsler grid: if grid looks wavy or any parts missing; look for drusen (yellowish deposits of protein and lipids under the retina; fluorescein angiography
rinne test
hearing loss from bone conduction or air conduction; tuning fork test against mastoid bone
audiometer test
sound in each ear and see if can identify
bone oscillator test
effectiveness of vibrations through the ossicles
auditory brainstem response (ABR) test or brain audioevoked response (BAER) test
brain’s response to sound; electrodes on scalp to measure brain’s electrical activity
otoacoustic emissions (OAE) test
response of the inner ear to sound waves; probe in ear, should have return echo
electromyography (EMG) test
damage to the nerves leading to the muscle; use needles that records electrical activity in the muscle
electrolarynx
artificial larynx
