Abducens =
VI
Facial -
VII
Vestibulochlear (auditory) =
VIII
Glossopharyngeal =
IX
Vagus =
X
Accessory =
XI
Hypoglossal =
XII
Inability to see faraway objects clearly, also referred to as nearsightedness=
Myopia
Inability to see nearby objects clearly, also referred to as farsightedness
Hyperopia
Defect in the eye making objects nearby look blurry/ distorted
Astigmatism
Age-related farsightedness, or a gradual decrease in the ability to clearly see caused by the loss of flexibility of the lens in the eye =
Presbyopia
Affects blood vessels in the retina causing blindness =
Diabetic Retinopathy
Increase in intraocular pressure due to the buildup of fluid, or aqueous humor, that causes compression of the optic nerve =
Glaucoma
An irreversible degeneration of the macula that leads to a loss of central vision as clients age =
Macular Degeneration
Hearing loss that occurs from problems either in the inner ear or on the vestibulochlear (auditory VIII) nerve =
Sensorineural Hearing Loss
Age-related hearing loss =
Presbycusis
Causing damage to or dysfunction of the cochlear or vestibule =
Ototoxicity
Inability of sound to travel from the outer ear to the eardrum + middle ear =
Conductive Hearing Loss
Inflammation in or the accumulation of fluid in the middle ear that can result in conductive hearing loss =
Otitis Media
Abnormal growth of bone in the middle of the ear =
Otosclerosis
Dynamic interactions between people and their environment using a process that involves cerebration (thinking), cognition, hearing, speech production, and motor coordination
Communication
Act of thinking, or using one’s mind =
Cerebration
Disorder that affects a person’s ability to articulate + understand speech and written language due to brain damage =
Aphasia
Expressive Aphasia =
Frontal lobe damage. Can understand speech but can’t speak the words that they want to say
Comprehensive Aphasia =
Temporal lobe damage. Speaks in long sentences that mean nothing and include unnecessary/ made-up words
Global aphasia =
Multiple areas in the brain. Poor comprehension of language + may be unable to form words
Tactile defensiveness =
Touch = physical pain
Idiopathic Neuropathy =
Unknown cause
Peripheral Neuropathy =
When nerves in the CNS become damaged resulting in numbness, pain, and weakness to the extremities
Taste cells. Sweet, bitter, salty, or savory flavors =
Gustatory Cells
Ageusia =
Inability to taste
Dysgeusia =
Persistent salty, rancid, or metallic taste
Hypogeusia =
Decreased ability to taste
Anosmia =
Inability to smell anything
Used to examine the structures of the eye
Slit lamp
Injection of dye into a peripheral vein, followed by taking photos of the vessels in the eye as the dye flows through them
Fluorescein Angiography
Test used to assess macular degeneration =
Amsler Grid
Helps determine if hearing loss is due to an issue with bone conduction or with the air conduction of sound via the ear canal. Performed with a tuning fork
Rinne Test
Audiometer test = done via the use of-
Earphones
Monitors the response of the auditory nerve to vibrations
Bone oscillator test
Small electrodes are placed on the scalp to measure the brain’s electrical activity in response to clicking noises
Auditory Brainstem Response (ABR) Test
Small probe inserted into auditory canal, sounds are emitted, and the resulting echos is recorded, assessing the response of the inner ear =
Otoacoustic Emissions (OAE) Test
Test for nerve damage. Small needles inserted into a muscle and a machine records the electrical activity in the muscle =
Electromyography (EMG)
Laryngectomy =
Surgical removal of larynx
External device used to produce voice by emitting sounds =
Electrolarynx
Trauma to the outer ear, inflammation, cerumen buildup, and otitis media are all-
Potential causes of conductive hearing loss
