Audiological Disorders Prezys
Usher Syndrome
rare genetic
vision (retinitis pigmentosa) & hearing
Types
I: most sever, profound
Hearing & balance loss
II: moderate
Hearing loss
No balance loss
Later vision issues
III: progressive
symptoms show up later
Symptoms treated cuz no cure
Cause less interaction with peers
One of the leading causes of deaf-blindness
Cytomegelovirus
Common DNA virus, but healthy people are asymptomatic
Concern for pregnant people or immunocompromised
Symptoms
Jaunice
Seizure
Difficulty localizing
Audiogram: Bilateral mild to severe hearing loss
Treat and manage symptoms
Risks to speech
No localization, language delays, speech inteligibility
Because of this, doctors perform blood tests at birth
Rubella
Sensorineural hearing loss
Language delays
low birth weight, blue & purple spots, cataracts
When a pregnant women gets rubella during pregnancy which can affect baby. (most severe when in the first trimester)
Meningitis
Kids under age 5
Hearing loss, tinnitus, difficulty hearing in noisy environment, vision troubles, memory issues, brain damage, kidney failure, shock, death
Sensorineural hearing loss
Inflammation of the meninges (membrane around brain & spinal cord)
Hearing loss when the bacteria goes from the meninges to the auditory pathways
The main symptomatic difference between this and cold is a stiff neck
Pretty serious infection
If cochlea has ossified cant do the cochlear implant surgery
Ramsay Hunt Syndrome

Sudden right-sided facial weakness and sever ear pain, facial paralysis, sometimes hearing loss, tinnitus, vertigo, weakness/paralysis on one side of face, dry mouth or eyes, difficulty closing one eye, vesicular rash around one ear
Virus stays dormant until later
Antivirals taken within first 72 hours
Facial paralysis can impact speech production
Hearing loss can impact speech perception
NF2
Rare genetic disorder
Non-cancerous tumors along auditory nerve or on skin
Rare genetic
Bilateral sensorineural hearing loss, mild to severe slope
No cure, can treat symptoms
Multiple tumors
Vestibular schwanoma (acoustic neuroma)

Vestibular therapy for balance
Just one tumor growing on vestibulocochlear nerve
