Mayo Clinic Minute: What is hearing loss?
Medical
professional
s may perform a number of tests to diagnose hearing loss. Among the diagnostic procedures the mayo clinic lists are the following:.
Signs and symptoms [ edit ]
Hereditary/genetic factors
genetic factors (hereditary) cause more than 50% of all hearing loss in children. It can be present at birth or develop later in life. Most genetic hearing loss can be described as autosomal recessive or autosomal dominant. In easy words, hearing loss may be inherited from one or both parents. This type of inheritance pattern accounts for about 70% of all genetic hearing loss. Genetic syndromes have a group of signs and symptoms that together indicate a specific disease:
down syndrome
complications associated with the rh factor in the blood. Toxins (alcohol or drug) consumed by the mother during pregnancy.
Causes [ edit ]
The most common causes of hearing loss are ageing and exposure to excessive noise. Some other risk factors include: trauma to the head or ear autoimmune conditions — such as rheumatoid arthritis and autoimmune inner ear disease hereditary conditions — including alport syndrome, a genetic condition associated with hearing loss.
Meaning ‘born with’, the term ‘congenital hearing loss’ is used when a hearing loss has been present since birth. This can occur in one of two ways: the hearing was damaged during fetal development or complications during birth itself; or certain genes inherited by the baby resulted in a hereditary loss of hearing function at some point in their life (it is not always present from birth). Examples of non-genetic causes of congenital hearing loss include: maternal rubella, syphilis or certain other infections during pregnancy low birth weight a lack of oxygen at birth use of certain powerful drugs during pregnancy as treatment for life-threatening infections or diseases.
Commentary: in ukut 252 (aac) , the upper tribunal found that, where a person has to remove their hearing aids in order to have a bath or shower and that means they cannot hear or identify a typical alarm, then they should score 2 points under activity 4 - washing and bathing - either for needing an applicance such as a flashing light in the bathroom, or for supervision so that another person can ensure they are safe. Judge perez also found that the assessment of risk was not subjective and that first-tier tribunals should not be able to make different decisions in this respect.
Sensorineural hearing loss encompasses disorders that affect the inner ear and the neural pathways to the auditory cortex. Although most patients with this type of hearing loss are adults, children also can be affected. Hereditary and non-hereditary congenital hearing loss are the two major pediatric classifications. The majority of hereditary losses are autosomal recessive and are frequently associated with other systemic findings. More than 100 congenital syndromes are associated with sensorineural hearing loss. The consequences of delayed detection can be significant. Neonates considered at high risk for congenital hearing loss ( table 3 ) 11 traditionally have been screened, and 30 states now require universal newborn auditory screening.
