what are the cause of partial deafness
Lack of oxygen to the brain causing brain damage, usually during birth.
Cerebral palsy is caused by a damage of certain regions in the developing brain. The damage already could happen in pregnancy or at birth, especially if the child gets not enough oxygen while birth.
Ataxic dysarthria is caused by damage to the cerebellum or its connections to the cerebral cortex or brain-stem.
Diffuse cortical dysfunction refers to a condition where there is generalized impairment or dysfunction in the outer layer (cortex) of the brain. This can result in a variety of symptoms, such as memory problems, cognitive impairment, and changes in behavior or mood. Causes can include conditions like encephalopathy, traumatic brain injury, or certain infections.
Cerebral cortex is the outer layer of the brain. Having a brain that is capable of a variety of brain function "causes" the cerebral cortex!
Disease, toxins, and excessive noise over a duration of time are all causes of hearing loss from damage to the stereocilia in the inner ear. Hearing loss has different degrees, but there is no "form" of deafness. There are multiple reasons a person will become completely deaf, or have some degree of hearing loss. The person can be deaf from birth, or can have progressive hearing loss over their life time.
While there still isn't a definitive cause of Cortical Dysplasia, recent studies have linked it to human papillomavirus.
CADASIL (Cerebral Autosomal Dominant Arteriopathy with Sub-Cortical Infarcts and Leukoencephalopathy) is a rare genetic, degenerative neurological syndrome that causes migraines, strokes and dementia. If you have CADASIL, there is a great support group on Facebook called CADASIL Support! Join us there.
we must wear ear protection when operating loud machinery because of loud voice our eardrum will damage, Once the eardrum will damage it cannot repair itself and causes deafness.
"Cerebral Palsy is caused by damage to brain, which can occur before, after, or during child birth. The cause of the brain damage range from infections, internal bleeding, and also a lack of oxygen. It is therefore recommended you have your Doctor examine your child's medical records, and run neurological scans to determine the cause."
that would be a hereditary thing not a gene mutaion
