Central Auditory Nervous System Sites Potentially Damaged by Blast Exposure
It is also known that, as the disease progresses, there is progressive impairment of the central nervous system, including the central auditory nervous system, either by direct effects of the virus on the central nervous system structures governing the maturational process or as a consequence of opportunist infections [13,15,16].
Other scientists are studying the central auditory nervous system. Cognitive neuroscientists are helping to describe how the processes that mediate sound recognition and comprehension work in both normal and disordered systems.
An older adult may have a hearing loss attributed to natural changes in the auditory system that occur with age (presbycusis), or he or she may have degenerative changes in the central auditory nervous system. Either type of change may affect a person's communicative function.
This fact leads us to consider that each test can activate more or less areas of the central auditory nervous system (CANS) that respond by the physiological mechanism of temporal resolution ability.
Because problems understanding speech in background noise are characteristic of individuals with auditory processing problems and disorders of the central auditory nervous system, one might postulate that individuals with MS would also have this type of deficit.
Behavioral tests and the ABR depend on the status of the central auditory nervous system. OAE's can be rapidly obtained even from sleeping infants and young children.
