Deafness

The two reasons for the inability to hear or deafness in cats is conduction and neurological problems. Conduction anomalies are associated with the structures of the ear. The outer ear is known as the Pinna, then there is the Tympanic membrane which is the eardrum, the ear canal, and the middle ear which is also called the auditory ossicles. Neurological problems can occur in the brain, inner ear, or the auditory nerve. There is unilateral deafness implying that one ear is involved or bilateral deafness involving both ears. [...]

Vision and Hearing problems in senior dogs

Most aging dogs will experience a decrease in both their visual as well as hearing abilities. When this loss occurs slowly, the dog is actually able to adapt and increase his or her dependence on the other senses to balance out the loss of vision or hearing. In this way an elderly dog can easily live a very happy and relatively normal life even with complete hearing or vision loss. Of course there are some modifications that owners need to make, especially with regards to safety issues for these dogs, but there is no need to feel sorry for your dog or believe that they feel the loss of these senses the same way that humans would.

Neurological Inherited Conditions

Neurological conditions are those conditions that affect the central nervous system or the functioning of the muscles in relation to nerve impulses. Many of the conditions that can occur in dogs also occur in humans as well as other animals, which means there is considerable research and information available on these conditions. Just as with humans, there are medications that can be used to treat some of the neurological conditions, such as epilepsy, but others are progressively degenerative and usually result in death in a relatively short period of time. This is largely due to the brain's control over all the body processes including breathing, circulation and movement. When any or all of these systems become dysfunctional there is a greater risk to the dog to develop other related health problems that tend to make successful treatment and full recovery much more challenging.
