Guide To The Symptoms Of Tay-Sachs Disease

Loss Of Hearing And Vision

As Tay-Sachs disease progresses, a child will almost inevitably experience loss of hearing and vision. The vision loss tends to occur at around ten months, often simultaneously with the appearance of the classic cherry red spot in the eyes. It's likely that children lose their hearing because of damage to their auditory nerves, damage to the sensory processing portion of their brain, or artery blockages caused by other symptoms. The timeline for hearing loss isn't as well-defined as that of vision loss because the auditory symptoms don't progress as methodically. Children tend to become increasingly less responsive from about one year old. Some of this can be attributed to the nervous system degeneration, while some may be caused by hearing loss that keeps them from experiencing sensory stimuli.
