Deafblindness is a combination of sight and hearing loss that affects a person's ability to communicate, access information and get around.
It's also sometimes called "dual sensory loss" or "multi-sensory impairment".
A deafblind person won't usually be totally deaf and totally blind, but both senses will be reduced enough to cause significant difficulties in everyday life.
Deafblindness most commonly affects older adults, although it can affect people of all ages, including babies and young children.
