Deaf-blindness is a complex disability caused by a combination of hearing and vision loss. There are several potential causes including genetic conditions like Usher Syndrome. The impact on individuals varies depending on factors like age of onset and severity of sensory loss. Assistive technologies and interventions like sign language, Braille, and mobility aids can help deaf-blind people live more independently. Organizations like the Helen Keller National Center provide resources and support to enable deaf-blind individuals to fully participate in their communities.
