Causes and associated conditions
While some rare syndromes cause deafblindness, such as CHARGE and Usher syndrome, many people who are deafblind will have other (often rare) disabilities and health conditions, meaning that diagnosis and the identification of combined sight and hearing loss are difficult.
Many children with profound and multiple learning disabilities will experience limited communication skills and impairments of vision and hearing.
Congenital rubella syndrome is no longer a significant cause of deafblindness, but other infections during pregnancy are a factor, for example cytomegalovirus and toxoplasmosis.
One in ten babies born prematurely will develop a permanent disability such as cerebral palsy, blindness, deafness or lung disease, or a combination of these.
Sensory loss is just one more effect of old age. A hearing and vision loss may have crept up slowly on a person, so they only gradually realise something is wrong. As a result the everyday difficulties a person describes are not just to do with ageing but are the typical effects of deafblindness.
