Compared with the general population, hearing impairments are more common:
• Approximately 30% have hearing impairment. They can be congenital, or acquired later in life.
• Sensory impairments are much more likely to be unrecognised. Paid carers in particular, under-report sensory impairments.
• Many learning disabilities syndromes have specific associations e.g. sensorineural damage, structural abnormalities of the inner ear.
• Down syndrome, mitochondrial disorders, congenital rubella are especially associated with sensory impairments. Age-related impairments occur earlier in persons with Down syndrome.
• Many can’t self-report age-related hearing impairments.
• Hearing can be assessed even in persons with the most profound learning disabilities.
