Sensory impairment is often regarded from a medical/disability point of view and its effects on mental health can be poorly recognised. Communication is a key issue for deaf and deaf–blind people and difficulties here underlie developmental, psychological and emotional problems and delay or prevent appropriate assessment and treatment. Children may have additional problems associated with the cause of their sensory impairment and need early multi-disciplinary intervention. Emotional and practical support is needed for families to make fully informed choices. Those with and without sensory impairment need the same access to mental health services and this is particularly difficult to achieve for deaf and deaf–blind people. Local and specialist teams need to work together to implement the National Service Framework for this vulnerable patient group.
