Digby House provides specialist assessment, treatment and rehabilitation, on a medium to long term basis, for adults with a dual diagnosis of mental disorder and intellectual disability. The Ridley Unit of the BHH is a medium secure facility which provides acute and extended treatment for adults experiencing severe mental illness with associated behavioural disturbances. These people are part of Whishaw Day Centre which provides day programs including a range of supportive and rehabilitive activities. Independent travel on the local bus service to and from the hospital is a daily event. The patients residing in this ward have been long stay residents in the institution.
All patients experience intellectual disability related to a range of pathology such as epilepsy.
