Lithium treatment for people with learning disability: patients 'and carers' knowledge of hazards and attitudes to treatment

Twenty‐five people with a learning disability who were receiving lithium were assessed with regard to their knowledge of lithium and itsadverse effects, and their attitude to treatment. Questionnaires developed for use by people with mental illness were employed, and information was gathered both from people receiving lithium and their carers. Knowledge of the effects of lithium amongst this group was similar to that found in studies of mentally ill people. There was no significant difference in knowledge according to place of residence (with family, in a community residential facility or in hospital). Most people had a positive altitude to lithium treatment; those with more knowledge had more positive attitudes. People with learning disabilities who are prescribed lithium (and their carers) should receive written information about the effect of the drug. The prescriber should check that sufficient knowledge has been acquired to ensure safety
