<p>Although people with learning disabilities face an increased vulnerability to developing mental health problems, they use relatively few mental health services (Gustafsson 1997). In addition, levels of undetected mental illness are high (Reiss 1993). This has negative consequences for the quality of life for those with learning disabilities and their carers, and for the quality and costs of services provided in community settings.
