Loneliness: the present and the future.

An enquiry into loneliness and social isolation should be an integral part of the comprehensive geriatric assessment. Loneliness can have negative effects on the psychological and physical health of an older adult. The presence of loneliness is associated with cognitive impairment, decreased mobility and increased difficulties with activities of daily living. Charitable campaigns, such as the Campaign to End Loneliness, are raising the awareness of this important issue. The perception of loneliness can be altered, with social and psychological interventions holding an important role in improving an individuals' perception of loneliness. Voluntary sector initiatives are providing promising solutions to combat loneliness but closer collaboration between voluntary organisations and community services is required. In order to influence the existing strategy and public policy, further studies are required to assess the effectiveness of interventions aimed at improving the harms that arise from loneliness.
