The main focus of this learning object is depression amongst older people. The learning object begins by highlighting some of the problems with defining and diagnosing 'depression' and then goes on to discuss the estimated numbers of older people that are thought to suffer from the condition. Issues that make people more or less vulnerable to developing depression in later life are also examined. Finally, effective treatments for depression and explanations for why it so often remains unrecognised in older people is discussed. This object also contains a self-assessment section where you can test how far you have assimilated the key messages from this learning object.
