Depression is a common disorder in old age, affecting at least 10% of
individuals over 65. In older people, the relationship between depress
ion and impaired social functioning and quality of life is complex and
ill defined. Despite well-tolerated and effective treatments, many de
pressed individuals are undiagnosed or under-treated. The impact of de
pression on the quality of life (QOL) and social functioning of older
people can be considerable. Furthermore, impairment of social function
ing, consequent on the social isolation and functional disability that
goes hand-in-hand with ageing, may be a causative factor in old age d
epression. Once depression develops, it may result in further narrowin
g of social repertoire, compounding the problem. Notwithstanding some
of the difficulties in measuring social functioning and quality of lif
e, progress has been made in defining the extent of these problems in
older depressed individuals. The impact treatment of depression has on
these parameters is becoming increasingly recognised and evaluated in
clinical trials. Int Clin Psychopharmacol 13 (suppl 5):S19-S24 (C) 19
