Background
There is evidence to suggest that older people with Bipolar Disorder (BD) are more likely to demonstrate poor levels of functioning and score lower on well-being scales compared to non-clinical controls, even when in remission (Depp et al., 2006). To our knowledge, this is the first review paper to identify how quality of life and functioning has been measured in an older adult BD population.

Methods
We conducted a systematic review of studies including a quantitative measure of psychosocial functioning or quality of life and older people over the age of 50 with a formal diagnosis of BD I or II.

Results
Eleven studies (N = 726, mean age range 59.8 to 71.1) were included in the review, demonstrating a significant lack of research in the area compered to younger people with BD. The most commonly used measure of functioning was the Global Assessment of Functioning Scale (GAF) and results indicated that older adults with BD demonstrate a wide range of functioning.

Limitations
The review used a comprehensive and systematic search strategy, however, very few eligible studies were available for review. The pooled analyses and reported means must be interpreted with caution due to the relatively small sample sizes.

Conclusions
Older people with BD present with a wide range of functioning, ranging ‘major impairment’ to ‘superior’ scores. No existing validated measure assessing the psychosocial functioning or quality of life of older people with BD could be identified. Such a tool should be developed for use in future research.
