The silent struggle of ageing with SMI: a narrative review of physical health disparities in older adults with serious mental illness.

PURPOSE: Individuals with serious mental illness (SMI) experience a significantly reduced life expectancy compared to peoplewithout SMI, affecting millions worldwide. While cardiovascular disease, diabetes, and metabolic syndrome are well-recognisedphysical health conditions in this population, this article addresses the unique challenges in managing dementia, cancer,menopause, osteoporosis, and oral health in the context of SMI and ageing.

METHODS

This article presents a conceptually informed narrative review of ageing-related physical health disparities experiencedby people living with SMI. A narrative review approach was adopted to allow for a targeted and iterative synthesis of evidenceacross five underexplored domains: dementia, cancer, menopause, osteoporosis, and oral health. These domains were selecteddue to their public health significance, under-representation in the literature, and relevance to the lived experiences of older adultswith SMI.

RESULTS

Despite their substantial impact on the well-being of individuals with SMI, these areas often receive less attention.Diagnostic overshadowing, limited specialised knowledge among mental health staff about physical health, and the siloed nature ofhealthcare delivery contribute to delays in diagnosis and treatment.

CONCLUSION

To improve health outcomes and life expectancy for people with SMI, there is an urgent need for integratedhealthcare approaches. Collaborative models that bridge the gap between mental and physical healthcare are essential to ensuretimely access to holistic care and address the unique needs of this vulnerable population as they age.
