Many people with dementia have other complex health needs, including comorbidity and frailty. Most models of care focus on single diseases and do not take into account the needs of those with comorbidities and dementia. Integration, continuity of care and personalisation are particularly important for this vulnerable group. It is also important to recognise potential barriers to accessing care so that these can be addressed. Issues around providing health care for people with dementia and complex health needs are considered in this article, including management and organisation of care, access to care, models of care, role of the family carer, and prevention of dementia, frailty and long-term conditions.
