Understanding behaviour in dementia: Translating psychological approaches into everyday care

Changes in behaviour, mood and communication are highly prevalent in dementia and are a major driver of caregiver burden, psychotropic medication use, breakdown in care arrangements, service escalation and avoidable hospital admissions. Psychological approaches emphasise understanding these changes as meaningful and rooted in unmet need. Despite a strong evidence base supporting psychosocial interventions, implementation across health and social care systems remains inconsistent. This paper explores how psychological understanding of behaviour and distress can be translated into everyday care. Drawing on clinical experience, focus group findings, practitioner feedback and implementation evidence, it highlights the gap between knowledge and practice and considers how this gap may be addressed at scale. A digitally enabled, psychologically informed workforce capability approach, 6D Dementia®, is presented as an example of how psychological principles can be translated into routine care and implemented at scale. The PLEASE C Me™ framework supports staff and carers to consider the person’s physical health, life story, environment, activity, safety, emotional wellbeing and cognition. The paper argues that psychologists have a critical role not only in formulation and intervention, but in enabling systems to apply psychological thinking consistently in routine care.
