The relationship between dementia staging scales, cognitive-behavioral scales and functionality in patients with cognitive impairment

Our study demonstrated that both cognitive status and behavioral symptoms are critical in determining the level of functional impairment in cognitive impairments, but their contributions differ in magnitude and focus. As well as cognitive decline, neuropsychiatric symptoms may also need targeted management to reduce their impact on functionality. We need a practical tool that can be used in all stages of dementia, that does not overlook the impact of neuropsychological symptoms, and that can assess ADL according to the needs of patients and carers.
