Dementia Research: A Comprehensive Overview

Dementia is a general term describing irreversible diseases that affect peoples memory and capabilities. In recent years, its global prevalence has been rising gradually. Several studies have focused on different areas of dementia. This article reviews current knowledge of dementia from ten aspects, including types, etiology, symptoms, diagnosis, treatment, prognosis, ethical policies, and the latest news on dementia. Most studies agree that the most common type of dementia is Alzheimers disease, which accounts for 60% to 80% of cases; the average life expectancy after diagnosis is 5 to 10 years. Recent National Health Service (NHS) policy and the General Medical Council (GMC) have listed caregiving suggestions for doctors and carers of dementia patients. The NHS explained the reasons it denied drugs intended to treat dementia. Our review summarises basic information about dementia, analyses the policies and treatment resources that need to be addressed or improved, and indicates the next steps to control this global problem.
