Alzheimer’s disease (AD) has a significant impact on society – in terms of impaired abilities and quality of life, healthcare costs, caregiver burden, lost earnings, and premature deaths. This slide deck discusses the epidemiology and burden of AD and highlights topics as prevalence of dementia, burden of AD and the assessment scales for the quality of life and resource utilization in dementia.

This slide deck has been developed by Joseph Therriault, PhD, McGill University, Montréal, Québec, Canada; and Professor Serge Gauthier, McGill University, Montréal, Québec, Canada, in collaboration with Cambridge (a division of Prime, Cambridge, UK).

Prevalence of Alzheimer’s disease increases with age

The National Institute on Aging-Alzheimer’s Association (NIA-AA) workgroup recently published a research framework which defined AD by neuropathological or biomarker evidence of amyloid-b plaques and tau tangles, rather than clinical symptoms.1 They then aimed to address the question: ‘what is…

Projected increase in the prevalence of Alzheimer’s disease dementia

In 2011, the largest ever demographic generation in the US, known as the baby-boom generation, started to reach age 65.3 As a result of this generation, the number of Americans aged 85 and above is expected to dramatically increase over…

Burden of AD

People living with dementia live with the disease for a long time, and therefore, spend a long time living with disability and depending on caregivers.2 As a result, this significantly contributes to the public health impact of the disease.2,5 Cost…

The burden of AD dementia increases throughout its course

Global function denotes the overall function of an individual and includes cognitive functions, behaviour, and ability to perform activities of daily living (ADLs).7 As AD progresses, the impact on the three domains reduces global function, and increased caregiver burden.8-11 During the…

Demographics of caregivers for patients with dementia

The majority of dementia caregivers live with the patient in the community,1 with 60% of caregivers being married, living with a partner, or in a long-term relationship.1,5 Among primary caregivers of people living with dementia, more than half take care…
