Trends & Statistics
There are about 50 million people having dementia worldwide. By 2030, this figure may reach 78 million, that works out to be a 4% increase annually. Statistically, this condition is more prominent in adults above the age of 65, however, the trend is shifting toward the younger adults. Early onset can manifest as early as 40s, these cohorts may suffer greater impacts on financial, social and family as they struggle with self-esteem, emotion, behavioural and lifestyle changes.

Assessment and Diagnosis
3 common methods of assessment:Â
• Medical history
• Physical exam
• Neurological testsÂ
Â
Other medical professionals may also use cognitive and neuropsychological tests, laboratory tests, brain scans, psychiatric evaluation, and genetic tests, depending on the severity and availability of technologies at the facility.Â
Â
Over the years, there are many variations of quality of life (QoL) assessment tools being introduced to measure the implication of dementia on QoL, such as Dementia Quality of Life (DQoL), Quality of Life-Alzheimer’s Disease (QOL-AD), Dementia Care Mapping (DCM), Geriatric Quality of Life-Dementia (GQOL-D). To date, there is no single best tool in the sector. The application is often depending on the competency of the specialist and stages of dementia.
Â
Even though there is no cure available for Alzheimer’s and other common dementias, early diagnosis can help you and your family make plans for the future.
