About Dementia 
• It is a syndrome in which there is deterioration in cognitive function beyond what might be expected from the usual consequences of biological ageing.
• Although dementia mainly affects older people, it is not an inevitable consequence of ageing.
◦ Currently, more than 55 million people live with dementia worldwide, and there are nearly 10 million new cases every year.
• Dementia results from a variety of diseases and injuries that primarily or secondarily affect the brain. 
◦ Alzheimer's disease is the most common form of dementia and may contribute to 60-70% of cases.
It affects memory, thinking, orientation, comprehension, calculation, learning capacity, language, and judgement. 
Consciousness is not affected.
