Mental Health: Dementia

A syndrome known as dementia results in a loss of cognitive function (i.e., the ability to process ideas) that is more severe than what would be expected from the ordinary consequences of biological aging. Usually, it has a chronic or progressive nature. All of these functions—memory, direction, thinking, understanding, computation, learning capacity, language, and judgment—are affected. No one's state of consciousness is altered. Changes in mood, emotional control, behaviour, or motivation frequently coexist with and sometimes precede the deterioration of cognitive function

Dementia rates

More than 60% of the 55 million people with dementia worldwide live in low- and middle-income countries. Due to the fact that the proportion of older people in the population is rising in practically every nation, it is predicted that this number would rise to 78 million in 2030 and 139 million in 2050.
