Forgetting something in the humdrum of our daily life, be it a trivial chore or an important date, is a common occurrence. We consider it quite normal. But when memory loss becomes a regular affair and starts affecting our functional lives, it becomes a disorder. The umbrella term for this forgetting disorder is dementia, a mental health challenge that impairs your cognitive functions. Alzheimer’s disease falls under the category of dementia, which, according to recent WHO data, affects around 50 million people across the world. This world health body also predicts that the numbers are going to triple by 2050.
