Dementia is an umbrella term for a group of symptoms that affect the memory, and social abilities of a human being. This is a condition in which an individual's cognitive functioning declines and this consequently affects the daily life of the individual. It is mostly seen in older individuals but its occurrence has also been seen in young ones.
As per the data shared by the World Health Organisation (WHO), currently there are 55 million people in the world living with dementia and nearly 10 million new cases are being reported every year.
Not just this, dementia is currently the seventh leading cause of death and is a major cause of disability and dependency among older people world wide.
Several research studies have found different factors behind this condition. A recent study has thrown light on a particular type of deficiency which it says can affect the cognitive functioning of millions of people.
