Dementia is a health concern worldwide, as there is currently no cure for this neurodegenerative disease.

Dementia can be diagnosed in a person as early as 40 years of age, which has been a source of concern for everyone. Most of the population have a long-held belief that dementia would only affect the elderly.

A comprehensive review of the literature was conducted to gather credible and up-to-date information regarding this disease from previous studies. This review study will therefore aid in the understanding of different types of dementia, as well as the genetic factors that contribute to dementia.
