It is a neuropsychiatric disorder that mainly affects the elderly, and it leads to deterioration in memory, thinking ability, behaviour, attention, executive dysfunction, perception, and activities of daily living. The etiology of cognitive disorders is multifactorial including structural damages to brain, genetic, nutritional, and environmental factors. Three major categories include delirium, mild neurocognitive disorders, and major neurocognitive disorders. Some common examples of these disorders are dementia, corticobasal degeneration, Alzheimer's disease, mild cognitive impairment, vascular dementia, etc. Therefore, the chapter will emphasize the different types of cognitive disorders along with their causes and symptoms.

In an agreement meeting, the accompanying rules for not set in stone: (I) the individual is neither ordinary nor insane, (ii) there is proof of cognitive crumbling displayed by either unbiasedly estimated decrease over the long run or potentially an abstract report of decay without anyone else as well as witness related to target cognitive shortages; and (iii) exercises of day by day living are safeguarded and complex instrumental capacities are either unblemished or insignificantly weakened (Winblad et al., 2004). The predominance of MCI is assessed to be somewhere in the range of 10% and 20% among individuals more than 65 years old yet various figures have been referenced (Fig 1). About half of those with MCI progress to dementia inside 5 years of period (Rockwood et al., 1999).
