Dementia is an altered physiological and psychological as well as neurological abnormality that disrupts the affected person’s life, life style, personality, memory and learning abilities and cognitive performance [1]. People suffering from dementia become solely dependent upon the family members, care-givers and related health-care professionals [1]. According to the world health organization (WHO), more than 55 million people have been suffering from dementia worldwide [1]. More than 60% of them live in the underdeveloped and developing countries [1]. Alarmingly, more than 10 million cases of demented people have been added each year [1]. No individual cause could be ascribed with dementia patho-mechanism [1]. Rather, dementia could be considered as an outcome of dysregulation related with multiple metabolic, homeostatic, hormonal and neuronal activities [1].
