Memory is the ability of an individual to record sensory stimuli, events, information etc., retain them for short or long periods of time and recall the same later when needed . Memory loss, also referred to as amnesia, dementia or memory impairment, is an abnormal degree of forgetfulness and/or inability to recall past events. It is a disorder characterized by loss of intellectual ability sufficiently severe as to interfere with one's occupational or social activities. Memory deficits have long been recognized as severe and consistent neurological disorders associated with numerous psychiatric and neurodegenerative diseases, such as Alzheimer’s disease, Senile dementia, Parkinson’s disease, Huntington’s disease, Trauma, Chronic insomnia, Epileptic disorder and Attention deficit disorders etc. However, the most common cause of memory loss has been found to be Alzheimer’s disease. These Neurodegenerative diseases associated with dementia are characterized by cognitive deficits and memory impairment,thus stimulating research for memory enhancing drugs.
