Neurological Etiology Mild cognitive impairment (MCI) or mild memory loss is a neurological disorder that develops due to the deterioration of a person's normal cognitive abilities over the course of aging process. Mild cognitive impairment (MCI) can be defined as a condition in which an individual suffers a decline in cognitive abilities beyond what is expected in normal aging. However, it is important to understand that these abilities are not clearly identified in daily life activities. It is considered an intermediate condition between memory decline associated with normal aging and severe memory loss, such as dementia. Nevertheless, MCI has also been closely associated with dementia, as it is considered a progression towards it (Petersen, 2004). MCI is considered one of the main precursors of the disease called Alzheimer's disease (AD) which affects neuronal activity in the brain. Mild cognitive impairment has been described as heterogeneous in terms of clinical presentation and etiology. This condition can be classified into two classes, amnestic MCI and non-amnestic MCI. Amnestic MCI is generally considered a type of dementia that causes problems with behavior, thinking and memory (Costa, Monaco, Zabberoni, Peppe, Perri, Fadda, ... Carlesimo, 2014). The process of normal brain function generally involves tightly regulated communication between brain cells, through adequate supply of oxygen and other nutrients, which maintain brain stability. The association between Alzheimer's disease and memory loss may be attributed to the development of plaques and tangles in the brain. These disruptions and death of nerve cells are the main causes of memory failure in patients with mild cognitive impairment (Li, Liu, Gong...... middle of paper ......s ability to use a phone, identify nutritional data, responsibility for medications, groceries, and ability to manage one's finances (Wadley, Okonkwo, Crowe, & Ross-Meadows, 2008). of household appliances has also been applied in some studies Unlike neuropsychological tests which are influenced by educational or ethnic backgrounds, it is evident that the measurement of daily functioning is less influenced by such variables, however there is an increased sensitivity to. identifying MCI using normal functions There are other studies that tend to differ from this reasoning and instead applaud the use of clinical methods in place of traditional methods (Christopher, Marras, Duff-Canning, Koshimori, Chen, Boileau, & ...
