Unformatted text preview: Cognition involves mental progression of certain information acquired from extrinsic and intrinsic circumstances. This includes memory and thought processes to store, retrieve, and manipulate the information gathered. The cognitive disorders are abnormalities of thinking and memory that are associated with temporary or permanent brain dysfunction (Morrison, 1995). Most often the symptoms target certain problems memory, language, sustaining attention. There are many different forms of cognitive disorders. This disorder may be labeled mild, but it a very serious problem for many aging adults. Mild cognitive impairment (MCI) is the middle or in between disease. It tends to occur in between the stages of normal cognition changes of aging and something more serious as Alzheimer’s disease (AD) or dementia. The reason it is a life changing diagnosis is because research suggests that most patients diagnosed with MCI tend to develop Alzheimer’s disease within the coming years. It is known that with the aging process, most people tend to show decline in the cognitive process, however according to the April 2006 Harvard Men’s Health Watch suggests that statistically by the age of 85, 40% of Americans endure from considerable cognitive impairment. There are certain symptoms and risk factors that can indicate that a person has this impairment, thus leading to a diagnosis by a doctor after thorough examinations with many different forms of treatment options and strategies for the patient and his/her family members to cope with this new problem. The full term, amnestic mild cognitive impairment, distinguishes the condition from the situation where cognitive domains in addition to memory are affected and where a single non-memory domain (eg, language) is affected and where progression to a dementia other than Alzheimer’s disease could be expected (Burns & Zaudig, 2002). After much debate, scientists have come up with a general criterion for MCI, which follows six different classifications. The general criteria for MCI include subjective memory complaints, objective memory impairment, other cognitive capacities memory impairment, normal daily activities, no other neurological and psychiatric factors explaining memory impairment, and no other qualifying symptoms of dementia (Fernandez-Ballesteros et al., 2003). Scientists have argued to classify cognitive impairment for many ages now. However, recently a new accountable system has been introduced that proposed three different aspects that may or may not cause mild cognitive impairment. The first idea suggests that that impairment could be a representation of the early stages of (AD), and the second idea suggests that it is just mere old age. The third, and most likely account is that mild cognitive impairment is a heterogeneous disorder with multiple possible outcomes (Collie & Maruff, 2002)....
