Mild cognitive impairment is a slow loss of memory and one’s ability to think. It is noticeable to the patient himself, his family and friends. It creates problems related to language, thinking, memory and judgment. It is not a serious condition to affect one’s normal daily life and independent function. It affects 15 to 20% of old people above the age of 65 years. It can be measured by cognitive tests. It may increase the risk of development of dementia, Alzheimer‘s disease, and other neurological disorders.
Is Mild Cognitive Impairment A Serious Condition?
Mild cognitive impairment (MCI) is a condition marked by problems related to memory and thinking. It lies in between normal decline of cognitive behavior during aging and dementia and Alzheimer disease. It affects old above 65 years. Alzheimer’s Association states that 10-20% of this age group has mild cognitive impairment. Identifying mild cognitive impairment is often tricky as memory and thinking problems are often considered as a normal phenomenon of aging.
Mild cognitive impairment leads to impairments of one’s memory, language, thinking and judgment more than age-related changes. These changes are noticed by the affected person himself, his family and close friends. These changes are not strong enough to influence one’s daily routine and usual activities. Mild cognitive impairment is not a serious condition. Normally, these changes do not get worse and get better on its own. Only a few cases of mild cognitive impairment may transform into dementia, Alzheimer’s disease, and other neurological problems.
It is impossible to keep the normal function of brain up to 100% when aging proceeds. The brain cells continue to deteriorating during aging. It becomes challenging to delay or reverse such changes. It is better to monitor such changes at the earliest and control them. However, new research studies have made it possible to delay and reverse such changes. Diet management can also contribute to this.
