What is a cognitive decline?
Cognitive decline usually concerns the progressive loss of cognitive or mental abilities associated with aging. While the brain undoubtedly changes as the body ages as a whole, there is no single formula for the effect of aging on everyone's cognitive ability. Most often, mental aging is associated with generally harmless problems with memory and forgiveness. Other changes that can occur with a cognitive decline include shortening reaction time, language skills and visual spatial skills. In most elderly, this decline is considered a normal part of the aging process and is not usually a sign of illness such as Alzheimer's disease.
Memory reduction is often cited as one feature of cognitive decline. Memory loss is usually slow or non -existent up to the age of 60 and can then accelerate, especially after the age of 70 years. At the age of 70, only about 40 percent of people have a memory ability in the 1930s. Another 60 percent of some memory damage, withTav, which is sometimes referred to as benign senescent oblivion, and this does not significantly affect problems or language skills. At the age of 70, there may be about 30 percent of the deteriorated group in the early stages of Alzheimer's disease.
reduced memory due to aging usually affects only short -term memory. This can make it difficult to absorb new information with cognitive decline, especially if it is communicated verbally. Long -term memory or memories that are many years old are usually not affected. Some older people can even remember long -term memories better than when they were younger.
As well as short -term memory, general cognitive abilities such as planning and problem solving, they also begin to decline around 60 years, while the decline becomes faster after 70 years. Not everyone experiences the same features of cognitive decline.. Although they are not clear, they probably relate to educational background, genetics and the environment. Reduced sleep can be more common because more physical complaints make it more difficult and comfortable to sleep. Other age -related changes can reduce sleep less calm.
has been discussed whether overall intelligence is affected by a cognitive decline. While it seems that non -verbal intelligence decreases with age, verbal intelligence usually remains stable. Other tests show that some aspects of cognitive performance can improve with age. The brightest thing is that when in good health and in the stimulating environment, people can continue to learn and achieve how they age.
