What are the characteristics of cognitive health in the elderly?

A small decline in memory that does not affect life, the ability to complete daily tasks independently, and normal emotions and social connections have reached the standard.

The 76-year-old Uncle Li who was following me up in the community last week would slap his head and laugh every time he saw me, "Oh, look at my memory. I asked you yesterday about the anti-hypertensive medicine and then forgot about it." But when he turned around, he could clearly tell me the whole story of taking his wife to Hangzhou last week. He handles all the processes, including booking hotels, checking guides, and planning routes. He even knows the free and half-ticket policies of scenic spots for the elderly. Occasional "forgetting small things" like this is completely a normal sign of aging and is not considered cognitive impairment at all.

Regarding the boundaries of cognitive health, there are actually different voices in the academic community. One school prefers "health without disease". As long as there is no diagnosis of pathological cognitive disorders such as Alzheimer's disease and vascular dementia, it is considered cognitive health.； The other group puts more emphasis on "functional adaptability" and believes that the ability to proactively adjust to changes in life must also be added. When the health code was first implemented during the epidemic two years ago, there was an 81-year-old Grandpa Wang in our area. No one taught him, so he took his smartphone to watch short videos and learned for three days. Not only did he know how to use it, but he also set up a small class in the community to teach other elderly people to scan the code and register online. Scholars who hold this view believe that this state of being able to actively learn to deal with new scenarios is a higher-dimensional cognitive health.

In fact, to use an inappropriate analogy, the cognitive system of an old person is like an old car that has been driven for 20 or 30 years. As long as the core components such as the engine and gearbox are not faulty, and the occasional ignition is slower and the air conditioning wind is softer, it will not affect normal driving at all. There is no need to compare the acceleration performance with a new car that has just left the factory. Many family members become extremely nervous when they see that the elderly person has forgotten what they just said, and they insist on taking him to the hospital for a full set of examinations. In fact, this is not necessary. If you ask him to remember his favorite Peking Opera excerpts and how much pension he receives every month, he may remember it more accurately than you do.

If you really want to judge whether there is pathological damage, the key is to see whether the forgetfulness will affect his normal life. I met an aunt before. At first, she forgot to turn off the fire and boiled the porridge dry several times. Later, it progressed to the point where she couldn't find her way home when she went out to buy groceries, and couldn't even name her grandson. This is a sign that she needs to seek medical treatment immediately. Normal aging amnesia refers to “forgetting small things, being able to recall them, and not affecting life”, which completely falls under the category of cognitive health.

To put it bluntly, there has never been a unified standard answer to the cognitive health of the elderly. As long as the elderly feel comfortable living their lives, can make clear arrangements for their lives, and do not cause additional trouble to themselves and their families, that is good enough.
