# Unexpected Causes of Memory and Cognitive Decline Revealed

A "beer" belly, deteriorating vision, and rare outings into nature accelerate the development of cognitive impairments

This was reported by gazeta.ru, citing Andrey Ilnitsky — a Russian geriatrician, expert of the social project "Dementia.net," and Doctor of Medical Sciences.

As the specialist notes, many people fear senile dementia, yet only seriously think about it after the age of 65. Meanwhile, the doctor strongly recommends following so-called behavioral hygiene for the brain starting at a young age. And this involves far more than just proper nutrition and adequate sleep.

"It's better to exercise or walk together with someone, because socialization and communication are additionally engaged," explains Ilnitsky. Physical activity alone also brings benefits, but joint workouts — in pairs or in groups — provide significantly more powerful brain protection.

It is equally important to monitor key body indicators: body mass index, blood pressure, heart rate, cholesterol, and glucose levels. Any deviation must be gently and promptly corrected.

The expert pays particular attention to one's place of residence. A high concentration of pollutants — microplastics, hydrocarbon combustion products — is now recognized as one of the risk factors for dementia. Ilnitsky calls this a quasi-infectious process: harmful particles trigger inflammation, oxidative stress, and increase the production of substances directly linked to the development of the disease. In essence, this mechanism resembles the body's interaction with pathogenic microorganisms.

"If possible, choose a neighborhood with green spaces, or at least get out into nature on weekends," the expert advises.

Another alarming signal is excess weight, and especially visceral fat. Accumulating around internal organs, it visually manifests in the abdominal area and releases pro-inflammatory cytokines — molecules capable of damaging the brain and, over time, provoking dementia. According to the doctor, even a weight reduction of just 3–5% can noticeably lower the risks.

The condition of one's eyesight should not be underestimated either. "When a person has poor vision, the volume of information reaching the brain decreases. And this is already considered a risk factor for cognitive impairments," emphasizes Ilnitsky.

It is worth thinking about dementia prevention long before retirement. As early as age 35, men may develop a so-called "beer" belly — and this is a direct signal of visceral fat accumulation, which is dangerous for the brain. "If a belly appeared early, it's necessary to get your lifestyle in order, see doctors in a timely manner, and treat any identified conditions," notes Ilnitsky. The sooner measures are taken, the longer clear thinking can be preserved.

After age 65, vigilance alone is no longer enough — regular screening is essential. There is a simple test: ask a loved one to name three words, distract them with conversation, and then ask them to repeat the words.

"Couldn't do it? That's a reason to visit your doctor and also check hearing, vision, blood pressure, blood sugar, mood, and weight — all of this together helps detect the problem at its onset," the specialist concluded.
