Neurologist Igor Matsokin warned that the first symptoms of dementia can appear 10 or more years before a person receives a formal diagnosis.
Speaking to news outlet aif.ru, Matsokin explained that neurodegenerative processes take years to develop. Initial changes often emerge long before severe memory impairment becomes obvious.

Among the early warning signs, Matsokin identified faster than usual memory decline, reduced capacity for rational thinking, and a gradual drop in cognitive test scores. He noted that a decline in these indicators is a reason to pay closer attention to one's health while time remains.
Prevention and Lifestyle Habits
Regular physical activity, a balanced diet, and addressing specific nutrient deficiencies can help prevent or slow the progression of the disease, according to Matsokin. However, he urged individuals not to self-medicate, emphasizing that any dietary changes or supplement regimens should be discussed with a specialist.
Earlier, neurologist Irina Preobrazhenskaya stated that the brain requires lifelong training just like the physical body. Preobrazhenskaya highlighted solving puzzles and taking outdoor walks as the most beneficial activities for maintaining mental acuity.
