With aging, almost all processes in our bodies slow down. That's why older adults often have lower metabolic rate, impaired blood flow and cognitive decline.

Your brain works hard 24/7, so it's natural that it becomes tired after tens of years, especially if you're engaged in stressful job or have negative emotions too frequently.

Mental impairment is not an abrupt process as usual. It develops and progresses during many years leading to Alzheimer's disease or some other kind of dementia.

Medical experts say that some patients with mental dysfunction have abnormal proteins, accumulated inside the brain cells and between them.

Another common cause is impaired blood flow in brain arteries, which occurs because fatty plaques stick to the vessels' walls, grow large and block the lumen, reducing blood flow to the neurons.
