How are some people's brains able to fight off Alzheimer's disease? Why do some people have the biological signs and damage of Alzheimer's disease , but their memory and intellectual abilities do not decline? Scientists have discovered the answer to this question. Why do some people have the biological signs and damage of Alzheimer's disease, but their memory and intellectual abilities do not decline? Scientists have discovered the answer to this question. According to researchers at the Netherlands Institute for Neuroscience , a rare and special type of immature cells in the brains of such people manage to survive and fight off the damage of the disease, so they do not show symptoms of Alzheimer's. The discovery, published in the journal Cell Stem Cell , raises hopes for the development of completely new treatments to slow the progression of dementia and preserve memory. Why does Alzheimer's disease affect people differently? This has always been a great myst...
Why do you suddenly wake up at 3 am? Here's the scientific reason The problem of waking up at 3 am is linked to the natural fluctuations of the cortisol hormone , and stress increases it. Many people have trouble waking up suddenly at exactly 3 am or between 3 and 4 am. Some consider it a ghost or an ominous sign, but according to science, it is an important signal related to the body's internal clock and hormones. If you also frequently wake up at 3 am, you should not take it lightly. This may indicate that your sleep cycle is disrupted and stress has increased in the body. The main reason for sleep disturbance at this time of night is the natural fluctuations of the cortisol hormone.

This clock controls when we sleep, when we wake up, when we eat, and when we are energetic. This clock is ...
