5 signs of brain aging

Diet, obesity, high blood pressure and high blood sugar will also accelerate the aging process of the brain, thereby affecting the normal function of the brain.

Here are the signs of brain aging.

Poor sleep quality

Brain aging will affect the endocrine regulation of the nervous system, leading to difficulty falling asleep, waking up early, having nightmares and other sleep problems.

Increased risk of depression

Dopamine is a substance secreted by brain cells that can make people feel happy and regulate depression.

As the brain shrinks and ages, the amount of dopamine secreted decreases, which in turn increases the risk of depression.
