Severe stress makes the brain shrink! Why?
Stress at the lightest level can spur creative person. However, a danger if allowed to continue to acute stress.
Here are some things that happen in the brain when a person experiences stress in the long run, as reported by Buzzle.
1. Damage to brain cells.
Under stress, the brain releases the hormone glucocorticoids which gradually weakens the brain cells and eventually kills the cells. Adrenaline was released during stress, which makes people feel uneasy and confused. When the adrenaline is not removed, it can lead to excess production of glucocorticoids.
2. Debilitating memory.
Increased glucocorticoid prolonged exposure may weaken the memory, making it difficult to connect with the nerve endings of new brain cells.
This condition also makes it increasingly difficult to transmit information back and forth, causing short-term memory loss. This is one of the reasons that induce the onset of dementia and Alzheimer's in humans.
3. Brain shrinks.
Stress can cause the hippocampus to shrink the area for some time. This condition is more often seen in victims of trauma and violence. With the shrinking of the brain, making it difficult for people to focus and remember facts. It also affects motor skills and make it difficult to plan anything.
4. Pinching the nerve.
Stress can drastically reduce the blood circulation in the brain, thereby increasing the chances of suffering a stroke. Nerves and blood vessels begin to shrink or pinching together, blocking the supply of blood, oxygen and nutrients to the brain, delaying the brain's ability to heal itself faster.
5. Causes of depression.
Stress greatly affects the release of endorphins or hormones that make people feel happy. It can lead to depression, in which individuals lose hope and found everything to be very difficult for him.
The second reason, stress causes cortisol levels rise in the brain, which affects overall metabolism, which makes depressed people tend to be active and lethargy.
