There are many causes of stress, such as unhappy marriages, jobs less stressful, traumatic events, up to trivial issues such as congestion. If chronic stress is left then the impact is quite harmful to the brain.

When stressed the body releases chemicals. In the long run these chemicals will be toxic to brain tissue, it can even kill brain cells when chemicals called corticosteroids were abundant and long lasting.

Corticosteroids are actually required by the body to increase the speed of reaction to the threat or often referred to resist or escape response (fight or flight), by suppressing the immune system and increase the amount of sugar in the blood circulation.

The hippocampus, a part of the brain that is responsible in terms of memory formation, is the most vulnerable to stress. That’s why experts think stress is closely related to the occurrence of dementia.

The scientists found a brain condition that narrowed it as they did brain scans of patients suffering from post traumatic stress resulting from the attacks 9/11. The smaller size of the hippocampus was almost equal to the size of the brains of elderly patients with dementia.

Even so, experts say the results may be too early to determine the effects of stress on the brain because of the number of respondents is too small.

While some studies have found that war veterans suffering from post traumatic syndrome also suffer from a severe brain disorder.

The study also revealed that the stress experienced by middle age may increase the risk of Alzheimer’s. They are often under stress and anxiety are also two times higher risk of suffering from dementia.
