British scientists have conducted several studies to prove that inflammation in the brain of an elderly person in connection with the infection has a negative impact on the mechanisms of memory, spatial memories, says medical News Today. A reduced level of immunity in old age leads to more serious infections that can cause cognitive impairment. The presence of inflammation in the nervous tissue is one of the causes of Alzheimer's disease and dementia.
To confirm his theory, Dr. Harrison, along with his colleagues conducted an experiment, which was attended by 20 people. Half received injections with saline solution (placebo), the second group had vaccination against typhoid. Next, subjects were examined using the technique of positron emission tomography. The method allowed us to assess the degree of inflammation in the brain.
Research has proven that inflammation leads to lower levels of glucose metabolism in the medial temporal lobe. This structure is responsible for adequate perception of space. When reduced metabolism is impaired spatial memory. Note that procedural memory was not affected.
Experts are sure enough a simple infection that has damaged memory. In a special risk group elderly people. The presence of acute or chronic infection may be a risk factor for developing Alzheimer's disease. Control inflammation will give the chance to reduce progressive deterioration of mental abilities.
