Changes in Brain Due to Allergies




A study has found that the seasonal allergies cause changes in the functioning of brain.

A researcher has also analyzed that hippocampus a part of the brain is liable for forming new memories and the site where neurons continue to form throughout the life.

 

During an allergic reaction, the number of new neurons increases in hippocampus which expands the growth of nervous tissues that may leads to changes in the brain.

 

Pollen is the term, being used for allergic conditions such as runny or stuffy nose, itchy eyes, cough and hey fever.

As per the report from World Health Organization 10 to 30 percents of the population are allergic to hey fever.

 

 While exposing to a model of grass pollen allergy, the researchers has discovered that microglia in the brain of the mice were found deactivated. This shows that allergies can reduce the presence of microglia in brain.

 

Barbara Klein from University of Sazburg in Austria has also said, “We know that the response of immune system in the body is different in case of an allergic reaction v/s a bacterial infection. What this tells us is that the effect on the brain depends on type of immune reaction in the body.”
