Radiation is bombarding our brains.

In Alzheimer's, Brain Disorders, Brain Science, Memory and Learning by Brainy Days Ahead

People of all age groups are increasingly exposed to ionizing radiation from various sources, including chronic occupational exposure from nuclear technologies or airline travel and he use of medical diagnostics and therapeutic radiology. More than 62 million CT scans are currently carried out in USA each year, and approximately one third of all diagnostic CT examinations are scans of the head region.

In a new study, an international consortia involving colleagues from Italy, Japan, Germany and Denmark show that even low doses of ionizing radiation induce molecular changes in the brain that resemble the pathologies of Alzheimer’s. The study, conducted on  mice, revealed molecular changes in the hippocampus, which is an important brain region responsible for learning and memory and also known to be negatively affected in Alzheimer’s.
