A new study has found that reduced oxygen supply alleviates some of the cognitive impairment in mice caused by whole brain radiation therapy

However, when mice were treated with chronic hypoxia for about three weeks, beginning one month after radiation exposure, they showed significant improvement in this area, which was maintained for at least two months after returning to normal oxygen levels.
The radiation treatment also caused an early decline in contextual learning and memory, but these deficiencies were transient and dissipated within three months post-radiation.
The study has been recently published in the online journal PLoS ONE.
