Infections damage ability to form spatial memories

Increased inflammation following an infection impairs the brain's ability to form spatial memories, according to new research. The impairment results from a decrease in glucose metabolism in the brain's memory center, disrupting the neural circuits involved in learning and memory. This is the first study to image the effects of inflammation on the brain. The findings help explain why inflammation impairs memory and could spur the development of new drugs targeting the immune system to treat dementia.
