After chemotherapy treatment, many patients say their mind has been affected. For example they describe symptoms such as feeling confused, memory problems and difficulty concentrating – a phenomenon that has been dubbed “chemobrain” (Cancer Research UK has more information).
The causes are little understood. Are these apparent neuropsychological effects due to a direct physical effect of chemotherapy on the brain? Or could it be the stress and worry involved in chemotherapy that is responsible. Perhaps it’s both. To find out more, Mi Sook Jung at Chungnam National University in South Korea, and colleagues, conducted repeated brain scans and neuropsych tests with breast cancer patients undergoing chemo and compared them with similar cancer patients not on chemo and healthy controls.
Reporting their results in Brain Imaging and Behaviour, the researchers hope a better understanding of the nature of “chemobrain” and its causes will make it possible for health professionals to offer patients better support and care.
