Brain tumors ‘hack’ the communication between neurons, pioneering study finds

A new study suggests that cognitive loss in patients with brain metastases may be due to the interference that cancer produces in neuronal circuits. When cancer spreads in the brain, it changes the brain’s chemistry, interfering with the communication between neurons. This is a very different hypothesis from the one previously accepted, with implications for the diagnosis and treatment of brain metastases. The authors have used artificial intelligence to show that metastasis alters brain activity.
