Implanted Electrodes Loaded With Drugs Could Monitor Brain And Treat It When Necessary

Thursday, June 9, 2011 - 13:00 in Health & Medicine

Electrode Implants Electrodes are already implanted in patient's brains to help monitor and mitigate the effects of several neurological conditions (in this case, Parkinson's). By giving them the ability to administer drugs, microelectrodes could also become first responders when the brain's chemistry or electrical signaling gets out of sync. Thomasbg via Wikimedia Microelectrode arrays implanted in the brain monitor neurological conditions in living patients all the time, sometimes even influencing brain activity if it gets out of line. So, thought researchers at the University of Pittsburgh, why not load one up with drugs so it can deliver chemical therapy to problem sites immediately upon detecting an issue? The team is developing a new polymer-coated electrode that can both monitor and treat a patient immediately, a capability that could be life-changing--or even life-saving--for those living with conditions like epilepsy. Their device is basically a microelectrode like any other, but it has been...
