Is lser ablation being tested on people with generalized epilepsy?

Tested?: I'm not sure of your question really? Laser ablation which also goes by the name of the Visualase system here in the U.S. has been FDA approved to be used in treating generalized epilepsy for at least the past 4-5 years that I'm aware. Way beyond testing. It is successfully used in patients with good outcomes who are not responding to their medications well. Cheers!

Yes, research is on: Laser thermal ablation is gaining momentum as an effective and potentially cost-effective alternative to conventional neurosurgery in patients with epilepsy. There is ongoing research but not widely used yet. Check out this case done at Children's hospital in Texas on a 9 y/o; http://texaschildrens.org/epilepsylasersurgery/
