Mama had two pallidotomies in 1999 (May and October). Has anyone experienced hearing problems and/or sleepwalking after the surgery? Within the past three weeks she has sleepwalked twice. We are not sure if that is an effect of the surgeries or perhaps it is the Comtan that she has recently started taking. The hearing problem has been a periodic problem even before the pallidotomies but it seems worse now. Teresa, Daughter of Mama (57/43/38)
