Back in 2015 I had a bad fall and had a bad bleed in my head. And had the operation where they drilled a hole and took out part of my skull. 2 years later I'm becoming more and more forgetful. I'm 56 years old. One year after the operation I had open heart surgery where they replace the mitral valve in my heart which was leaking. Does anyone else have the problem of forgetfulness that I do?
