I have events that start with not being able to speak coherently or not being able to read words. This lasts about 1-2 minutes. Then I have a headache and sometimes confusion of where I am. Have short term memory loss and difficulty remembering numbers or new concepts for a few weeks then it passes. Have had MRIs…nothing shown…except normal pressure hydrocephalus that has been declined as the reason. Has anyone experienced these symptoms and recovered or discovered cause and treatment? Have had many tests …difficulty getting into neuropsych memory evaluation. Been searching for the answers for years. Appreciate any ideas about it.
