Cadasil,MCI, stroke and migraine

Several days ago I read through the notes from my last two doctor and Neurologist appointments and was surprised at some terms in the remarks that were never discusses with me. I have White Matter disease, small strokes and recently was diagnosed with atypical migraine ( not much headache...mostly nausea and photophobia every day). The notes said possible Cadasil, high risk for Alshimers(can't spell it), MCI likely, migraine and strokes could have caused white matter issues etc. Whoa...This was not good news for me. Why would they not discuss this with me. I take Topamax. Should I be doing anything else? Taking any other tests? Seeing a counselor or something? I can live alone and can drive, cook and so on....just not be out and work or in the light or in crowds very often. Makes me sick. My memory is ok. I'm a little forgetful but not bad. What would the Doctor recommend?
