Teri,

Thanks for the links.

I do have the MTHFR C677T and a second gene A...... on the same chromosome that are the cause of the hyperhomocysteinemia.  My hematologist has me on the Folgard RX for that.  There is a long family history of headaches migraine-type and strokes.  I recently spoke to an aunt who indicated she never had a migraine but used to have cluster headaches.  She seemed surprised when I told her they were related and who else in the family had them. 

All of my docs have used terms Complex and Complicated interchangeably.  I have had stroke-like symptoms... aphasia, left-sded weakness, neuralgia and visual disturbance, most recently loss of words & memory and complete debility with an almost daily headache now since April.  Recently had a neuropsych completed and dx'd with the MCI.

I found the articles both on the Namenda and gene interesting.  My neuro did not seem to think it would help with the headaches.  I have noticed a brief period of relief shortly after taking the Namenda, but it does not last very long yet.  I am still on the trial pack.  So far I am not experiencing any negative side effects.
