@jlharsh H started namenda after his 2nd visit to his first neurologist. I never had much faith in that Dr. H got into the A/D program at UCLA and I am so pleased and grateful. His new neurologist there took him off of it because even though he doesn’t have a solid diagnosis, it is not Alzheimer’s, it might be vascular with some frontal lobe action. He had irritation, constipation, dizziness, loss of balance, fogginess & heightened confusion. He says he feels a world of difference and I can actually tell a difference in him, as well. He has been off of it a little over 60 days. The difference was slow until there was suddenly a wow. I can’t say exactly what the timing was.
