Did not do a damn thing for my mom. Even when she was in Alzheimers pop had her take b-vitamins. Nothing Latest fad to push sales at walgreens....
I'm sorry for your loss, but was the diagnosis confirmed by an autopsy. The last I read, the only way that diagnosis is confirmed is by an autopsy or an accidental biopsy secondary to severe, penetrating head trauma. Alzheimer's disease is not the only dementia. They need to see extracellular beta amyloid plaques and neurofibrillary tangles inside the nerve cells with a specimen under a microscope, IIRC. There are other signs and symptoms that suggest Alzheimer’s disease, but you need that specimen to confirm it.
Preventing Alzheimer’s disease-related gray matter atrophy by B-vitamin treatment excerpt:
Here, we go further by demonstrating that B-vitamin treatment reduces, by as much as seven fold, the cerebral atrophy in those gray matter (GM) regions specifically vulnerable to the AD process, including the medial temporal lobe.
