Staving off Alzheimer’s has many schools of thought

Do you remember what I wrote about Alzheimer’s last month. I’m fuzzy about it, too. Here’s a restatement. More than a century ago Alois Alzheimer described misshapen proteins, or peptides, in the brains of patients with dementia. Studies seem to confirm an association, but not necessarily cause and effect. Treatments to clear these proteins from the brain have produced disappointing results. While we wait for clarification, what might help?
