Dementia

it's coming if...

 * Ability to smell (from easiest to hardest) peppermint fish orange rose leather is tied to early warning sign of dementia.

Risk factors
These links reference animal studies.
 * migraines. figured this out after reading "Blots on a Field: A neuroscience image sleuth finds signs of fabrication in scores of Alzheimer’s articles, threatening a reigning theory of the disease".  It mentioned neuroinflammation and I was like d'you mean like... headaches and migraines? and found this which basically says yes.  Migraines are a significant risk factor for Alzheimer's and generic dementia, but not vascular dementia.
 * herpes - that "blots on a field" article also mentioned herpes as a risk factor
 * gingivitis bacterias - brush yer teeth, floss, salt water rinse, eat leafy greens, avoid refined sugars, cross your fingers and hope someday we get a vaccine for mouth bacteria

speculation

 * if neuroinflammation is a risk factor for dementia then eating turmeric or other anti-inflammatory foods, would that help? are all anti-inflammatory foods neuro antiinflammatory? I only really know about turmeric because i know it helps me with headaches.  are people who regularly eat turmeric not getting dementia at the same rates? i think omega 3s might have been another anti-inflammatory thing? i'm sure there's a million.  but like inflammation is there for a reason, wouldn't it be better to ID the sources of inflammation and make those not happen? like for example if caffeine gives you a headache then don't consume caffeine or whatever.  do people who yo-yo with coffee drinking have higher rates of dementia?  I remember reading that people who repeatedly quit coffee get sensitized to caffeine in a way regular coffee drinkers don't.  i wonder if that's what the end of alzheimers book is all about, is addressing potential sources of neuroinflammation i should go reread it.
