I'd noted "heavy & non-heavy", unclear what the emoji use is supposed to indicate.

Yes, the set of diseases has similar biological presentation (prion or not). But no, the differences causing the association do not mean the significant increase is in both cases & controls. I'd asked for if you could link to any research finding no association & you didn't, just said it's seen in people without disease (which it surely is, but at significant lower levels than those w the disease which is the point).

The earths crust composition is a constant, the concentration in the atmosphere is not & has increased. As has the incidence of these diseases. The timelines of both increases are concordant. No one has studied the source of the increase in exposure from increased concentration in the air.

So as long as no one studies it, yep, the information of people observing/collecting data will not be places other than internet sites/youtube. Like the speaker in the video who observed change in solar panels/tested serial samples which were well beyond toxic levels for these metals, including aluminum. There's nothing odd about that. What is odd is the absence of scientific inquiry into this topic & the highly emotional responses.

A simpler & correct response would've been: no one's studied the source of the increase in aerosolized metals in the air, which are associated with these neurodegenerative diseases that are increasing in incidence.
