That this is the state of "science" is very disappointing, and whenever I see the domain sciencealert, am pretty much trained that it is going to be nonsense.
Sadly, other science publications seem to be following a not dissimilar trend.
Sciencealert seems to summarise academic studies using tabloid journalists.
the journal that's linked seems "okay"... definitely nothing groundbreaking but any research on Alzheimer is better than no research
