Lithium in drinking water and Alzheimer's dementia: Epidemiological Findings from National Data Base of Japan
Masaaki Muronaga, Takeshi Terao, Kentaro Kohno, Hirofumi Hirakawa, Toshihiko Izumi, Masaki Etoh. Bipolar disorders, 2022-09-13
Topic: Air pollution and environmental exposures
The adjusted model showed a significant inverse association of lithium levels with female, but not with male, or total prevalence of AD. These findings suggest that higher lithium levels in drinking water may be associated with lower prevalence of AD in female, but not male, populations.

How this study scored 41/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record, multi-centre collaboration and free to read, so those were left out: it earned 23 of the 56 points we could judge it on, which is 41 out of 100.
