Hearing Loss as a Modifiable Risk Factor for Dementia
Dichter A, Lee EJ, Park T, Tawk K, Ghanbarian E, Abouzari M.. medRxiv, 2026-03-18
Topic: Brain imaging, connectivity and assessment
This study evaluated hearing loss (HL) as a potential early indicator of dementia. We analyzed 16,270 participants from the All of Us database (1980 to 2022), including 1,224 (7.5%) with dementia, matched to controls by U.S. census demographics. Severe survey-reported HL showed the strongest association with dementia (odds ratio [OR] 6.76), followed by sensorineural HL (SNHL) (OR 3.90), smoking (OR 1.71), parental HL (OR 1.48), and hypertension (OR 1.48), all p < 0.001. Effect sizes were largest for severe survey-reported HL (1.91) and SNHL (1.36). These findings indicate that severe survey-reported HL and SNHL are strongly associated with dementia.
Key findings
- These findings indicate that severe survey-reported HL and SNHL are strongly associated with dementia.

How this study scored 16/100
Preprint — not yet peer-reviewed. It scored 37 on the same rubric, but non-peer-reviewed sources are capped at 16, so it shows as 16. Scored zero for study design and randomised / blinded because the record does not state it. We have no data on 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 and multi-centre collaboration, so those were left out: it earned 23 of the 62 points we could judge it on, which is 37 out of 100.
| Component | Points | Why |

| Journal tier | 2 / 10 | Tier 4 — not a peer-reviewed journal (medRxiv) |
| Journal's citation record | 0 / 4 | Not a journal article, so the journal's record does not count |
| Study design | 0 / 12 | No study design recorded — scores zero, not guessed (not stated in the record — scored 0) |
| Strength of evidence | 1 / 5 | Rated “low” in our summary |
| Peer-review validation | 4 / 10 | Preprint — not yet peer-reviewed. Hosted on a preprint server. |

| Points | 23 / 62 | Scored on 12 of 20 parts. We have no data for the rest, so they are left out: 23 of the 62 points we could judge it on is 37 out of 100. |
| Total | 37 / 100 | Capped to 16 because this is not a peer-reviewed article. |
