## What The Sources Report

- ,7-9 10 11 12 13 Although amyloid-beta and tau hypotheses have been the primary hypotheses in the underlying pathogenesis of AD, emerging evidence suggests that amyloidegenesis can be exacerbated by oxidative stress, leading to AD development and progression. [Zainuddin Muhammad-Safuan (2026); evidence level 3]
- Growing evidence suggests that oxidative stress and impairment of innate antioxidative defence may precede the pathological features of AD and clinical manifestations. [Zainuddin Muhammad-Safuan (2026); evidence level 3]
- Further, these treatments do not stop disease progression and are often associated with adverse effects. [D’Anniballe De Salles Carolina Beatrice (2026); evidence level 4]
- Therefore, the current review elaborated the evidence that demonstrates probiotics and dietary supplements as a treatment's strategy for neurodegenerative diseases. [D’Anniballe De Salles Carolina Beatrice (2026); evidence level 4]

## How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

## Practical Interpretation
