CRISPR–Cas9–Mediated Genetic Correction for Alzheimer's Disease A Hypothetical Therapeutic Framework
Md Asif Karim, Sohana Parveen Meem, Abdul Kalam Azad. Zenodo (CERN European Organization for Nuclear Research), 2025-12-23
Topic: Amyloid, tau and blood-test diagnosis
The repeated inability of Aβ therapies to pass clinical tests in sporadic AD points to the complexity of the disease and indicates that earlier or more interventions could be necessary. Results:CRISPR/Cas9 gene editing in genes associated with AD, APP, PSEN1, BACE1, and APOE4 was very effective in mitigating β-amyloid deposition, decreasing tau hyperphosphorylation, and improving neuronal function in vivo and in vitro. Efficient delivery through viral and non-viral vectors demonstrated precise gene modification with low off-targeting, with high specificity reported in neuronal cells. Studies on functional outcomes in animal models of AD showed improved learning and memory performance, which was associated with reduced amyloid plaque burden and neuroinflammation. These findings demonstrate not only that CRISPR/Cas9 affects core pathogenic pathways but also that it is translatable to measurable cognitive enhancement, an indication of potential as a disease-modifying therapy.
Key findings
- The repeated inability of Aβ therapies to pass clinical tests in sporadic AD points to the complexity of the disease and indicates that earlier or more interventions could be necessary.
- Results:CRISPR/Cas9 gene editing in genes associated with AD, APP, PSEN1, BACE1, and APOE4 was very effective in mitigating β-amyloid deposition, decreasing tau hyperphosphorylation, and improving neuronal function in vivo and in vitro.
- Efficient delivery through viral and non-viral vectors demonstrated precise gene modification with low off-targeting, with high specificity reported in neuronal cells.
- Studies on functional outcomes in animal models of AD showed improved learning and memory performance, which was associated with reduced amyloid plaque burden and neuroinflammation.
- These findings demonstrate not only that CRISPR/Cas9 affects core pathogenic pathways but also that it is translatable to measurable cognitive enhancement, an indication of potential as a disease-modifying therapy.
Why it matters
This hypothetical framework reports that CRISPR/Cas9 editing of APP, PSEN1, BACE1 and APOE4 reduced β-amyloid deposition, decreased tau hyperphosphorylation and improved learning and memory in animal models. It is a proposed therapeutic framework, not an established treatment for people.

How this study scored 28/100
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 and senior author's track record, so those were left out: it earned 26 of the 92 points we could judge it on, which is 28 out of 100.
