Scan verdicts. Open evidence only when needed.
Claim 1 of 5Not checkedThe article says that, in newly published research in npj Dementia, the authors found aging dog brains change in similar ways to human brains with dementia, highlighting companion dogs as a natural model of neurodegeneration that could help researchers develop better diagnostics and treatments.View evidenceHide evidence
Not checked
The source study was found, but this claim couldn't be checked against it.
Claim 2 of 5Not checkedThe article says that using the same lab analysis methods used on human samples, the team found abnormal protein deposits in the same regions of the dog brain as in the brains of people with early dementia.View evidenceHide evidence
Not checked
The source study was found, but this claim couldn't be checked against it.
Claim 3 of 5Not checkedThe article says that dogs with high levels of abnormal protein deposits also had unusually elevated levels of glial fibrillary acidic protein (GFAP), which the article presents as a potentially promising biomarker for diagnosing canine cognitive decline and understanding dementia progression in people.View evidenceHide evidence
Not checked
The source study was found, but this claim couldn't be checked against it.
Claim 4 of 5Not checkedThe article says canine cognitive dysfunction affects more than a quarter of dogs over age 12 and that the Dog Aging Project follows more than 50,000 companion dogs over time to study aging and cognition.View evidenceHide evidence

Claim 5 of 5Not checkedThe article says Alzheimer's disease drugs that showed promise in the lab failed in 99% of human clinical trials, and that mice are an imperfect model because they do not naturally develop the protein buildup seen in dementia.View evidenceHide evidence
