New guidelines aim to standardize canine dementia diagnosis

An international working group of 12 experts has published what appears to be the first consensus guidelines for diagnosing and monitoring canine cognitive dysfunction syndrome, or CCDS, often called canine dementia. The paper, published online in the Journal of the American Veterinary Medical Association on December 24, 2025, lays out a standardized clinical framework for screening older dogs, ruling out lookalike conditions, and staging disease severity over time. North Carolina State University’s Natasha Olby led the effort, with support in part from the AKC Canine Health Foundation, and the group says the goal is earlier, more consistent recognition of cognitive decline in aging dogs.

Why it matters: For veterinary teams, the biggest shift is practical standardization. CCDS has often been diagnosed inconsistently, in part because signs like disorientation, house-soiling, sleep changes, anxiety, or altered social interactions can overlap with pain, sensory decline, metabolic disease, neurologic disease, and other age-related problems. The new guidance recommends routine surveillance for cognitive changes in senior dogs, use of caregiver questionnaires for screening and follow-up, and a three-tier severity framework intended to improve case recognition, client communication, monitoring, and research consistency. That could help clinics catch cases earlier and create a more repeatable approach to managing geriatric patients. (aaha.org)

What to watch: Next steps will likely center on validation in practice, broader uptake in primary care, and future tools such as blood biomarkers and clinic-friendly cognitive testing to sharpen diagnosis and track progression. (news.ncsu.edu)
