Study analyses increased risk factors for canine dementia
The study aimed to ascertain the prevalence of CCD more thoroughly.
Research sheds light on CCD and associated characteristics.

A research team from the University of Washington, Seattle, has found that dogs' risk of developing canine cognitive dysfunction (CCD) increases by 52 per cent with each year.

Published in Scientific Reports, the study used a CCD rating scale developed by previous researchers, with a large cohort of dogs from the Dog Aging Project (DAP) assessed.

Analysing data from 15,019 dogs, researchers took age, sex, breed, health and activity level into consideration, along with behaviours associated with cognitive decline to score each dog on a scale.

Analysing the results, it was found that a total of 1.4 per cent of the dogs were classified as having CCD. As well as this, dogs with lower levels of activity over the past year has a higher association with CCD.

Of the dogs studied, odds of CCD were 6.5 times higher in those with lower activity levels.

There was also a higher prevalence of CCD among dogs who had ever previously had a neurological disorder, as well as dogs with a history of ear or eye disorders.

Using the multivariable logistic regression model, taking several factors into account, the study indicated a positive association between age and CCD in companion dogs. This is expected, given the progressive nature of the condition.
