Researchers find strong correlation with musculoskeletal-neurological conditions.

A new study has looked at the links between canine cognitive dysfunction syndrome and other medical conditions in senior dogs.

The research revealed a strong correlation between increased cognitive impairment and musculoskeletal and neurological problems in older dogs.

The study, conducted by scientists from the Royal (Dick) School of Veterinary Studies and the University of Milan, also found a moderate correlation between cognitive decline and metabolic and digestive disorders.

The findings were based on information about 804 dogs of various breeds, all in the last 25 per cent of their expected lifespan, collected via an online survey. Cognitive impairments were evaluated using the Canine Cognitive Assessment Scale and owners were asked about behaviour changes, body condition score and veterinary diagnoses.

The researchers used this information to look at four major types of conditions: musculoskeletal-neurological, digestive, metabolic, and dermatological.

Despite finding correlation between cognitive dysfunction and the other medical conditions, the study found a weak positive correlation between cognitive decline and dermatological symptoms.

Because of the nature of the survey, it was not possible to determine any causality between the different medical problems studied. However, the researchers suggest, based on the findings, that dogs which show signs of cognitive behaviour should be screened for other conditions, especially musculoskeletal disorders.

Rosalind Wrightson, one of the authors of the study, said: “As dogs age, they can develop ill health in the mind and body, but little is known of whether there is any relationship between the two in older dogs.

“Our dog owners’ survey indicates that there is a strong connection between mental and physical conditions in these animals and highlights the need for vets who are treating for one to be aware of the other.”
 
The study was published in the journal Animals.
