Possibly. Once any underlying or other disease causes have been ruled out, there is a chance your pet may be experiencing cognitive dysfunction. Studies conducted in the early 1990s were the first to identify brain changes in older dogs that were similar to brain changes seen in humans with Alzheimer’s disease (ie, ß-amyloid deposits). Laboratory tests were also developed in the 1990s to detect learning and memory deficits in older dogs. Recently these studies have started on younger dogs in order to fully understand the effect of aging on the canine brain. Similar studies in young and older cats are also ongoing.
While researchers are still not able to identify any genetic cause of why certain animals develop cognitive dysfunction, there are drugs and specific diets available that can help manage cognitive dysfunction in dogs. If you think your pet is becoming senile, discuss it with your veterinarian.
