Canine Brain Ageing
Brain ageing is the natural process that is largely the result of damage to brain cells caused by free radicals. Free radicals are produced by the body's own metabolism, as well as by environmental pollutants and ultra-violet light. This damage causes biological and physical changes to brain tissue, which in turn can lead to a dog having reduced problem-solving abilities and changes in behaviour. In fact, it is estimated that up to 50% of dogs aged eight years and over show one or more clinical signs of brain ageing. By recognising these signs early, the progression of brain ageing can be limited.
Recognise the signs
A decline in brain function may, at first, result in small changes such as increased sleeping, lack of energy or mild irritability. These are often wrongly believed to be part of the normal ageing process. It is not until the change in behaviour begins to disrupt the relationship between owner and dog that the owner may seek veterinary advice.
There are a number of signs that may develop:
Disorientation
Appears lost in familiar surroundings fails to recognise familiar people or places decreased alertness and aimless behaviour
Interacts less
No longer keen to greet family members does not seek attention or to be petted
Sleep pattern disturbed
Sleeps more during the day and/or less at night wanders around the house at night
House training lost
Doesn't ask to go out , Frequent accidents
The key to diagnosis of brain ageing is your observations as a pet owner. You should report any changes to your vet, especially if there is more than one sign. A thorough physical exam will be performed by your vet to determine if a medical disorder, rather than brain ageing, is the cause.
