Since veterinary medicine has succeeded in extending the lives of many animals, a different challenge has risen – dementia.
Since veterinary medicine has succeeded in extending the lives of many animals, a different challenge has risen – dementia.
A study says that more than one in four dogs aged 11 to 12 experience canine cognitive decline – rising to an alarming 68% by age 15 and 16.
There are some steps that doctors can suggest, says Dr. Connor Ward, a veterinarian in Raps Animal Hospital, in Richmond. But there is no cure – and the impacts of treatments vary dramatically from one patient to another.
“There are medications that help increase blood flow to the brain, which can improve some of the symptoms associated with these conditions,” says Ward. “It is very variable. Between animals of the same size, receiving the same dose, and having the same level of clinical diagnosis, one can improve a lot while another can have a very limited response.”
The signs of dementia in animals have many similarities and differences with symptoms in humans with dementia.
“There are many subtle changes,” says the vet, “including generalized confusion, such as forgetting where things are at home.”
A dog might bark at nothing in the night or seem to forget where his bed is.
“They start sleeping in the middle of the hallway instead of where they normally would because they’re not really aware of what’s going on,” says Ward. “A really common problem when you get to advanced stages is urinating and defecating at home.”
Other symptoms may include wandering aimlessly or hanging in corners. Their sleep patterns may change, with animals becoming restless at night and lethargic during the day. They may be withdrawn and avoid interaction with their people. Cats may reduce or stop their grooming habits. The animal may become aggressive, anxious or irritable, or otherwise show personality changes.
As in the case of any progressive condition, the decision must be made when it is time to humanely end the animal’s life.
“These things are very often subjective,” says Ward. “If a pet is not in pain, seems relatively happy and is not at imminent risk of harm, it makes sense to give it the happiest possible life for as long as possible. It is a discussion with your veterinarian, but in In the end, this decision is for the family.”
