According to the Alzheimer’s Association, every 67 seconds, someone in the U.S. develops dementia, a disease that affects more than 5.3 million Americans.
Although we often think of people getting dementia, we rarely think about senior dogs getting dementia. In dogs it is called cognitive dysfunction disorder (CDD), a disease related to the aging of a dog’s brain. Unlike the normal signs of aging – hearing and vision loss or a general slowing down – CDD often involves a problem with thought processing and a change in personality.
CDD is caused by physical changes in the brain. Research has shown that some older dogs with CDD have brain lesions similar to those that physicians see in Alzheimer’s patients. This results in deterioration in how you dog thinks, learns and remembers. Unfortunately, no one knows what causes dog dementia, but genetics is said to play a part.
