Plain-English summary
Cognitive dysfunction syndrome (CDS) is a common but often overlooked condition in pets that affects their behavior and mental abilities, similar to Alzheimer's disease in people. It happens due to the loss of brain cells and inflammation in the nervous system, and researchers are still working to understand it better to improve how we diagnose and treat it. To diagnose CDS, veterinarians usually rule out other issues and may use specific assessment tools designed for dogs. Treatment tends to work best when it is personalized and started early in the disease. Overall, early and tailored care can lead to better outcomes for pets with this condition.
Abstract
Cognitive dysfunction syndrome (CDS) is a common, yet underdiagnosed, neurobehavioral disease of domestic animals. Much like its human counterpart, Alzheimer's disease, CDS is the result of neuronal loss and inflammatory changes in the central nervous system; however, the specific pathophysiology of the disease continues to be researched in efforts to advance diagnostics, prognosis, and treatment. Diagnosis is typically conducted by ruling out possibilities and using assessment tools, including the Canine Dementia Scale and the Canine Cognitive Dysfunction Rating Scale. Treatment is often most successful when a tailored, multimodal approach is initiated early in the disease progression.
