Medically Reviewed by Dr. Sarah Jenkins, DVM, Feline Internal Medicine Specialist

Understanding Cognitive Decline in Cats
Cognitive decline in senior cats, sometimes called cognitive dysfunction syndrome, is similar to dementia or cognitive dysfunction disorder in humans. As cats age, changes in their brain can affect memory, learning, awareness, and perception. These changes are progressive and cannot be reversed, but understanding the signs can help you provide the best care for your aging feline companion. Cognitive decline typically affects cats over 10-12 years old, and recognizing the symptoms early can help you adapt your care approach and maintain your cat’s quality of life.
