According to Dr. Curtis Dewey, a veterinary neurologist with extensive knowledge on this subject, estimates of the prevalence of canine cognition decline (CCD) generally vary between 14% and 35% of the pet dog population, in dogs 11-12 years old 28% and in dogs 15-16 years old 68%; however, he notes that those percentages are likely an under estimation of how common the disorder is. As with people with Alzheimer’s disease (AD), the prevalence of CCD increases dramatically with age. Dogs may show evidence of brain changes as early as 6 years of age. Many dogs with mild impairment will progress to moderate impairment and those with moderate disease often progress to severe impairment.
Dogs with CCD are less likely to develop such severe impairment as occurs in people with AD. Affected dogs typically respond well to medical intervention, especially if instituted early in the disease process. There is also evidence in both AD and CCD that preventive measures such as dietary changes and environmental enrichment can both delay the onset and slow the progression of cognitive decline. This information suggests that simple preventive measures against CCD including dietary supplements as provided in CogniCaps, may be generally advisable in pet dogs as they near middle age.
