Canine Cognitive Dysfunction (CCD) is a disease prevalent in dogs that exhibit symptoms of dementia or Alzheimer's disease shown in humans. CCD creates pathological changes in the brain that slow the mental functioning of dogs resulting in loss of memory, motor function, and learned behaviors from training early in life. In the dog’s brain, a protein by the name of beta-amyloid accumulates, creating protein deposits called plaques. As the dog ages, nerve cells die, and cerebrospinal fluid fills the empty space left by the dead nerve cells. Canine Cognitive Dysfunction takes effect in older dogs, mostly after 10 years of age. Although there is no known cause of CCD, genetic factors have been shown to contribute to the occurrence of this disease. ==Clinical signs== Dogs with Canine Cognitive Dysfunction may exhibit many symptoms associated senile behavior and dementia. Dogs will often find themselves confused in familiar places of the home, spending long periods of time in one area of the home, not responding to calls or commands, and experiencing abnormal sleeping patterns.〔http://www.lapoflove.com/diseases/CognitiveDysfunctionSyndrome.pdf〕 Although some of these symptoms may be attributed to old age itself, when they are exhibited together, there is a higher likelihood of CCD.
