X-Message-Number: 24402 From: Date: Sat, 17 Jul 2004 22:23:10 EDT Subject: deprenyl for dogs Content-Language: en Deprenyl (selegiline, eldepryl, jumex) for many years has been one of the "possibly" effective anti-aging supplements for humans. The material below, taken from the web, was written by a veterinarian. One of the interesting sentences is >the high frequency with which the syndrome [cognitive dysfunction] is seen in older dogs >does not make it normal. I wonder if this doctor would agree that aging itself, in dogs or humans, isn't normal? After all, the primary meaning of "normal" is right or healthy, not "typical" or usual. Also, of course, the efficacy of deprenyl in treating cognitive dysfunction of old dogs suggests that it may improve or extend life for old humans. Robert Ettinger CANINE COGNITIVE DYSFUNCTION Pet owners have long been frustrated by age related behavior problems involving loss of house-training, apparent memory loss or disorientation, sleep disturbances (either waking at the wrong time or sleeping unusually deeply) and loss of interest in social activities with the family. Such behavior changes are often written off as being normal aging. A recent study at the University of California School of Veterinary Medicine demonstrates how common these observations are: out of 69 dogs participating, 32% of 11 year old dogs were affected by this syndrome and that 100% of dogs 16 years of age older were affected. Still, the high frequency with which the syndrome is seen in older dogs does not make it normal. Other studies have shown that dogs affected by this syndrome show deposition of a protein called amyloid in their brains in patterns very similar to the amyloid plaques found in the brains of humans with Alzheimer s disease. Cognitive dysfunction is associated with depletion of dopamine, the neurotransmitter mentioned above. As described above, also, L-Deprenyl helps prolong dopamine activity which may account for part of its efficacy in treating cognitive dysfunction. Further, dopamine breakdown results in harmful biochemicals known as free radicals. The use of L-Deprenyl also helps reduce amounts of free radicals in the brain.
