Sweep,
I just received my Dog Fancy yesterday. Amazingly enough for coincidences, this article was in it. It's long, but I hope you find it of interest and some help :)

Hope for slipping seniors: Medicine helps dogs with cognitive dysfunction syndrome
By Arnold Plotnick, DVM Sept. US Dog Fancy pp 26-27.
Tim Nolan of New York wasn't too concerned when Colby, his geriatric Shih Tzu stopped greeting him at the door. "I figured that at 16 years old, he wouldn't come leaping out of this dog bed anymore." But a few weeks later, Colby shocked Nolan by urinating on one of the kitchen table legs. "He can be temperamental," Nolan says, "but he has never had an accident in the house."
Fearing a urinary tract infection, Nolan took Colby to his vet, where a complete blood count, serum chemistry analysis, urinalysis, urine culture, and a thyroid test all came back normal. "My vet also grilled me about Colby's behavior. Some or the things that I reported, Like Colby's increased sleeping, his wandering around the apartment at night, his occasional staring off into space -- I thought they were normal, old-age changes," Nolan says. "I was suprised to learn that Colby might have cognitive dysfunction syndrome."
Over the past decade, veterinarians and researches have increasingly recovnized a syndrome in geriatric dogs similar to Alzheimer's disease in humans. Termed cognitive dysfunction syndrome, this decline in memory, learning, perception, and awareness can manifest itself in several ways that dog owners need to recognize.
Much of the tratment for CDS involves drug therapy, including L-deprenyl ---an enzyme inhibitor. About 69-77 percent of dogs with CDS improve within the first month of therapy, according to a study published in the
Journal of Veterinary Internal Medicine in 1998.
Because of chemical changes in the brain, dogs begin to act like their formal selves. Dogs that improve need to receive medication for life, unless the syndrome progresses to the point where drug therapy no longer controls the dog's condition. Most dogs live 18-24 months after diagnosis and die of other health-related problems.
Changes in diet might also help your CDS-affected dog. Vitamins E and C, L-carnitine, lipoic acid, and fish oils have been shown to reduce symptoms. Hill's Pet nutrition in Topeka, Kan. earlier this year introduced a veterinarian-prescribed food that addresses CDS.
You can take steps to make life easier for your dog -- and you. Dogs with decreased fecal or urinary control might need more frequent trips outdoors, installation of a dog door, or reinstitution of paper training, especially if other medical conditions contribute to the problem.
If your dog has hearing difficulty, you may need to use hand signals or keep a 10-ft leash on your dog to maintain control and communication.
Colby responded dramatically to treatment. "About three weeks after I began giving him L-deprenyl, he stopped pacing around the apartment. I no longer get those occasional blank stares," says Nolan. "Best of all, I'm getting my usual tail-wagging, noisy barking greeting when I come home from work."

Clinical Signs of CDS
If your dog exhibits one or more of these symptoms of canine dysfunction syndrome, consult your vet.
*Disorientation. Your dog seems lost and confused, and doesn't recognize familiar people or places.
*Altered or decreased interaction with family. The dog exhibits less interest in receiving attention and doesn't tolerate petting like it once did.
*Decreased greating behavior. When you arrive at home, your dog no longer greets you or greets you with much less entusiasm.
*Changes in sleep and wake cycle. Though a dog might sleep less at night, it sleeps more in a 24-hour period
*Increased aimless activity. Your dog wanders aimlessly or paces.
*Loss of housetraining. The dog urinates or defecates indoors and signals less to go outdoors.
