Here's my entry - as far as I'm aware, my mother has never had a cold sore. Maybe when she was a child but not in my memory.
But the herpes family of viruses can lurk for decades in the body. Think of shingles - you must have had chicken pox at one time to develop shingles. Our bodies are so complex and everything is interrelated.
Mind you I'm always wary about these statistical analysis (analysese?) By adulthood close to 90% of the population has exposure to the HSV-1 virus, so I'm not sure it comes under the category of a smoking gun. In fact, if that 90% figure is really correct, the fact that 70% of people with AD show such exposure, surely a case could be made that in fact it exposure to the virus actually decrease your risk of catching AD (since if it was truly random you would expect AD patients to show the same level - i.e. 90%). I realise that exposure and finding it in the brain isn't necessarily the same thing though. It doesn't seem particularly new research either - this link was reported at least in 1997.
As to dog ownership - there are all sorts of things that dog ownership exposes you to. Do you know if you own a dog you are 5 times (I think that was the number) more likely to find a dead body than a non dog owner? Not of course the ownership per se but the walking of a four legged sniffing machine is what causes that.

Like all of you, I'm a little sceptical about some of the research on alzheimer's particulary when time and money could be spent better elsewhere. However it does not harm to keep everyone informed of any research that crops up.
Just as I had decided to ask if anyone knew if animals suffer from dementias, Craig posted this very interesting information. Both his links are highly relevant. It seems that dogs indeed can show characteristics of dementia, and post mortem studies have shown that their brains also get gunged up with amyloid plaques. I am going to study the information in more detail before I ask any more questions, but I am very excited by this news, and hope the scientists will undertake animal and human studies jointly.
We once had a thirteen year old goat and the vet said that it was unusual for goats to live more than ten years.
This goat had a strong heart and lungs, but she gave up the will to live and became very depressed. She just walked round and round in circles, refusing to eat anything and losing so much weight. The vet thought that she may have developed liver disease and toxins had damaged her brain, but we never knew for certain.
I've heard of cats and dogs who have also lost their memory or start behaving in strange ways. It would be interesting to see if there are any similarities with dementia in people.
We need to find out as much as possible about this awful disease so it can be treated or at least brought under control.
I remember the aluminuim pans thread well. When the person wrote to me and said I caused my husband to have A.S. I was furious. Never used them. (Peter's ex wife did)!!!
As for cold sores, Peter always on a monthly basis had one ???
As for the person with 1.99 legs well the mind just boggles.
Yep Mum and I have suffered from them for years. However something else struck me about the stats, the older you get the more likely you are to be exposed to the HSV virus AND develop alzeimhers purely because you have had an extended life span! Statistics were once described to me as "an exact science - that is no one knows exactly what they prove" lol.
I should stress this is a line of thought based on absolutely no scientific research at all which I know of but just something that popped into my head; not terribly serious in the greater scheme of things. However, I'll float it for your reactions.
Sweeteners were widely introduced to our diet in the 1940s, when war-time rationing of sugar was necessary - at the time it would have been saccharin. So the WW2 adult population (which would include my parents) & the 'war-baby' generation were heavily exposed to them. Food manufacturers adopted them into ready-made 'shop-bought' cakes etc. for reasons of cost so they stayed n our diet after rationing finished in the 1950s. Following on came the concept of Ready Meals and convenience foods, many loaded with preservatives, salt and yes - artificial sweeteners, now mainly NutraSweet, Aspartame & sodium saccharin.
I've been eating this 'new generation' of food all my life, so I'm certainly not preaching about it. I'm probably the ideal guinea pig, if anyone wants to carve my body up when I'm finished with it!
