I come across that Alzheimer's news yesterday on The Guardian and Público (a Portuguese newspaper) - links below. Become so upset I wasn't even able to post about it.
Why did I become so upset? Because my paternal grandmother has Alzheimer's and she is getting worst and worst. I was like,"wait, a virus may be the cause (or a sympthom, they aren't sure whcih is it). Two strands of herpes virus? Really?"
A virus is, I think easier to deal with/find a solution than for the other views on Alzheimer's. But the, the article makes it clear "The Alzheimer’s community remains cautious about the findings. “Possible roles for microbes and viruses in Alzheimer's disease have been suggested and studied for decades, but previous research has not explained how they may be connected. This is the first study to provide evidence based on multiple, large data sets that lends support to this idea,” says Keith Fargo, director of scientific programs and outreach at the Alzheimer’s Association. But “more research is needed to discover exactly what roles, if any, they play. The new findings do not prove that the viruses cause the onset or contribute to the progression of Alzheimer's disease.”
Sadly it seems that more researche is necessary to see ifthe virus paly a role, and if so, which. Meanong, effective treatement for Alzheimer's will not come in tiem for my grandmother and many suffering from it right now. But they may be close. Or may be more willing to look intp other possibilities and come up with something that truly works and stops, or even reverses, this horrible disease.
https://www.theguardian.com/society/2018/jun/21/alzheimers-link-to-herpes-virus-in-brain-say-scientistshttps://www.publico.pt/2018/06/21/ciencia/noticia/encontrada-uma-ligacao-entre-alzheimer-e-a-presenca-de-virus-no-cerebro-1835431The Analysis of a Million-Plus Genomes Points to Blurring Lines Among Brain Disorders is interesting, but some things seem to be a little at odds with the Alzheimer's article.
For example this: "Is lower academic achievement in early life tied to the same gene changes as an increased risk for Alzheimer’s in older age? That is one of dozens of possible deductions to be drawn from the largest genomic study of brain conditions ever conducted, research that obscures what often have been considered clear diagnostic borders."
It may be some people with lower academic achievement in early life may have Alzheimer's , but that does not apply to many with the illness. And, as if the other article suggests, it may be a virus that most of us carry, and, for some reason gets activated at a point, lower academic achievement in early life may have nothing to do with it.
It is, or used to me, thought that an active mental life tillolder age may be a good way of preventing Alzheimer's. I alwways found that one a little strange. Several Alzheimer's patients kept a very active mental life until the disease showed its ugly head.
“One of the big messages is that psychiatric disorders turned out to be very connected on the genetic level,” - Not much of a surprise here. The tendency is for Psychiatric disorders to dissapear and be included in Neurology (I have talked about in the past).
Psychiatry, and the way Psychiatric disordersa are approached is outdated. Psychiatric don't exist in a vacuum and are, somehow, connected to biology/nuerobiology/genes. We just don't know enough. Yet.
"But because the study was a “hypothesis-free approach,” as Anttila describes it, showing only statistical associations among genes, not proof of a common genetic basis, the findings are only a starting point for digging deeper “to better understand how these disorders arise,” he says. " I short,they still don't know how things really work, which means they still don't know how really to solve them.
“I was personally surprised by the lack of such correlations between neurological disorders and psychiatric ones,” he says, noting that he would have expected depression, for example, to show overlap with some neurological diseases." I will argue that depression (major clinical depression, post-partum or thyroid one is a different matter) is a neurologial disorder. To be fair, if it was up to me the concept of psychatric disorder would disappear.
"Standing out from this crowd at the end of the shared-variant spectrum was schizophrenia, which overlapped with all of the psychiatric disorders except anxiety. PTSD, meanwhile, showed no significant association with any of them." No surprise there. PTSD, I would say is more connected to the nervous system (or parts of it).
Bottom line, they may know overlaps, etc., but remain clueless about exactly what causes the illneses, why, and how to cure them. Hope science finds cures/solutions soon.
