Search for an article called "Lyrica and neurontin are death sentence to new synapses"
I just saw it the other day.
This is news to me and if it is accurate it would make it a really shitty choice to help someone get through benzo withdrawals or other addictions.
I posted this in the 'feeling dumber' lyrica thread, in response to the presentation of that article by one poster:
Vaya said:....not a good article by any stretch, and not nearly scientific enough to be believable. Consider:
Browsing the rest of the website will find you discovering weight-loss advertisements and a general lack of credibility to the content. Articles with dramatic titles like "Neurontin and Lyrica are a death sentence..." rarely provide any citations for the claims they make, and this article is no different.
"However, such uses can no longer be justified because the actual mechanism of the drugs is finally understood and they are creating a significant long-term reduction in nerve health."
What mechanism of action is that? Calcium channel flow reduction resulting in hyperpolarized, and thus less excitable, nerve cells? Or is it the result of more contemporary research? Irregardless of which it is that they omitted, the article still does not cite scientific evidence to explain why pregabalin's "actual mechanism" (which they didn't bother to define) would have any bearing on the "health" of nerve cells at all. For instance, in this context, define "health"? Is that the velocity with which it conducts its signal? is it the strength of axonal growth, re/generative abilities, or myelin integrity that determines the "health" of a nerve cell?
"The researchers in the above study try to downplay the serious nature of the drugs by saying “adult neurons don’t form many new synapses.” That is simply not true. The new science is showing that brain health during aging relies on the formation of new synapses."
I really haven't heard much speculation on the growth of new synapses in adult brains. "New synapses" could only form when a brand new nerve cell generates amongst the cluster of older ones, as a 'synapse' is the space between two separate nerve cells. And new nerve cells in adult brains don't occur very often - the most current research restricts neuronal growth in adult brains to very localized regions of the prefrontal cortex, which means that the researchers the article's author attempts to discredit *are* right. If new synapses form only when new nerve cells appear - an uncommon, unpredictable occurrence - then adult neurons certainly don't form many new synapses.
It's also very heavily biased against the pharmaceutical companies, being that the website claims to sell the "world's best nutritional supplements since 1985," so it makes perfect sense they want to discredit the safety of prescription medications. It is interesting, though, that they happened to target Lyrica and Neurontin with this one.
But. Sorry to go off. It irritates me when some shit-for-brains writer with a hidden agenda presents, as facts, moronic and unsubstantiated claims to the public.
Also, Cane, bravo for posting that abstract and PR. Just reading the press release re-taught me a whole shitload about synaptogenesis (been a few years since college and clinical neuropsychology lol); I especially liked this part:
"Barres noted that he and his colleagues found that gabapentin does not dissolve pre-existing synapses, but only prevents formation of new ones. That greatly diminishes gabapentin’s potential danger to adults. In mature human brains, astrocytes ordinarily produce very little thrombospondin, and adult neurons don’t form many new synapses, although some new synapses do continue to be formed throughout life — for example, in a part of the brain where new memories are laid down and at sites of injury to neurons, such as occurs after a stroke."
I wonder if this paragraph provides implications for the idea that chronic use of either gabapentin or pregabalin may permanently impair memory encoding in adults when a multiple-year model of study would be used. I'm 25, and it's difficult to gage where an adolescent brain becomes an 'adult' brain - thus signaling the end of major new synaptogenesis and tissue plasticity in the brain. The short-term deficits in memory that I, and almost every other lyrica user here, have complained about must be caused by a2-d1 activation, but at the same time, it isn't the synapses that are being affected. Or maybe they are, in another in/direct manner. I dislike being the guinea pig, but nevertheless, THANK YOU for the wonderful abstract and press release!!!!
