New Way to Stimulate Brain to Release Antioxidants 98

Posted by samzenpus from the wired-reflexes-2 dept.
Neopallium writes "A joint research effort between researchers at the Burnham Institute for Medical Research in La Jolla, CA, and a team from Japan (Iwate University, Osaka City University, Gifu University, Iwate Medical University) has discovered a novel way to treat stroke and neurodegenerative disorders. This approach works by inducing nerve cells in the brain and the spine to release natural antioxidants that protect nerve cells from stress and free radicals that lead to neurodegenerative diseases."

      None the less it could be very good for those whom haven't acquired it yet. Let's be honest, even if you get cured for one disease, odds are you are going to get another to which a cure has not yet been discovered. So let's face it, there are more preventative medicines that there are cures. Preventative medicine is sometimes just as good as a cure.

      Not necessarily. If you have an ischemic stroke, some of the tissue will be lost beyond saving and undergo necrosis. There will however be a much larger region, called "the penumbra" (shadow) that will be subjected to a certain degree of ischemic damage. Much of this region will be damaged not by the ischemia itself, but by oxidative stress at reperfusion when blood with oxygen and nutriets starts flowing back into the tissue.

      Much as been tried to limit this reperfusion damage, including calcium channel blockers (e.g. nimodipine) and different antioxidants, but to no great success. You could argue that enhancing your antioxidative capacity before the reperfusion damage appears could limit the extend of damage to your brain. I remain carefully optimistic.
      • Not to mention the fact that many of these diseases such as Alzheimers and Lou Gerhigs disease are slow and progressive, so that if you start showing early signs and are diagnosed, you still have time to take potentially "preventive" medicines to stop any further progression, even if you can't reverse what's already happened.

However, at excessive levels glutamate is toxic, resulting in over stimulation of nerve cells, known as excitotoxicity, and causing excessive stress on the nerve cells eventually ending in cell death."

      • What's your evidence that overstimulation of nerve cells = higher mental capacity? Considering that this overstimulation is occurring in stroke and Alzheimers victims, and their mental capacity (or at the very least their ability to make use of their mental capacity) ultimately plummets, I'd say that's just wild speculation.
        • Normally, glutamate is a neurotransmitter which allows for communication according to TFA. I'm speculating here that less glutamate means less communication (hence slower thinking) and that more glutamate means more communication (better thinking). Just like caffeine enhances mental focus and physical performance, but too much will kill you. As long as you don't have too much glutamate and cross the threshold to where your nerves suffer damage, wouldn't increased amounts lead to better mental performance
          • First, you're making an unproven leap in logic to compare less communication to slower thinking and more communication to better thinking. While it may *seem* like an obvious and logical conclusion, there are many things in the world that seem like they should logically be one way but in reality are the exact opposite. For example, while ritalin is a stimulant, it calms the behavior of people with ADHD. There is of course a logical and scientific explanation for this effect, but from a layman's perspective

    This sounds like protandim. Protandim was a nutritional supplement that was being touted as a life extension drug a while back. The idea was that the human body could never swallow enough anti-oxidants to make up for the fall off with age. Besides, acids in the stomach ruin most anyways. The researcher who made protandim got the idea of restimulating the bodies natural production of anti-oxidants. I believe they claimed a 400% increase in naturally produced anti-oxidant levels. There were quite a few scientific papers that showed beneficial effects to mice suffering from strokes. Unfortunately the company seems to have wavered on what their claims are. Over time, they stepped down from that less provable statement that it could extend lifespan. Still, I don't think anyone has refuted the positive effects. They just shouldn't have targeted the I want to live forever market.

      More likely is that years of smoking pot would make this less necessary. The most current research indicates that cannabanoids (delta-9 tetrahydrocannabinol being chief among them) stimulate processes in the brain that protect against both damage from chronic causes (i.e. Alzheimer's) and acute trauma. A Google search for "Alzheimer's" and "Marijuana" should yield some good starting points. And, pot has the added bonus of probably being much cheaper than any new drug or treatment that the pharmecutical companies are likely to come out with anytime soon. Just remember to fight terrorism and buy domestic.

    However, there have been quite a few promising studies (in both rats and people) showing that antioxidants dramatically reduce the extent of damage to the brain in both diseases of the brain and traumatic brain injury.

Compounds such as alpha-lipoic acid (which is both fat- and water-soluble) and curcumin (a component of the popular curry spice turmeric) are cheap, safe, and very powerful antioxidants that have been studied.
