Yesterday I was talking to a recovering toxic mold victim. She brought up the idea that a drug called Namenda has been really helpful for her in terms of cognitive focus and energy. This is a glutamate blocker used for Alzheimer's. Has anyone here tried this drug? Does anyone have any comments about it? This person was fairly sick for a number of months after her mold exposure, but never actually had CFS. She's recovering well in a super-pristine house in rural Colorado. A comment from Dr. Amy Yasko is below. She says in another post that the idea of using this drug in children concerns her especially. Thanks for your comments! Best, Lisa * While I think that memantine has the potential to be a real positive in some instances, it also makes me a bit nervous. I think that I would reserve the use of memantine on a regular basis unless you had no other way to control excitotoxin damage. For those of you who do not know what we are talking about, memantine is new prescription medication that blocks activity at the NMDA glutamate receptor. It has shown some early promising results for Alzheimer's disease. It should be able to halt excitotoxin damage; however, it may also block neurotransmission that you do want to see. It is supposed to be a reversible blocker; however I have some concerns in that direction. I think it is worth considering for diseases like ALS or severe Alzheimer's however it does leave me concerned about trying it for autism , especially until there is more data on it to be certain that it's blocking ability really is completely reversible.
