So I have a bit of an oddball question. I was diagnosed a few years back with multiple sclerosis after having some vision issues. Thankfully I got connected with a great neurologist at Yale and we have it under control with medicine and an MRI every 6months to watch for progression. I had a follow up visit yesterday and one of the issues we discussed was word finding. Not often but more so over the past 6 months I have found myself having trouble finding a specific word when speaking. Think of it like when the word is on the tip of your tongue but you just can’t think of it. My no neurologist believes it may be related to MS but since it is just a minor issue right now we are going to monitor and see if it progresses. She was recommending that I go get a cog screen test done just to set a baseline so if it were to progress there would be a base to compare it to. This has me worried as it seems like this type of test can bring up all sorts of things the FAA doesn’t like. Right now I have a PPL but have been flying under sport Pilot as my plane and another I use for training all fit under the LSA rules. I don’t ever think I will get back to having a 3rd class medical but my last one was new enough that I could technically qualify for basic med if I ever tried to peruse that route. My question is what concerns should I have with taking a cog screen test not mandated by the FAA. Does the FAA look at them and the results like a hard diagnosis or only in the context of being combined with other issues. This is something my neurologist is recommending but not requiring. I can see her view where it would be beneficial to track MS progress years down the road but also don’t want to screw myself out of being able to fly under LSA or Basic Med just for a good to have type of test.
