Christian, like mario said, there are no tests FOR BFS or BCFS. They test for the bad stuff and make a diagnosis from there. You can't test for something that doesn't exist. BFS "exists" but not "clinically" in the fact that there is no set of markers to test for. All you can do is test for tangible things and rule out the bad stuff from there. Just because you didn't "twitch" or "cramp" during the exam doesn't mean by ANY stretch of the imagination that they "missed" something. You are forgetting a couple of VERY important facts. 1) When they perform an EMG they aren't looking for "twitches". They are looking for dirty conductivity, spikes, etc. in your nerve electrical pathways. 2) Twitches caused by an honest to goodness neurological problem aren't the CAUSE of the problem, they are a symptom OF that problem. If there is no evidence of a problem, then obviously it isa benign condition, AND... if it was indeed a serious condition and you were already having twitches and other symptoms, then that would mean the disease is already running its course and would indeed show up on tests, as weakness, as atrophy, etc. Keep in mind, twitches in ALS are SECONDARY! They happen AFTER nerves have already begun dying and disconnecting. If you have colon cancer and you get uncontrolled bowels from time to time, if it is a day where you saw the doctor and you didn't have a bowel issue, is the colon cancer gone that day? Heck no! If you have a brain tumor that causes headaches, and when you go see the neuroologist you don't happen to have a headache at that moment, does that mean the brain tumor disappeared at that moment in time or won't show up in a brain scan? Heck no! If you had a serious condition, they don't look at secondary symptoms to make a diagnosis they look for the actual problem and make a diagniosis from there. For one, in ALS the TYPES of twitches, HOW they present themselves and how the cramps present themselves are all completely different and are happening for ENTIRELY different reasons than those of a benign condition. ALS and BFS twitches don't look the ame, they don't feel the same, and they don't present like each other. I, and other "experts" on here have said this so many times we're turining blue in the face! I don't know how many times we'll have to keep saying it.If you had a "real" disease, such as ANY of the honest to goodness muscle or neurological diseases, they don't come and go. They "symptoms" may come and go, or at least the NOTICABLE symptoms might, but the disease is ALWAYS there! You may have good days and bad days BUT, the fact that the DISEASE is still there REGARDLESS of the secondary symptoms still remains. With ALS, you may not twitch but the disease is still there running its course. With a brain tumor or any type of typical cancer, the tumor is still there growing and doing its thing but the secondary symptoms may come and go. It doesn't mean that the tumor will suddenly disappear in an X-Ray just because that day you weren't experiencing any usual symptoms.I don't know how many times we have to say this on here folks. A clean EMG means no disease!!Twitches are meaningless in diagnosing a disease. Cramping or "perceived" cramping is meanigless in diagnosing a disease. Twitches caused by ALS and BFS are COMPLETETY different from each other. How many clean EMG's and BFS diagnosis' do you need to get before you realize (or believe) that you have NO DISEASE? Our brains and nervous system have a billion more times the wires and "circuitry" than the best of the best computers of today. How many times do computes get unexplained glitches where they do something that isn't a virus, isn't a hardware or software problem yet it freezes or locks up, functions oddly, has to reboot, etc? Don't you think our own circuitry in our bodies can "glitch" from time to time? This rings especially true with age. It doesn't have to be a "disease" to function oddly or do something off kilter than the average other part of the population, but the fact of the matter is; some of us DO have a minor wiring issue that causes us to "glitch", and just like that computer glitch that can come and go... so can our glitches. You don't have to have a "diagnosis" to explain everything. You don't appear to have a "disease", the tests back that up so just accept the fact that your computer functions a little more oddly than most other people's and learn to deal with it like the rest of us do. Unlike a computer, you can't go out and buy a brand new one everytime your body gets a glitch. Luckily our bodies do a self diagnosis of themselves and can fix themselves under most circumstances. It doesn't have to be a life threatening circumstance for it to NOT be able to fix itself. BFS. BCFS and MANY other NON life threatening ailments are also included in that bunch.
