I just read an article that mentioned MG. It did not say a lot but it did confirm the difficulty in making the diagnosis. It said that most of the neurologists have rarely seen anyone with it. It also stated that the standard “tensilon test” is unreliable in Anti-MuSk Ab+ MG patients. In most of these cases, the MG antibodies are not present or they don't show up in currently available tests. It is commonly misdiagnosed and is reported to only occur in a few like say a 10 people per million.
Now this explains why we face so much lack of awareness about it and people are just not ready to accept and believe even if there is no greater truth than it. Support the ones with such kind of conditions. It is not going to change the bitter truth of their suffering if the society chooses to “NOT ACCEPT” it’s existence. You believe it or not it is for real !!

Do not make life more difficult for them they are already having a hard time. By not accepting you are increasing the already prevalent social stigma associated with such conditions.
Be compassionate.
Be considerate.
