I would talk specifically to AOA residents to see if they feel this way.
The reason DO residents and DO Neurosurgeons cannot become AANS and CNS members is because the bylaws of the societies state you must be ABNS board eligible or board certified and DO Neurosurgeons are certified through the ACOS. It is a BIG deal to change 50+ year old societies bylaws...
There is no point in spreading rumors and hoopla as the major discussions of what IS this merger haven't been hashed out yet. You should decide yourself if you want to be a neurosurgeon or not.... and stop wasting your time on here.
I guarantee >2 programs will become ACGME that are currently AOA.
