If you have uncontrollable frequent crying or laughing look into pba and nudexta to treat it with your Neurologist, I had frequent uncontrollable crying for years and thought it was just me with this ms and for years doctors just told me I need to talk to someone. I saw an ad about Pseudobulbar affect (PBA) and there was a questionnaire you can take then bring it to your doctor, I tried with my doctor at the beginning (2012) but it got brushed off saying I didn't have it, fast forward to now My current neurologist listened to my issue and told me It sounds exactly like PBA and prescribed NUDEXTA which treats it specifically. I was soo freaking happy, once I started it I immediately felt better and still do, it's a major relief!
