What is PBA? This stands for PseudoBulbar Affect which causes certain individuals to experience sudden, frequent, and uncontrollable episodes of exaggerated crying and/or laughing. And now there is Nuedexta with Dextromethorphan/Quinidine available as the first and only treatment that is approved for treating those with PBA. While there is no cure for PBA, Nuedexta was shown to reduce PBA episodes by 44 % by the end of the 1st week of a 12-week trial. So ask your doctor about an Rx for Nuedexta to help you with the unpredictable episodes you are experiencing that have you feeling so frustrated and misunderstood.
