PBA Assessment

If you or someone you care for have an underlying neurologic condition or brain injury and are experiencing uncontrollable outbursts of crying or laughing, these episodes may be signs of PseudoBulbar Affect (PBA). Take this short assessment and share the results with your doctor. Simply answer the 7 questions and add up your score. If it’s 13 or higher, that may suggest that you are having PBA symptoms. This assessment tool is not intended to substitute for professional medical assessment and/or advice. Please share your results with your doctor.

 

The PBA assessment was developed by healthcare professionals and is called the Center for Neurologic Study-Lability Scale (CNS-LS). A CNS-LS score of 13 or higher may suggest PBA symptoms and should be discussed with your doctor.
