Do I have PBA?

You could have Pseudobulbar Affect (PBA) if you…

  • Have been diagnosed with a brain injury or neurologic condition
  • Experiencing sudden, frequent, uncontrollable crying and/or laughing

If this applies to you, take the first step in learning if your symptoms could suggest PBA by completing the PBA Quiz. (This quiz is not a diagnostic tool. Only a healthcare professional can determine whether you have PBA.)

The PBA Quiz

Could you or someone you care for have Pseudobulbar Affect (PBA)?

PBA can happen in people with a brain injury or certain neurologic conditions. Take this 7-question quiz to help determine if you or your loved one is experiencing symptoms that could suggest PBA.

Eligible participants will have access to multiple resources once they receive their results, including the opportunity to participate in PBA Nurse Talk*.


The PBA Quiz is based on the Center for Neurologic Study-Lability Scale (CNS-LS). This assessment was developed by healthcare professionals to help doctors determine whether a person is having PBA symptoms. It has been validated in ALS (Amyotrophic Lateral Sclerosis) and MS (Multiple Sclerosis) patient populations. The PBA Quiz is not a diagnostic tool and is not intended to substitute professional medical assessment and/or advice. Only a healthcare provider can diagnosis PBA.

*PBA Nurse Talk is sponsored by Avanir Pharmaceuticals, Inc., which is committed to supporting those who may be suffering from PBA. This program is offered at no cost to those eligible, does not require health insurance, and does not replace speaking with a healthcare provider – only a healthcare provider can diagnose PBA. PBA Nurse Talk conversations will remain completely confidential. PBA Nurse Talk is only available to people experiencing uncontrollable crying and/or laughing, not their caregivers.
