What is used to diagnose pseudobulbar affect?

ANSWER

Your doctor won't need to do tests to diagnose pseudobulbar affect (PBA). But to rule out a form of epilepsy that can cause similar symptoms, he or she might order an electroencephalog, a painless test that tracks your brain waves. Two questionnaires help determine if the laughing and weeping are signs of PBA:

  • Pathological Laughing and Crying Scale: The doctor asks you questions about the episodes, including how long they lasted, how they related to your mood and social situation, and how much distress you felt afterward.
  • Center for Neurologic Study-Lability Scale: You answer questions about your symptoms. How often do they occur? How do they make you feel? For example, "I find myself crying very easily," or, "I'm easily overcome with laughter."
