PBA is a condition characterized by episodes of uncontrollable laughing and/or crying that may be inappropriate, unrelated to the situation at hand, or not expressing the person's mood. The condition is known by other terms, including emotional lability, emotional incontinence, and pathological laughing and crying.

If you or someone you know experiences episodes of uncontrollable laughing and/or crying, you may be eligible to participate in a clinical study now underway to find a treatment for pseudobulbar affect (PBA).
