It’s hard to understand if you don’t know that it could be Pseudobulbar affect (PBA) – a neurological condition involving involuntary, sudden, and frequent episodes of laughing or crying.
Two million people in the U.S. know they have PBA, but more than 9 million are estimated to be living with the condition.*
53 percent of stroke survivor respondents report symptoms of PBA, but fewer than 1 in 5 know about PBA.
Awareness, education, and treatment can help people better manage PBA in everyday life. Find information and resources to help.
Pseudobulbar Affect Voices (PBA Voices) is dedicated to building awareness of PBA and to helping providers diagnose, track, and treat the disease. Learn more today.
*When considering patients with any of 6 common neurologic conditions associated with PBA, it is estimated that 37%, or an estimated 7.1 million Americans, have symptoms suggestive of PBA as defined by a CNS-LS (Center for Neurologic Study-Lability Scale) score ≥13 and 9.4% of patients, or an estimated 1.8 million Americans, with CNS-LS scores ≥21. The presence of PBA symptoms was defined as a CNS-LS score ≥13 and a more restrictive definition was also evaluated using CNS-LS ≥21. The CNS-LS was validated as a PBA screening tool in ALS and MS populations. A CNS-LS score ≥13 merits further diagnostic assessment.
