Abstract
Pseudobulbar affect (PBA) is a disorder that develops in the context of a brain injury or underlying neurological dysfunction. It is characterized as an affective disorder of emotional expression. PBA manifests as frequent uncontrollable outbursts of laughing or crying, incongruent with the individual's internal emotional state. It can be challenging for clinicians to differentiate PBA from mood disorders, contributing to its high rate of misdiagnosis. This lack of recognition leads to ineffective and insufficient treatment, impacting patients' quality of life. The current article provides an overview of PBA, including its history, prevalence, pathophysiology, diagnostic criteria, clinical implications, and treatment.
