Talk to your doctor about managing PBA
PseudoBulbar Affect (PBA) is a real condition with its own symptoms—and there’s help.
Getting an accurate diagnosis is key
Because PBA always happens with certain neurologic conditions or brain injury, its symptoms are often misunderstood. Sudden, frequent, uncontrollable crying or laughing from PBA can be mistaken for other states or conditions, such as:
- Depression

- Bipolar Disorder
- A disorder associated with mood swings
- Euphoria
- Excessive laughter sometimes associated with conditions like multiple sclerosis (MS)
- PTSD
- (post-traumatic stress disorder) – A disorder that follows a traumatic event, sometimes associated with conditions like traumatic brain injury (TBI)
- Pain
- A feeling sometimes communicated through crying, especially in people with Alzheimer’s disease
It is possible to have any of these symptoms while having PBA. Each condition should be diagnosed and managed by a doctor.
Only your doctor can diagnose PBA. That's why it's important to give a full picture of your laughing and/or crying episodes —including how often they occur and their impact.
