Are There Tests to Diagnose the Cause of a Labile Affect?
There are no tests to directly diagnose a labile affect.
However, routine testing may be done to determine an underlying cause, such as a brain injury.
Pseudobulbular affect (PBA) is diagnosed using history, mental status examinations, and neurological testing.
However, for many people, symptoms significantly interfere with daily life.
Treatment for a labile affect can include medications and therapy.
Medications
Medications are generally targeted to any underlying condition that might be contributing to a labile affect.
It may also affect their ability to work, perform daily tasks, or maintain personal relationships.
If you or a loved one are in immediate danger, call 911.
