premorbid functioning
Cognitive and functional abilities that existed before onset of brain injury or neurological condition.
Full Definition
The level of intellectual, academic, occupational, and social functioning that an individual possessed prior to developing a neurological condition or sustaining brain injury. Estimating premorbid functioning is crucial for determining the extent of decline and setting realistic rehabilitation goals. Methods include reviewing educational/occupational history, using hold tests like vocabulary measures, and applying regression-based formulas.
Usage
