Focal Neurological Deficits
Alternate Names : Neurological Deficits - Focal
Definition
A focal neurologic deficit is a problem in nerve function that affects either:
- a specific location -- such as the left face, right face, left arm, right arm, left leg, right leg, even just a small area such as just the tongue
- a specific function (for example, speech may be affected, but not the ability to write)
The problem occurs in the brain or nervous system. It may result in a loss of movement or sensation. The type, location, and severity of the change can indicate the area of the brain or nervous system that is affected.
In contrast, a non-focal problem is NOT specific -- such as a general loss of consciousness.
