Focal neurological symptoms

A focal neurologic symptom is a problem that affects either:
  • A specific location - such as the left face, right farm or even just a small area such as 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. 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.
