Neurology Red Flags and When to Get Help
Warning signs
Red flags
Some neurological symptoms should be treated as urgent. These include sudden weakness, sudden face droop, sudden trouble speaking, severe sudden headache, new seizure, fainting with prolonged confusion, or new loss of vision.

If someone has sudden one-sided weakness, trouble speaking, or facial droop, emergency evaluation may be needed right away.
