This Common Facial Twitch Holds the Key to a Serious Neurological Clue—Find Out What! Facial twitching is often dismissed as a minor, minor annoyance—something you shrug off as stress or fatigue. But what if this seemingly trivial involuntary movement holds a deeper, more critical meaning? New research and clinical observations suggest that one common facial twitch could offer vital neurological insights and even serve as an early warning sign for serious neurological conditions. ### Why Do Facial Twitches Occur? Facial twitches—such as spasms in the eyelid (myokymia), corner of the mouth (often due to benign fasciculation), or even sudden jerks of the lips—arise from abnormal electrical activity in the nerves controlling facial muscles. While occasional twitching is usually harmless and linked to stress, caffeine, or minor muscle fatigue, persistent or irregular twitching may signal underlying neurological changes.
