If the eye twitches, an "angry nerve" could be responsible
Most people know the symptom "eyelid twitching". If the eye twitches, a blood vessel on the brain "annoyed" a nerve, as the neurologist and senior doctor, Prof. Dr. Wolfgang Jost, from the German Clinic for Diagnostics in the Department of Neurology in Wiesbaden. The occasional flickering of the eyelid muscle occurs when a blood vessel in the brain pulsates because, for example, blood pressure rises due to tiredness, stress or excitement. It can happen that the vessel "touches" a nerve that comes from the brain, according to the doctor.
Annoyed nerves from pulsating blood vessels
According to Jost, the nerve strands directly on the brain are particularly sensitive. A short touch through a pulsating blood vessel is enough to irritate nerves. It can happen that the "annoyed" nerve makes the lower eyelid muscle of the eye twitch. "The occasional restlessness of a eyelid" is nothing special, says the neurologist. It is even possible that the twitching of the eyes lasts for a whole day. Those affected can hardly defend themselves against it, after all, the twitching cannot be suppressed cognitively. Rather, twitching eyes are comparable to falling asleep in the hands or tingling in the fingers when the elbow is pushed somewhere. "You simply annoyed the nerve a lot with pressure," said Jost.
When eye twitching occurs continuously
It is different, however, if the twitching occurs not only on one face, but on several parts at the same time. It is also problematic if the flickering occurs almost daily or more often. In such a case, the symptoms are not the "normal eye twitching" that almost everyone knows, but possibly a neurological disorder. It is conceivable that the patient suffers from a so-called "spasm hemifacialis". This leads to cramping because of a disturbed nerve-vascular contact. The symptoms around the eye often begin and spread over a longer period of time to the entire half of the face. Jost reports that the symptoms are physically harmless for the person concerned, but are often very emotionally stressful because the social environment constantly responds to the patient's twitching eye.
The disease occurs in most cases from the age of 60 and many times those affected suffer from high blood pressure for a long time. According to the doctor, injections of botulinum toxin into the affected muscles are carried out as the therapy of choice. Nothing is changed in the cause, but this can paralyze the muscle for some time. The treatment is carried out every 3 to 5 months. (sb)
