Foix-Thevenard Symptom

Foix-Thevenard symptom is a medical term that describes an unusual phenomenon in neurology. This symptom was described by French neurologists Charles Foix and Albert Thévenard at the beginning of the 20th century.

The Foix-Thevenard symptom is characterized by the patient experiencing a sensation of a push or blow in the head when he suddenly raises his head from a lying or sitting position. This phenomenon can occur both with the normal position of the head and when it is tilted forward or backward.

This unusual phenomenon was named after two French neurologists who described it in their papers. It was first described in 1908, but received its name only in 1930.

The causes of the foie-Thevenard symptom are not fully understood. However, there are several hypotheses to explain its appearance. One of them is associated with changes in the functioning of the vestibular and auditory apparatus with a sharp change in head position. Another hypothesis suggests that this phenomenon may be associated with disruption of the cerebellum and motor coordination.

It is important to note that the foie Thévenard symptom is not a disease and does not require treatment. It can occur in healthy people, as well as in patients with various neurological diseases. However, if this phenomenon bothers the patient and causes discomfort, then a consultation with a neurologist may be required to determine the cause and prescribe treatment, if necessary.

FOE-TEVENAR SYMPTOM

Foix-Thevenard symptom is one of the clinical signs of myoclonic psychosis. It manifests itself as a sudden contraction of the facial muscles, which appears after a pause and resembles a sigh or a wave of the hand with a sharp exclamation expressing surprise. It differs from other myoclopastic symptoms in that it occurs abruptly, independently and suddenly stopping, and is not accompanied by vegetative disorders, vomiting or vegetative crisis. During attacks, typical movements are usually performed clearly and correctly, sometimes spontaneously
