However, in one case, after a year of shunt placement, the patient switched from forward-back bobbing to side-to-side swaying. There was no discernible reasoning for the switch found. A hypothesis emerged from this case that cerebellar malformations themselves can cause bobble-head doll syndrome. [1]
Rhythmic movement disorder (RMD) is a neurological disorder characterized by repetitive movements of large muscle groups immediately before and during sleep often involving the head and neck. It was independently described first in 1905 by Zappert as jactatio capitis nocturna and by Cruchet as rhythmie du sommeil. [1]
Gradual onset can begin with the manifestation of a hoarse voice quality, which may later transform into a voice quality described as strained with breaks in phonation. [6] These phonation breaks have been compared to stuttering in the past, but there is a lack of research in support of spasmodic dysphonia being classified as a fluency disorder ...
Motor tics are movement-based tics affecting discrete muscle groups. [4]Phonic tics are involuntary sounds produced by moving air through the nose, mouth, or throat. They may be alternately referred to as verbal tics or vocal tics, but most diagnosticians prefer the term phonic tics to reflect the notion that the vocal cords are not involved in all tics that produce sound.
Hemifacial spasm (HFS) is a rare neuromuscular disease characterized by irregular, involuntary muscle contractions on one side (hemi-) of the face (-facial). [1] The facial muscles are controlled by the facial nerve (seventh cranial nerve), which originates at the brainstem and exits the skull below the ear where it separates into five main branches.
Benign fasciculation syndrome (BFS) is characterized by fasciculation (twitching) of voluntary muscles in the body. [1] The twitching can occur in any voluntary muscle group but is most common in the eyelids, arms, hands, fingers, legs, and feet. The tongue can also be affected. The twitching may be occasional to continuous. [2]
The twitching of the right eye could be seen as a heightened sensitivity to energies and a potential awakening of one's intuition. Some believe that it signifies an opening of the third eye.
A tremor is an involuntary, [1] somewhat rhythmic muscle contraction and relaxation involving oscillations or twitching movements of one or more body parts. It is the most common of all involuntary movements and can affect the hands, arms, eyes, face, head, vocal folds, trunk, and legs. Most tremors occur in the hands.
