We describe a 48-year-old woman with putaminal gliosis and a sphenoid wing meningioma at the left, who developed dystonia restricted to cervical regions. We propose the following causal chain: the meningioma led to an occlusion of a lenticulo-striatal branch of the middle cerebral artery that caused ventral putaminal ischemia and finally resulting in symptomatic dystonia. The previously reporte...

BACKGROUND: Dystonia of the eyelids often spreads to affect other muscles in the craniocervical region. Certain blepharospasm-plus subphenotypes may be clinically unique. METHODS: Seven subjects with the subphenotype of late-onset blepharospasm with apraxia of eyelid opening and cervical dystonia with predominant anterocollis were identified from a database of over 1800 patients with primary d...

Dear Editor, Dystonia is a movement disorder characterised by sustained muscle contractions, repetitive twisting movements, and abnormal postures of the trunk, neck, face, or arms and legs.1 Classifi cation of this condition may be based on topography, age at onset, cause, or by the presence of genetic markers.1 When unaccompanied by other neurologic abnormalities, and in the absence of known c...

Dystonic head tremor is known to be a feature in some patients with DYT1 mutation. However, isolated tremor of the head without relevant cervical dystonia has rarely been described. We report here a patient with the three-bp GAG deletion in the DYT1 gene (904_906delGAG) who had severe head tremor in the frame of a generalized limb dystonia.

Our previous study of whiplash injury found that abnormalities in the cervical muscles cause autonomic dystonia. Further research has found that abnormalities in the cervical muscles cause headache, chronic fatigue syndrome, vertigo, and dizziness. We named this group of diseases cervical neuro-muscular syndrome. Patients treated within a 2-year period from April 1, 2002 to March 31, 2004 repor...

BACKGROUND Spasmodic torticollis refers to involuntary dystonic movements of the head that may be associated with certain body and neck positions. The pathophysiology of dystonia is not fully known. CASE REPORT We report a case of torticollis that was unusual in the sense that it occurred only when the patient was lying on one side. DISCUSSION The cause of the cervical dystonia in this pati...

We occasionally observe long-term remission of cervical dystonia after several botulinum toxin treatments. However, botulinum toxin transiently acts on neuromuscular junctions. We herein report that a cervical dystonia patient with spinocerebellar ataxia type 1 could have long-term remission as a result of the depression of hypermetabolism in the bilateral putamen and primary sensorimotor corte...

Cervical dystonia is characterized by involuntary, abnormal movements and postures of the head and neck. Current views on its pathophysiology, such as faulty sensorimotor integration and impaired motor planning, are largely based on studies of focal hand dystonia. Using resting state fMRI, we explored whether cervical dystonia patients have altered functional brain connectivity compared to heal...

Ataxia-telangiectasia-like disorder 1 (ATLD1) is a rare neurodegenerative associated with early onset ataxia and oculomotor apraxia. The genetic determination of ATLD1 mutation in the MRE11 gene (meiotic recombination 11 gene), which causes DNA-double strand break repair deficits. Clinical features patients resemble those telangiectasia (AT), slower progression milder presentation. Main symptom...

BACKGROUND Overuse or task-specific dystonia has been described in a number of professions characterized by repetitive actions, typically affecting the upper extremities. Cervical dystonia (CD), however, has rarely been associated with overuse. CASE REPORT We present a case report of typical CD that developed in the context of chronic repetitive movements associated with the patient's profess...
