SILVA, Ana Isabel; MASSANO, João; SIMOES-RIBEIRO, Fernanda    ROSAS, Maria José. Post-Traumatic Cervical Dystonia and Atypical Dystonic Tremor. []. , 21, 5-6, pp.151-153. ISSN 2183-2447.

Post-traumatic cervical dystonia is a rare manifestation after head trauma. The authors describe the clinical case of a patient with cervical dystonia and involuntary movements like dystonic tremor that appeared after a head trauma. The relationship between trauma and development of involuntary movements is difficult to prove, mainly in the presence of normal brain imaging studies. The trauma may be a triggering factor for cervical dystonia in individuals with genetic susceptibility. Some patients with focal dystonia exhibit a moderate postural tremor of the superior limbs. Nowadays, there are no biological markers, so it is difficult to determine if the postural tremor is part of the focal dystonic syndrome or if it reflects the presence of both, focal dystonia and essential tremor.
