TUBB4a is supposed to be involved in neuronal cytoskeletal defects ( Hersheson et al., 2012 ), while ANO3 and GNAL mutations point to a key role for striatal neurons in the pathophysiology of dystonia, either through abnormal neuronal excitability related [frontiersin.org]

Clinical Context: Large neutral amino acid absorbed in proximal small intestine by saturable carrier-mediated transport system. Meals that include other large neutral amino acids decrease absorption. [misc.medscape.com]
Treatment
It is clear that as long as the cerebellum's role in dystonia genesis remains unexamined, it will be difficult to significantly improve the current standards of dystonia treatment or to provide curative treatment." [20] Treatment [ edit ] Reducing the [wikivisually.com]
Although no curative treatment for dystonia is available, treatment of the underlying disorder may help reverse symptoms in patients with secondary forms of dystonia (eg, from Wilson disease or DRD). [misc.medscape.com]
Together with the loss of S-CRMs, other valuable materials, such as gold or copper, are lost within those output fractions as well, due to limited liberation and separation techniques in mechanical treatment. [encore.seals.ac.za]
Prognosis
[…] abstract structured in up to 10 sections: Definition of the disease – Epidemiology – Clinical description – Aetiology – Diagnostic methods – Differential diagnosis - Genetic counseling (if relevant) – Antenatal diagnosis (if relevant) – Management – Prognosis [doczz.fr]
For both symptomatic and non-symptomatic gene mutation carriers, knowledge about the genetic status may have implications for the prognosis and therapeutic management decisions and with respect to family planning. [neupsykey.com]
It can be proposed at the initial phase of the disease to limit the functional consequences and to improve the prognosis for functional recovery. [misc.medscape.com]
The prognosis is usually poor 2,16. Tremor and Dystonia Dystonia may erroneously be interpreted as tremor. Dystonic tremor is frequently misdiagnosed as essential tremor or Parkinson disease. [docplayer.net]
Etiology
ETIOLOGY The etiology of primary dystonia is assumed to be a complex combination of intrinsic metabolic properties, environmental and genetic factors 27,28. [docplayer.net]
Secondary dystonia includes a heterogenous group of etiologies including inherited (with and without brain degeneration) and acquired neurologic disorders. [misc.medscape.com]
The two main axes of classication currently considered most relevant are clinical and etiological [4]. [docslide.net]
These historical reports usually attributed the etiology of the motor abnormalities to overuse. [en.wikipedia.org]
Epidemiology

Pathophysiology
PATHOPHYSIOLOGY CONT.. 1. Lack of reciprocal inhibition by striatum and co- contraction of antagonist overflow 2. Grasping pattern of impulse in EMG 3. [vdocuments.net]
Moreover, these findings may shed light on pathophysiological mechanisms underlying primary dystonias. [frontiersin.org]
Pathophysiology The pathophysiology of dystonia lies in the basis of lack of inhibition. Basal ganglia filter and modulate inputs to improve the precision of fine movements. [docplayer.net]
