What is torsion dystonia-2?
Summary Torsion dystonia-2 is an autosomal recessive neurologic disorder characterized by onset of symptoms in childhood or adolescence. ‘Dystonia’ is characterized by involuntary, sustained muscle contractions affecting 1 or more sites of the body; ‘torsion’ refers to the twisting nature of body movements observed in dystonia.
What is DYT1 dystonia?
DYT1 dystonia is a rare form of dominantly inherited generalized dystonia that can be caused by a mutation in the DYT1 gene. It typically begins in childhood, affects the limbs first, and progresses, often causing significant disability.
Can dystonia spread to other body parts?
Acquired dystonia often plateaus and does not spread to other parts of the body. Dystonia that occurs as a result of medications often ceases if the medications are stopped quickly. Dystonia can be a symptom of other diseases, some of which may be hereditary. When do symptoms occur?
What is primary generalized dystonia?
Primary generalized dystonia, also referred to as primary torsion dystoniaordystonia musculorum deformans,is caused by a group of genetic disorders with onset in childhood (Fig. 615.2).
What are the Galois cohomology groups?
Galois cohomology groups proved to be specially effective in the problem of classifying types of algebraic varieties. These problems led to the problem of computing the Galois cohomology groups of algebraic groups.
How did Thomas Tate use Galois cohomology in his research?
Tate used Galois cohomology to introduce the concept of the cohomological dimension of the Galois group $G_k$ of a field $k$ (denoted by $ {m cd}\\; G_k$).
What is abelian Galois cohomology?
The general theory of Abelian Galois cohomology groups was then developed by Tate and J.-P. Serre [Se] , [CaFr], [Se3] . Tate used Galois cohomology to introduce the concept of the cohomological dimension of the Galois group $G_k$ of a field $k$ (denoted by $ {m cd}\\; G_k$).
