• Weakness

  Prominent pharyngeal weakness and spasticity with difficulty of speech and swallowing. Horizontal and vertical nystagmus, loss of fast saccadic eye movements and impairment of upward gaze. Peripheral neuropathy may occur. [neuroweb.us]

  There is a risk of temporary paralysis of the muscles being injected or the leaking of the toxin into adjacent muscle groups, causing weakness or paralysis in them. [ipfs.io]

  After injection into a muscle, the action of botulinum toxin is to interrupt nerve messages to the muscle, preventing the release of the neurotransmitter acetylcholine, which stimulates muscular contractions, and giving rise to weakness of that muscle [rarediseases.org]

• Nausea

  The clinical features are those of meningoencephalomyelitis and include nonspecific prodromal stage, followed by headaches, nausea, vomiting, behavioral changes, altered state of consciousness and often seizures. [neuroweb.us]

• Vomiting

  Propionic acidemia : This autosomal recessive disorder presents in adulthood with chorea, dementia, seizures and episodes of recurrent vomiting (ketosis and acidosis). [neuroweb.us]

• Myopathy

  Adult-onset acid maltase deficiency is an inherited lysosomal skeletal-muscle disease characterized by progressive myopathy and respiratory failure, for which there is no known therapy [25]. [wikigenes.org]

• Myoclonus

  Surprisingly, pain is not very common in dystonia except in cervical dystonia, in which up to 75% of patients experienced pain in one study. 5 Dystonia can present with tremor (dystonic tremor) or myoclonus (dystonia–myoclonus). [neupsykey.com]

  The phenomenology of these disorders is quite variable encompassing chorea, tremor, dystonia, myoclonus, tics, other dyskinesias, jerks and shakes. [books.google.com]

The injections are not a treatment for the disease, but are a means to control its symptoms. [6] A fourth option in the treatment for the symptoms of torsion dystonia is surgery. [en.wikipedia.org]

Treatment Despite the paucity of knowledge about causes of dystonia, the treatment of this condition has markedly improved, largely as a result of application of deep brain stimulation (BTX). [bcm.edu]

Various treatments focus on sedating brain functions or blocking nerve communications with the muscles via drugs, neuro-suppression, or denervation. All current treatments have negative side-effects and risks. [ipfs.io]

Adult onset IGE shares many features with "classical" IGE, including EEG findings and prognosis, and is likely to represent a genetic epilepsy [31]. [wikigenes.org]

The prognosis is usually bad with survival rates less than a few years after onset. [neuroweb.us]

By etiology Primary (idiopathic) dystonia: may be familial ( Table 5.2 ) 7–30 or sporadic. In the pure dystonic syndromes, dystonia is the main and only clinical sign (except for dystonic tremor). [neupsykey.com]

Notwithstanding a potential role of the NE in the etiology of torsion dystonia, it remains possible that the disease results from altered torsinA interactions with substrates in the peripheral ER. [pnas.org]
