The pathophysiological mechanisms of primary dystonia have largely remained obscure. Yet there is one undeniable observation: lesioning or high-frequency stimulation of the internal segment of the globus pallidus (GP) ameliorates dystonic symptoms. The latter observation implicates abnormal pallidal activity in the genesis of primary dystonia. Recently, excessive oscillatory pallidal activity i...
Genetic variants of the SLC6A3 gene that encodes the human dopamine transporter (DAT) have been linked to a variety of neuropsychiatric disorders, particularly attention deficit hyperactivity disorder. In addition, the homozygous Slc6a3 knockout mouse displays a hyperactivity phenotype. Here, we analyzed 2 unrelated consanguineous families with infantile parkinsonism-dystonia (IPD) syndrome and...
In recent years, intrathecal baclofen (ITB) has attained an important role in the treatment of severe spasticity and dystonia in children. There are principal differences between the use of ITB in children and its use in neurology and oncology in adults. Here, we present a consensus report on best practice for the treatment of severe spastic and dystonic movement disorders with ITB. Using a pro...
Classical rate-based pathway models are invaluable for conceptualizing direct/indirect basal ganglia pathways, but cannot account for many aspects of normal and abnormal motor control. To better understand the contribution of patterned basal ganglia signaling to normal and pathological motor control, we simultaneously recorded multi-neuronal and EMG activity in normal and dystonic rats. We used...
SYNOPSIS Thirty-nine patients with the idiopathic blepharospasm-oromandibular dystonia syndrome are described. All presented in adult life, usually in the sixth decade; women were more commonly affected than men. Thirteen had blepharospasm alone, nine had oromandibular dystonia alone, and 17 had both. Torticollis or dystonic writer's cramp preceded the syndrome in two patients. Eight other pati...
Dystonia has a wide range of causes, but treatment of dystonia is limited to minimizing the symptoms as there is yet no successful treatment for its cause. One of the optimal treatment methods for dystonia is chemodenervation using botulinum toxin type A (BTX-A), alcohol injection, etc., but its success depends on how precisely the dystonic muscle is selected. Here, we reported a successful exp...
Background: A 37-year-old female with a hyperkinetic movement disorder due to chorea–acanthocytosis developed severe painful degenerative arthritis of her left knee as a consequence of repetitive involuntary flexion and extension dystonic and ballistic movements. Case Report: Despite profound limitation in her mobility a total knee replacement was successfully undertaken. Discussion: The case e...
BACKGROUND Acute dystonic reactions following the administration of safe, reliable drugs can occur and must be promptly recognized and treated in the emergency room. PHENOMENOLOGY SHOWN The entire clinical course of an acute dystonic reaction due to metoclopramide, from early motor signs to full-blown clinical symptoms and resolution. EDUCATIONAL VALUE Providing elements for early recogniti...
