had Huntington's chorea, two athetosis, two dystonia musculorum deformans, one hemiballismus, and one spasmodic torticollis. Four of the eight improved patients have continued taking the drug for longer than six months. In a second study seven patients with Huntington's chorea were treated for two weeks each with tetrabenazine (50 mg t.d.s.) and with amantadine (100 mg t.d.s.) and the results assessed by the same method. The choreiform movements of six of these patients were strikingly improved (...) with tetrabenazine therapy, but amantadine had no effect. Tetrabenazine is an effective agent for the suppression of choreiform and ballistic involuntary movements. It is only slightly effective in the treatment of athetosis and spasmodic torticollis. Drowsiness, insomnia, and depression were the most conspicuous unwanted effects, and these may limit the clinical usefulness of the drug.

-Minute Neurologic Exam SOCIAL MEDIA Add to Any Platform Loading Topic Resources Dystonias are sustained involuntary muscle contractions of antagonistic muscle groups in the same body part, leading to abnormal posturing or jerky, twisting, intermittent spasms that can resemble tremors, athetosis, or choreoathetosis. Dystonias can be primary or secondary and can be generalized, focal, or segmental. Diagnosis is clinical. Botulinum toxin injections are used to treat focal or segmental dystonias

: Regional Dissection 3D Model Basal ganglia Classification Movement disorders are commonly classified as those with Decreased or slow movement (hypokinetic disorders) Increased movement (hyperkinetic disorders) The classic and most common hypokinetic disorder is Hyperkinetic disorders refer to (including hemiballismus [rapid chorea] and athetosis [slow chorea]) However, this classification does not account for overlap between categories (eg, tremors that occur in Parkinson disease). Cerebellar disorders (...) are sometimes considered hyperkinetic disorders. Hyperkinetic disorders (see figure and see table ) can be Rhythmic Nonrhythmic Rhythmic disorders are primarily tremors—regular alternating or oscillatory movements, which can occur mainly at rest, while maintaining a position, and/or during attempted movement. However, in some cases, a tremor, though rhythmic, is irregular, as occurs when tremor is associated with dystonic disorders. Nonrhythmic hyperkinetic disorders can be Slow (eg, athetosis) Sustained

Differential diagnosis CP should be differentiated from progressive hereditary neurologic disorders and disorders requiring surgical or other specific neurologic treatments.

. These types of hyperkinetic movements can be further classified into two groups. The first group, hereditary ataxias, affect the cerebellum and spinal cord and are passed from one generation to the next through a defective gene. A common hereditary ataxia is . in contrast, sporadic ataxias occur spontaneously in individuals with no known family history of such movement disorders. Athetosis [ ] is defined as a slow, continuous, involuntary writhing movement that prevents the individual from maintaining (...) a stable posture. These are smooth, nonrhythmic movements that appear random and are not composed of any recognizable sub-movements. They mainly involve the distal extremities, but can also involve the face, neck, and trunk. Athetosis can occur in the resting state, as well as in conjunction with and . When combined with chorea, as in , the term "choreoathetosis" is frequently used. Chorea [ ] is a continuous, random-appearing sequence of one or more discrete involuntary movements or movement fragments

that are due to restricted movement in the oral-facial muscles. There are three major types of dysarthria in cerebral palsy: spastic, dyskinetic (athetosis), and ataxic.

Children with cerebral palsy are at risk of learned helplessness and becoming passive communicators, initiating little communication. Early intervention with this clientele, and their parents, often

Definition and classification of hyperkinetic movements in childhood. Hyperkinetic movements are unwanted or excess movements that are frequently seen in children with neurologic disorders. They are an important clinical finding with significant implications for diagnosis and treatment. However, the lack of agreement on standard terminology and definitions interferes with clinical treatment and research. We describe definitions of dystonia, chorea, athetosis, myoclonus, tremor, tics (...) , and stereotypies that arose from a consensus meeting in June 2008 of specialists from different clinical and basic science fields. Dystonia is a movement disorder in which involuntary sustained or intermittent muscle contractions cause twisting and repetitive movements, abnormal postures, or both. Chorea is an ongoing random-appearing sequence of one or more discrete involuntary movements or movement fragments. Athetosis is a slow, continuous, involuntary writhing movement that prevents maintenance of a stable

results from mutation in the gene for the enzyme hypoxanthineguanine phosphoribosyltransferase (HPRT); patients have hyperuricemia, gout, urinary tract calculi, and nephropathy which are effectively treated with allopurinol. There is also a syndrome of dystonia, chorea and athetosis, as well as involuntary self mutilative biting and aggression toward their caretakers, for which there is no treatment.

The latency, the period between the start of treatment and neurological deterioration, was 4,75 +/- 2,55 days (range: 1-10 days). All patients died 17 +/- 14,7 days (range: 1-42 days) after becoming symptomatic. Three of them died shortly after neurological deterioration. Five patients developed a neurological "tableau" with global aphasia. Three patients showed clinical improvement after

Most (83%) children with cerebral palsy have abnormal neuroradiological findings, with white matter damage the most common abnormality. Combined gray and white matter abnormalities are more common among children with hemiplegia; isolated white matter abnormalities are more common with bilateral spasticity or athetosis, and with ataxia; isolated gray matter damage is the least common finding. About 10% of cerebral palsy

In a majority of cases, the predominant motor abnormality is spasticity; other forms of cerebral palsy include dyskinetic (dystonia or choreo-athetosis) and ataxic cerebral palsy. In preterm infants, about one-half of the cases have neuroimaging abnormalities, such as echolucency in the periventricular white matter or ventricular enlargement on cranial ultrasound.
