The rates of spontaneous remission and progression of dystonia to other sites were studied in 72 patients who first presented with adult-onset torticollis, and who were followed up for a mean of 7.7 years. Dystonia had progressed to sites other than the neck (mainly the face and upper limbs) in 23 patients (32%). The latter cases were not differentiated(More)
We review the existing literature on the involuntary facial movement disorders-benign essential blepharospasm, apraxia of eyelid opening, hemifacial spasm, and aberrant facial nerve regeneration. The etiology of idiopathic blepharospasm, a disorder of the central nervous system, and hemifacial spasm, a condition involving the facial nerve of the peripheral(More)
Twenty-three children (aged less than 18 years) and 17 adults with severe widespread dystonia were treated with high doses of benzhexol (up to 130 mg daily introduced slowly over many weeks). Children tolerated higher doses (median 30 mg/day) than adults (median 20 mg/day). 52% of the children gained useful benefit, many (43%) without unwanted side effects.(More)
OBJECTIVE To study the sequence of occurrence of REM-sleep behaviour disorder (RBD) and dementia and their frequency among a population of patients with idiopathic Parkinson's disease (PD). METHODS We performed a cross-sectional study on 65 PD patients seen in a movement disorder clinic and their bed partner, and asked them to complete the validated Mayo(More)
Pharmacokinetic studies in parkinsonian patients and healthy volunteers have shown that Madopar HBS behaves as a slow-release formulation of L-dopa and benserazide. In comparison with standard Madopar the rate of absorption is reduced, providing lower peak concentrations of L-dopa. The drug is released and absorbed over a period of 4-5 h, thus maintaining(More)
Anterior and posterior sagittal shift of the head are less common postures in cervical dystonia and, as such, have not been comprehensively studied. In this article, we have detailed both our clinical and electromyography (EMG) findings in 11 patients with prominent dystonic sagittal shift of the head. A new technique of injection of the longus colli, based(More)
PURPOSE This study characterizes the linear relations among knee strength, work capacity, and lower- and higher-intensity measures of functional performance in ambulatory, high-functioning older adults. METHODS Sixty-two seniors (average age = 73.4 +/- 7.3 yr) participated in the study. Isokinetic measures included the peak flexion/extension torque(More)
The short-term efficacy of continuous intravenous infusions of levodopa (with oral peripheral decarboxylase inhibitor) in abolishing or reducing "on-off" fluctuations in patients with Parkinson's disease is well established. However, there are suggestions that clinical response may be less good with longer infusions, or infusions on consecutive days. We(More)
