OBJECTIVE To identify the presence of vestibulo-ocular arreflexia in patients with Machado-Joseph disease (MJD), which can easily be diagnosed at the bedside. METHODS Seven patients with MJD from five unrelated families and 11 patients with sporadic or hereditary cerebellar ataxia other than MJD underwent a detailed neuro-otological and oculomotor(More)
Freezing of gait (FOG) is a common motor symptom of Parkinson’s disease (PD), which presents itself as an inability to initiate or continue gait. This paper presents a method to monitor FOG episodes based only on acceleration measurements obtained from a waist-worn device. Three approximations of this method are tested. Initially, FOG is directly detected(More)
There is only scant information on sleep characteristics and long-term follow-up in patients with Kleine-Levin syndrome (KLS). This study describes the clinical course, results of polysomnography and long-term follow-up in a relatively large group of patients with KLS. During the years 1982-97, we encountered 34 patients (26 males and eight females) with(More)
During the years 1982-1998, we encountered 7 adolescents and one young woman suffering from KLS. In 4 patients, hypersomnolence was accompanied by hyperphagia and hypersexuality, while in the remaining 4, recurrent hypersomnia was the only symptom. Mean age at onset of hypersomnolent attacks was 15.1+/-3.5 yrs. The mean duration of a hypersomnolent attack(More)

AIM To explore the epileptogenic potential of a newly introduced police car flash light device (930 Heliobe Lightbar). METHODS A 930 Heliobe Lightbar was installed in the EEG laboratory. Thirty patients with known epilepsy, 30 subjects with chronic headache who were otherwise healthy and 15 healthy volunteers were examined. RESULTS All the subjects(More)
A 68-year-old man presented with significant, asymptomatic, unilateral eyelash poliosis, not associated with any ophthalmic or systemic conditions. He reported that this started about 40 years ago with a few lashes in the central portion of his eyelid and that adjacent eyelashes subsequently became involved over the next 4 to 5 days. He had normal(More)
During July-August 1998, we encountered 4 patients who suffered from syringomyelia. The diagnosis in each case could not be reached on clinical grounds only, since the characteristic thermoanalgesia dissociation was absent in all patients. In each case the spinal MRI showed the typical intraspinal cystic lesion, which finally established the diagnosis and(More)
Among Parkinson's disease (PD) symptoms, freezing of gait (FoG) is one of the most debilitating. To assess FoG, current clinical practice mostly employs repeated evaluations over weeks and months based on questionnaires, which may not accurately map the severity of this symptom. The use of a non-invasive system to monitor the activities of daily living(More)
