To investigate whether transcranial brain sonography (TCS) discriminates different courses of idiopathic Parkinson's disease (PD), 101 patients with clinically definite PD were studied. In four patients, TCS was not possible due to insufficient acoustic temporal bone windows. Substantia nigra (SN) hyperechogenicity was found in 96% of assessable patients.(More)
BACKGROUND In several pilot studies, transcranial brain sonography findings of substantia nigra and lenticular nucleus discriminated between idiopathic Parkinson disease (PD) and atypical parkinsonian disorders. OBJECTIVE To study the use of transcranial brain sonography in excluding the diagnosis of idiopathic PD in patients with sporadic parkinsonism.(More)
Nonconvulsive status epilepticus (NCSE) and epilepsia partialis continua (EPC) are common epileptic conditions for which straightforward recommendations based on controlled randomized trials for treatment in therapy refractory courses are lacking. In a large retrospective study on drug efficacy in status epilepticus (SE) we identified the patients treated(More)
BACKGROUND Cervical dystonia is managed mainly by repeated botulinum toxin injections. We aimed to establish whether pallidal neurostimulation could improve symptoms in patients not adequately responding to chemodenervation or oral drug treatment. METHODS In this randomised, sham-controlled trial, we recruited patients with cervical dystonia from centres(More)
OBJECTIVE To study the use of transcranial sonography (TCS) in discriminating between patients with dementia with Lewy bodies (DLB) and Parkinson's disease with dementia (PDD). METHODS Fourteen patients with DLB, 31 with PDD and 73 with PD without dementia (PDnD) were studied with TCS. RESULTS All assessable patients with DLB, 97% with PDD, and 94% with(More)
OBJECTIVES Deep brain stimulation of the internal pallidum (GPi-DBS) is an established therapeutic option in treatment-refractory dystonia, and the identification of factors predicting surgical outcome is needed to optimize patient selection. METHODS In this retrospective multicenter study, GPi-DBS outcome of 8 patients with DYT6, 9 with DYT1, and 38 with(More)
Therapy with intravenous immunoglobulins (IVIG) is thought to be a safe treatment for a number of immune-mediated neurological diseases. Published data about prevalence of adverse effects range from 11 to 81%. The purpose of our study was to present a representative view on adverse effects by analysis of a large cohort of patients treated by IVIG. In a(More)
BACKGROUND Gaucher disease (GD) is the most common lysosomal storage disorder (LSD). Based on a deficient β-glucocerebrosidase it leads to an accumulation of glucosylceramide. Standard diagnostic procedures include measurement of enzyme activity, genetic testing as well as analysis of chitotriosidase and CCL18/PARC as biomarkers. Even though chitotriosidase(More)
Deep brain stimulation (DBS) of the globus pallidus internus (GPi) is an effective treatment in primary dystonia. Its success depends on the implantation accuracy of the DBS electrode into the targeted GPi. Discrepancies of up to 4 mm between the initial target, selected on preoperative MRI, and the final DBS lead location are caused mainly by caudal brain(More)
BACKGROUND Fabry disease (FD) is an X-linked inherited disease based on the absence or reduction of lysosomal-galactosidase (Gla) activity. The enzymatic defect results in progressive impairment of cerebrovascular, renal and cardiac function. Normally, female heterozygote mutation carriers are less strongly affected than male hemizygotes aggravating disease(More)
