Epilepsy drug-resistance may depend on the metabolism of antiepileptic drugs (AEDs), transport to the epileptic focus and/or target sensitivity. Furthermore, drug response depends on multiple characteristics of the patient, the epilepsy, and the antiepileptic drugs used. We have investigated the association between polymorphisms related to antiepileptic(More)
BACKGROUND AND PURPOSE The aim of this study was to determine the incidence, type, and prognosis of stroke in young adults in Cantabria, Spain. METHODS We investigated prospectively all patients aged 50 years or below who were admitted with the diagnosis of a stroke to the University Hospital "Marqués de Valdecilla" from April 1, 1986, to March 31, 1988.(More)
Mutations in the leucine-rich repat kinase 2 (LRRK2) gene have been shown to cause both autosomal dominant and sporadic Parkinson's disease (PD). The common G2019S mutation shows wide geographical distribution while R1441G has been only reported in Northern Spain. The overall frequency of these mutations remains to be established. To determine the(More)
We describe two patients with Friedreich's ataxia whose presenting symptomatology was for years progressive tabetic ataxia. Based upon the initial clinical, electrophysiological and nerve biopsy data, a diagnosis of idiopathic sensory neuropathy was established. Subsequent examination of the kin showed that three sisters of case 1 had Friedreich's ataxia.(More)
Sixty-four consecutive patients with clinically or laboratory-supported definite multiple sclerosis (MS) were evaluated prospectively for evidence of primary Sjögren's syndrome (SS). This diagnosis was established when a patient had objective keratoconjunctivitis sicca, xerostomia, or both together with positive labial salivary gland biopsy. We found 2(More)
Lamotrigine (LTG) is metabolized by UGT1A4 but UGT2B7 also contributes to its glucuronidation. The aim of this study was to determine whether UGT2B7_- 161C>T and UGT2B7_372A>G polymorphisms contribute to the intersubject variability in LTG concentration-to-dose ratio (LTG-CDR) in epileptic patients. Fifty-three white epileptic patients attending the(More)
Thirty-five CT scans were studied from patients with several forms of spinocerebellar degeneration. Atrophy was determined by objective measurements of the number and width of cerebellar sulci, transverse diameter and surface area of the fourth ventricle, brainstem ratio, cerebellopontine angle cistern, and Evans' index. Two-thirds of the patients with(More)
One hundred and thirty two individuals at risk for hereditary motor and sensory neuropathy (HMSN) type I from 11 unrelated families were evaluated by physical examination. Motor conduction velocity (MCV) studies of median and/or peroneal nerves were performed on 99 of them. Seventy-three subjects were found to be affected. In all age categories including(More)
Neoplasm is an uncommon cause of a parkinsonian syndrome. We report a woman with primary brain B-cell lymphoma presenting as Parkinson's disease. After 1 year of the illness, CT and MRI showed lesions without mass effect in the basal ganglia and corpus callosum. The patient did not respond to levodopa and right cerebellar and brain-stem signs appeared,(More)
