A clinical rating scale which measured the severity of tremor in 20 patients (12 with essential tremor and 8 with "dystonic" tremor) was assessed at specific anatomical sites for both inter and intra-rater reliability using four raters. The scores obtained with the scale were compared with the results of upper limb accelerometry, an activity of daily living(More)
Epidemiological data on risk factors of Parkinson's disease (PD) are not available from India. In a case control study, we investigated environmental and genetic risk factors in the etiology of idiopathic Parkinson's disease. Three hundred seventy-seven patients of Parkinson disease (301 men, 76 women, mean+/-SD age 56.78+/-11.08 years) and equal number of(More)
OBJECTIVES To assess patterns, prevalence, and risk factors of motor fluctuations in an unselected population of Parkinson's disease patients attending Movement Disorders Clinic of a tertiary hospital. MATERIAL AND METHODS Eighty patients with Parkinson's disease were interviewed and data about their clinical characteristics, motor fluctuations, i.e.(More)
The present study attempts to find a correlation between low serum B-12 levels and dementias. A total of 178 patients of dementia were seen at the cognitive disorder clinic from 1996 to 1998. Serum B-12 levels were studied in 100 patients. 15 patients (39.5%) of Alzheimer's dementia had reduced B-12 levels, while only 5 patients (13.9%) with vascular(More)
BACKGROUND Given the constraints of resources, thrombolysis for acute ischemic stroke (AIS) is under evaluation in developing countries. Prothrombin time (PT), platelet count and activated partial thromboplastin time (aPTT) may not be feasible within the time window. AIM To evaluate the safety and efficacy of thrombolysis in selected patients without the(More)
Recent discovery of pathogenic mutations in the leucine-rich repeat kinase 2 (LRRK2) gene in Parkinson's disease (PD) patients in different ethnic groups have raised a hope of diagnostic screening and genetic counseling. We investigated the six most commonly reported mutations in LRRK2 gene among Indian PD patients, using PCR-RFLP method. Mutations G2019S,(More)
Ataxia telangiectasia is a genetically inherited multisystem disorder with predominant feature being telangiectasia and cerebellar ataxia. In this report, a family of three siblings suffering from ataxia telangiectasia is described. The proband presented with dystonia and dystonic myoclonus, both of which are rare presenting features of ataxia(More)
Single, small, enhancing lesions that often resolve spontaneously are frequent findings on CTs of Indian patients with seizures. Based on ELISA and biopsy data, the majority of these lesions are probably cysticercosis. To determine if these patients should be treated with albendazole, we performed a double-blind, randomized, placebo-controlled study(More)
Seizures and psychosis coexist in a large number of patients with epilepsy, and a significant amount of research on their relationship has been published. There are several reports and reviews on postictal and interictal psychosis in patients with epilepsy. We describe three patients with refractory temporal lobe epilepsy, each of whom presented with a(More)
