Spatial neglect as a multifaceted syndrome may consist of perceptual/attentional as well as motor/intentional components. The present study investigated the lesion anatomy underlying perceptual and response bias using a manual response Landmark task (Bisiach, Ricci, Lualdi, & Colombo, 1998) in 68 patients with right-hemispheric stroke. The two differential aspects of the neglect syndrome were assessed by measuring response tendencies resulting from underestimations of the length of left line segments and from hypometric movement execution towards contralesional space, respectively. Perceptual and response bias were orthogonal components of task performance in the Landmark task. Perceptual as well as response bias both explained variance in the performance of standard paper-and-pencil neglect tests. While lesions within middle frontal, inferior parietal and parieto-occipital brain regions were related to perceptual bias, subcortical lesions within the caudate were related to response bias in the Landmark task. Our data suggest that perceptual/attentional and motor/intentional aspects of neglect are independent components of the syndrome with differential neural underpinnings in fronto-parietal and subcortical brain regions.

Sri Lanka has an ageing population with an impending epidemic of stroke at hand. Stroke is the leading cause of adult disability in Sri Lanka. Sri Lanka has seen many recent advances in stroke services in the recent past providing a benchmark example for the countries in the Asia Pacific region, modeling the best care for stroke patients across the region with limited facilities they have. Three postgraduate trainees in neurology and medicine from Sri Lanka will spend a year at Western Health/ University of Melbourne, Melbourne, Australia for a period of 12 months for training in neurorehabilitation for stroke. It is timely for neurology trainees and trainees in internal medicine in Sri Lanka to be interested in neurorehabilitation. We sincerely hope the Board of study of Neurology, Post Graduate Institute of Medicine, Colombo, Sri Lanka will take the necessary steps to establish neurorehabilitation as an emerging sub-specialty for neurology trainees in Sri Lanka now.

This study compares demography, risk factors and outcome of lacunar (LAC) and non-lacunar (non-LAC) strokes from the prospective hospital based stroke registry at Colombo South Teaching Hospital from 1st March 2012 to 30th June 2013. Data on admission, discharge and at 28 days after discharge were analysed. There were 229 ischaemic stroke (IS) patients. Average age was 65.7 years (SD 12.2, range 34-94) and 116 (50.7%) were males. LAC (n=130, 56.8%) were common than non-LAC (n=99, 43.2%). There were 75 (64.7%) males and 55 (48.7%) females in the LAC group (adjusted OR 2.1, 95% CI 1.08-4.29). Atrial fibrillation was less frequent among LAC stroke (OR 0.3, 95% CI 0.09-0.99). Hypertension, diabetes, smoking, dyslipidaemia did not differ in the two groups. Lower NIHSS (5.34 Vs 6.6, p= 0.053), higher GCS (14.7 Vs 13.3, p=0.001) were seen in LAC. Disability (MRS, Barthel index) on discharge, at 28 days and mortality during hospital stay and within 28 days was lower in the LAC group (p <0.001).
