A Cross-Sectional Study of Clinical Spectrum and Outcome of Pure Midbrain Strokes.

Background: Pure mesencephalic infarcts are uncommon, the main clinical manifestations being oculomotor signs and ataxia.

Objectives: Primary objective was to determine the incidence of pure midbrain strokes. We also evaluated the clinical spectrum, syndromes, arterial territories involved, risk factors, and outcome at 3 months.

Utility of IQCODE (Informant Questionnaire on Cognitive Decline in the Elderly) in Diagnosing Dementia in Malayalam Speaking Population.

Background: Among screening instruments used to diagnose dementia by interviewing the caregivers rather than the patients, Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) is widely used.

Objectives: To adapt and validate IQCODE in a Malayalam-speaking population and to study the utility of IQCODE in diagnosing dementia.

Materials And Methods: Cross-sectional study conducted as a two-phase survey on individuals aged ≥55 years availing dementia care services at three tertiary care hospitals and a dementia clinic in Kerala, India.

Alexia without Agraphia-report of Five Cases and Review of Literature.

Alexia without agraphia (also called pure alexia or word blindness) was the first of the disconnection syndromes to be described. It results from the loss of visual input to the language area without involvement of the language area. The most common cause is occlusion of the left posterior cerebral artery with involvement of left occipital cortex and the splenium of corpus callosum.

Neuropsychiatric Manifestations of Cognitively Advanced Idiopathic Normal Pressure Hydrocephalus.

Background: Neuropsychiatric manifestations of patients with idiopathic normal pressure hydrocephalus (iNPH) have not been studied in a systematic way.

Aim: To study the spectrum of neuropsychiatric abnormalities in patients with iNPH.

Patient Selection And Evaluation: Patients attending 3 different tertiary care centers during three consecutive time periods spanning from 2010 to 2015 were analyzed for neuropsychiatric manifestations.

Physical and biological response of the Arabian Sea to tropical cyclone Phyan and its implications.

The response to the tropical cyclone Phyan, which developed in the eastern Arabian Sea during 9-11 November 2009, was rapid cooling of sea surface temperature (SST), enhancement of chlorophyll a and two-fold increase in net primary productivity (NPP). Cooling of SST was immediate in response to the strong wind-mixing, and the subsequent upward Ekman pumping sustained the cooling even after the dissipation of Phyan. The biological response mediated by the upward Ekman pumping driven vertical transport of subsurface nutrient showed a time lag of 3-4 days.
