Research

Current projects

All our projects (present and past) have received ethical approval from various supervisory committees. Currently, our clinic is involved in the following projects:

Funded Projects

1. Development and validation of a comprehensive clinical and neuropsychological battery for use in the Indian context for patients with vascular cognitive impairment
Vascular cognitive impairment (VCI) occurs after a cerebrovascular accident (stroke, haemorrhage, etc) when patients face mild complaints with regard to memory, language, planning and organising skills. If unattended to at its earliest, there is possibility that VCI may progress to vascular dementia. The current project aims to create a neuropsychological battery to detect VCI at its earliest in the acute post-stroke period. Given the multilingual nature of the Indian population, the battery is currently being validated in multiple languages including Kannada, Telugu, Bengali, Hindi, Malayalam and English. This is a multi-centre project happening across 5 centres in India (Bangalore, Hyderabad, Kolkata, New Delhi, Trivandrum) and is funded by the Indian Council of Medical research (ICMR).

2. Multilingualism and Dementia: A hospital based study of language profiles
While language deficits can be noted in Alzheimer's disease, they may be more pronounced in certain neurodegenerative conditions like Primary Progressive Aphasia. Similarly, difficulty with speech and comprehension may also be seen after a stroke to certain parts of the brain. This project aims to understand the nature of decline in language skills in a multilingual Indian population with Alzheimer's disease, Primary Progressive Aphasias and post-stroke aphasia, if language decline (and in post-stroke aphasia, language recovery) is simultaneous or step-wise, and if different linguistic skills (grammar, syntax, semantics) are affected similarly in neurodegenerative conditions. This project is just underway and is funded under a Cognitive Science Research Initiative by the Department of Science and Technology (DST), India.

Non Funded Projects

1. Understanding acalculia using a stroke population
Difficulty with handling numbers and basic arithmetic operations is simply defined as acalculia. While certain parts of the brain have been found to be devoted to number and numerical processing, acalculia can result from damage to other parts of the brain that result in loss in memory and planning abilities, indirectly reflecting on performance on numerical tasks (secondary acalculia). We are currently investigating how strokes to different parts of the brain affect numerical abilities.
