Sunil Pradhan (born 25 June 1957) is an Indian neurologist, medical researcher and writer, known for the invention of two electrophysiological techniques.
[1] Pradhan was born in the hill station of Najibabad, Bijnaur District, in the Indian state of Uttar Pradesh, on 25 June 1957.
[1][5] He did schooling at many local schools in Jhansi, Aligarh, Banda, Allahabad and Lucknow[1] and, choosing medical profession, he graduated in medicine, MB BS, from the King George's Medical University, Lucknow, in 1979 and did his post graduate studies in Internal Medicine (MD) there, which he completed in 1983.
[1] Pradhan started his career at Jaslok Hospital, Mumbai and later, shifted to the National Institute of Mental Health and Neurosciences (NIMHANS), Bangalore.
The next move was to the Institute of Human Behaviour and Allied Sciences (IHBAS) as the Head of the Department of Neurology and works there now as the Medical Superintendent since 2008.
[5] The legacy of Pradhan centres primarily around the five medical signs he has discovered, the two electrophysiological techniques he has invented and his research findings on the neuro diseases of Japanese Encephalitis, Hirayama type monomelic amyotrophy and epilepsy.
[6] He discovered that the DMD patients tend to suffer visible enlargement of the infraspinatus and deltoid muscles, which when contracted shows partial wastage.
[7] The sign was evident in patients with little calf muscle enlargement and visibly positive in DMD cases with 90% sensitivity.
[1] The second technique involves stimulating the intercostal nerves to study the somatosensory evoked potentials, for localizing the non compressive spinal cord lesions.
[1] He has also demonstrated standardized variables of contraction enhanced H‑reflex called R‑1 response and its utility in nerve root lesions where H-reflex is not electable.
[1] Pradhan found out that the Japanese‑B encephalitis (JE) sometimes produced selective lesions on the substrata nigra and this observation has assisted in eliciting a clue in explaining the early onset of Parkinson's disease.
[1] His findings led to a new clinical entity called Parainfectious conus myelitis, thus drawing an explanation for the unexplained urinary symptoms in young patients.
He is credited with the discovery of the role of immunoglobins in acute disseminated encephalomyelitis, a finding confirmed by many other researchers.
[16] His studies revealed that patients are likely to suffer from chronic epileptogenesis with poor seizure outcome if gliosis is present around their lesions.
[4] He has received many other awards such as: Pradhan has published several research papers in peer reviewed journals, both national and international in circulation.
[28] Nanojamians, a blog providing information on technological advancement in neuro sciences, has also listed many of his papers.
