Lab name: Prevention and treatment of Alzheimer’s diseaseTheme-Based Group: Aging, Cognition, and Alzheimer’s Disease
Division: Clinical Research
The focus of my research is on the prevention and treatment of Alzheimer’s disease in the preclinical, prodromal and early clinical stages, using new pharmacological (drug trials), and non-pharmacological (yoga and meditation) tools.
The research plan for the memory clinic envisaged the establishment of a cohort of well investigated subjects in different stages of evolution of Alzheimer’s disease. i.e. (i) Normal aging, (ii) preclinical, prodromal and early clinical stages of Alzheimer’s disease and (iii) moderate-severe stages of Alzheimer’s disease.
In this context we have currently the following projects:
(1) Canadian consortium for neurodegeneration in aging (CCNA) – A longitudinal study. We are recruiting healthy elderly and patients in the prodromal, preclinical and early Alzheimer’s stages. Periodic measures would include physical, psychiatric and cognitive evaluations. In addition, imaging and neurocognitive measures would be included in the periodic evaluation. The purpose is to gather data during the longitudinal course of the illness.
(2) Clinical trial of disease modifying agents in prodromal and early Alzheimer’s disease.
i. Beta-secretate inhibitor (Merck) in prodromal and early AD.
ii. Gantenerumab (Roche) in early AD
iii. Aducanumab (Biogen) in amnesic MCI
(3) Effect of yoga and meditation in healthy control subjects and in subjects with amnesic MCI. An FMRI study- Graduate student project (Ishan Walpola- Master’s Student)- Co-supervised by Dr. Pedro Rosa-Neto.
• Undergraduate medical training at the Government Medical College, Trivandrum, India. 1953-1958
• First psychiatric training at the National Institute of mental health and neuroscience, Bangalore, India- Leading to D.P.M. (Diploma in psychological medicine)
• Further in graduate studies in internal medicine and psychiatry 1965-1968- at Guy’s Hospital Medical School, London, England. Leading to M.R.C.P. from the royal college of Physicians and Surgeons of Glasgow in 1965 and fellowship in 1971. Membership at the royal college of Psychiatrists in 1971 (MRCPsych) and fellowship in 1981 (FRCPsych)
• Fellowship of the royal college of physicians and surgeons of Canada in 1972.
• Joined Douglas in 1972 as co-ordinator of research services under Dr. Heinz Lehmann. Upon Dr. Lehmanns’ retirement in 1976, re-organised the research department into the Douglas hospital Research center in 1979- was its scientific director until 1995. Then appointed as the first ‘psychiatrist in chief’ of the Douglas. Took over as the medical director of the dementia program in 2000.
• Honors: 1- CCNP medical honor in 1991
2- Exemplary psychiatrists award from the national association for the mentally ill (NAMI) –U.S.A 1993
3- Heinz Lehmann award for excellence in psychiatry from AMPQ (Association des medecins psychiatric du Quebec) -2010
4- Life time achievement award from the Canadian Academy of geriatric psychiatry – 2011
5- Canadian psychiatry association- John Cleghorn award for excellence in clinical psychiatric research – 2014
• Research: (1) Initial work in study of circadian rhythms of melatonin and cortisol- in aging and the Douglas longitudinal study of brain aging in collaboration with Sonia Lupien and Michael Meaney.
(2) Neuro endocrine studies- in schizophrenia, depression and aging – in collaboration with Dr. S. Lal and Dr. R. Quirion.
(3) Clinical trials in schizophrenia, depression and currently in Alzheimer’s disease. In Alzheimer’s disease, current projects related to disease modifying treatments based on the amyloid hypothesis and the potential of yoga and meditation to prevent age related neurodegeneration.
