Early life

Sachdev was born in Ludhiana, India and went to school in Solan, in the foothills of the Himalayas.[2] He received his MBBS from the All-India Institute of Medical Sciences (AIIMS) in 1978, his MD in psychiatry from AIIMS in 1981, and his PhD in psychiatry from UNSW in 1991.[1][3] He became a Fellow of the Royal Australian & New Zealand College of Psychiatrists (FRANZCP) in 1985.[3]

Clinical and research achievements

Sachdev is the Clinical Director of the NPI at the Prince of Wales Hospital.[1][2][4] He has played a leading role in the development of higher training in Neuropsychiatry through his leadership of the International Neuropsychiatric Association (INA), and the Neuropsychiatry Section of the RANZCP.[5] The major contribution of the NPI to psychiatric research has been in the field of Movement disorders, such as drug-induced Akathisia, tardive dystonia, Neuroleptic malignant syndrome, Tourette Syndrome, golfer's cramp and Psychomotor retardation in Melancholia.[6][7][8][9][10][11][12][13][14][15][16][17][18] In particular, akathisia and its subtypes were characterised, including the development of a rating scale and research diagnostic criteria.[19][20][21][22][23][24][25][26][27][28][29][30][31]

Other work has been in the areas of late-onset Schizophrenia[32] and secondary schizophrenia (including head injuries and schizophrenia-like psychosis).[33] Sachdev published the first negative study of Transcranial Magnetic Stimulation (TMS) for depression,[34] the first TMS treatment study of Obsessive Compulsive Disorder (OCD),[35] and the first study that examined the effect of different frequencies of TMS on an animal model of depression.[36]

Sachdev's early research was in the field of Transcultural psychiatry, including descriptions of Maori ethnopsychiatric constructs such as mana-tapu-noa and whakama.[37][38][39][40][41][42][43][44][45]

Since 1997, Sachdev's major area of research has been cognitive disorders.[46][47][48][49][50][51][52][53][54][55] He is currently directing a number of longitudinal, community-based studies of brain ageing, including the Sydney Memory and Ageing Study (MAS), the Older Australian Twins Study (OATS), the Sydney Centenarian Study (SCS), and the Sydney Stroke Study (SSS).[56][57][58][59][60][61] He is also a collaborator on one of the largest community-based studies of brain imaging: the Australian PATH Through Life Study [16]. Sachdev has contributed to the diagnosis of dementia as a member of the Neurocognitive Disorders Workgroup for the DSM-5.[62] He has also contributed to the field of epilepsy research as a member of the Task Force of the International League Against Epilepsy (ILAE) Neuropsychobiology Commission.[5]

Honours and awards

In 2011, Sachdev was made a Member of the Order of Australia (AM) for "services to medical research in the field of neuropsychiatry, as a clinician and academic, and to professional associations at a national and international level".[63][64] He has received numerous other awards, including the NSW Scientist of the Year in Biomedical Sciences (2010)[65] and the Organon Senior Research Award, Royal Australian & New Zealand College of Psychiatrists (RANZCP) for the best research by an Australian or New Zealand psychiatrist in the previous five years (1995).[2][5] He occupied the first chair of Neuropsychiatry in Australia.[5]

Sachdev is a Founding Executive committee member of the Tourette Syndrome Association of Australia.[2][63] He was elected President (2004–2006) of the International Neuropsychiatric Association.[2] Sachdev was international advisor to the Psychosurgery Review Committee of the American Neurosurgical Society and a member of the F1000 Reports advisory board. He has served on the editorial board of a number of international peer-reviewed journals, including the American Journal of Geriatric Psychiatry, Neuropsychiatric Disorders and Treatment, Acta Neuropsychiatrica and Current Opinion in Psychiatry.[2][66]
