Early life and education Martin Johannes Lauritzen was born in the year 1952 in Copenhagen, Denmark. He earned his medical degree in 1978 and his Doctorate of Science (D.Med.Sci.) in 1988, both from University of Copenhagen, Denmark.database Kraks Blå Bog"CV" Martin J. Lauritzen, Rigshospitalet
Career From 1980-85, Lauritzen worked as a Research Associate at the Department of Neurology at Rigshospitalet, at the Department of General Physiology at University of Copenhagen and at the Department of Biophysics and Physiology at New York University. From 1985 to 1994, he got his clinical education at Copenhagen University Hospitals. In 1994, he started working as Senior Consultant and later Head of Department of Clinical Neurophysiology at Glostrup Hospital (later Rigshospitalet Glostrup) and became Clinical Professor of Clinical Neurophysiology at the University of Copenhagen in 1998. In 2004, Lauritzen was a visiting professor at the Department of Experimental Neurology at Klinikum Charité, Humboldt University. Since 2007, Lauritzen is also employed as Professor of Translational Neurobiology at the Department of Neuroscience, University of Copenhagen, Denmark.database Kraks Blå Bog"CV" Martin J. Lauritzen, Rigshospitalet Lauritzen has led a number of large research initiatives including a Strategic Brain Research Program at University of Copenhagen known as ‘Body & Mind’. In 2003, he was a founding member of the steering committee for COSBID, a large multi-center study of elucidating the mechanisms of acute brain disorders with focus on the impact of ‘brain tsunamis’, i.e. cortical spreading depolarization waves for the outcome of patients with brain trauma, hemorrhage and stroke.RIBBDD homepage In 2009, Lauritzen was one of the co-founders of the national Center for Healthy Aging (2009), and he has been a principal investigator of the mechanisms of cognitive decline in brain aging including both animal experimental and human research.Jessen SB, Brazhe A, Lind BL, Mathiesen C, Thomsen K, Jensen K, et al.

Work Lauritzen studies the mechanism of brain blood vessels, and the regulation of the cerebral circulation and the blood-brain barrier (BBB) in health and disease.Lauritzen M, Mathiesen C, Schaefer K, Thomsen KJ.

Spreading Depression, Spreading Depolarizations, and the Cerebral Vasculature. Physiol Rev. 2015;95(3):953-93. In his early career, he identified the cortical mechanism that underlie migraine in patients as a cortical spreading depolarization wave,Lauritzen M. Pathophysiology of the migraine aura. The spreading depression theory. Brain. 1994;117(Pt 1):199-210. and he showed that the same mechanism contribute importantly to brain pathology in acute brain injuries.Strong AJ, Fabricius M, Boutelle MG, Hibbins SJ, Hopwood SE, Jones R, et al.

Lauritzen has investigated the blood-brain barrier as diffusional barrier for macromolecules, that specific parts of small blood vessels control the trafficking of substances from blood and brain and that signalling molecules in the blood contribute to vascular barrier properties.Mathiesen Janiurek M, Soylu-Kucharz R, Christoffersen C, Kucharz K, Lauritzen M.

His studies unravel pathophysiological mechanisms in acute brain disorders, and communication pathways between nerve networks and blood vessels needed to control brain energy supply in health and disease.
