Doctor Tsai has devoted his life to Parkinson’s disease, movement disorder, stroke care, and neurocritical disease. He is a member of the movement disorder group led by Professor Chon-Haw Tsai. He has joined the deep brain stimulation intra-operative multichannel microelectrode recording (MER) and has performed basic studies for Parkinson’s disease. He is also a stroke neurologist performing intra-arterial thrombectomy for hyperacute large artery occlusion patients. And in the intensive care unit, he takes care of patients with severe stroke, status epilepticus, or severe central nervous system infection. Doctor Tsai has won high reward in the improvement of patients, including the regaining consciousness. In the intensive care unit, he often says to patients, “Our goal is your being able to walk back home without others’ assistance.”
