A short lived reduction in the brain's provide of blood or oxygen could lead to hypoxic-ischemic damage.

Two 1997 discoveries highlighted the importance of Lewy body inclusions in neurodegenerative processes: a mutation in the SNCA gene that encodes the alpha-synuclein protein was located in kindreds with Parkinson's disease, and Lewy bodies and neurites had been uncovered to become immunoreactive for alpha-synuclein.

It is especially helpful in the prognosis of inflammatory diseases of the central nervous method, Particularly infections, for instance meningitis. A lumbar puncture is also called a spinal tap.

During the early 1900s, though researching Parkinson's disease, the scientist navigate to this website Friederich H. Lewy discovered abnormal protein deposits that disrupt the brain's normal functioning.
