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. These Lewy body proteins are found in an area of investigate this site your brain stem where by they deplete the neurotransmitter dopamine, causing Parkinsonian symptoms.
