Similar to Lewy bodies, Lewy neurites are proteinaceous formations found in neurones of the diseased brain, comprising abnormal α-synuclein filaments and granular material. They are a feature of α-synucleinopathies such as dementia with Lewy bodies, Parkinson's disease and multiple system atrophy (MSA), and are found in the CA2-3 region of the hippocampus in Alzheimer's disease.
