Volume decreases in cortical areas, the amygdala, and basal forebrain in Parkinson's patients correlated with worsening symptoms of the disease.
A specific Parkinson's related gene could be a driver behind vocal production problems associated with the disease. The findings could lead to earlier diagnosis and treatment of Parkinson's disease.
People with Parkinson's disease have a clear genetic signature of the disease in their memory T-cells.
APOE proteins were enhanced in the brains of patients with dementia, even when they did not carry the Alzheimer's associated gene.
The COVID causing SARS-CoV-2 protein interacts with alpha-synuclein, speeding up the formation of amyloid plaques, a new study reports.
Microglia immune cells can join together to form networks when needed, a new study reports. However, certain mutations associated with Parkinson's disease can impair this process.
New findings reinforce the idea that dementia with Lewy bodies can be pathologically classified as two different and distinct disease types.
Chronic gut inflammation can trigger the clumping of alpha-synuclein in the walls of the colon, a new study reports. Researchers found chronic inflammation in the gut during early life can exacerbate the clumping of alpha-synuclein in the brains of older mice. The findings add to a growing body of evidence which links gut health to Parkinson's disease.
A new model of Parkinson's disease sheds light on the asymmetrical motor symptoms, and other disorders, associated with this disease.
Study sheds new light on the damage alpha-synuclein does to neurons in Parkison's disease patients.
Researchers have discovered a series of misfolded alpha-synuclein protein structures never previously observed. The alpha-synuclein fibers were larger than previously reported and adopted a striking variety of shapes. The work lays the foundation for a detailed analysis of misfolded alpha-synuclein structures and could provide a better understanding of the neurobiology of Parkinson's disease.
Researchers have identified two different shapes of alpha-synuclein associated with multiple systems atrophy (MSA) and Lewy body dementia. The structure of the protein is helical in MSA, causing the symptoms to occur more quickly and aggressively. In Lewy body dementia, the protein takes on a cylindrical form.
