Parkinson’s Disease Is Not One, but Two Diseases

Parkinson's disease can be divided into two variants that start in different places in the body. For some, the neurodegenerative disease starts in the intestines and spreads to the brain. In others, the disease begins in the brain and spreads to the intestines and other organs. Read More

Alzheimer’s Protein in Blood Indicates Early Brain Changes

Blood samples taken from people enrolled in an Alzheimer's research study revealed higher levels of phosphorylated tau 217 that correlated with the presence of amyloid plaques. People with amyloid in their brains had up to three times more of the tau protein in their blood than those who had no evidence of amyloid accumulation. The higher levels of the protein were evident even in people with no signs of cognitive decline. Read More

New gene may drive earliest brain changes in Alzheimer’s

Genetic analysis of almost 4,300 samples reveals a link between the appearance of amyloid deposits, APOE, and a novel gene called RBFOX1. Lower levels of RBFOX1 in the brain appear to be associated with increased amyloid and global cognitive decline over a person's lifetime. Read More

Study finds evidence for reduced brain connections in schizophrenia

Neuroimaging study reveals decreased levels of the SV2A protein in synapses in patients with schizophrenia. The decrease in the protein could underlie the cognitive difficulties experienced by those with schizophrenia and provide new targets for treatment. Read More
