A computational neuroimaging study has shed new light on the relationship between morphological changes in the brain in schizophrenia and the network architecture of the brain, providing evidence to support two network theories of the disorder.
Since its instigation in cancer research in the 1930s, the disease-staging concept has become a crucial tool in clinical research and medical practice. Two new papers have proposed biological staging and classification systems based on α-synuclein pathology for Parkinson disease and related conditions.
Success in a trial of low-intensity ultrasound combined with an amyloid-β antibody represents a major stride towards integrating pharmacological and nonpharmacological approaches to reduce the amyloid-β load in patients with mild Alzheimer disease. This trial also highlights the potential of therapeutic ultrasound modalities to combat neurodegenerative diseases.
A study now reveals that CSF, but not imaging, biomarkers for Alzheimer disease show weaker correlation to cognitive measures in Black people than in White people. The findings offer insights into Alzheimer disease biomarker utility across racially diverse groups.
