Parkinson’s disease (PD), a progressive neurodegenerative disorder impacting over 10 million people worldwide, is defined by the aggregation of misfolded α-synuclein (aSyn) in the substantia nigra pars compacta, leading to the hallmark motor symptoms of tremor, rigidity, and bradykinesia.

Persistent neuropsychiatric symptoms (NPS) in older adults could serve as early warning signs of underlying Alzheimer’s disease (AD) pathology, according to new research.

MRI continues to play a pivotal role in the early detection of Alzheimer’s disease, and new research suggests that using distance measures from MRI data may outperform traditional volumetric assessments in predicting cognitive decline.

Lewy body dementia (LBD), a complex neurodegenerative disorder, remains severely understudied in Latin America, according to a new scoping review analyzing the regional research landscape across major medical databases.

New research reveals that adults with rheumatoid arthritis (RA) are significantly more likely to develop sleep disorders, including insomnia, than those without the disease, a finding that raises important questions for rheumatologists and primary care providers.

In a comprehensive new study using National Health and Nutrition Examination Survey (NHANES) data from 1999 to 2020, researchers have identified strong links between specific lifestyle factors and the risk of stroke in U.S. adults.

In patients with branch atherosclerosis disease (BAD), early neurological deterioration (END) poses a significant threat to recovery, even in mild strokes.

At the American Academy of Neurology (AAN) Annual Meeting 2025, researchers presented new data from the long-term open-label extension of the Phase II VISIONARY-MS trial, reporting imaging and physiologic findings consistent with improved neuronal function and remyelination in patients with multiple sclerosis (MS).
