Personalized brain imaging may improve outcomes for treatment-resistant depression
A new randomized clinical trial from investigators at Mass General Brigham's Neuroscience Institute and Department of Psychiatry suggests that using personalized brain imaging to guide transcranial magnetic stimulation (TMS) may improve outcomes for people with treatment-resistan
How zebrafish might be key to unlocking treatments for hereditary disease CADASIL
CADASIL, which stands for "cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy," is a hereditary disease that damages the brain's small blood vessels, causing recurrent strokes. Over time, CADASIL leads to a decline in cognitive function and

Geometric neural 'map' may help bilingual brains navigate between languages
Anyone who speaks more than one language knows the feeling of expressing the same thought through entirely different linguistic lenses. A new study by researchers at Rice University and Baylor College of Medicine reveals that the key to this translation ability is a shared geomet
Vulnerable ALS neurons reveal molecular warning signs before cell death begins
A new study from the Knight Initiative for Brain Resilience researchers may help explain an enduring mystery about amyotrophic lateral sclerosis (ALS): why the disease kills off some of the brain and spinal cord's movement-controlling neurons while others show greater resilience.
New mechanism found for neuronal death in Alzheimer's and frontotemporal dementia
New mechanism found for neuronal death in Alzheimer's and frontotemporal dementia
Markers of a new mechanism for cell death, called karyoptosis, have been found in the brains of patients with Alzheimer's disease and frontotemporal dementia (FTD).
Iron accumulation in the brain may contribute to neurodegeneration
Neurodegenerative diseases affect tens of millions of people worldwide. Among these, Alzheimer's and Parkinson's diseases are the most common; in the United States alone, the Alzheimer's Disease Association and Parkinson's Foundation report roughly 7 million people with Alzheimer
Special protein in the brain's cleansing system may contribute to loss of brain function i
Alzheimer's disease is a progressive and permanent loss of nerve cells in the brain. The breakdown causes memory loss, functional impairment and personality changes. In a new study published in Nature Aging, researchers found that the age-related reduction in a specific protein m
Identifying immune pathways driving aggressive brain cancers
A new study has uncovered a key mechanism that helps one of the deadliest brain cancers evade the immune system, according to the study published in The Journal of Clinical Investigation.
A healthy diet may still make a difference for people at higher risk of dementia
A healthy diet may still make a difference for people at higher risk of dementia
Brain changes that can eventually lead to dementia may begin many years before anyone notices symptoms such as memory problems, missed appointments or difficulty finding words.
How a brain messenger protein drives progression of Alzheimer's disease
Alzheimer's disease is driven by a buildup of a toxic protein called Tau that kills neurons. As toxic Tau spreads to new regions of the brain, symptoms worsen and ultimately become fatal.
Large MRI analysis uncovers brain-region thinning tied to depression
Major depressive disorder (MDD) is a psychiatric condition characterized by persistent feelings of sadness, a loss of interest in everyday activities, altered sleeping and/or eating patterns, low energy, and difficulty concentrating on tasks. While it is one of the most widesprea
Women with Parkinson's disease may show more Alzheimer's-related brain changes than men
Women with Parkinson's disease may be more vulnerable to Alzheimer's-related changes in the brain than men, according to new research presented at the European Academy of Neurology (EAN) Congress 2026. Parkinson's disease and Alzheimer's disease frequently co-occur in older adult
