Memories of traumatic experiences can lead to mental health issues such as post-traumatic stress disorder (PTSD), which can destroy a person’s life. It is currently estimated that almost a third of all people will suffer from fear- or stress-related disorders... Continue Reading →

Research links Tau aggregates, cell death in Alzheimer’s

New evidence suggests a mechanism by which progressive accumulation of Tau protein in brain cells may lead to Alzheimer’s disease. Scientists studied more than 600 human brains and fruit fly models of Alzheimer’s disease and found the first evidence of... Continue Reading →

Scientists show how brain circuit generates anxiety

Neuroscientists at Cold Spring Harbor Laboratory (CSHL) have identified a neural circuit in the amygdala, the brain’s seat of emotion processing, that gives rise to anxiety. Their insight has revealed the critical role of a molecule called dynorphin, which could serve as... Continue Reading →

Complete remission of brain metastasis of difficult-to-treat tumor

In a letter to the New England Journal of Medicine, a Massachusetts General Hospital (MGH) research team reports a remarkable treatment response in a patient participating in a clinical trial of a novel immune-system-based cancer therapy. Treatment with an investigational... Continue Reading →

Making brain implants smaller could prolong their lifespan

Many diseases, including Parkinson’s disease, can be treated with electrical stimulation from an electrode implanted in the brain. However, the electrodes can produce scarring, which diminishes their effectiveness and can necessitate additional surgeries to replace them. MIT researchers have now... Continue Reading →
