Lack of physical activity is known to increase a person’s risk of Alzheimer’s disease. A new study in mice suggests that exercise may protect against Alzheimer’s by improving the regulation of iron metabolism in the brain. Regular exercise reduces circulating levels of a protein called interleukin-6 that promotes inflammation. The protein may also change the

Two new research studies have identified the neural signals underlying music imagery. These neural signals are related to melodic expectations and predictions. The researchers isolated, for the first time, the electrical neural signals of prediction by investigating moments of silence in music. They suggest a strong link between imagery, listening to music, and neural prediction

Brain images from people experiencing loneliness show distinct features within certain neural regions, suggesting that those who feel lonely may be able to fill their desire for human connection by imagining social contexts and interactions. Human connection is a key factor in people’s physical and mental health. However, the impacts of COVID-19 and the need

A review of research suggests that abnormalities in the front of the brain identified by electroencephalography (EEG) tests are common among patients who have neurological symptoms with COVID-19. Estimates vary, but approximately 15–25% of patients with severe COVID-19 may experience neurological symptoms, such as headaches, confusion, delirium, impaired consciousness, seizures, and strokes. Doctors may refer

Scientists recently found that the brains of young people exposed to air pollution display the markers of neurodegenerative diseases in their brain stems. A new study has shown that young adults and children exposed to air pollution have the markers of Alzheimer’s disease, Parkinson’s disease, and motor neuron disease in their brain stems. Alongside these

An updated report by a group of specialists lists 12 modifiable factors that, if a person acts on them, could reduce their dementia risk. Before this update, the report had listed nine modifiable factors. The 2020 report by the Lancet Commission on dementia prevention, intervention, and care appeared at the end of July in The
