Vasomotor symptoms, including hot flashes in postmenopausal women, may contribute to memory performance problems. Neuroimaging reveals hot flashes caused alterations in brain function during memory encoding and retrieval tasks, specifically within the hippocampus and prefrontal cortex.
Researchers have identified the location of dysfunctional brain networks that lead to impaired sentence production and word-finding in primary progressive aphasia (PPA). PPA can occur in those with neurodegenerative diseases, such as frontotemporal dementia and Alzheimer's disease. Mapping the networks allows clinicians to apply non-invasive brain stimulation to potentially improve speech in those with PPA.
Machine learning can predict, with significant accuracy, whether a person is a musician or not, based on fMRI data collected while subjects listened to music.
Memory decline that starts during middle age may be the result of changes in what information the brain focuses on when forming and retrieving memories.
