There is a clear relationship between alcohol and neurodegeneration; for example, an alcohol use disorder correlates with a higher risk of Alzheimer’s disease. It is unclear, however, whether individual differences in brain structure and connectivity are risk factors for, or consequences of, alcohol use. New research exploring this relationship will be shared on Wednesday, 26 June 2024 at the 47th annual scientific meeting of the Research Society on Alcohol (RSA) in Minneapolis, Minnesota.

Altered Brain Connection Found in Kids with Chronic Nausea and Dizziness
Children with chronic nausea and a condition known as orthostatic intolerance (OI) (dizziness when standing up) exhibit brain connectivity changes in areas related to sensory external and internal awareness resulting in over self-monitoring, according to a study published in the journal Neurogastroenterology & Motility.
‘Brain Surfing’: Ultrasound waves focused on prefrontal cortex elevate mood and change brain connectivity in human volunteers
A team of researchers at the University of Arizona has found that low-intensity ultrasound waves directed at a particular region of the brain’s prefrontal cortex in healthy subjects can elevate mood, and decrease connectivity in a brain network that has been shown to be hyperactive in psychiatric disorders. The method uses transcranial focused ultrasound (‘tFUS’), a painless, non-invasive technique to modulate brain function comparable to transcranial magnetic stimulation (‘TMS’), and transcranial direct current stimulation (‘tDCS’). This study shows, for the first time, a correlation between tFUS-induced mood enhancement, and reorganization of brain circuits.
