This document discusses alcohol-related brain injury (ARBI), its effects on individuals, families, and society. ARBI is caused by excessive alcohol intake and nutritional deficiencies, leading to structural and functional changes in the brain affecting memory, executive functions, and balance/coordination. It can affect 0.4-2.8% of the general population and is prevalent in acute hospital patients, homeless populations, prisons, and those with dementia. Caring for someone with ARBI can be challenging for families who experience ambiguous loss and difficulties accessing services. With proper support, individuals with ARBI and their families can learn to manage symptoms and live successfully in the community.
