10. Cognitive Changes, Memory Lapses, and Confusion
Perhaps the most alarming sign of advanced fatty liver disease involves noticeable changes in your mental clarity and cognitive function. A failing liver loses its ability to filter dangerous neurotoxins—particularly ammonia—out of your bloodstream. These unfiltered toxins freely travel to your brain, crossing the blood-brain barrier and disrupting normal neurological function. This condition, called hepatic encephalopathy, causes confusion, severe forgetfulness, drastically shortened attention spans, and personality changes. Tragically, in older adults, these critical warning signs frequently go misdiagnosed as the early onset of dementia or Alzheimer’s disease, significantly delaying life-saving liver treatments.
