Other studies, however, reported persistent executive impairment in AUD patients after long-term periods of abstinence from months to years (Munro et al., 2000; Nowakowska-Domagala et al., 2017; Yohman et al., 1985).

However, it can occur earlier or later depending on the amount of alcohol a person consumes. Alcohol-related dementia can cause problems with memory, learning, judgment, and other cognitive skills.

  • Hippocampal CA1 pyramidal cells assist the hippocampus in communicating with other areas of the brain.
  • While forgetfulness and short-term memory might be the first signs, a person may go on to experience difficulties with executive functioning (like organizing and planning) and, in a later stage, problems with motor abilities.
