Alcohol-related dementia is characterized by impaired executive functioning — planning, thinking, and judgment. Other features of alcohol-related dementia include:
Deficits with attention, concentration, and memory
Profound changes in personality
Reduced impulse control and emotional dysregulation — which can result in socially inappropriate behavior such as sexual disinhibition in public places
Onset may occur as young as 30 years old in some people, but it is more likely that alcohol-related dementia will present between the ages of 50 to 70, and its severity is directly proportional to how much the person has consumed in his or her lifetime.
