Dementia is an umbrella term for various neurological conditions that lead to impaired cognitive abilities. If someone has a form of dementia, they may experience a gradual decline in memory, problem-solving skills, and judgment. Dementia
can interfere with day-to-day functioning, causing confusion, irritability, problems recalling names and dates, and the frequent loss of important items. This can have a negative effect on the person’s sense of independence and their social and emotional well-being. While as many as half of those aged over 85 may experience some form of dementia, it is not an inevitable part of aging.
