Researchers of Rush University Medical Center in Chicago have uncovered that individuals with dementia are unaware that their memory is fading. Additionally, this lack of awareness can begin to occur up to three-years prior to diagnosis.
Dementia is a condition which impairs a person’s ability to think and speak and leads to memory loss. There are many different types of dementia, the most common being Alzheimer’s disease. Alzheimer’s disease is the sixth leading cause of death in America, according to the Alzheimer’s Association. It is estimated that 5.3 million Americans currently have Alzheimer’s disease.
Lack of awareness regarding memory loss is common in those with dementia, but until now researchers were unsure of how prevalent it was, when it develops or why some people are more affected by it than others.
For the latest research 2,092 participants from three longitudinal studies – who reported no memory loss or cognitive impairment prior to the study – were analyzed. For 10 years participant were tested annually to evaluate cognitive abilities. The average age of participants was 75.
