Long-term memory is one of the fundamental cognitive abilities that plays a role in everyday life. As we age, long-term memory often declines and mild cognitive impairments and memory loss become a serious problem. Dr. Maureen Schmitter-Edgecombe researches the progression of mild cognitive impairment to more serious disorders, such as dementia and Alzheimers. In this interview she talks about the difficulties in diagnosing mild cognitive impairment and the differential diagnosis of dementias. In addition, she has investigated a number of approaches of how to best help individuals afflicted with dementia and how to best support the caregivers of individuals with memory impairments.
