Dementia is characterized by an irreversible, progressive, neuropsychiatric condition that affects the individual’s cognition and function and can result in costly long-term care. Alzheimer’s disease is the most common cause of dementia and an estimated 6.5 million older Americans are living with this incurable brain disorder that causes dementia and ultimately robs people of their ability to carry out everyday tasks. When the disease is diagnosed early, medications and cognitive therapies can be used to delay its progression and provide better quality of life to these individuals and their families. However, diagnosing Alzheimer’s and other dementias in its early stages is challenging as reliable biomarkers are not yet widely available.
