The Silent Two-Decade Build-Up of Alzheimer’s
Research indicates that changes in the brain associated with Alzheimer’s disease can begin long before symptoms appear. Despite this, most cognitive assessments occur only after memory loss or other concerns arise, providing a brief snapshot of a person’s mental health rather than a long-term view . Alzheimer’s, the most common form of dementia, has traditionally been associated with memory loss and cognitive decline in older adults. Studies have shown that the disease is linked to the accumulation of amyloid plaques and tau tangles in the brain. These changes may occur years before symptoms are noticeable. Dr. Lisa Barnes, a neurologist at the Rush Alzheimer’s Disease Center, notes that “by the time a patient shows clinical symptoms, significant brain changes have already taken place.” Current diagnostic approaches rely heavily on cognitive testing, which is generally administered after a person or their family notices changes. While these tests are useful for confirming a di...
