Alzheimer’s: A Study Identifies Four Brain Patterns Detectable Before Memory Loss

Each year, nearly 10 million new cases of dementia are diagnosed worldwide, according to the World Health Organization. In 60 to 70 percent of cases, it is Alzheimer’s disease. This rapid rise, which now affects millions globally, raises an unsettling question: why, and more importantly, how does Alzheimer’s develop? Until now, researchers have mostly focused on individual risk factors taken separately, such as depression, diabetes, stroke, or high blood pressure. But a recent study conducted by the University of California, Los Angeles, and published in the journal eBioMedicine takes a different approach. Instead of looking at isolated causes, it examines the disease’s progression and the way it unfolds over time.
