A groundbreaking study has revealed a symptom of Alzheimer’s disease that may appear up to 25 years before the onset of memory loss, challenging the common perception that memory problems are the first indicator. Researchers have found that subtle changes unrelated to memory, such as alterations in sensory processing or behavior, could serve as early warning signs of the disease. This discovery opens new avenues for early diagnosis and intervention, potentially improving patient outcomes by addressing the condition long before it progresses to noticeable cognitive decline. By focusing on these early indicators, healthcare professionals may be able to implement preventative measures that delay or reduce the severity of Alzheimer’s disease.
