Blood Test May Identify Alzheimer's Risk

A new study indicates that Alzheimer's disease can cause the brain's immune cells to mistakenly target healthy nerve cells. This loss of smell may serve as an early indicator of the disease. The research findings suggest a link between olfactory changes and neurological degradation. No specific institution or lead researcher was named in the report. Scientists are investigating how this immune response contributes to brain damage. This mechanism involves the immune system attacking the brain's own neural structures. This diagnostic method utilizes brain scanning technology to monitor these cellular actions. The test provides a way to detect the progression of the disease through blood analysis. Researchers are focusing on how these immune responses lead to nerve damage.
