In some stroke survivors, pain refuses to honor the boundary of injury — it crosses the body's midline, appearing on both sides as if suffering itself seeks symmetry. Researchers at Kyoto University have now traced the molecular chain of events behind this rare bilateral phenomenon, mapping how a lipid called LPA ignites immune cells that carry inflammation across the brain's great bridge, the corpus callosum, to the uninjured hemisphere. Their findings, built on the ability to actually see these molecular patterns within living tissue, offer the first clear mechanistic portrait of mirror-imag

Scientists Uncover Molecular Pathway Behind Mirror-Image Pain After Stroke
Stroke patients experiencing bilateral mirror-image pain face compounded disability and reduced quality of life due to widespread pain affecting both body sides.
