Parenchymal hemorrhagic demyelination (PHD) is a mouth-ful of medical jargon that simply means “bleeding inside brain tissue that is also losing its insulating myelin...

Petechial Hemorrhagic Demyelination (PHD) is a pattern of injury inside the brain or spinal cord where the insulating myelin coat of nerve fibres breaks...

Your nerves are wrapped in a fatty, insulating coat called myelin. Think of myelin as the plastic around an electric wire: it lets impulses...

Remote Wallerian demyelination is a delayed form of nerve‐fiber breakdown that happens far away from the original injury site. After a nerve is damaged...

Parenchymal hematoma–associated demyelination (PHAD) is a form of white-matter injury that develops when bleeding inside the brain parenchyma (a parenchymal hematoma) damages the fatty...

Demyelinating disorders damage the fatty myelin sheath that insulates nerve fibers, slowing or blocking the electrical messages your brain and spinal cord send to...

Chronic Symptomatic Cerebral Syndrome is an umbrella description doctors use when the brain has been under long-term stress or injury and keeps showing clear,...
