HHV-6 encephalitis

HHV-6 encephalitis is a brain inflammation caused by an infection with the human herpesvirus 6. This condition can occur in people after an allogeneic hematopoietic cell transplantation, especially when using umbilical cord blood stem cells. It may also develop in people with immune system disorders. People with HHV-6 encephalitis often experience a range of symptoms and changes in brain function. The condition is recognized by symptoms such as confusion, difficulty in learning new information (anterograde amnesia), short-term memory loss, and seizures.

Common symptoms of HHV-6 encephalitis include confusion, problems with forming new memories (anterograde amnesia), short-term memory loss, and seizures. These symptoms reflect the inflammation occurring in the brain.

The cause of HHV-6 encephalitis is an infection with human herpesvirus 6. Increased risk is seen in people who have had an allogeneic hematopoietic cell transplantation, especially when umbilical cord blood stem cells are used. Individuals with immune system disorders may also be at higher risk.

Treatment for HHV-6 encephalitis involves using antiviral medications that target the HHV-6 virus. The approach helps to reduce the inflammation and manage symptoms, though details may vary based on individual factors.

The long-term outlook for HHV-6 encephalitis can vary widely depending on individual patient factors. Some people may recover fully, while others might experience lasting effects. Information about the long-term recovery process is specific to each case.

Information about current research and future directions is currently limited for this condition.
