Foix-Alajouanine syndrome

Foix-Alajouanine syndrome is a rare condition that affects the spinal cord. Also called subacute ascending necrotising myelitis, it occurs when the veins on the surface of the spinal cord, including the extrinsic pial veins and the intrinsic subpial network, become chronically congested. This congestion can lead to a gradual worsening of spinal cord function over time. The condition is characterized by a progressive ascending deficit, meaning that weakness or loss of movement and sensation starts in one area and slowly moves upward over several months or even years. As a result, people with this condition may face a gradual decline in their ability to move and feel different parts of their body. The condition is complex and remains a subject of ongoing study, with researchers working to better understand its mechanisms and progression.

A key sign of Foix-Alajouanine syndrome is a progressive ascending deficit, where the loss of movement or sensation starts in one region and moves upward over time. Detailed information about additional symptoms is limited.

Foix-Alajouanine syndrome appears to result from chronic congestion of the spinal cord’s veins. Problems with the drainage of blood from the extrinsic pial veins and the intrinsic subpial network seem to play a major role in this condition. This build-up of blood over time may damage the spinal cord, although more detailed information on triggers or additional risk factors is not provided.
