Ataxia-Telangiectasia (A-T) variant is a rare, inherited condition. It affects the brain (especially the cerebellum), the immune system, the lungs, and cancer defenses. “Variant”...

Arachnoiditis means the thin middle lining around your spinal cord—the arachnoid membrane—gets inflamed. This lining normally protects the nerves and lets spinal fluid flow...

Chronic arachnoiditis means long-lasting inflammation and scarring of the arachnoid, a thin covering around the spinal cord and nerve roots. Over time, the inflamed...

Adhesive arachnoiditis is a long-lasting inflammation and scarring problem of the arachnoid—the thin, spider-web-like layer that covers your spinal cord and the bundle of...

Arachnoiditis is long-lasting inflammation of the arachnoid membrane, which is one of the thin coverings that protect the spinal cord and spinal nerves. When...
