It is often "accidentally" diagnosed via CT scan for other conditions involving the head/brain. The tell-tale Hemosiderin deposits are discovered either in the brain and/or the spinal column. Hemosiderin is an "iron salt", it is a residue, left behind during prior intracranial bleeding. While most people's bodies are able to "clean up" after a cranial or spinal bleed, those with SS are not. Nerve endings, synapses, etc, become coated with this Hemosiderin which interferes with proper nerve transmission and reception.
