I went to Mayo Clinic in 2005 I was 36 with stroke like symptoms. After a MRI and cat scan that were negative my neurologist sent me for a spect scan a radioactive tracer was injected in my arm. The test showed hypo perfusion of blood to my brain. My disease is called s.r.e.a.t. syndrome which stands for steroid responsive encephalopathy with autoimmune thyroiditis. This is a mouthful HOPE TO FIND SOEONE WITH THIS. please write
