@speechless623 - Here is some information on how stiff person syndrome is diagnosed.
Excerpt from linked page... "A definitive diagnosis can be made with a blood test that measures the level of glutamic acid decarboxylase (GAD) antibodies in the blood. People with SPS have elevated levels of GAD, an antibody that works against an enzyme involved in the synthesis of an important neurotransmitter in the brain." - Stiff-Person Syndrome Information Page | NIH: https://www.ninds.nih.gov/Disorders/All-Disorders/Stiff-Person-Syndrome-Information-Page
