Mast cell activation disorders can cause mast cells to release mediators almost anywhere in the body, including the brain, according to Mastocytosis Society Canada. Patients with mast cell disorders may have a variety of symptoms, each with one or more triggers, and should keep a log of possible triggers and symptoms. There are over 58 possible symptoms, such as vertigo, skin lesions, fatigue, sudden drops in blood pressure, vomiting, cognitive impairment, headaches, joint pain, hair loss, sensitivity to sunlight, eye pain, vision problems and shortness of breath.
