What are the symptoms of low cerebral (brain) blood pressure?

Low brain blood pressure leads to suboptimal delivery of oxygen to the brain. This triggers a compensatory response by the brain to boost pressure and oxygen delivery. Symptoms such as a craving for salt and sugar, increased hyperactivity, toe-walking, laying flat on the sofa frequently all increase blood flow to the brain. Low pressure can cause anxiety, aggression, poor focus (ADD/ADHD), and headaches. The low pressure will slowly improve as the brain begins to repair the underlying autonomic nervous system injuries that lead to low blood pressure.
