““Do not routinely give the diagnosis of Panic Disorder solely because patients complain of nervous, anxious, panicky, or fearful emotions—the criteria for Panic Disorder are mainly physical symptoms that are also associated with increased blood levels of adrenaline (epinephrine), lactic acid, and increased blood pH. Even the “psychological” symptoms of derealization, depersonalization, and fears of dying, losing control, and going crazy can be reproduced by artificially altering blood adrenaline levels and acid/base balance.””
