Orthostatic Disorders of Blood Pressure Control: Clinical Features
Almost all the symptoms and signs attributable to the orthostatic disorders of blood pressure control appear to be the consequence of reduced cerebral blood flow. Blood flow to the brain is presumably reduced by the excessive orthostatic fall in blood pressure or diminution of cardiac output and the inadequacy of compensatory cerebral autoregulation. The chief symptoms reported by 159 patients are listed among the details of each subject in Appendix II. The frequency with which each of the main symptoms was elicited is shown in Table VII.
