Data are presented on the state of cerebral haemodynamics in patients with neuro-circulatory hypotension that was studied by measuring the arterial pressure in various zones of blood supply (the central retinal artery, superficial temporal artery and the brachial artery), by studying the ocular fundus and by rheoencephalography. The cerebral haemodynamic disorders were revealed in the form of regional cerebral hypertension in 13.4% and regional cerebral hypotension in 29.4%, against the background of a general fall of the arterial pressure. In regional cerebral hypertension the vessels of the ocular fundus were narrowed, in regional cerebral hypotension--vice versa. The reduction of the pulse pressure during neuro-circulatory hypotension also attracts attention, and it can be considered a sign of impaired blood supply to the brain.
