Neurangiosis is used to designate inherently functional but different in origin and symptoms vegetative disturbances caused by the impaired neurohumoral regulation of the vegetative function.
This kind of disturbances usually occurs during neuroses, hypodynamia, endocrine disharmonies during pubertal and climacteric periods, as well as neurosis-like states caused by neuropsychic or physical overwork, infections, intoxications, abstinence (in case of toxicomania
The neurangiosis pathogenesis usually deals with impaired regulation of the vegetative activity at all levels - from the brain cortex to the peripheral segments of the vegetative nervous system (including adreno- and cholino- receptors of the executive organs), as well as endocrine regulation segments. However, depending on the neurangiosis form and aetiology, the principal pathogenetic value for any level - cortical, subthalamic, etc. - can be specified, with the prevailing activity of either the parasympathetic or sympathetic vegetative nervous system segment.
The majority of patients have some form of asthenia or other - fatigue, irritability, a sleep disturbance, a low pain sensitivity threshold with different by senesthopathias (a sensation of insufficient breathing, cardialgia, a burning sensation in different parts of the body, etc.).
Among other vegetative dysfunction symptoms are a sensation of palpitation (in case of a predilection for sinus bradycardia or tachycardia), supraventricular (sometimes ventricular) extrasystolia, Bouveret's disease, pathological vasomotorr reactions - a sensation of fever and cold, a rise or fall in arterial pressure, skin pallor or hyperemia, hand and foot chilliness, overall or mainly local (axillary, palmar) sweating, secretory and motor gastrointestinal tract
dysfunction, sexual function disturbances, etc.
