To specify forms of severity of mental disorders in neurocirculatory asthenia (NCA) for more precise differentiation between NCA as a nosological entity and syndrome.
The examination including specially-designed interview, ECG, echo-CG, orthostatic and hyperventilation tests, bicycle exercise, consultation of the psychiatrist, psychological tests covered 80 NCA patients (31 men, 49 women, mean age 29.2 +/- 9.08 years).
NCA is characterized by the absence of a clear link with psychoemotional stress, seasonal disease aggravations, weakness, dizziness, negative results of orthostatic and hyperventilation tests. Among NCA criteria, dominating are "additional signs". Patients with anxio-fobic, panic, anxio-depressive neurotic disorders are characterized by strong relations between manifestation, subsequent disease exacerbations with psychogenia; attack-like NCA manifestation, prevalence of "basic signs" among diagnostic criteria (cardialgia, pulse and blood pressure lability, nonspecific alterations of T wave, positive orthostatic and hyperventilation tests).
NCA presents at least with two variants. In the first variant NCA picture is characterized by hereditary or early acquired vegetative stigmation and secondary neurotic disorders; the second variant presents as a clinically formed illness in which NCA symptoms manifest as a syndrome which is a leading component of a mental disease.
明确神经循环性无力症（NCA）中精神障碍的严重程度形式，以便更精确地区分作为一种疾病实体的NCA和综合征。
检查包括专门设计的访谈、心电图、超声心动图、直立性和过度通气试验、自行车运动、精神科医生会诊、心理测试，涵盖80例NCA患者（31名男性，49名女性，平均年龄29.2±9.08岁）。
NCA的特点是与心理情绪应激、季节性病情加重、虚弱、头晕、直立性和过度通气试验阴性结果无明确关联。在NCA标准中，“附加体征”占主导。患有焦虑恐惧、惊恐、焦虑抑郁神经症的患者，其症状表现、随后病情加重与精神因素之间存在密切关系；发作样NCA表现，诊断标准中“基本体征”（心前区疼痛、脉搏和血压不稳定、T波非特异性改变、直立性和过度通气试验阳性）占优势。
NCA至少有两种变体。在第一种变体中，NCA表现的特点是遗传性或早期获得性植物神经标记和继发性神经症；第二种变体表现为一种临床形成的疾病，其中NCA症状表现为一种综合征，是精神疾病的主要组成部分。
