On the basis of a follow-up study of 146 schizophrenic patients preserving the development in the form of outlined attacks up to senility it was established that the recurrent development occurs only in 7.8% of the cases (more rarely than in the general population of schizophrenic patients). In some cases the transition from a recurrent development to an attack-like progressive form was observed. In most patients with recurrent schizophrenia in the late age the attacks cease. The analysis of the patients with attack-like progressive schizophrenia showed that the increase of defect occurred only in young and middle age and despite the repeated recurrence in involutional age and senility, the development of the disease on the whole remains non-progressive.
基于对146例精神分裂症患者的随访研究，这些患者病情以间歇性发作形式发展直至老年，结果发现病情反复发展的情况仅占7.8%（比精神分裂症患者总体人群中更为少见）。在某些病例中，观察到了从反复发展向发作样进行性形式的转变。在大多数老年反复型精神分裂症患者中，发作会停止。对发作样进行性精神分裂症患者的分析表明，缺陷增加仅发生在中青年时期，尽管在更年期和老年期病情反复出现，但总体疾病发展仍呈非进行性。
