In chronic schizophrenic patients, mental functions with aging were examined in three studies. In study 1, memory functions on middle age groups and old age groups in schizophrenic and normal subjects were investigated via the Yokota Memory Test. Schizophrenic patients performed significantly worse than normal subjects did and memory functions in schizophrenic patients declined as same as normal subjects with aging. This result suggested that schizophrenic patients not only had a disorder of memory functions but also deteriorated memory functions with aging. In study 2, the Tree Test (Der Baumtest) and the General Health Questionnaire (GHQ) were administered to middle age and old age schizophrenic patients. In the Tree Test old age subjects drew a tree significantly more realistic, more proportional, and less dynamic than middle age subjects did. Schizophrenic patients ameliorated drawing of the tree with aging. Scores of GHQ in old age schizophrenic patients were not significantly different from scores of middle age one. This result suggested that both of middle and old age groups complained their physical and mental condition in a same manner. In study 3, in old schizophrenic patients the Tree Test was examined twice at intervals of 14-18 months. The second drawing of the tree became signaificantly more realistic, more proportional, and less dynamic than the first one. This suggested that drawing of the tree ameliorated within several months in old schizophrenia. In conclusion, memory functions declined but drawing of the tree improved with aging in schizophrenic patients.

三项研究对慢性精神分裂症患者的心理功能随年龄增长的情况进行了检查。在研究1中，通过横田记忆测试对精神分裂症患者和正常受试者的中年组和老年组的记忆功能进行了调查。精神分裂症患者的表现明显比正常人差，随着年龄的增长，精神分裂症患者的记忆功能与正常人一样下降。这一结果表明，精神分裂症患者不仅存在记忆功能障碍，而且随着年龄的增长，记忆功能也逐渐恶化。在研究2中，对中老年精神分裂症患者进行了树测试（Der Baumtest）和一般健康问卷（GHQ）。在树测试中，老年受试者画的树明显比中年受试者画得更真实、比例更匀称、动态也更小。精神分裂症患者随着年龄的增长，对树的描绘会有所改善。老年精神分裂症患者的GHQ评分与中年患者的GHQ评分没有显着差异。这一结果表明，中老年群体对自己的身体和精神状况的抱怨方式相同。在研究 3 中，对老年精神分裂症患者进行了两次树测试，间隔时间为 14-18 个月。与第一幅相比，第二幅树的画法明显更加真实、比例更大、动态性也更弱。这表明，老精神分裂症患者画树的情况在几个月内得到了改善。总之，随着年龄的增长，精神分裂症患者的记忆功能会下降，但画树的能力会有所改善。
