Fourteen of 134 consecutively admitted manic patients exhibited emotional blunting in addition to the full manic syndrome. The authors compared these 14 blunted manic patients with the remaining 120 nonblunted manic patients and with 31 schizophrenic patients admitted during the same period. They found that the blunted manic patients more closely resembled schizophrenic than nonblunted manic patients on most of the demographic, clinical, and familial variables studied. Although mania with blunting may represent a variant of schizophrenia, the etiologic association between long-term neuroleptic administration and emotional blunting requires further study.
在134例连续收治的躁狂患者中，有14例除了具备完整的躁狂综合征外，还表现出情感迟钝。作者将这14例情感迟钝的躁狂患者与其余120例无情感迟钝的躁狂患者以及同期收治的31例精神分裂症患者进行了比较。他们发现，在大多数研究的人口统计学、临床和家族变量方面，情感迟钝的躁狂患者比无情感迟钝的躁狂患者更类似于精神分裂症患者。尽管伴有情感迟钝的躁狂可能代表精神分裂症的一种变体，但长期使用抗精神病药物与情感迟钝之间的病因学关联仍需进一步研究。
