目的： 分析脑白质稀疏症（ＬＡ）的智能评判结果．方法： ＣＴ 检查用Ｐｈｉｌｉｐｓ－Ｔｏｍ ｓｃａｎ ３５０型全身扫描机，按Ｍｉｒｓｅｎ 计分表示白质稀疏，即两侧均无病灶为０度，１～２个病灶为１度，３～５个病灶为２度，多于５个病灶为３度，融合病灶为４度． 智能检查采用长谷川量表与ＤＳＭ－４－Ｒ临床智能标准相结合， 临床表现由神经科医生询问病史及神经系检查做出．结果： １００例脑白质稀疏症中，智能无障碍２３例，轻度障碍２０例，中度障碍３４例，痴呆２３例． 智能障碍的发生率及程度与病程长短及ＬＡ的严重程度有关，ＬＡ并发多发脑梗塞中智能障碍发生率高达８３％ ． ＬＡ伴发智能障碍的临床特征主要有情感失控，尿便失禁，步态异常． 结论： ＬＡ的智能损害与ＬＡ的存在无关，而与ＬＡ的严重程度有关，ＬＡ 的存在提示随后卒中发生率增加，所以影像学上ＬＡ 的出现早于临床症状，可以了解患者的发展及预后．
Objective: To analyze the intelligent judgments of leukopenia (LA). Methods: The CT scan was performed on a Philips-Tom scan Model 350 Whole Body Scanner scored on a Mirsen basis to show white matter sparseness with no lesions on both sides of 0 degrees, 1 to 2 lesions on 1 degree, and 3 to 5 lesions on 2 degrees , More than 5 lesions 3 degrees, fusion lesions 4 degrees. The intelligent examination uses the Hasegawa Scale combined with the DSM-4-R clinical intelligence standard, and clinical manifestations are made by neurologists for medical histories and neurological examinations. Results: In 100 cases of white matter disease, there were 23 cases of mental disorder, 20 cases of mild disorder, 34 cases of moderate disorder and 23 cases of dementia. The incidence and extent of mental retardation and duration of disease and the severity of LA, LA complicated by multiple cerebral infarction in the incidence of mental retardation as high as 83%. LA associated with clinical manifestations of mental disorders are mainly emotional out of control, urinary incontinence, abnormal gait. CONCLUSIONS: The impairment of LA is not related to the presence of LA, but is related to the severity of LA. The presence of LA suggests an increased incidence of stroke. Therefore, the appearance of LA is earlier than clinical symptoms and can be used to understand the development and prognosis of patients.
