We retrospectively investigated medical records of 196 patients suspected of having mental retardation at their initial visits. The objective of the study was to clarify the current choice of medical examinations and to assess their usefulness. Frequently selected examinations included 1. neuroimaging, neurophysiology and other central nervous system examinations, 2. psychological examinations and 3. blood tests. The former two demonstrated abnormal results very frequently. Genetic examinations rarely showed abnormal results. On the contrary, chromosomal analysis was often useful for diagnosing diseases that are difficult to be made only by clinical symptoms. Physicians should provide patients and their families with information about medical examinations currently available and useful.
我们回顾性研究了196例初诊时疑似智力发育迟缓患者的病历。本研究的目的是明确当前医学检查的选择并评估其效用。经常选择的检查包括：1. 神经影像学、神经生理学及其他中枢神经系统检查；2. 心理检查；3. 血液检查。前两项检查经常显示异常结果。基因检查很少显示异常结果。相反，染色体分析对于诊断仅靠临床症状难以确诊的疾病常常很有用。医生应向患者及其家属提供有关当前可用且有用的医学检查的信息。
