Brain injury-induced neurological deficits typically develop on the contralateral side of the body and include abnormal posture, motor weakness, and spasticity. It is believed that the interruption of descending neural pathways that convey supraspinal commands to the motoneurons in the spinal cord is the main cause of these deficits. This long-standing paradigm was challenged by our recent findings: a unilateral injury of the hindlimb sensorimotor cortex of rats with prior complete transection of the spinal cord produced hindlimb postural asymmetry (HL-PA), asymmetric hindlimb withdrawal reflexes, and asymmetry in gene expression patterns in the lumbar spinal cord (Figure 1; Lukoyanov et al., 2021). Strikingly, the contralateral hindlimb was flexed as usually seen in rats with intact spinal cord after brain injury.

1病例报告 患者女,65岁.“意识障碍、发热1 d余”于2019-9-4入院.患者9月3日出现口吐白沫,意识模糊,但呼之可应,有小便失禁,无肢体抽搐,遂送至当地医院就诊,行头部CT检查未见脑出血,最高体温达39.5℃.考虑“脑血管意外”,给予营养神经、护胃、补液、降温等处理后症状未见缓解,当天20点左右患者意识障碍加重,呼之不应,遂转至作者医院就诊.
