ABSTRACT
【Objective】 The involvement of upper motor neuron (UMN) degeneration is crucial to the diagnosis of amyotrophic lateral sclerosis (ALS). This study aimed to determine objective and sensitive UMN degeneration markers for an accurate and early diagnosis. 【Methods】 A total of 108 ALS patients and 90 age- and gender-matched control subjects were recruited from ALS Clinic of The First Affiliated Hospital of Xi’an Jiaotong University. The motor homunculus cortex thickness data in MRI were collected from all the participants. The clinical characteristics and UMN clinical examination of bulbar, cervical, thoracic and lumbosacral regions were collected from the ALS patients. 【Results】 Cortical thickness was significantly thinner in the ALS group than in the control group in bilateral head-face-bulbar and upper-limb areas (P<0.05). The cortical thickness of the global UMN positive group was significantly thinner than that of control groups in bilateral head-face-bulbar and upper-limb areas (P<0.05). The cortical thickness of the UMN positive group in the corresponding region was significantly thinner than that of control groups in bilateral head-face-bulbar and upper-limb areas (P<0.05). 【Conclusion】 The thinning of the motor homunculus cortex can be used as an objective marker of UMN involvement in ALS patients in clinical practice.
