[Abstract]:BACKGROUND More and more research results at home and abroad show that amyotrophic lateral sclerosis (ALS) is a complex disease involving multiple systems as well as the motor system. About 10% of them are familial, and the rest are sporadic amyotrophic lateral sclerosis (fALS). About 50% of patients with sporadic ALS have cognitive and behavioral changes, and the clinical manifestations are similar to those of frontotemporal lobe degeneration. There is no specific treatment for this disease, and the clinical diagnosis is obviously lagging behind. To study the characteristics of brain structure and function in patients with sALS, and to study the pathogenesis of sALS by exploring the correlation with clinical indexes such as disease progression, severity and cognitive function score, and to search for potential imaging markers for early diagnosis of sALS. Objective To explore the characteristics of brain structure in patients with sporadic amyotrophic lateral sclerosis and to study the correlation between brain structure and clinical data in patients with sALS. Results (1) Cognitive assessment: MoCA score and language, abstract, delayed recall score, FAB score in sALS patients. The scores and Stroop task time were significantly lower than those in the control group. (2) Compared with the control group, sALS patients had significantly decreased gray matter density in areas including bilateral anterior central gyrus; (2) areas with significantly thinner cortex included: (left) superior temporal gyrus, anterior central gyrus, superior marginal gyrus; (right) superior frontal gyrus, insular lobe and anterior central gyrus; and (3) bilateral corpus callosum pressure. FA values in the posterior limbs of bilateral internal capsule, corticospinal cord, posterior/upper part of radiation corona, inferior longitudinal tract, lower frontal-occipital tract, superior longitudinal tract, genu/body/compression of corpus callosum, anterior thalamic radiation and posterior thalamic radiation increased significantly; (3) Correlation analysis 1) Patients with VBM:sALS The decrease of gray matter density in bilateral anterior central gyrus was not significantly correlated with clinical data; 2) SBM: the thickness of right anterior central gyrus was negatively correlated with UMN score (r = - 0.506, P = 0.023), and positively correlated with ALS FRS-R score (r = 0.534, P = 0.015); the thickness of left superior central gyrus was negatively correlated with time-consuming interference (C time-consuming-B) in SCWT test (r = - 0.538). DTI: Average FA of abnormal white matter fibers was positively correlated with MoCA visual spatial/executive function score (r = 0.662, P = 0.002). Average MD of abnormal white matter fibers was negatively correlated with disease progression rate (r = - 0.551.p = 0.01). Conclusion There were cognitive and behavioral impairments in patients with sALS, accompanied by extensive brain structural abnormalities. Cortical thickness of the lateral anterior central gyrus can be used as a potential indicator of disease severity, especially the extent of UMN involvement; thinning of the left superior marginal gyrus in patients with sALS can reflect impaired clinical executive function; and the average MD value of the whole brain white matter fibers has potential in predicting disease progression. Part II Sporadic amyotrophic lateral sclerosis Objective To explore the characteristics of brain function in patients with sporadic amyotrophic lateral sclerosis and to study the correlation between brain function and clinical data in patients with sALS. Results (1) Compared with the control group, the ALFF values of right parahippocampal gyrus, left infratemporal gyrus, left anterior cingulate gyrus, right superior frontal gyrus and left middle occipital gyrus in sALS group were significantly higher than those in the control group. (2) The ALFF values of right parahippocampal gyrus in sALS patients were positively correlated with the disease progression rate (r = 0.47). 3, P = 0.026; right parahippocampal gyrus (r = 0.514, P = 0.014), left infratemporal gyrus (r = 0.469, P = 0.028) and right superior frontal gyrus (r = 0.506, P = 0.016) were positively correlated with serum creatinine, respectively; left anterior cingulate gyrus ALFF was negatively correlated with MoCA visual space / executive function score (r = - 0.454, P = 0.04A). Conclusion The ALFF value of right parahippocampal gyrus in patients with sALS can be used as a potential predictor of disease progression rate; the ALFF value of left anterior cingulate gyrus can reflect executive function involvement; the higher serum creatinine level, the more compensatory brain function in patients with sALS.
