Abstract
Despite growing interest the frequency and characteristics of frontal lobe functional and behavioral deficits in Chinese people with amyotrophic lateral sclerosis ALS as well as their impact on the survival of ALS patients remain unknown The Chinese version of the frontal assessment battery FAB and frontal behavioral inventory FBI were used to evaluate 126 sporadic ALS patients and 50 healthy controls The prevalence of frontal lobe dysfunction was 325 The most notable impairment domain of the FAB was lexical fluency 307 The binary logistic regression model revealed that an onset age older than 45 years OR 5976 P = 0002 and a lower educational level OR 0858 P = 0002 were potential determinants of an abnormal FAB Based on the FBI score 460 of patients showed varied degrees of frontal behavioral changes The most common impaired neurobehavioral domains were irritability 254 logopenia 206 and apathy 190 The binary logistic regression model revealed that the ALS Functional Rating ScaleRevised scale score OR 0127 P = 0001 was a potential determinant of an abnormal FBI Frontal functional impairment and the severity of frontal behavioral changes were not associated with the survival status or the progression of ALS by the cox proportional hazard model and multivariate regression analyses respectively Frontal lobe dysfunction and frontal behavioral changes are common in Chinese ALS patients Frontal lobe dysfunction may be related to the onset age and educational level The severity of frontal behavioral changes may be associated with the ALSFRSR However the frontal functional impairment and the frontal behavioral changes do not worsen the progression or survival of ALS
