Cognitive assessment of a sample of Egyptian patients with amyotrophic lateral sclerosis

Abstract Background Cognitive and behavioral changes in ALS are featured as an integral part of the disease. A noticeable proportion of ALS patients present with a full-blown picture of frontotemporal dementia, which is considered the most common form of cognitive impairment in ALS. Results A total of 30 ALS cases and 30 sex, age and education matched healthy controls were enrolled; their sociodemographic data were statistically insignificant as regards (age, sex, education). Regarding cognitive and behavioral assessment using the ECAS-EG, both ECAS mean total score and subdomains mean scores were significantly lower in ALS patients compared to controls ( p -value < 0.001), with statistically significant relation between ALS clinical staging and ECAS total scores ( p -value < 0.001). Furthermore, it was found that mean scores of nearly all ECAS domains are lower in early-onset group with longer duration of illness than late onset with short duration of illness but with a non-statistically significant difference. Conclusion ALS causes significant cognitive impairment, with relation between functional status and clinical staging of the disease with the severity of cognitive and behavioral dysfunctions and although early-onset cases had lower score on ECAS compared to those with late onset, but it was non-significant.
