Zusammenfassung: | Background: Cognitive impairment secondary to frontal lobe atrophy exists in 40–60% of Amyotrophic Lateral Sclerosis (ALS) cases. We aimed to determine the prevalence of frontal‐lobe mediated behavioral impairment in (ALS) and to ascertain its relationship to cognitive impairment.
Methods: Two‐hundred and twenty five patients diagnosed with sporadic ALS were evaluated for behavioral dysfunction using the Frontal Systems Behavior Scale (FrSBe), a validated measure used to examine frontal‐lobe mediated behaviors, specifically apathy, executive dysfunction and disinhibition; a total behavior score is also provided. Additionally, a subset of patients also underwent a comprehensive neuropsychological evaluation.
Results: Changes in the total FrSBe scores were observed in 24.4% of the patients and 39.6% of the patients had impairment in at least one behavioral domain with symptoms of Apathy being the most common (31.1%). Cognitively impaired ALS patients had worse total (P = 0.05) and apathy scores (P |
