Multicenter Study
Cortical atrophy in ALS is critically associated with neuropsychiatric and cognitive changes.
To characterize the patterns of brain atrophy in patients with amyotrophic lateral sclerosis (ALS) with and without cognitive and neuropsychiatric symptoms, in comparison to controls and patients with ALS-frontotemporal dementia (FTD). ⋯ The present findings establish that cortical atrophy in ALS is highly dependent upon neuropsychiatric and cognitive changes. Previous inconsistent findings of cortical atrophy in ALS likely relate to the inclusion of cognitively affected patients and patients with pure motor ALS.
