We aim to define neuropsychological phenotypes in MS based on cognitive function, depression and fatigue.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In this cross\u2010sectional study, we collected clinical and neuropsychological data for 600 MS patients. Neuropsychological assessments included Brief International Cognitive Assessment for MS (BICAMS), Beck Depression Inventory (BDI\u2010II) and Modified Fatigue Impact Scale (MFIS). We employed a latent profile analysis (LPA) to unveil latent neuropsychological profiles in MS patients, clustering individuals in unobserved groups, and we compared clinical and MRI features between groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>LPA identified five neuropsychological phenotypes: Normal neuropsychological phenotype, with normal cognitive and neurobehavioral scores; Isolated cognitive impairment, showing mild reduction in BICAMS scores; Isolated neurobehavioral impairment, showing increased BDI\u2010II and MFIS scores; Mild neuropsychological impairment, showing mildly reduced BICAMS scores, and mildly increased BDI\u2010II and MFIS scores; Severe neuropsychological impairment, showing severely reduced BICAMS scores, and great increase in BDI\u2010II and MFIS scores vs patients with normal neuropsychological phenotype.<\/jats:p><jats:p>Relapsing\u2010onset and paediatric\u2010onset patients are more likely in the normal neuropsychological phenotype and isolated cognitive impairment class. Patients with severe neuropsychological impairment showed lower cortical grey matter, thalamic, amygdala, pallidum and putamen volume compared with those with isolated neurobehavioral impairment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>We identified five neuropsychological phenotypes in patients with MS that showed distinct clinical and radiologic features, as from different stages of the disease pathology accrual. Clinical and MRI features may help distinguishing patients requiring closer monitoring of cognitive or neurobehavioral symptoms.<\/jats:p><\/jats:sec><jats:sec><jats:title>Disclosures<\/jats:title><jats:p>Antonio Luca Spiezia, Fabrizia Falco, Federica Lamagna, Martina Eliano, Valerio Nicolella, Antonio Esposito and Cristina Di Monaco have nothing to disclose.
