Cognitive Functioning in People With Myasthenia Graivs: Impact on Daily Life Activities, Work, Disability and Quality of Life

Previous literature findings provide contradictory indications about presence of cognitive impairment in patients with MG, but patients experience different degree of limitations in ADLs, disability and QoL which might not be entirely understood on the basis of neuromuscular symptoms. We therefore aimed to address the potential impact of cognitive impairment.

MYCOG is a monocentric, cross-sectional and observational study which primarily aims to estimate the prevalence of cognitive difficulties, measured with Global Examination of Mental State (GEMS), in patients with MG treated at Besta Institute. Secondary aims include: a) assess the degree to which cognitive difficulties are associated to work impairment (measured with WPAI-GH), limitations in ADL (measured with MG-ADL), symptoms of anxiety and depression (measured with HADS), fatigue (measured with FSS), disability and QoL (measured with MG-DIS and MG-QOL15); b) assess whether patients with different MG types (ocular, generalized, bulbar, pharmacological remission and clinical stable remission) show different degrees of cognitive impairment; c) assess whether patients with different MG antibody profiles (AChR, MuSK, Double Negative) show different degrees of cognitive impairment; d) assess whether patients under different MG-specific pharmacological treatments (piridogstigmine, steroids, other therapies such as immunemodulators) show different degrees of cognitive impairment.
