Background:
The Global Multiple System Atrophy Registry (GLOMSAR) was established in 2013. It is an online patient-reported contact registry open and free that relies on self-reported diagnosis by the patient or caregiver.
Objectives:
To report the demographics of patients enrolled in GLOMSAR and the results of an ancillary online symptom questionnaire.
Methods:
Patients enrolled in GLOMSAR were invited to complete a custom-designed online questionnaire about disease onset and symptom prevalence.
Results:
At the time of writing, there were 1083 participants in GLOMSAR, of which 33% (365) completed the questionnaire. The onset and frequency of most symptoms was similar to those reported in the literature in physician-reported studies. Some were understudied or not typically associated with multiple system atrophy (MSA), including reduced female sexual sensation (55%), forgetfulness (60%), pseudobulbar affect (37%), olfactory changes (36%), and visual hallucinations (21%).
Conclusions:
Patient-reported studies and ancillary online questionnaires are valid, underused research tools useful to advance our knowledge on understudied MSA features and highlight the patients' voice.
