The PRIAMO study is a cross-sectional longitudinal observational study aimed at describing epidemiology and evolution of non-motor symptoms (NMS) in patients with different forms of parkinsonism recruited in 55 Italian centres and evaluated over 24 months. In this paper, we are reporting prevalence and clinical characteristics of NMS in patients with atypical and secondary parkinsonism. Out of 1307 consecutive patients with a diagnosis of parkinsonism, 83 patients had vascular parkinsonism (VP), 34 had multiple system atrophy (MSA), 30 had progressive supranuclear palsy (PSP), 14 had dementia with Lewy bodies (DLB) and 11 had corticobasal degeneration (CBD). MSA and DLB had the highest number of NMS domains and symptoms, respectively. Gastrointestinal symptoms, pain, urinary problems and postural instability due to orthostatic hypotension were most frequent in MSA. Sleep disturbances were also common with a prevalence of approximately 70% in all diagnostic groups but CBD (36%). Psychiatric symptoms and attention and memory impairment were frequently observed in all diagnoses but were most prevalent among DLB patients, whereas the prevalence of skin and respiratory disorders was rather low in all forms, ranging between 10 and 30%. Atypical parkinsonism patients also reported a low QoL, with no significant differences among the different forms, whereas PD and VP patients had a better QoL.
