ABSTRACTParkinsonism is defined as the presence of bradykinesia and at least one of the following: rest tremor, rigidity, or postural instability. Most of the parkinsonism seen at neurological centers represent Parkinson’s disease (PD). Differential diagnosis can be complicated, particularly in early stages when features of PD may overlap with those seen in other movement disorders. Atypical parkinsonian disorders are a group of clinical syndromes with atypical features beyond the classic PD. Progressive supranuclear palsy (PSP), multiple system atrophy (MSA), dementia with Lewy bodies (DLB) and corticobasal degeneration (CBD) are the most prevalent. They all share parkinsonian features which make early diagnosis a challenge for the neurologist. However, it is important to guide management and predict prognosis.
