Corticobasal syndrome (CBS) and progressive supranuclear palsy (PSP) are sporadic atypical parkinsonian disorders associated with 4-repeat tauopathies. These neurodegenerative conditions closely overlap in their clinical information, pathology, genetic risk factors ; therefore, it is difficult to accurately diagnose CBS PSP. Recently, an unsupervised machine-learning technique, called Subtype S...

Postencephalitic parkinsonism has been considered unique among disorders with parkinsonian features because it is believed to have a unitary etiology associated with the virus that presumably caused encephalitis lethargica. Careful analysis of the historical record, however, suggests that this relationship is more complex than commonly perceived. In most cases, the diagnosis of acute encephalit...

Background. Nonmotor symptoms particularly olfactory dysfunction, RBD, depression, hallucinations, and constipation are currently not included in the typical clinical criteria for diagnosing Lewy body Parkinsonian disorders (LBPD). The aim of this study is to determine the diagnostic value of nonmotor symptoms in patients presenting with Parkinsonism and tremor. Methods. All new patients seen b...

OBJECTIVE Parkinson's disease (PD) is a progressive neurological disorder characterised by a large number of motor and non-motor features that can impact on function to a variable degree. This review describes the clinical characteristics of PD with emphasis on those features that differentiate the disease from other parkinsonian disorders. METHODS A MedLine search was performed to identify s...

Background: Quantitative and objective neurophysiological assessment can help to define the predominant phenomenology provide diagnoses with prognostic therapeutic implications. We evaluated retrospectively indications final of movement disorder evaluations in a specialized disorders centre. Methods: Reports from 2003 11/2021 were reviewed. The classified according phenomenology, diagnosis each...
