Human immunodeficiency virus (HIV) infection can cause variable movement disorders, including parkinsonism. HIV-related parkinsonism usually responds well to highly-active antiretroviral therapy (HAART), suggesting a possible reversible dysfunction of the dopaminergic system. We report the case of a 42-year-old man who presented with rapidly progressive symmetric parkinsonism, cognitive decline...

Parkinsonism, as a gradually progressive disorder, has a prodromal interval during which neurodegeneration has begun but cardinal manifestations have not fully developed. A systematic direct assessment of this interval has never been performed. Since patients with idiopathic REM sleep behaviour disorder are at very high risk of parkinsonism, they provide a unique opportunity to observe directly...

Objective NA. Background Autoimmune Encephalitis is an inflammatory condition of the brain due to antibodies against onconeuronal proteins. Paraneoplastic Parkinsonism very rare. We report first case AMPA receptor encephalitis presenting with symptoms parkinsonism, atypical presentation a rare entity. Design/Methods Results A 71-year-old female multiple comorbidities presented in state stupor c...

RESULTS Trauma to the peripheral nervous system can cause various movement disorders including dystonia, tremor and parkinsonism. Most patients with peripherally-induced parkinsonism develop symptoms that extend beyond the original site of injury, suggesting involvement of the central nervous system, possibly through reorganization in response to altered peripheral input. Most patients with per...

Symptomatic parkinsonism secondary to ipsilateral lesion is rarely reported. Although the contribution of the contralateral lesions was assumed in some cases, the pathomechanism remains undetermined. Herein we report a patient with a subdural hematoma, who developed parkinsonism in the ipsilateral hemibody. Structural and functional imaging suggests the contralateral dopaminergic dysfunction as...

An intracranial tumor is a rare cause of secondary parkinsonism. Our patient presented to our clinic for recently-developed asymmetric parkinsonism without pyramidal signs. However, a meningioma located in the sphenoidal ridge was identified upon imaging studies. This case suggests that additional causes should be considered when approaching patients with parkinsonism and that imaging studies c...

A case of parkinsonism associated with neurosyphilis, which improved markedly after appropriate treatment, is described. Although neurosyphilis is a rare cause of parkinsonism, it should be considered when parkinsonism appears in the 30-50-year age group, particularly if other anomalous neurological findings are present. Adequate therapy may improve the patient's condition and prevent further p...
