Acute Onset of Parkinsonism With Reversible Course After H1N1 Vaccination: Insight From a Young Lady
“To the Editor: Parkinsonian symptoms can be induced by acute encephalitis, syphilis, malaria, poliomyelitis, and sudden carbon monoxide poisoning.1,2 In this report, a 17-year-old girl had Parkinson’s disease (PD) symptoms after a flu shot. So far, this is the first vaccine-related disorder that mimics PD. Our experience has shown that some parkinsonism can be cured with accurate diagnosis and appropriate treatment.”

Idiopathic Parkinson’s disease(s) may follow subclinical episodes of perivenous demyelination.
“Three case studies of postvaccinal parkinsonism (PVP) demonstrated signs and symptoms identical to conventional diagnostic standards of idiopathic Parkinson’s disease (PD). PVP is a sub-type of acute disseminated encephalomyelitis (ADE) that also includes postinfectious parkinsonism (PIP) and postinfectious encephalomyelitis (PIE).”
The neurotoxicity of environmental aluminum is still an issue
“A 5-year-old boy, with a history of fever beginning 15 days after a vaccination for measles, developed a rigid-akinetic syndrome 3 days after the fever began. A spinal tap obtained 1 week after the onset of fever showed pleocytosis with a monocellular pattern. A CT scan of the head and EEG did not disclose any abnormality. An MRI performed 3 months after the event, however, showed clear-cut evidence of bilateral substantia nigra lesions, suggesting secondary gliosis. The response to levodopa was good, but adverse reactions appeared early. The child is now 7 years old. Bromocriptine, deprenyl, and levodopa have produced a remarkable improvement of the parkinsonian features.”
