Introduction: Methanol is a toxic material and is found as an ingredient of many products, such as anti freezes and washer fluid. Acute poisoning is a rare accidental or suicidal intoxication or occurs after ingestion of alcohol .Methanol poisoning can cause severe metabolic acidosis , neurologic dysfunction, visual loss, parkinsonism, and death. Basal ganglia necrosis, and subcortical white ...
BACKGROUND Atypical antipsychotic agents are thought to be less likely than older typical agents to produce parkinsonism. This has not been well documented. We compared the risk of development of incident parkinsonism among older adults dispensed atypical relative to typical antipsychotics. METHODS Retrospective cohort study of all adults 66 years and older in Ontario. We used Cox proportiona...
BACKGROUND The best data on prognosis comes from population-based incident cohorts but few such cohorts exist for Parkinson's disease and atypical parkinsonism. METHODS The PINE study is a prospective follow-up study of an incident cohort of people with degenerative or vascular parkinsonism and age-sex matched controls. Participants have annual follow-up from diagnosis until death with review...
BACKGROUND Differentiating psychogenic parkinsonism from neurodegenerative Parkinson's disease (PD) with psychogenic features is a diagnostic challenge. CASE REPORT We report a detailed longitudinal clinical description of three cases presenting with suspected psychogenic parkinsonism. Dopamine transporter single-photon emission computed tomography (DAT-SPECT) was used as a supplemental diagn...
Parkinsonism is a common complication of neuroleptic drug use; however, the pathophysiology of the persistence of parkinsonian symptoms after withdrawal of neuroleptic drugs is poorly understood. Twenty patients with neuroleptic induced parkinsonism were studied by high field MRI. Persistence of symptoms was associated with different findings depending on the age of the patients--namely, putami...
BACKGROUND We tested the hypothesis that harm avoidance, a trait associated with behavioral inhibition, is associated with the rate of change in parkinsonism in older adults. METHODS At baseline harm avoidance was assessed with a standard self-report instrument in 969 older people without dementia participating in the Rush Memory and Aging Project, a longitudinal community-based cohort study....
BACKGROUND AND PURPOSE Asymmetric presentation of clinical feature in parkinsonism is common, but correlatable radiologic feature is not clearly defined. Our aim was to evaluate 3T susceptibility-weighted imaging findings for differentiating parkinsonism-predominant multiple system atrophy from idiopathic Parkinson disease, focusing on putaminal changes and lesion asymmetry. MATERIALS AND MET...
Parkinsonism in cerebrotendinous xanthomatosis (CTX) is rare. There are no published studies with imaging findings of dopamine transporter using (99m)Tc-[2-[[2-[[[3-(4-chlorophenyl)-8-methyl-8-azabicyclo [3,2,1] oct-2-yl] methyl] (2-mercaptoethyl) amino] ethyl] amino]-ethanethiolato(3-)-N2,N2,S2,S2]oxo-[1R-(exo-exo)] ((99m)Tc-TRODAT-1) SPECT in CTX patients. This report is on the clinical detai...
Background: Differentiating psychogenic parkinsonism from neurodegenerative Parkinson’s disease (PD) with psychogenic features is a diagnostic challenge. Case report: We report a detailed longitudinal clinical description of three cases presenting with suspected psychogenic parkinsonism. Dopamine transporter single-photon emission computed tomography (DAT-SPECT) was used as a supplemental diagn...
Haloperidol was used in 12 patients in an attempt to improve l-dopa induced dyskinesias. In eight patients any improvement in dyskinesias was associated with increased Parkinsonism. In four patients the dyskinesias initially improved without clinical deterioration. Within several weeks, however, the disability due to Parkinsonism increased in these four patients as well. These observations sugg...
