The aim of the study was to investigate the efficacy of homemade tolcapone in treatment of patients with Parkinson's disease (PD). Eighty patients with PD were subjected to randomized, double-blind, placebo-controlled and parallel-group study. PD patients were randomly divided into the tolcapone treatment group (41 cases) and placebo group (39 cases). Each patient received 1 pill of tolcapone o...

Background: Experimental evidence supports a preventative role for non-steroidal anti-inflammatory drugs (NSAIDs) in Parkinson’s disease (PD). Methods: We investigated associations between use of aspirin, nonaspirin NSAIDs, and acetaminophen and PD in a large population-based casecontrol study using Danish health and pharmacy registries. We identified 1,931 PD cases reported in hospital or outp...

Research derived from non-invasive brain imaging modalities has been used to explore the spatial and temporal organization of the neural systems supporting human behavior and causing brain disorders. Imaging modalities of interest include positron emission tomography, event-related potentials, electro-and magnetoencephalography, and magnetic resonance imaging (MRI). In this talk, we will presen...

Parkinson's disease (PD) is a progressive neurodegenerative disorder resulting in part from loss of nigrostriatal dopamine (DA) neurons. Treatments act only to relieve symptoms. It is therefore essential to develop treatments that slow or reverse the neurodegenerative process. Here, I explored exercise as a potential treatment against a 6-hydroxydopamine (6-OHDA) rat model. 6-OHDA causes select...

Recently a novel method for the preparation of (18)F-labeled arenes via oxidative [(18)F]fluorination of easily accessible and sufficiently stable nickel complexes with [(18)F]fluoride under exceptionally mild reaction conditions was published. The suitability of this procedure for the routine preparation of clinically relevant positron emission tomography (PET) tracers, 6-[(18)F]fluorodopamine...

Mesencephalic-diencephalic dopaminergic (mdDA) neurons control motor, sensorimotor and motivated behaviour and their degeneration or abnormal functioning is associated with important pathologies, such as Parkinsons disease and psychiatric disorders. Despite great efforts, the molecular basis and the genetic factors differentially controlling identity, survival and vulnerability to neurodegenera...

BACKGROUND Dizziness is a frequent complaint of patients with Parkinson's disease (PD), and orthostatic hypotension (OH) is often thought to be the cause. We studied whether benign paroxysmal positional vertigo (BPPV) could also be an explanation. AIM To assess the prevalence of benign paroxysmal positional vertigo in patients with Parkinson's disease, with and without dizziness. METHODS 30...

Despite Medicare data showing that about 25% of people with Parkinson’s disease (PD) reside in nursing homes, many practitioners may not have a lot experience diagnosing and managing this condition. As Nora Reznickova, MD, geriatrician at Colorado Permanente Medical Group Boulder, said, “Starting the differential diagnosis, aren’t necessarily comfortable PD patients. They feel like they necessa...
