CIRRHOSIS CAN CAUSE PARKINSON'S DISEASE SYMPTOMS

Metabolic Brain Disease [2012] Oct 20 [Epub ahead of print] (R.F. Butterworth) Complete abstract

Acquired hepatolenticular degeneration is also known as "Parkinsonism in cirrhosis". Estimates of the prevalence of Parkinsonism in cirrhosis have been reported as high as more than 20 %. Cirrhosis is due to chronic liver disease. For more information go to Cirrhosis. The cause of Parkinsonism in cirrhosis has been attributed to manganese deposition in the basal ganglia, leading to dysfunction of the dopaminergic system. Blood and cerebrospinal fluid manganese concentrations were several times above the reference range.

There is evidence of damage to, or dysfunction of, dopamine transporters and dopamine receptors. In many patients L-Dopa and dopamine agonists can be beneficial. Liver transplantation is usually effective. Parkinsonism in cirrhosis is characterized by symptoms including hypokinesia, dystonia and rigidity that are rapidly progressive. Typical features included rapid progression over months, symmetric akinetic-rigid syndrome, postural but not resting tremor, and early postural and gait impairment. Neuropsychiatric manifestations were minimal. For a printable version of this article click here.

ODM-101 FOUND TO BE MORE EFFECTIVE THAN STALEVO

ODM-101, a new L-dopa product currently being developed by Orion for the treatment of Parkinson's disease, has successfully completed Phase II Proof of Concept trial. The key results indicate that ODM-101 was more effective than Stalevo in the treatment of advanced Parkinson's Disease.

Stalevo is a standard drug for advanced Parkinson's patients experiencing end-of-dose wearing-off symptoms associated with L-dopa therapy. Stalevo is an enhanced L-dopa treatment containing three active substances in one tablet : L-dopa and the enzyme inhibitors entacapone and carbidopa. For more information go to Stalevo. Orion do not detail in which way ODM-101 and Stalevo are chemically different.

The study included more than 100 patients in Europe. The Principal Investigator said "This phase II study demonstrated that ODM-101 has potential to be significantly more effective than Stalevo in the daily treatment of Parkinson's disease patients with response fluctuations. ODM-101 reduced time periods during the day when patients do not have adequate treatment response. These benefits were possible without an increase in troublesome involuntary movements (dyskinesia)."

PARKINSON'S DISEASE, SECOND EDITION

Ronald F. Pfeiffer (Editor), Zbigniew K. Wszolek (Editor), Manuchair Ebadi (Editor)

Publisher's description : In recent years, considerable advances have been made in our knowledge and understanding of Parkinson's disease (PD). In particular, there has been an explosion of information regarding genetic contributions to the etiology of PD and an increased awareness of the incidence and importance of the non-motor features of the disease. Theories regarding the pathogenesis and pathophysiology of PD have also been refined, and new treatment modalities and advances have been implemented. Reflecting these changes, this second edition features new chapters devoted to genetic aspects of PD, non-motor features of the disease, as well as aspects of the pathophysiology, pathogenesis, and treatment of PD.

SEASONAL EFFECT ON DOPAMINE

Neuroscience Letters [2102]  Oct 2 [Epub ahead of print] (Kaasinen V, Jokinen P, Joutsa J, Eskola O, Rinne JO) Complete abstract

The formation of dopamine, the substance whose deficiency causes Parkinson's Disease, has been found to vary according to the season of the year, and the season in which somebody is born. This means that the likelihood of Parkinson's Disease symptoms are likely to change according to the season of the year, and in which season somebody was born

The capacity to produce dopamine was found to be higher in people with Parkinson's Disease during the autumn (fall) and the winter. The potential was 15% higher during autumn (fall) and winter than it was during spring and summer. Dopamine levels were also affected by which season people were born in. People born during winter and spring were found to have a clearly higher capacity to produce dopamine compared to people born during the summer and autumn (fall). Therefore, the season in which somebody is born could cause Parkinson's Disease to be more or less likely. There was also evidence of season of birth effects in several neuropsychiatric disorders.
