To investigate whether 24 months of idebenone may reduce the progression from Prodromal Parkinson disease (PPD) to Parkinson disease (PD).
Number of people suffered from Parkinson disease (PD) is increasing every year. Contemporary medication has little neuroprotective effect, which may due to delayed treatment as over 50% neurons have lost when clinical diagnosed PD emerges. The concept of Prodromal Parkinson disease (PPD) is emphasized as it has become evident that there are several risk and clinical markers may occur years before the cardinal motor symptoms which allow clinical diagnosis. Rapid eye movement (REM) sleep behavior disorder and olfactory dysfunction are the most common PPD, and more than one third of patients may progress to PD and other neurodegenerative diseases. Mitochondrial injury is one of the pathogenesis of PD. Thus we design this trial to investigate whether idebenone, potent coenzyme Q10 analogue, could protect PPD develops into PD.

Idebenone improves energy metabolism similarly to Coenzyme Q10, which is effective in migraine prophylaxis. The investigators compared idebenone (90 mg/day, 270 mg/day) and placebo in 180 ...
The purpose of this study is to compare the efficacy of two (2) different doses of idebenone with that of a placebo over a one month period on cerebral lactate concentration as measured by...
In this proposed study, the investigators aim to build up a large cohort of Rapid eye movement sleep behavior disorder (RBD) to study the etiology and risk factors of neurodegeneration.

The neurophysiological hallmark of REM sleep behavior disorder (RBD) is loss of atonia during REM sleep. Indeed, signs and symptoms of neurodegeneration can occur after years, even decades, from its b...
The present study was undertaken to evaluate the cognitive profile of Parkinson's disease (PD) patients with REM sleep behavior disorder (RBD) and to correlate with the clinical stage and polysomnogra...
A disorder characterized by episodes of vigorous and often violent motor activity during REM sleep (SLEEP, REM). The affected individual may inflict self injury or harm others, and is difficult to awaken from this condition. Episodes are usually followed by a vivid recollection of a dream that is consistent with the aggressive behavior. This condition primarily affects adult males. (From Adams et al., Principles of Neurology, 6th ed, p393)
Abnormal behavioral or physiologic events that are associated with REM sleep, including REM SLEEP BEHAVIOR DISORDER.
Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)
A sleep disorder characterized by grinding and clenching of the teeth and forceful lateral or protrusive jaw movements. Sleep bruxism may be associated with TOOTH INJURIES; TEMPOROMANDIBULAR JOINT DISORDERS; sleep disturbances; and other conditions.
A sleep disorder of central nervous system origin characterized by prolonged nocturnal sleep and periods of daytime drowsiness. Affected individuals experience difficulty with awakening in the morning and may have associated sleep drunkenness, automatic behaviors, and memory disturbances. This condition differs from narcolepsy in that daytime sleep periods are longer, there is no association with CATAPLEXY, and the multiple sleep latency onset test does not record sleep-onset rapid eye movement sleep.
