Tremor is the most common initial symptom and one of the cardinal features of Parkinson's disease. Mild tremor causes only minimal disability, but severe tremor causes more significant disability and distress for the patient than rigidity and/or bradykinesia. Anticholinergic agents, levodopa/DCI and dopamine agonists are most common and beneficial in parkinsonian tremor, but efficacies of these medications are variable among patients. Rigidity and bradykinesia are more responsive to levodopa/DCI therapy than tremor. Clozapine is an atypical neuroleptic agent, not on the market in Japan, and has been reported to decrease or ameliorate parkinsonian tremor through the studies of open label and double blind crossover as a new drug for parkinsonian tremor.

We report a case of Parkinson's disease (PD) diagnosed by REM sleep behavior disorder (RBD). The patient was a 68-year-old man. On admission, rigidity in the left upper and lower extremities, bradykinesia, and gait disturbance were noted. In addition, polysomnography revealed REM sleep without atonia (RWA), and a diagnosis of untreated PD associated with RBD was made. Polysomnographic data showed that REM density decreased and RWA tended to increase after administration of a combination of L-DOPA and DCI (L-DOPA/DCI). Thus, we considered that the pathophysiological mechanism of RBD in this case was based not only on the dysfunction of the brainstem mechanism of RWA, but also on the impairment of dopaminergic neuron.

A 69-year-old woman was admitted to our hospital due to an interval form of carbon monoxide (CO) poisoning one month after acute CO poisoning. On admission, she had disorientation, memory disturbance, apathy, masked face, muscle rigidity, bradykinesia and parkisonian gait. An MRI (FLAIR image) revealed high signal intensity lesions in the bilateral globus pallidus and the white matter of the frontal lobe. Hyperbaric oxygen (HBO) therapy at 2 atmospheres for 60 min was given every day, in addition to citicoline, levodopa/DCI and selegiline hydrochloride. Cognitive disturbance and parkinsonism gradually decreased, and abnormal signals in the bilateral globus pallidus and the cerebral white matter were attenuated after the treatment. Neuropsychiatric abnormalities except for a slight gait disturbance disappeared one and a half month after starting the treatment. In addition to HBO therapy, administration of citicoline, lovodopa and selegiline may be useful in the case of the interval form of CO poisoning.

Rasagiline (Azilect) is a potent, highly selective and irreversible inhibitor of monoamine oxidase type B of the second generation. Rasagiline is indicated for the treatment of Parkinson's disease (PD) as monotherapy (without levodopa) or as adjunct therapy (with levodopa) in patients with end of dose fluctuations. The efficacy and tolerability of rasagiline has been demonstrated in large-scale, controlled clinical studies in patients with early PD as well as with more advanced PD. This multicentred post-marketing observational study included an investigation of the efficacy and tolerability of rasagiline in a large patient population under conditions of the daily routine in neurologic practice with a special attention on the collection of data regarding a patients' subjective evaluation of quality of life. A total of 754 patients with Parkinson's disease were enrolled, 545 of the patients (63% male patients, mean age 68 years, mean duration of PD 6 years, Hoehn & Yahr stage II to III in 69% of the patients) started rasagiline 1 mg/day as adjunct therapy for up to 4 months. The PD symptoms were rated by the physicians using the Columbia University Rating Scale (CURS) and the clinical fluctuations subscale of the Unified Parkinson's Disease Rating Scale (UPDRS, part IV B). Different aspects of quality of life were rated by the patients using the self-rating Parkinson's Disease Questionaire (PDQ-39). In addition, patients documented the number of hours spend in the OFF-state in "24-hour" home diaries prior to each of the assessment visits. During the treatment period rasagiline was most frequently co-administered with levodopa/DCI (81.7%) and/or dopamine agonists (65.8%). The mean treatment duration was 117.4 (+/-36.4) days, during which PD medication remained unchanged in 86.6% of the cases. The improvement rates in each of the CURS items ranged between 31.1% to 48.4% and the total score was reduced by 22% under the therapy of rasagiline. In the motor part (tremor, rigidity, bradykinesia) the total score was reduced from 6.2 to 4.8, within the other items from 14.7 to 11.5. The proportion of patients without OFF-periods increased from 33.3% to 49.5%. Determined from "24-hours" home diaries, time spend in the OFF-state during wake time decreased from 120 minutes to 45 minutes. In all 8 aspects of quality of life rated by the patients an reduction of the disability could be documented. The PDQ-39 total score was reduced from 36.4 by 7.3 points (20.1%). In total, 29 of the 545 patients who received rasagiline as combination therapy had switched directly from previous combination therapy with selegiline. In this subgroup CURS total score improved from 17.0 to 12.9 points during treatment. The proportion of patients without OFF-periods increased from 36% to 48% and the daily time spent in the OFF-state was reduced from 45 minutes to 30 minutes. The PDQ-39 total score improved by 6.5 points (22.2%). All in all, adverse events were reported by 8.4% of the patients. In conclusion this post-marketing observational study has shown that in patients with pre-existing combination therapy the add-on medication of rasagiline resulted in improvements of motor and non-motor functions. Furthermore, motor complications were significantly reduced and led to an improved quality of life in the self-estimation of the patients. This also applies to those patients with selegiline pre-treatment.
