ABSTRACT
BACKGROUND: An inverse association between cigarette smoking and the risk of idiopathic PD has been found in many epidemiologic studies. The therapeutic and possible neuroprotective effects of nicotine formulations on parkinsonian symptoms are controversial. METHODS: In a 12-week, randomized, double-blind, placebo-controlled trial, the efficacy and tolerability of transdermal nicotine patches as an add-on treatment for cardinal symptoms were evaluated in 32 nonsmoking patients with PD. After a 1-week run-in phase, patients were randomized to receive nicotine patches (containing 17.5 mg nicotine in the first and 35.0 mg nicotine in the second and third weeks) or identically appearing placebo patches. After this treatment, 3 weeks without patch application followed. The same blinded examiner assessed the patients with the Columbia University Rating Scale, the Webster scale, the Schwab-England scale, a timed walking test, with an instrumental test for fine motor skills and hand tremor, and with the Hamilton Depression Scale. RESULTS: No significant drug effects between both groups were observed in any of the scores and quantitative tests. Side effects were mild and comparable in frequency between both groups. CONCLUSIONS: With the dosage and the period of treatment chosen, transdermal nicotine patches are not effective as an add-on treatment for symptoms of PD.

In a prospective series of 34 incident patients with primary cervical dystonia (CD), 6 showed clinical or radiological signs of cervical radiculopathy (RP) or myelopathy (MP) during the course of their movement disorder. Age at onset in these patients was in the range reported for pure spondylotic cervical RP without an accompanying movement disorder. Radiologically, spondylosis was mild in 1 case and absent in 2 cases. The intervals between onset of CD and RP were shorter than in literature reports of RP/MP in dystonic-athetotic patients of cerebral paresis. Clinically, RP/MP in patients with CD mostly appears at mid-cervical levels, whereas cases with cerebral paresis are more frequently affected at higher cervical segments. We propose that RP/MP does not occur more frequently in CD than in pure spondylotic cervical RP.

OBJECTIVE: To evaluate the opinions and attitudes of young patients with Parkinson's disease (PD) towards possible presymptomatic and prenatal genetic testing for their illness. BACKGROUND: With progress in understanding of the genetic component in the etiology of PD, presymptomatic genetic testing may become available in subgroups of patients. METHODS: During a survey on sociodemographic and risk factors 111 PD patients (mean age 45 years: mean age at PD onset 36 years) were given a questionnaire with six items about possible presymptomatic and prenatal genetic testing. RESULTS: Fifty-seven patients (5196) had knowledge about presymptomatic and prenatal testing. Eighty patients (72%) would take a presymptomatic test, if they had an autosomal dominant form of PD and if the test were available. The most Important reasons given for taking the test were planning of partnership (40%) and family (48%). When being identified as a carrier of a presumed "Parkinson gene", 78 patients (70%) would decide not to have children. Sixty-three patients (57%) would choose to have prenatal testing. Attitudes were largely independent of sociodemographic and disease variables. CONCLUSIONS: When addressed as hypothetical persons at genetic risk, young patients with PD support possible presymptomatic genetic testing and, to a lesser extent, prenatal testing. Attitudes and reasons to participate in such hypothetical testing do not grossly differ from those of at-risk persons in established single-gene autosomal dominant disorders of late onset.

OBJECTIVES: It has been hypothesized that the dopaminergic deficit of older patients with Parkinson's disease (PD) is associated with a reduction in the dopamine-dependent personality trait "novelty seeking". It is unknown whether this may also be found in younger patients with PD whose dopaminergic deficit is considered to be purely motor. MATERIAL AND METHODS: We interviewed 122 patients below 51 years of age and 122 age- and sex-matched healthy controls with regard to clinical and sociodemographic data. Both groups had to fill out the Tridimensional Personality Questionnaire (TPQ) of Cloninger. Neuropsychological testing of formal intelligence and depression was also applied. RESULTS: "Novelty seeking" was not different between both groups. Patients were more often depressed than controls, explaining their difference in "harm avoidance" on the TPQ. "Persistence", a sub-scale of the third TPQ dimension "reward dependence", was significantly higher in patients. Neither sex, nor age, nor educational status were correlated with one of the three personality traits. CONCLUSIONS: The higher rate of depression explains our finding of more "harm avoidance" among young PD patients. According to a literature review the choice and performance of controls is crucial whether personality traits in PD patients may be assessed as abnormal.

Answers from a multiple choice questionnaire on the opinions about public sexual attitudes, on emotion from personal sexual practice, on personal sexual function, and on general health perception were compared between 121 patients with Parkinson's disease (mean age 45 years) and 126 age and sex matched community derived controls. Patients were more dissatisfied with their present sexual functioning and relationship, and perceived their general health as poorer than the controls, whereas opinions about public sexual attitudes were only marginally different. No differences were found for sexual function. Further analysis showed that the perception of sexual functioning and general health in younger patients with Parkinson's disease is considerably influenced by depression and state of unemployment.
