The effect of age of onset of PD on risk of dementia

Background Dementia occurs in the majority of patients with Parkinson’s disease (PD). Late onset of PD has been reported to be associated with a higher risk for dementia. However, age at onset (AAO) and age at baseline assessment are often correlated. The aim of this study was to explore whether AAO of PD symptoms is a risk factor for dementia independent of the general effect of age. Methods Two community-based studies of PD in New York (n = 281) and Rogaland county, Norway (n = 227) and two population-based groups of healthy elderly from New York (n = 180) and Odense, Denmark (n = 2414) were followed prospectively for 3–4 years and assessed for dementia according to DSM-IIIR. All PD and control cases underwent neurological examination and were followed with neurological and neuropsychological assessments. We used Cox proportional hazards regression based on three different time scales to explore the effect of AAO of PD on risk of dementia, adjusting for age at baseline and other demographic and clinical variables. Findings In both PD groups and in the pooled analyses, there was a significant effect of age at baseline assessment on the time to develop dementia, but there was no effect of AAO independent of age itself. Consistent with these results, there was no increased relative effect of age on the time to develop dementia in PD cases compared with controls. Interpretation This study shows that it is the general effect of age, rather than AAO that is associated with incident dementia in subjects with PD. Received in revised form: 22 December 2005

Standards of instrumentation of EMG

Standardization of Electromyography (EMG) instrumentation is of particular importance to ensure high quality recordings. This consensus report on “Standards of Instrumentation of EMG” is an update and extension of the earlier IFCN Guidelines published in 1999. First, a panel of experts in different fields from different geographical distributions was invited to submit a section on their particular interest and expertise. Then, the merged document was circulated for comments and edits until a consensus emerged.The first sections in this document cover technical aspects such as instrumentation, EMG hardware and software including amplifiers and filters, digital signal analysis and instrumentation settings. Other sections cover the topics such as temporary storage, trigger and delay line, averaging, electrode types, stimulation techniques for optimal and standardised EMG examinations, and the artefacts electromyographers may face and safety rules they should follow. Finally, storage of data and databases, report generators and external communication are summarized.     

Effects of prevention of afferentation of the development of the chick optic lobe

BONDY, S. C., M. E. HARRINGTON AND C. L. ANDERSON. Effects of prevention of afferentation on the developmentof the chick optic lobe. BRAIN RES. BULL. 3(5) 411–413, 1978.—The effects of unilateral extirpation of the right optic cup of the three-day incubated chick embryo upon the rate of synthesis and the stability of DNA in the non-innervated optic lobe, have been studied. This surgical procedure prevents innervation of the optic lobe contralateral to the removed eye, while the other optic lobe is normally innervated by retinal ganglion cells of the remaining eye. At the 20th day of incubation, the DNA content of the non-innervated lobe was below that of the paired lobe receiving normal innervation. This deficiency of cell number was caused by two events; death of an excess number of neurons formed early in embryogenesis and a reduced rate of glial proliferation in the later stages of incubation.     

Release of endogenous catecholamines from slices of hypothalamus of rats

The release of endogenous catecholamines from superfused slices of rat hypothalamus was studied under basal conditions and during release evoked by 40 mM K⁺. Catecholamines in superfusates, and in extracts of the tissue after stimulation, were isolated by column chromatography and quantitated by liquid chromatography with electrochemical detection. Norepinephrine (NE) was not consistently demonstrable in superfusate collected under basal conditions, but 40 mM K⁺ caused the release of from 2 to 4 ng/g of tissue per min. The addition of cocaine to the superfusate caused increases in basal and evoked release of NE. Epinephrine (E) could be measured in superfusates of slices from male but not female rats and then only when cocaine was added to the superfusate. Accordingly, the concentration of E in hypothalamus was greater in male rats than in female rats. Dopamine (DA) was not consistently measurable in the spontaneous overflow from slices either in the presence or absence of cocaine. K⁺-evoked release of DA could be demonstrated in slices from female rats. The addition of cocaine increased the evoked release of DA from slices from both sexes. Corticosterone, added to cocaine, had no effects on the efflux of any of the catecholamines. The experiments suggest that neuronal reuptake of all catecholamines is very efficient in the hypothalamus both under basal conditions and during evoked release.     

帕金森病运动症状进展分析

目的分析帕金森病(PD)患者运动症状进展特点。方法采用PD统一评分量表(UPDRS)Ⅲ对912例PD患者进行评估。结果与病程1年的患者比较,除病程1~2年的患者外,其他病程患者的UPDRSⅢ评分、强直分、姿势或步态异常分、轴性症状总分、言语分、步态分显著升高(均P0.05),病程5~6年及14年患者的震颤分,病程5~6年、7~8年、9~13年、14年患者的运动迟缓分、姿势分显著升高(P0.05~0.01)。轴性症状进展速度高于UPDRSⅢ评分。结论 PD患者病程早期UPDRSⅢ评分进展快,震颤症状进展独立于其他症状,轴性症状评分较UPDRSⅢ更敏感地反映疾病加重趋势。     

Frequency of accumulation of filaments in adaxonal cytoplasm of Schwann cells of myelinated fibers of rat spinal roots

Summary The frequency of accumulation of 6-nm filaments in the adaxonal cytoplasm of Schwann cells in the 6th lumbar dorsal and ventral roots was evaluated in 4-, 8-, 26- and 45-week-old Sprague-Dawley rats. The frequency was higher in 4- and 8-week-old (growing) rats than in 26- and 45-week old (mature) rats, and also higher in ventral than in dorsal roots in 4-, 8- and 26-week old rats. There were no clusters on certain groups of myelinated fibers according to the size of transverse axonal area, in both the ventral and dorsal roots. Therefore, this accumulation may reflect certain functions of the adaxonal cytoplasm of Schwann cell during natural growth and maturation of the axon and myelin sheath.

Function of circle of Willis

Nearly 400 years ago, Thomas Willis described the arterial ring at the base of the brain (the circle of Willis, CW) and recognized it as a compensatory system in the case of arterial occlusion. This theory is still accepted. We present several arguments that via negativa should discard the compensatory theory. (1) Current theory is anthropocentric; it ignores other species and their analog structures. (2) Arterial pathologies are diseases of old age, appearing after gene propagation. (3) According to the current theory, evolution has foresight. (4) Its commonness among animals indicates that it is probably a convergent evolutionary structure. (5) It was observed that communicating arteries are too small for effective blood flow, and (6) missing or hypoplastic in the majority of the population. We infer that CW, under physiologic conditions, serves as a passive pressure dissipating system; without considerable blood flow, pressure is transferred from the high to low pressure end, the latter being another arterial component of CW. Pressure gradient exists because pulse wave and blood flow arrive into the skull through different cerebral arteries asynchronously, due to arterial tree asymmetry. Therefore, CW and its communicating arteries protect cerebral artery and blood–brain barrier from hemodynamic stress.
