注意缺陷多动障碍(Attention Deficit/Hyperactivity Disor- der,ADHD)是指一种以注意缺陷、多动、冲动的行为表现为主要特征的精神障碍(APA,1994)。尽管注意缺陷多动障碍是儿童期常见的一种广泛性发展障碍,但很少有随访研究那些儿童期被诊断为ADHD的个体进入成年期(Young,2000)后的情况。成人ADHD的概念于1980年在DSM-Ⅲ中首次得到公认。ADHD成人与儿童一样,均有三种初级特征,包括注意缺陷、活动过多以及冲动等。除了初级特征之外,成人ADHD还存在多种次级特征,包括物质滥用、学习困难、频繁迁居、车祸、监禁、工作记录不稳定以及赌博等。一般认为,30%至50%的儿童ADHD症状会持续进入成年期。Barkley认为追踪研究表明,持续症状学评估的变化为10%到70%,这取决于研究类型及研究者对这一障碍的定义。  相似文献

近年来,儿童注意缺陷多动障碍(ADHD)的研究在国内外受到广泛关注.美国儿科协会临床指南指出学龄儿童ADHD的患病率为4%~12%,是一种最常见的儿童心理行为疾病[1].我国选用DSM-Ⅳ的注意缺陷多动障碍诊断标准,近年调查学龄儿童检出率为3.94%~6.3%[2-4],调查数据普遍低于国外的数据,但总体呈上升趋势.儿童ADHD核心症状为注意力不集中、多动与冲动,它的病因目前仍不清楚,一般认为是由遗传和环境因素引起的一种心理行为性疾病.近年经许多回顾研究表明,ADHD儿童的不良行为与家庭环境因素和养育方式等具有一定的相关性,现在对此作一综述.关键词:注意缺陷多动障碍;家庭环境;教养方式;依恋  相似文献

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.

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.  相似文献

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.  相似文献

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.  相似文献

The origins of innervation of the esophagus of the dog   总被引:2,自引:0,他引:2  
This study defined the origins of extrinsic efferent and afferent innervation of the normal canine esophagus. When all the layers of the wall of the 3 esophageal regions (cervical, thoracic and abdominal) were injected with horseradish peroxidase (HRP), labeled nerve cells were found in the nucleus ambiguus (NA) and parasympathetic nucleus of X (PX) of the brainstem. Most labeled cells in the NA were located in the compact column (retrofacial nucleus) while labeled cells in the PX were located in separate rostral and caudal areas. There was no somatotopic organization in either the NA or PX. Labeled sympathetic postganglionic neurons were found in the cranial cervical, middle cervical, cervicothoracic, thoracic sympathetic trunk and celiacomesenteric ganglia. The HRP injection of the esophageal wall labeled sensory cell bodies in the glossopharyngeal, proximal and distal vagal, and C2-T6 spinal ganglia. There was no discernible pattern of distribution of labeled cells in the autonomic or sensory ganglia. When the HRP injections were confined to the mucosa-submucosa layers of the thoracic esophagus, a small number of labeled cells were identified in the NA; however, no labeled cells were found in the NA when injections were confined to the mucosa-submucosa of either the cervical or abdominal esophageal regions. With these confined injections, the labeled nerve cells appeared in the rostral part of the PX. Thus, it appeared that the internal tunics of the esophagus (i.e., the mucosa and submucosa) were innervated by neurons in the rostral PX while the muscular tunic was innervated by neurons in the caudal PX and the rostral NA. After mucosa-submucosa injections, labeled sympathetic neurons appeared in the same ganglia that were identified after whole wall injections and these had a similar random distribution. These injections also labeled neurons in the glossopharyngeal, proximal vagal, and distal vagal ganglia, but unlike the whole wall injections there was no labeling in the spinal ganglia. This suggested that the labeled cells of the spinal ganglia seen after whole wall injections conveyed impulses from the tunica muscularis and serosa.  相似文献

Impact of our understanding of the genetic aetiology of epilepsy   总被引:2,自引:0,他引:2  
A genetic contribution to aetiology is estimated to be present in up to 40% of patients with epilepsy. It is useful to categorise genetic epilepsies according to the mechanisms of inheritance into Mendelian disorders, non-mendelian or ‘complex’ disorders, and chromosomal disorders. Over 200 Mendelian diseases include epilepsy as part of the phenotype, and the genes for a number of these have been identified recently. These include autosomal recessive progressive myoclonic epilepsies such as Unverricht-Lundborg disease, Lafora disease and the neuronal ceroid lipofuscinoses, and three autosomal dominant idiopathic epilepsies. The last named have been shown to arise from mutations in ion channel genes. Autosomal dominant nocturnal frontal lobe epilepsy is caused by mutations in CHRNA4, benign familial neonatal convulsions by mutations in KCNQ2 and KCNQ3, and generalised epilepsy with febrile seizures plus by mutations in SCN1B. ‘Complex’, familial epilepsies are more difficult to analyse, but evidence has been obtained for loci predisposing to juvenile myoclonic epilepsy on chromosome 6p and 15q. Lastly, the genes underlying several spike-wave epilepsies in mice have been cloned, and three of these encode sub-units of voltage-gated calcium channels.
