At the Erb's point and spinal cervical level, we distinguished the classically described potentials (N9, N13, N14) and the cortical \"far-field\" potentials such as: P17, N20, P24, N35 and sometimes P45. The central conduction time was calculated by determination of the interpeak latency N9-N13 and N13-N20 (for the upper limb) and LP-P37 for the lower one. A study of 100 patients with peripheral nerve diseases: 30 polyneuropathies, 50 radiculopathies, 9 cases with carpal tunnel syndrome, 5 with brachial plexus injury, 6 with compressive or traumatic diseases of the peripheral nerves, demonstrates the value of the SEPs in the assessment of the nervous lesion site (central or peripheral). In polyneuropathies, a decrease in amplitude and delayed latency of the N9 potential as well as delayed latency of the early cortical potentials on stimulation of the median and tibial nerves occurred. Delayed N9 and low amplitude with delayed latency spinal potential (N13 and LP) were found in radiculopathies. In myelopathies, the central spinal conduction time (N9-N13) was delayed and there were also delayed latencies of the cortical SEPs on lower limb stimulation. The patients with brachial plexus injury had a change in the N9 to N13 amplitude ratio, with prognostic value. Cortical recordings of the SEPs are also of special prognostic value and may suggest the surgical exploration when the axonal functional continuity is lost in brachial plexus injury and compressive or traumatic lesions of the peripheral nerves.","PeriodicalId":76209,"journal":{"name":"Neurologie et psychiatrie","volume":"27 2","pages":"111-25"},"PeriodicalIF":0.0,"publicationDate":"1989-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13695536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The importance of cerebral lesions of vascular origin in the morphopathologic picture of old age dementia.","authors":"M Alexianu, B Tudorache, M Podani","doi":"","DOIUrl":"","url":null,"abstract":"Our study refers to the complex neuropathologic examination of 70 demented patients (40 males and 30 females) above 60 years of age. Proportion of different types of cerebral damage with vascular pathogeny showed that 78% of the vascular dementia cases had as morphological background various aspects of multi-infarct dementia; softenings of variable size and lacunae, associated or not with myelinic rarefactions and pallor specific to subcortical arteriosclerotic encephalopathy; the remaining cases pointed to single anoxic lesion and/or subcortical encephalopathy. Perfect clinico-morphological diagnostic concordance has not always been reached in our sample--as in literature cases--often due to the dementia subtypes overlapping, and to the fact that the same clinical syndrome may show in different cerebral lesions. Likewise, no correlation has been found between lesion type, site or size and clinical picture or dementia course, which was also reported by other authors. On a morphopathogenic basis, we support the view that necrotic lesions of ischemic origin--multi-infarct and lacunar dementias--should be distinguished from myelinic rarefactions and pallor in the white matter, whose pathogeny is still controversial. Due attention is paid to the importance of the venous factor in the development of subcortical encephalopathy.","PeriodicalId":76209,"journal":{"name":"Neurologie et psychiatrie","volume":"27 2","pages":"133-45"},"PeriodicalIF":0.0,"publicationDate":"1989-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13918880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
