Less than 30 ml blood per 100 grams of brain tissue per minute results in syncope. The critical threshold of cerebral hypoperfusion at which syncope ensues is 50% below baseline mean cerebral \u0000flow velocity. \u0000OBJECTIVE: \u0000The aim of the study was to determine the EEG abnormalities in the intervals of Breath-Holding Spells in children from 6 months to 5yrs. \u0000METHODS: \u0000An observational prospective study was done at Institute of Child Health and Hospital for Children between May 2016 and October 2016, on children diagnosed as having Breath Holding Spells by clinical history and laboratory evaluation, including complete blood count (CBC), ECG, Echocardiography and Electroencephalography (EEG). \u0000RESULTS: \u0000A total of 100 children (63 boys, 37 girls) with breath holding spells comprised the study group compared with similar age and sex group of 100 children with simple febrile convulsions served as controls. We found that mean age of onset was 12.7 months. Cyanotic spells (62%) were predominated over pallid spells (26%). There were positive family history (26%) and consanguinity (13%) in the study patients. Mean haemoglobin values was significantly lower in \u0000children with BHS (9.978±0.925 g/dl) than with controls (10.276±0.947). Electroencephalographic study in children with BHS showed no significant abnormality except for one child which had slow wave. \u0000CONCLUSION: \u0000Electroencephalographic study in combination with detailed history and clinical observation is of value in differentiating breath holding spells from convulsive disorders. Routine referral of children with clinical diagnosis of breath holding spells to paediatric neurology clinics is unnecessary and routine EEG is not appropriate investigation in the initial evaluation of breath \u0000holding spells.","PeriodicalId":14163,"journal":{"name":"International journal of neurology","volume":"84 1","pages":"95-107"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72678261","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}

Dushanova, Mario Christov","doi":"10.17554/J.ISSN.2313-5611.2017.03.62","DOIUrl":"https://doi.org/10.17554/J.ISSN.2313-5611.2017.03.62","url":null,"abstract":"Cognitive decline and symptoms of attention deficits, executive dysfunction, and memory impairments describe dementia in the elderly. This review focuses on particular frequency oscillations that occur within the affected brain regions which could be used to classify some idiopathic dementias as specific diseases and could contribute additional information to the clinical data in evaluating age changes that are of benefit for a treatment of cognitive alterations. The main question, whether the changes of event-related potentials (ERPs) and frequency band responses (ERBRs) for sensory stimuli are related to plasticity in neural recruitment during stabilization of sensory/cognitive mechanisms accompanying aging or are underlying pathological changes, remains unknown. We review the effect of aging on low (δ, θ, α) and high (β1, β2, γ1, γ2) ERBRs in an auditory discrimination sensorimotor tasks (low–frequency – right hand movement, high–frequency tone – left movement) at frontal, central, parietal and occipital cortical locations at short latency (post–stimulus interval 0–250 ms; putative sensory processing period) and long latency (250–600 ms; putative cognitive period). High tone stimulation and movement requirements lead to a delay of ERP components in elderly subjects and their amplitudes diminish with increasing age. The amplitudes of β2, γ, and low-frequency activity are more pronounced with progressive age, but the β1 component is less affected by age during the sensory processing. The age difference with respect to scalp distribution is tone-independent for δ/θ, but not for α-activity. Age- and tone-dependent α-changes are focused on frontal and sensorimotor areas. The low- and high-frequency amplitudes during the cognitive processing diminish with increasing age, except for the frontal β2 and γ high tone responses, while the β1 activity is more widespread than in the shorter latency period. This age difference increases in fronto–parietal direction more expressed after high tone stimulation. The age influences more the cognitive processes than the sensory ones.","PeriodicalId":14163,"journal":{"name":"International journal of neurology","volume":"16 1","pages":"327-334"},"PeriodicalIF":0.0,"publicationDate":"2017-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78253434","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}
