ACALCULIA CARACTERISTICAS PDF

Performance of a Brazilian population in the EC calculation and number processing battery: A pilot study. A simple arithmetic operation demands many neurocognitive mechanisms that involve verbal, spatial and graphical processing, memory and attention. RESULTS: The educational level was significantly linked to performance in the majority of tests of the EC battery, whereas no differences were noted regarding age and gender. Key words: mathematics, population characteristics, calculation ability, numerical knowledge, acalculia.

A review of current criteria for the diagnosis of categories related with vascular cognitive impairment, in particular the nomenclature, diagnostic criteria, and differential clinical-radiological findings.. The criteria for the diagnosis of vascular cognitive impairment have evolved, but available criteria were designed basically for differentiating between vascular dementia and dementia due to Alzheimer disease, and for research purposes.

Nevertheless, in clinical practice precise elements are required for: 1 Clinical diagnosis of dementia and mild cognitive impairment; 2 Clinical and neuroimaging criteria for identification of the various cerebrovascular lesions associated with cognitive dysfunction, and 3 A formulation of the aetiogenic-pathogenic relationship between cognitive impairment and cerebrovascular lesions.

For this reason, a review was carried out on the diagnostic elements of vascular cognitive impairment categories, classification, and their most relevant characteristics. It highlights the characteristic for the diagnosis of multi-infarction dementia, strategic single infarct dementia, small vessel disease with dementia, mixed dementia, and vascular mild cognitive impairment..

Standardisation is required, by a multidisciplinary expert team, as regards nomenclature and criteria for the diagnosis of the full spectrum associated with vascular cognitive impairment and especially for vascular dementia and its categories..
