Background
Spinocerebellar ataxia type 10 (SCA10) is an autosomal dominant cerebellar ataxia, characterized by epilepsy, ataxic symptoms, and cognitive impairments linked to Cerebellar Cognitive Affective Syndrome (CCAS). The Cerebellar Cognitive Affective Syndrome Scale (CCAS-S) has been developed to identify CCAS across various cerebellar patholo...
COVID-19 is a disease known for its neurological involvement. SARS-CoV-2 infection triggers neuroinflammation, which could significantly contribute to the development of long-term neurological symptoms and structural alterations in the gray matter. However, the existence of a consistent pattern of cerebral atrophy remains uncertain.
Our study aimed...
Investigating the role of host genetic factors in COVID-19 severity and susceptibility can inform our understanding of the underlying biological mechanisms that influence adverse outcomes and drug development. Here we present a second updated genome-wide association study (GWAS) on COVID-19 severity and infection susceptibility to SARS-CoV-2 from t...
Background:
Recent resting-state functional magnetic resonance imaging studies have reported abnormal functional connectivity (FC) in the prefrontal cortex (PFC)-striatum circuit in patients with premanifest Huntington's disease (HD). However, there is a lack of evidence showing persistence of abnormal frontostriatal FC and its relation to cogniti...
Spinocerebellar ataxia type 10 (SCA10) is an autosomal dominant disorder caused by an expanded pentanucleotide repeat in the ATXN10 gene. This repeat expansion, when fully penetrant, has a size of 850 to 4500 repeats. It has been shown that the repeat composition can be a modifier of disease, e.g., seizures.

El Laboratorio de Psicobiología de la Facultad de Psicología-Xalapa de la Universidad Veracruzana se creó en 2003, por iniciativa del doctor Víctor Manuel Alcaraz Romero, con la finalidad de desarrollar investigaciones en el área de las neurociencias dirigidas a explicar las bases biológicas del comportamiento y sus alteraciones en diferentes etapa...
Este libro se dirige a estudiantes y profesionistas en salud y educación quienes, en la práctica diaria, enfrentan problemáticas en las que se requiere su acción para modificar el comportamiento humano desde las más tempranas etapas del desarrollo del niño, hasta el adulto mayor. El conjunto de estas investigaciones destaca la importancia de la mul...

En el ámbito hispánico son pocos los estudios que se han interesado en el análisis de las alteraciones morfológicas en la afasia, y la mayoría de ellos se han centrado en la morfología flexiva (Ardila, 1992; López-Villaseñor y Calvo, 2013; Guillén, 2018). En este escenario, los procesos derivativos y, aún más, el análisis de las palabras compuestas...
La adquisición de los procesos cognoscitivos en los primeros años de vida muestra una relación estrecha con el desarrollo de habilidades motoras. En la etapa preescolar, el desarrollo de conceptos y las nociones de aprendizajes escolares como la lecto-escritura permiten conocer los procesos cognoscitivos de los niños. Se realizó una investigación d...
Abstract
Neuropsychological assessments allow characterizing the presence of cognoscitive and behavioral changes. Difficulties answering neuropsychological tests can affect the academic performance of university students. The objective es the present study was to analyze the relationship between the results of a neuropsychological assessment and th...
Intellectual disability consists of alterations in the functionality of basic psychological processes as a result of dysfunctions in the nervous system. They can be assessed through neuropsychological evaluations. The neuropsychological diagnosis must be supported by results of psychometric tests and behavioral observations. Case studies allow to e...
The acquisition of cognitive processes in the first years of life shows a close relationship with the development of motor skills. In the preschool stage, the development of concepts and the notions of school learning such as reading-writing allow to know the cognitive processes of children. A descriptive, observational, cross-sectional research wa...
