Eficacia de la rehabilitación cognitiva en un paciente con esclerosis múltiple progresiva primaria / Efficacy of cognitive rehabilitation in a patient with primary progressive multiple sclerosis

La esclerosis múltiple (EM) es una enfermedad inflamatoria crónica que cursa con la desmielinización y la neurodegeneración a nivel del sistema nervioso central. Existen tres tipos de EM en función de la progresión de la enfermedad, pero la mayor parte de los pacientes tienden a presentar déficits cognitivos. Por lo tanto, resulta imprescindible el desarrollo de programas de entrenamiento cognitivos dirigidos a la mejora de estos déficits y, en definitiva, a la mejora de la calidad de vida de estos pacientes. En este sentido, el objetivo principal de este estudio fue la puesta en marcha de un programa de entrenamiento cognitivo dirigido a un paciente con esclerosis múltiple progresiva primaria (EMPP) a lo largo de un año. Los resultados pusieron de manifiesto que algunos de los déficits cognitivos que presentó inicialmente el paciente mejoraron tras varios meses de intervención. En este sentido, el paciente presentó notables mejoras en el control inhibitorio y la flexibilidad cognitiva. No obstante, los déficits en la velocidad de procesamiento se mantuvieron constantes a lo largo de toda la intervención. Asimismo, aparecieron otros déficits a lo largo de la intervención que remitieron tras la adecuación de los objetivos de intervención. Por todo ello, nuestro estudio reforzó la importancia de la puesta en marcha de los programas de rehabilitación cognitiva dirigidos a pacientes con enfermedades desmielinizantes para paliar las secuelas cognitivas derivadas de las mismas. Además, es importante que estos programas de entrenamiento cognitivo sean revisados periódicamente para adecuar los objetivos del tratamiento.

Multiple sclerosis (MS) is a chronic inflammatory disease that involves demyelination and neurodegeneration at the level of the central nervous system. Despite the different characteristics of each of the three types of MS, most patients with this disease present significant cognitive deficits. Therefore, it is essential to develop cognitive training programs to improve these deficits and, ultimately, increase the quality of life of these patients. Thus, the main objective of this study was to implement a one-year cognitive training program with a patient with progressive primary multiple sclerosis (PPMS). The results showed that some of the cognitive deficits the patient initially presented improved after several months of intervention. In this regard, the patient presented noteworthy improvements in inhibitory control and cognitive flexibility. However, deficits in processing speed remained constant throughout the intervention. Likewise, other deficits appeared during the intervention that remitted after adapting the intervention objectives to the patient's needs. Therefore, our study reinforces the importance of implementing cognitive rehabilitation programs for patients with demyelinating diseases to alleviate the cognitive sequelae they produce. In addition, it is important to evaluate these cognitive training programs periodically in order to adapt the objectives and improve the patient's functionality.

The state of art of biological processes in paternal care / Processos biológicos na paternidade: estado de arte

This review of the state of art aimed to present the most recent data on neuronal, neurochemical, hormonal and genetic bases of paternal care using MEDLINE and PsycInfo databases (1970-2013). An integrated model of biological substrates that assist men in the transition to fatherhood is presented. Guided by a genetic background, hypothalamic-midbrain-limbic-paralimbic-cortical circuits were found to be activated in fathers when infant stimuli are presented. A set of specific neuropeptides and steroid hormones are produced and seem to be related to brain activation, potentiating the paternal phenotype. Together, genetic, brain and hormonal processes suggest the existence of biological bases of paternal care in humans, activated and enhanced by infant stimuli and responsive to variations in the father-infant relationship.

A presente revisão teve por objectivo apresentar o estado de arte dos dados mais recentes sobre as bases neuronais, neuroquímicas, hormonais e genéticas da paternidade, com recurso às bases de dados MEDLINE e PsycInfo (1970-2013). É apresentado um modelo de integração conceptual dos substratos biológicos que assistem os homens na transição para a parentalidade. Guiado por um background genético, circuitos neuronais hipotalámicos-mesencefálicos-límbicos-paralímbicos-corticais surgem ativados em pais quando lhes são apresentados estímulos infantís. Um conjunto de neuropéptidos e hormonas esteróides são também produzidos e relacionam-se com a activação neuronal, potenciando o fenótipo paternal. No seu conjunto, processos genéticos, neuronais e hormonais sugerem a existência de uma base biológica do comportamento paternal em humanos, activada e potenciada por estímulos infantís e responsiva a variações na relação pai-filho.
