ABSTRACT
INTRODUCTION: Mild traumatic brain injury (mTBI) has traditionally been considered to cause no significant brain damage since symptoms spontaneously remit after a few days. However, this idea is facing increasing scrutiny. The purpose of this study is to demonstrate the presence of early cognitive alterations in a series of patients with mTBI and to link these findings to different markers of brain damage. METHODS: We conducted a prospective study of a consecutive series of patients with mTBI who were evaluated over a 12-month period. Forty-one (3.7%) of the 1144 included patients had experienced a concussion. Patients underwent a routine clinical evaluation and a brain computed tomography (CT) scan, and were also administered a standardised test for post-concussion symptoms within the first 24hours of mTBI and also 1 to 2 weeks later. The second assessment also included a neuropsychological test battery. The results of these studies were compared to those of a control group of 28 healthy volunteers with similar characteristics. Twenty patients underwent an MRI scan. RESULTS: Verbal memory and learning were the cognitive functions most affected by mTBI. Seven out of the 20 patients with normal CT findings displayed structural alterations on MR images, which were compatible with diffuse axonal injury in 2 cases. CONCLUSIONS: Results from this pilot study suggest that early cognitive alterations and structural brain lesions affect a considerable percentage of patients with post-concussion syndrome following mTBI.

Se describe una experiencia clínico-formativa en el ámbito hospitalario, donde destacan los aportes de la neuropsicología en la atención multidisciplinaria a pacientes con tumores cerebrales. Se ejemplifican cuatro casos atendidos en el Servicio de Neurocirugía del Hospital México en Costa Rica, a quienes se les realizó una valoración neuropsicológica como parte del protocolo de atención en cirugía de resección tumoral. Se documenta una leve pero consistente tendencia a la mejoría en los rendimientos tras la intervención neuroquirúrgica de los casos reportados, evidenciando, también, las secuelas neurocognitivas y emocionales que permanecen e impactan directamente la calidad de vida. Se discute sobre los retos asociados a la expectativa sanitaria de prolongación de la vida pero preservando su calidad y funcionalidad.
The systematization of a clinical and educational experience in a hospital setting shows evidence of the neuropsychological contributions to the multidisciplinary care for patients with brain tumors. Four cases of people diagnosed with brain tumors are exemplified. The patients were treated at the Neurosurgical Unit at the Hospital Mexico, Costa Rica. Each patient underwent neuropsychological evaluations as part of the established protocol for neurosurgical interventions. Results showed a slight yet consistent trend of cognitive performance improvement after each surgery, and identified residual neurocognitive consequences that would have a direct impact on the patients quality of life. This paper discusses the challenges associated with health expectancy of prolonging life while preserving its quality and functionality.
