Studying lack of awareness of cognitive decline in neurodegenerative diseases requires measures of both anosognosia and denial.

The cause(s) of lack of awareness of cognitive decline in neurodegenerative diseases can be multifactorial. Yet neurologically oriented research on anosognosia of cognitive decline almost exclusively assumes that the underlying disturbance of neuro-networks that support various cognitive functions accounts for the reduced self-awareness. Cultural and psychosocial factors, including the person's emotional state, however, can contribute to the underreporting or avoidance of admitting to cognitive impairments in neurodegenerative diseases. Research on the causes of lack of awareness of cognitive decline in neurodegenerative disorders needs to include these variables. We briefly present two case examples of underreporting or "unawareness" of memory difficulties in persons with mild cognitive impairment (MCI) (or minor neurocognitive disorder). One presented with classic anosognosia for memory impairment, while the other initially reported no memory impairment but later admitted to "denying" her memory difficulties secondary to anxiety. Based on these patients' clinical presentations and available research, we suggest three potential screening items that may help identify probable denial of memory impairments when studying anosognosia in MCI.

From meaning to symptom reduction: contemporary approaches to psychotherapy after traumatic brain injury / Del sentido a la reducción de síntomas: enfoques contemporáneos de la psicoterapia después de un trauma cráneo encefálico

Introduction: During the last decades, psychological interventions have become central components of rehabilitation programs for Traumatic Brain Injury (TBI). Nevertheless, due to a wide variability of therapeutic approaches there is little agreement regarding which approach is more suitable, or whether key elements from different psychotherapies should be integrated. This article critically reviews several contemporary approaches that are dominant in the literature. Methods: In order to accomplish such goal, an all-time search on Web of Science and Google Scholar was carried, using TBI and Psychotherapy as key words (n = 72). Results: The main finding of this paper is that theoretical and technical variability among psychotherapies reflects differences in the 'level of care' that is targeted: symptom reduction, behavioral problem reduction, quality of life and meaning reconstruction. Four contemporary approaches to psychotherapy [cognitive behavioral, third wave cognitive behavioral, narrative and psychodynamic] are then briefly described, by presenting their main theoretical tenets, the level of care they target, and the existing evidence that supports their efficacy. Finally, the implications of using a 'levels of care' perspective when addressing the 'effectiveness' debate is considered, as well as the need to familiarize future clinicians with more integrative models of psychological support after TBI.

Introducción: Durante las últimas décadas, las intervenciones psicológicas se han convertido en un elemento central de los programas de rehabilitación para personas que han adquirido un Trauma Cráneo Encefálico (TEC). Este artículo revisa críticamente los enfoques contemporáneos predominantes en la literatura a la luz del concepto de "niveles de cuidado". Método: Se realizó una revisión bibliográfica entre los años 1985 y 2014 utilizando los motores de búsqueda Web of Science y Google Scholar, usando TEC y Psicoterapia como palabras claves. 72 artículos fueron seleecionados para revisión. Resultados: Existe una amplia variabilidad teórico/técnica en los enfoques utilizados en esta población, reflejando diferencias en los niveles de cuidado: reducción de síntomas, reducción de problemas conductuales, calidad de vida y reconstrucción de sentido vital. Cuatro enfoques psicoterapéuticos contemporáneos (cognitivo-conductual, cognitivo-conductual de tercera generación, narrativo y psicodinámico) son brevemente descritos, presentando sus supuestos teóricos, el nivel de cuidado que consideran como objetivo, y la evidencia existente que apoya su efectividad. Finalmente, se discuten las implicancias de utilizar una perspectiva de 'niveles de cuidado' en el debate sobre efectividad de la psicoterapia en personas con TEC, así como la necesidad de familiarizar futuros neuropsicólogos clínicos con modelos genéricos de apoyo psicológico para esta población.
