ABSTRACT

Background Several instruments are available to measure cognitive functioning in older adults. However, there is paucity of information about their factorial structure and psychometric properties. Aim To determine the factorial structure and the internal reliability of the Mini Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA) and the Adenbrookke´s Cognitive Examination (ACE-R), and their cognitive impairment detection capabilities. Material and Methods MMSE, MoCA and ACE-R were applied to 203 older adults aged 54 to 88 years (77% women), excluding participants with dementia. Results The factorial structure of the MMSE suggested that items referred to memory process should be eliminated due to their low reliability and factor loading (b = 0.12; p = 0.146). Although the MoCA had a good reliability, object denomination process items also had to be dropped (b = 0.22; p = 0.003). The ACE-R demonstrated a single factorial structure for all cognitive processes and had a good internal consistency. MMSE, MoCA and ACE-R classified as having dementia 5, 27 and 42% of participants, respectively. Conclusions MoCA and the ACE-R scales appear as better instruments to detect dementia in older people.

ABSTRACT

Este artículo presenta una breve reseña sobre el Deterioro cognitivo leve en adultos mayores, considerando los principales precursores que anuncian, y los factores de riesgo que aceleran los procesos de envejecimiento cognitivo, los cuales aumentan la probabilidad de recibir un diagnóstico de DCL. A su vez, la presencia de DCL aumenta el riesgo y eventual tránsito hacia la demencia, especialmente la demencia de tipo Alzheimer por otra parte, en el artículo se describen las diferentes modalidades de presentación del deterioro cognitivo, revisando también el DCL asociado a la sintomatología depresiva, a la enfermedad de Parkinson y otras enfermedades degenerativas del SNC. La presente revisión, permite dar cuenta de hallazgos recientes y relevantes con relación a la disfunción cognitiva en adultos mayores, quienes representan una proporción cada vez mayor de la población nacional y mundial.


This article presents a brief overview of mild cognitive impairment in older adults, considering its main anticipating precursors, and the risk factors that may accelerate the processes of cognitive aging, which increases the likelihood of being diagnosed with MCI. In turn, the presence of MCL increases the risk and eventual transition to dementia, particularly Alzheimer’s dementia. Moreover, the article describes the different forms cognitive impairment may present itself, and also reviews MCI associated with depressive symptoms, Parkinson’s disease and other degenerative diseases of the CNS. This revision accounts for recent and relevant findings regarding cognitive dysfunction in the elderly, who represent a growing share of national and global populations.

ABSTRACT

La distonía resulta de una co-contracción sostenida de músculos agonistas y antagonistas que puede causar torsión, movimientos involuntarios o posturas anormales que interfieren con el control voluntario de la mano, u otro grupo muscular, involucrados en una determinada acción; por ejemplo, tocar un instrumento, o escribir.El presente estudio descriptivo, de caso único, buscó probar la efectividad de un tratamiento que combinó tres técnicas (técnica del umbral, imaginería, y relajación por neurofeedback) en el reentrenamiento de un concertista profesional con distonía focal. Según evaluación por jueces, los resultados después de dos semanas de tratamiento, no fueron concluyentes. Sin embargo, el reporte experiencial del propio músico dio cuenta de una clara mejoría. Ante la carencia de un método efectivo para larehabilitación demúsicos con distonía focal, la relevancia del presente estudio consistió en identificar y combinar técnicas específicas que pueden contribuir a ese propósito. En estudios futuros, sería de interés probar el efecto del mismo tratamiento,pero más prolongado; o el efecto de la incorporación de las técnicas en sucesión progresiva, iniciando siempre con la relajación por neurofeedback.


Focal dystonia results from a sustained simultaneous co-contraction of agonists and antagonists muscle fibers which can cause twisting, involuntary movements or abnormal postures that interfere with voluntary control of the hand, arm, mouth, or other muscle groups involved in a given action; for example, playing an instrument, or hand writing. This descriptive, single case study, sought to explore the effectiveness of a treatment that combined three procedures: the threshold technique, imagery, and neurofeedback induced relaxation, in retraining of a professional cello player with focal dystonia. After two weeks of treatment, experts judged the results inconclusive; however, the report from the actual patient accounted for a note worthy recovery over time. In the absence of an effective method to rehabilitate musicians with focal dystonia, the relevance of this study resided on thepossibility of identifying and combining specific techniques that could be effective. Future studies might want to explore these same or different techniques, but perhaps for a longer period of time.
