    Diagnostic capacity and preliminary evaluation of Clock drawing Test, to order criteria from Cacho's version, for patients with mild Alzheimer's disease in Chilean population [Capacidad diagnóstica y validación preliminar del test del reloj, versión de cacho a la orden, para enfermedad de Alzheimer de grado leve en población chilena]

    Background: To perform a study with discriminant power and validity using the Clock drawing Test by instruction (CDTI) in patients with mild Alzheimer's disease (MAD). Materials and Methods: Phase I diagnostic test study. We included a healthy control arm of 58 elderly people and 40 cases with mild Alzheimer's disease. All participants were examined and diagnosed by clinical consensus. The MMSE, CDTI and clinical record were obtained. Results: There were significant differences between the study groups regarding cognitive tests' performance when comparing age and education, but no differences were found when comparing gender. ANCOVA test showed no significant effect exerted by the demographic variables on cognitive performance in any group. The sensitivity (CTO=84[%] vs MMSE=79, 3[%]), specificity (92, 5[%] vs 82, 5[%]) and diagnostic utility of the CDTO were higher than one's resulting form the MMSE (=0, 90, p=0, 000). The combined use of both instruments increased diagnostic capacity. The best cutoff point for the diagnosis of mild dementia was ≤ 6 points in CDTO and ≤ 23 in MMSE. Both instruments correlated statistically. Conclusions: The CTO is a useful test and can discriminate between cognitively healthy subjects and patients with EAL when appliying the "to order" criteria from Cacho's version.

    Effects of a combined program of physical activity and cognitive training in Chilean patients with mild Alzheimer [Efectos de un programa combinado de actividad física y entrenamiento cognitivo en pacientes chilenos con Alzheimer leve]
    (Ediciones Doyma, S.L., 2015) López, Norman; Véliz, Alex; Soto Añari, Marcio Fernando; Ollari, Juan; Chesta, Sergio; Allegri, Ricardo
    The combined use of cognitive activity (CA) and physical activity (PA) seems to modulate the factors associated to the incidence of mild Alzheimer. Objectives To examine the effects of a combined intervention of CA and PA on cognitive performance in the elderly with mild AD. Method Quasi-experimental design, single blind evaluation with groups comparison. Participants 80 subjects = 60 years with neurological diagnosis of mild Alzheimer's dementia, of whom 60 completed the study (19 men and 41 women). Participants were randomly divided into an intervention group (IG: n = 24, M = 71.8 years, SD = 5.5) subjected to a combined program of cognitive training and physical activity for 6 months, and a control group (CG: n = 36, M = 73.8 years, SD = 6.3) composed of sedentary subjects who didn't do any physical activity or were subjected to cognitive training during the study. Results inter and intragroup t-student tests reported significant differences in MMSE, TRCF, TAAVR and TMT-A and B for the GI, an increase in the mean performance of all dimensions evaluated after AF program and BC, in the CG. The ANCOVA reported favorable evidence of the impact of AC and AF on cognitive function of GI versus controls (f = 17,378, P<.000). Conclusions favorable results showing a significant difference in the study groups, emerging as the CA and PA improves cognitive performance of the elderly with dementia were found. © 2014 Sociedad Neurológica Argentina.
