Official title: Successful Aging and Enrichment (SAGE): Effects of Environmental Stimulation on Cognitive Health and Neuroplasticity

Status Active, not recruiting

Clinical Trial Summary

Progress has been made in understanding the impact of different kinds of structured intervention programs in improving cognitive processing and performance in older adults, and in determining whether there is electrophysiological evidence for neuroplasticity in individuals over the age of 65.

Clinical Trial Description

Study Procedures Pre-Intervention Assessment The initial screening evaluation will take place over two half-day sessions, each lasting 3 to 3.5 hours in a designated room in the Laboratory of Healthy Cognitive Aging, Center for Brain/Mind Medicine, Brigham and Women's Hospital (BWH), 221 Longwood Avenue, Boston, Massachusetts (MA). The sessions can be completed over one or two days, depending on the subject's preference. Pre-Intervention Assessment Session 1 The first session will include completion of informed consent, a medical history, demographic information, including socioeconomic status (SES), survey questionnaires, and tests of visual acuity. Screening Evaluation (for inclusion/exclusion) Cognitive Screen - The Mini-Mental State Examination (MMSE), a broad cognitive test on memory, spatial ability, memory and orientation, commonly used to screen for cognitive impairment - American National Adult Reading Test (AmNART), a test of word pronunciation that provides an estimated IQ - Logical Memory I and II, Wechsler Memory Scale-Third Edition, a test of verbal memory - Boston Naming Test (Short-form, 15-items), a test of confrontation naming. Depression Screen Geriatric Depression Scale Neurological/Physical Evaluation Subjects will undergo a structured neurological examination. Height and weight will be obtained to calculate BMI. Visual acuity will be measured (Snellen wall chart). Gait Gait will be assessed through a procedure in which subjects walk 10 meters under two conditions: 1. Single task (walking at a comfortable pace) 2. Dual task (walking at a comfortable pace while simultaneously counting backwards by 3's, beginning with a 3 digit number told to the subject) Every trial involving serial 3's will start from a different three digit number to reduce learning effects. Subjects will be given an opportunity to carry out an untimed practice trial. Under the dual task condition, subjects will be instructed to perform as well as possible on both tasks (i.e., no specified prioritization). Each condition will be done 2 times, with the order counterbalanced across subjects. The first and last meter (gait start up and slow down) will not be counted in the measurements. Time to walk 8 meters and number of steps taken will be measured. Under the dual task, investigators will also track how many numbers are generated while carrying out the serial 3's task (both correct and incorrect responses). In addition, the single task of counting backwards by 3's for 20 seconds will be tested twice in a seated position (once prior to and once after the gait testing). Informant Questionnaire Subjects will select someone who knows them well (family member or friend) to complete a set of questionnaires. One questionnaire will provide information about a person's level of functioning (based on the Clinical Dementia Rating Scale), and another will inquire about a person's level of engagement (Apathy Scale). e questionnaires will be enclosed with a letter explaining how to complete the forms. The investigators will provide a stamped, addressed envelope to return the questionnaires to us. A backup plan will be to mail these materials directly to the informant selected. This would occur if the materials were misplaced or if the subject requests us to do so. ;
