简要总结
The purpose of this initial study is to evaluate a new form of cognitive rehabilitation therapy for improving your ability to think, particularly how rapidly you process information that you receive from your senses, e.g., sight, hearing, and smell. The study will also test how often and how well you carry out tasks that rely on thinking in your daily life. You will be randomly assigned to receive the new therapy soon or about three months later. In other words, your treatment schedule will be determined by chance. The new therapy involves intensive, repetitive cognitive exercises (up to 3.5hr/day for 10 consecutive weekdays) with rest periods interspersed as needed.
详细描述
The purpose of this pilot study is to develop and test an intervention for slow processing of sensory input that not only increases the speed of processing but also produces improvement in how much and how well adults with this type of cognitive impairment carry out everyday tasks that rely on cognitive function. The intervention will combine Speed of Processing Training (SOPT) with a modified form of the Transfer Package (TP) from Constraint-Induced Movement therapy (CI therapy). SOPT has been shown to increase speed of processing in a variety of patient populations. The Transfer Package has been shown to produce transfer of gains from the treatment setting to everyday life when combined with training of arm use in the treatment in adults after stroke.
This early phase, randomized controlled trial (RCT) will have two arms: Immediate SOPT+TP (experimental group) and Delayed SOPT+TP (control group). The Immediate SOPT+TP group will receive the experimental intervention immediately after pre-treatment testing, and then be followed for a year. The Delayed SOPT+TP group will receive testing on the same schedule as the Immediate group up to 3-month follow-up. Delayed group participants will be permitted to receive care that is available in the community as part of typical clinical care during this period. After 3-month follow-up testing, Delayed group participants will receive the experimental intervention and then be followed up for a year. Thus, the study design is a RCT with a usual care control group featuring crossover to the experimental intervention for that group at 3 month follow-up.
In the experimental intervention, the length of each treatment session will vary from 2 to 3.5 hours per day, the number of treatment days per week will range from 2 to 5, and the number of weeks of treatment will range from 2 to 10. Accordingly, the interval between testing occasions may change depending on the findings from initial pilot work. Total hours of treatment will not exceed 35. Ranges are given rather than precise values because part of the purpose of this pilot work is to decide, on a preliminary basis, what is the best schedule of delivery. In addition, four follow-up telephone calls will be conducted each week for the first month after the end of treatment. Then, a follow-up telephone call will be placed once a month for up to 11 months. These telephone calls will permit elements of the Transfer Package to be delivered remotely, helping the patient to transition from taking part in treatment to living their daily lives. Each telephone call will last 30 to 60 minutes.
If a caregiver is available, the caregiver will be asked to complete interviews about the participant's progress (see below) and will be invited to support the participant in following the Transfer Package elements of the treatment (see below).
The outcomes that will be assessed are: speed of processing, performance of instrumental activities of daily living (IADL) that place demands on cognitive activity in the laboratory setting, and performance of IADL that place demands on cognitive activity outside the laboratory setting.

研究组 & 干预措施
Immediate Treatment
The treatment will have 3 components. The first component, Speed of Processing Training, is a computer game. Participants identify targets on the screen as rapidly as possible. The second component is training following shaping principles on simulated instrumental activities of daily living (IADL), such as making a telephone call or generating a shopping list, in the treatment setting. Shaping involves progressively increasingly the complexity of a task in incremental steps as a participant gains mastery. Frequent, positive feedback is another important aspect of shaping. The third component is a set of psychological techniques that will help participants apply the improvements from the game to carrying out tasks that rely on thinking in their daily

干预措施: Transfer Package from CI Therapy (Behavioral)
Delayed Treatment
Participants in this arm will receive testing on the same schedule as the Immediate Treatment up to six-month followup. Delayed Treatment participants will not receive any treatment from the study during this period but will permitted to receive any healthcare that is available on a clinical basis. After six-month followup, participants in this arm will be crossed over to receive the experimental treatment.

结局指标
主要结局
Canadian Occupation Performance Measure (COPM)
时间窗: Change from Day 0 to Day 17
The COPM is a widely used, transdiagnostic, individualized, structured interview that detects changes over time in a respondent's performance of five, self-selected activities of daily living (ADL). In this case, the instrument will be completed by a family caregiver and only assess instrumental ADL (IADL) with important cognitive components. Performance is rated using 10-point scale that ranges from 1-10 scale points. High scores reflect effective performance. The test score is the mean of the ratings of the five, self-selected IADL.
