Cognitive Rehabilitation for People With Multiple Sclerosis

Study Overview
=================
Brief Summary
-----------------
Cognitive rehabilitation is designed to enhance a person's capacity to process and interpret information and improve their ability to function in all aspects daily, family and community life. Given the clear and consistent documentation of cognitive deficits in persons with MS, the most notable deficit being information processing speed, learning and memory and executive function, there is an obvious need for effective cognitive rehabilitation. The proposed study will be a randomized controlled single-blinded trial with treatment and wait-list control group. The treatment group will be administered the Goal Management Training (GMT) program; the wait-list control group will be given usual care by their neurologist. Intervention details: The treatment group will receive in-person computerized cognitive rehabilitation (using the GMT program) (virtual training is optional) for 5 weeks (40-min sessions, twice per week), session will be tailored according to patient cognitive concerns at index assessment, and level of ability. The wait list control group, will not receive treatment Our primary outcome is information processing speed, secondary aims include learning and memory, and executive function. The minimal assessment of cognitive function in MS (MACFIMS) will be utilized to assess cognitive function. Additionally, tertiary aims include the following patient reported outcomes (PROs) will be collected: the hospital anxiety and depression scale (HADS), the modified fatigue impact scale (MFIS), the multiple sclerosis impact scale (MSIS-29), and the European quality of life (EQ-5D-5L) scale, to capture level of depression and anxiety, fatigue, impact of MS and quality of life. Cognitive performance of all patients in both groups will be assessed at baseline, immediate post-5-week assessment, and at post 6-month follow-up assessment. We hypothesized that, compared to persons in the wait-list group, the participants receiving the GMT intervention will demonstrate significant improvements across all cognitive measures. The wait-list control group will be given the option to receive the GMT intervention after the 6 months follow-up is complete. The individuals in the treatment group, wishing to continue with the GMT program, will be given a referral by Dr. Feinstein to a GMT certified therapist.

Detailed Description
-----------------
Background: Multiple sclerosis (MS) is a chronic disabling disease of the central nervous system, with symptom onset commonly occurring between the ages of 20 to 40 years old; with females being at a higher risk of developing MS than men. Cognitive impairment (CI) in the last decade has been acknowledged as a prevalent core feature of the MS clinical picture, along with mobility issues. Cognitive impairment affects up to 44.5 % of people with relapsing remitting MS (RRMS), 79.4 % in secondary progressive MS (SP), and up to 91.3 % in people with primary progressive MS. The most prominent deficits reported being information processing speed, learning and memory and executive function. Cognitive decline has been found to directly affect the quality of life of people with MS, impacting participation in social activities, driving abilities, employment productivity, and task of daily living. Currently there is no approved medication for the treatment of CI in MS, patients and their clinicians are left with basically symptomatic treatments. In the last decade there has been an increase in developing non-pharmacological rehabilitation treatment to reverse or to at least slow down the progression of cognitive decline with cognitive rehabilitation. KEYWORDS Learning and memory; executive function; information processing speed; Goal Management Training; multiple sclerosis. Proposal and aims: Cognitive rehabilitation (CR) is designed to enhance a person's capacity to process and interpret information and improve their ability to function in all aspects of family and community life. Given the clear and consistent documentation of cognitive deficits in persons with MS, there is an obvious need for effective cognitive rehabilitation. A leading cognitive rehabilitation program called Goal Management Training® (GMT), has been used as an effective treatment for a variety of patient populations, including traumatic brain injury, stroke, schizophrenia, attention deficit hyperactivity disorder and multiple sclerosis for the treatment of cognitive deficits specifically executive function, learning & memory, and information processing speed. A doctoral dissertation completed by Nadine Richards (2013), under the supervision of Brian Levine, investigated the effectiveness of the GMT intervention for multiple sclerosis (MS) patients with impaired cognition; using a double-blinded randomized controlled trial, with treatment group employing the GMT intervention and the sham group employing a psycho-educational intervention. Twenty eight participants were recruited, and randomized; participants in the GMT intervention learned stepwise strategies (Stop-State-Split) to keep track of their daily activities, which included mindfulness training to enhance attentional awareness and control. The results post-training, revealed that compared to the psycho-educational control group, the GMT group was associated with greater improvement on test of executive-attentional processes as well as functional task performance and observable cognitive functioning in daily life activities, with effects remaining visible at 6 months. As of date this remains the only study carried out on patients with MS using the GMT intervention. To elaborate further the GMT program, is a standardized metacognitive rehabilitation program designed to improve cognition. The GMT program contains 20 hours of training, that include employing the following tools psychoeducation, narrative examples mindfulness practice, and assignments completed both between and within sessions. The main objectives of the GMT intervention is to train individuals to periodically STOP what they are doing, attend to task goals, evaluate their performance, and monitor or check their performance as they proceed. The current version of GMT as mentioned above consists of 20 hours of training and its material and manual were made commercially available in 2012 by Baycrest Hospital (https://gmt.learnworlds.com/). The GMT cognitive rehabilitation training program is not considered a medical device and therefore not subject to Health Canada certification for use. As of April 20, 2023, the Goal Management program is now widely available through TELUS health's AbilitiCBT platform, and for clients across Canada and the United States (TELUS Health, 2023). Given the devastating effects of cognitive impairment on social functioning, occupational functioning and everyday life activities in people with MS (pwMS), the amelioration of cognitive deficits is likely to improve everyday functioning in pwMS, thus greatly reducing the impact of the disease on the lives of people with MS and the overall cost of the disease to society at large. Therefore, efforts to improve cognitive abilities in this population may result in significant improvements in overall quality of life (QOL). The currently proposed study seeks to do just that. The proposed pilot study will be a randomized controlled single-blinded trial with treatment and wait list control group. We aim to assess information processing speed, learning and memory, and executive function. The minimal assessment of cognitive function in MS (MACFIMS) will be utilized, to assess cognitive function. Additionally, the following PROs will be collected: the hospital anxiety and depression scale (HADS), the modified fatigue impact scale (MFIS), the multiple sclerosis impact scale (MSIS-29), and the European quality of life - 5 dimension - 5 level (EQ-5D-5L) scale, in order to capture level of, depression and anxiety, fatigue, impact of MS and quality of life. Patients in the cognitive rehabilitation group will be treated by GMT for 5 weeks (2 hour sessions, twice per week). The wait list control group will be given usual care/ routine care which consist of being provided with a list of cognitive compensatory strategies to do on their own. Cognitive performance of all patients in both groups will be assessed at baseline, immediate post-5-week assessment, and at post 6 month follow-up assessment. We hypothesized that, compared to persons in the wait-list control group, the participants receiving the Goal Management Training would demonstrate significant improvements across all cognitive measures.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of participants with improved Information processing speed | The Symbol Digit Modality Test (SDMT), will be use to measure changes in processing speed. A poor SDMT score tells us that cognitive decline occurred. Scoring involves summing the number of correct substitutions within the 90 second interval (max = 110). Higher scores means a better outcome. | 5 weeks immediate post assessment, and 6 months post assessment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of participants with improved learning and memory | The California verbal learning test - 11 (CVLT-II) will be use to measure learning and memory. The CVLT-II is used to assess recall and recognition of items in a list of 16 nouns that belong to four categories (furniture, vehicles/ways of travelling, vegetables, and animals). the total raw score is the sum of correct responses on the five presentations. Higher scores means a better outcome. | 5 weeks immediate post assessment, and 6 months post assessment | 
| Number of participants with improved executive function | The Brief visuospatial memory test - revised (BVMT-R) will be use to measure executive function. Recall performance is recorded for each of the immediate recall trials (Trial 1, Trail 2, and Trial 3) and for the delayed recall trial (Delayed Recall).The recall scores are combined to form three additional summary measures of executive memory. Higher scores means a better outcome. | 5 weeks immediate post assessment, and 6 months post assessment |
