Brief summary
This pilot study will document the efficacy of a behavioral intervention for Processing Speed (PS) in Multiple Sclerosis (MS), Speed of Processing Training (SPT), which has been successful used in the aging population in several studies. This study will (1) apply a treatment protocol for PS impairments, well-validated in aging, to persons with MS with impaired PS, and document its efficacy on standard neuropsychological (NP) tests (2) assess the effectiveness of the intervention utilizing global measures of daily life, including an objective measure (TIADL) (3) examine the long term impact of SPT. This study is unique in that it will be the first to evaluate the efficacy of a highly-manualized structured behavioral treatment for processing speed deficits in persons with MS utilizing the optimal methodology for carrying out such studies, a randomized clinical trial. Given the prevalence of PS deficits in the MS population and the significant impact such deficits have on everyday functioning, public safety, and overall quality of life, the identification of an effective intervention for PS deficits in MS could have a profound impact on the population and society as a whole.
Interventions
BEHAVIORALSpeed of Processing Training
SPT involves trainer-guided practice of computer-based exercises, including Target Detection (indicating presence or absence of targets, identifying targets, etc.) and Discrimination and Localization (performing same/ different discriminations of targets presented very quickly and followed by a masking pattern) 10, 19, 84. Display speed, ranging from 17 to 500 ms, is the primary manipulation during training, which increases task demands and thus demands on PS itself.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in scores on standardized tests of processing speed | Three points in time: Baseline (week 1), immediately following treatment (Group 1 - week 7, Group 2 - week 13), long-term follow-up (Group 1 - week 13, Group 2 - Week 19) | Standardized neuropsychological tests which be used will be used to determine whether there has been a change in speed of processing. |
