NCT02944032

Brief Summary

The main objective of the study is to assess the efficacy of a home-based, computerized cognitive training (CT) program, called CogmedRM, targeted to improve working memory in children with NF1 and working memory difficulties. This is a Phase II randomized parallel group controlled clinical trial comparing two interventions on cognitive outcomes. Participants will be stratified by stimulant medication use and randomized equally between the two interventions within stratum. Participants will be in the study for to 11 weeks.

Study Arms (2)

Cogmed

EXPERIMENTAL

Cogmed RM is a computer program that consists of twelve visually-engaging and interesting exercises that target skills involving visuo-spatial and verbal Working Memory. During the intervention, children complete 25 training sessions. Children are asked to complete between 3 and 5 sessions per week, so the total treatment time to complete 25 sessions may range from 5 to 9 weeks. For children completing CogmedRM, sessions typically last between 25 and 45 minutes, depending on the child's working memory span.

Other: CogmedRM

MobyMax

ACTIVE COMPARATOR

MobyMax's "Reading Stories" program is a program that focuses on reading comprehension skills. Participants will start their training with stories that are matched to their reading "grade" level. Each grade contains 30 lessons, with 3 stories in each lesson. Participants are given questions to answer at the conclusion of each story, and children advance or remain at that level depending on the progression of their reading skill. Participants randomized to this program will be asked to train 30-45 minutes per session for 25 training sessions over a 5 to 9 week period.

Interventions

Cogmed RM is a computer program that consists of twelve visually-engaging and interesting exercises that target skills involving visuo-spatial and verbal Working Memory. Difficulty of the tasks is automatically adjusted on a trial-by-trial basis throughout each training session to match a child's current working memory span, such that as the child becomes more proficient, the exercises become more difficult. During the intervention, children complete 25 training sessions. Children are asked to complete between 3 and 5 sessions per week, so the total treatment time to complete 25 sessions may range from 5 to 9 weeks. For children completing CogmedRM, sessions typically last between 25 and 45 minutes, depending on the child's working memory span.

Eligibility Criteria

Age8 Years - 16 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • years old at time of screening
  • NF1 Diagnosis based on National Institute of Health (NIH) criteria
  • Has an identified caregiver who is willing and able to oversee the training practice during the intervention period
  • Has access to a telephone and phone number where they can be reached
  • Both patient and caregiver have reading, speaking, and listening comprehension of English
  • Treated with a stable dose of stimulant medication for at least the last 30 days and not planning to change the dose during study participation or receiving no stimulant medications for at least the last 30 days and not planning to initiate a trial of stimulant medications for the duration of the study.
  • \>1 Standard Deviation (SD) below the mean on the WISC-V-Integrated Spatial Span Backwards task or a Spatial Span Backwards score \>1 SD below the participant's estimated IQ.

You may not qualify if:

  • Full scale IQ\<70, as estimated by WASI-II (Block Design, Vocabulary, Matrix Reasoning, Similarities).
  • Note: In cases where there is a statistically significant difference between verbal IQ and performance IQ (.05 level as determined by the WASI-II manual), participants will be eligible if at least one of these quotients is 70 or above
  • Current treatment for intracranial lesions, progressive tumors as per MRI evaluation or treatment with chemotherapy within the past 6 months
  • A motor, visual, or auditory handicap that prevents computer use
