Trial Outcomes & Findings for Trigeminal Nerve Stimulation for Attention Deficit Hyperactivity Disorder (ADHD) (NCT NCT01388530)

NCT ID: NCT01388530

Last Updated: 2016-04-11

Results Overview

A standard, frequently used, clinician completed measure of Diagnostic and Statistical Manual -IV (DSM-IV) ADHD symptoms. Scale ranges from 0 (best) to 54 (worst). Unit of Measure - units on a scale. Outcome value reflects change from baseline at endpoint (Week 8) in ADHD-RS.

Participant Flow

Recruitment was initiated in July 2011 and ended in October 2012. Participants self-identified or were referred from community providers in response to public advertisements.

Following informed permission/assent participants were assessed for eligibility and if meeting inclusion/exclusion criteria initiated 8 weeks of open-label Trigeminal Nerve Stimulation (TNS) treatment.

PRIMARY outcome

Timeframe: Baseline and Week 8.

Population: Participants with data at baseline and week 4. We included participants who participated in 4 weeks of treatment, but change comparison is baseline vs. week 8.

SECONDARY outcome

Timeframe: Week 8

Population: Participants with data at baseline and week 4. As with the ADHD-RS, we included participants with at least 4 weeks of treatment, but outcome was assessed at Visit 8 compared with baseline.

A global measure of clinical improvement compared with baseline. A standard clinical trials rating scale with value from 1 (very much improved) to 7 (very much worse). Unit of measure - percentage improved based on CGI-I scores of 1 and 2 versus all others.

SECONDARY outcome

Timeframe: Baseline and Week 8.

Population: Participants with data at baseline and week 4. We required 4 weeks treatment to include in analysis, but analysis is based on comparison of baseline and week 8.

A standard, parent completed measure of ADHD symptoms. Scale range from 0 (best) to 27 (worst). Unit of Measure - units on a scale. Outcome value reflects change from baseline at endpoint (Week 8).

Laboratory measure of response inhibition. The measure assessed the reaction time in milliseconds (ms) using the Attention Network Task (ANT), which is a computerized test designed to evaluate the efficiency of an attention network. Outcome measure represents a change from Baseline at Week 8 for the ANT - Incongruent reaction time. Lower reaction time is consider a better outcome.
