Abstract

Objective:

Two measures of the response rate and the optimal treatment response for adult ADHD were evaluated using methylphenidate. The hypotheses were that Prediction of ADHD (PADHD) defines remission, the Weighed Core Symptom (WCS) scale registers direct effects of medication and that WCS may indicate the optimal dose level during titration.

Design:

PADHD and WCS were analyzed at baseline and after intake of low doses of either short-acting or modified-release formulations of methylphenidate, MPH (Study I), during titration with modified-release formulations of MPH (18/27, 36, 54, 72 mg) and at three months follow-up (Study II).

Patients:

Study I consisted of 63 participants (32 females) and Study II consisted of 10 participants (6 females) diagnosed with ADHD and who was to start with treatment.

Outcome measures:

Prediction of ADHD (PADHD) indicates the occurrence of ADHD (No, Yes) and the Weighed Core Symptom scale (WCS) quantifies ADHD from 0 to 100 (max-min).

Results:

The number of clinical cases of ADHD decreased after methylphenidate treatment according to PADHD. WCS increased (p < 0.001) from 9.75 (SD = 12.27) to 47.50 (SD = 29.75) with about 10 mg of methylphenidate (N = 63). During titration, symptoms improved after 18/27 mg and 36 mg of methylphenidate and baseline-follow up comparisons showed WCS increments (p = 0.005) from 31.00 (N = 10, SD = 26.85) to 69.00 (N = 10, SD = 22.34).

Conclusions:

PADHD defined remission and WCS measured therapeutic effects of methylphenidate in adult ADHD.
