Design outcomes

Primary

MeasureTime frame
Evidence for specific changes in neuronal activity measured by means of EEG, in relation to drug-related effects over the course of the day.

Secondary

MeasureTime frame
Relationship between EEG parameters, drug-related effects over course of time, neuropsychological testing, level of cognitive performance, results of kidney and liver blood parameters, and interviews regarding the patients' current condition (ADHS-E, Wender Utah Rating Scale short form (WURS-K), Wender-Reimherr-Interview (WRI-V)).
