Outcome measures
Primary outcome
The main endpoints for the cognitive tasks are the behavioral score on the immediate and delayed recall of the VLT. This includes the number of words recalled immediately and after a 20 minute delay.
Secondary outcome
Secondary, to establish the pharmacokinetic and pharmacodynamics profile of biperiden the primary endpoints will be the blood serum values and physiological measures (body temperature, blood pressure, heart rate and pupil size). Furthermore the behavioral outcomes of the n-back and simple and choice reaction tasks will be used for analysis, as well as the scores on the B&L and complaints questionnaire. Next to this, the event-related potentials during the behavioural tasks will be analysed. Another important measure is the brain response to the novelty oddball task, which will give an indication of the role of acetylcholine in novelty processing.
Intervention
Subjects will participate in 3 treatment conditions: i.e. placebo, biperiden 2 mg and 4 mg. All medications will be administered orally. Order of treatments will be balanced over three test sessions, which will be separated by a washout period of at least 7 days.
