The objective of the study is to test the effects of the p-glycoproteine transporter on cognitive test in healthy volunteers and to explore the effects of the p-glycoproteine transporter on functional Magnetic Resonance Imaging (fMRI).
The specific goals of the study are:- To identify which dose(s) of mecamylamine cause cognitive and memory impairment as demonstrated using the NeuroCart CNS test battery- To investigate the safety and tolerability of mecamylamine by comparison with…
Primary Objectives:• Assess the pharmacokinetic (PK) and pharmacodynamic (PD)/efficacy effects of 3 different single doses of EVP-6124 vs. placebo;• Assess the PK and PD/efficacy effects of the different combinations of 2 doses of donepezil and 3…
The primary objective is to examine whether a memory impairment as a result of biperiden treatment (cholinergic M1 antagonist) will be increased by acute tryptophan depletion (ATD, a drink that decreases serotonin synthesis). In other words, we will…
The primary objective is to examine whether a memory impairment as a result of biperiden treatment (cholinergic M1 antagonist) can be reversed by rivastigmine (a cholinesterase inhibitor). Secondary, we will assess the effects of biperiden and…
• To determine the profile of CNS effects at several time points after 2 mg and 4 mg biperiden in comparison to placebo in healthy elderly subjects.• To investigate the safety and tolerability of biperiden in healthy elderly subjects.• To determine…
We will examine the cognitive performance of healthy young participants at different time points after a single administration of biperiden. The behavioural outcomes and electrophysiological correlates will be linked with the serum levels of…
Scar volume and POSAS score will be measured in the Verapamil group, these will be compared to the scar volume and POSAS score in the Kenacort+Verapamil group and the Kenacort group. In addition, complications/ adverse effects will be reported.
