Timeline

Summary

This trial will investigate how an anticholinergic drug affects areas of the brain involved in memory and brain activity. Participants will receive the drug or a placebo to compare brain activity changes.

Who is the study for?
This trial is for adults aged 18-55 with epilepsy, in good health otherwise, and scheduled for intracranial surgery. They must have a BMI of 18-35 kg/m2 and be able to consent. Excluded are those with significant health issues like heart problems, liver failure, certain neurological conditions, glaucoma, gastrointestinal blockages or pregnant women.
What is being tested?
The study tests how scopolamine affects memory-related brain activity in epileptic patients during surgery. Participants receive either the drug or a placebo on different days while completing memory tasks. Brain activity is recorded to see if scopolamine influences memory encoding or retrieval.
What are the potential side effects?
Scopolamine can cause dry mouth, blurred vision, dizziness, confusion and difficulty urinating. It may also worsen conditions like BPH (enlarged prostate), narrow-angle glaucoma or myasthenia gravis.

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives

Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: Scopolamine (0.4mg)Experimental Treatment1 Intervention
Subjects will receive a dose of scopolamine (0.4mg) on each day. Approximately 15 minutes after administration, the participant will then complete either an episodic or a spatial memory task session. If the patient completed the sham session already, this session will take place the day following the initial session, or at least four half-lives after the first session.
Group II: PlaceboPlacebo Group1 Intervention
Subjects will receive saline (0.4mg) via IV on each day. Approximately 15 minutes after administration, the participant will then complete either an episodic or a spatial memory task session. If the patient completed the scopolamine session already, this session will take place the day following the initial session, or at least four half-lives after the first session.
