Trial Summary

What is the purpose of this trial?

The purpose of the study is to use a new method of high-density electroencephalogram (HD-EEG) recording to map brain areas important for movement, sensation, language, emotion, and cognition.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It might be best to ask the trial organizers for more details.

What data supports the effectiveness of the treatment High-density electroencephalogram (HD-EEG) for nervous system disorders?

Research shows that HD-EEG is effective in improving the localization of seizure onset zones in epilepsy, which helps in better clinical management. This suggests that HD-EEG can provide valuable information for treating nervous system disorders by offering more precise brain activity mapping. ^{1 2 3 4 5}

Is HD-EEG safe for use in humans?

HD-EEG has been used safely in clinical settings for epilepsy and sleep research, with no specific safety concerns reported in the available studies. ^{2 3 4 5 6}

How does HD-EEG treatment differ from other treatments for nervous system disorders?

HD-EEG (high-density electroencephalography) is unique because it uses a higher number of electrodes to provide detailed brain activity maps, which can improve the localization of brain abnormalities compared to standard EEG. This enhanced spatial resolution can be particularly useful in diagnosing and managing conditions like epilepsy, where precise localization of the affected brain areas is crucial. ^{3 4 5 6 7}

Eligibility Criteria

This trial is for individuals who can perform specific tasks and give consent on their own. It's suitable for those with epilepsy, healthy subjects, or other nervous system disorders. People with conditions like stroke, tumors, or psychosis that could affect EEG results cannot participate.

Inclusion Criteria

Able to give own consent
