Is a signed informed consent required for an EEG?

A signed informed consent is typically not required for an electroencephalogram (EEG) because the procedure is generally considered non-invasive and low-risk. Patients may be informed about the test, its purpose, and what it entails, but formal consent is not mandated in the same way it might be for more invasive procedures.

Informed consent focuses on patient autonomy and understanding, ensuring that individuals are aware of the treatment or diagnostic steps they are about to undergo. For an EEG, while it is still important for healthcare providers to explain the procedure to ensure patient comfort and understanding, the regulatory framework does not classify it as requiring formal consent in all circumstances.

For procedures classified as more invasive or those with higher risks, such as surgeries or certain diagnostic tests like lumbar punctures, a signed consent form would be necessary to indicate that the patient understands the risks involved. Here, the EEG's non-invasive nature plays a critical role in the absence of a strict consent requirement.
