What conditions can EEG help diagnose in addition to epilepsy?

EEG, or electroencephalography, is a valuable diagnostic tool that records brain activity by measuring electrical signals. While it is widely recognized for its role in diagnosing epilepsy, it is also useful for identifying various other conditions.

Sleep disorders can be effectively diagnosed using EEG, as it can help differentiate between different sleep states and detect abnormalities such as sleep apnea or parasomnias. The brain's electrical activity during sleep provides critical insights into sleep architecture and possible disruptions.

Additionally, EEG is instrumental in determining brain death. In this context, the absence of electrical activity over a specified period indicates that brain function has ceased, which is crucial for confirming brain death when aligned with clinical criteria.

In contrast, the other options either suggest a misunderstanding of EEG capabilities or limit its application too narrowly, which is why they are not considered correct. Recognizing the broader scope of EEG in assessing neurological conditions highlights its importance beyond just epilepsy.
