Which condition can be diagnosed using an EEG?

An EEG, or electroencephalogram, is a diagnostic test that measures electrical activity in the brain. It is particularly useful in identifying and diagnosing disorders that affect brain function. Epilepsy, characterized by recurrent seizures due to abnormal electrical activity in the brain, can be effectively diagnosed using an EEG. The test can detect specific patterns of electrical activity that are associated with seizure disorders, making it an essential tool in confirming an epilepsy diagnosis.

In contrast, asthma, diabetes, and heart disease are conditions that do not primarily involve the brain's electrical activity and are diagnosed using different medical tests and evaluations. Asthma is typically diagnosed through pulmonary function tests and clinical assessment of respiratory symptoms. Diabetes is diagnosed by measuring blood glucose levels and assessing the patient's history and symptoms. Heart disease is evaluated through cardiac imaging, stress tests, and other cardiovascular assessments. Thus, the EEG's primary role in monitoring and diagnosing neurological conditions distinctly aligns with epilepsy.
