Explore the question in detail with explanation, related questions, and community discussions.
An EEG (Electroencephalogram) is a specialized diagnostic test used to measure the electrical activity of the brain. Our brain cells, known as neurons, communicate with each other using tiny electrical signals. These signals can be detected and recorded using electrodes placed on the scalp.
The correct answer is Brain, because EEG provides detailed information about brain wave patterns and is primarily used to diagnose and monitor conditions affecting the central nervous system (CNS).
Epilepsy and Seizures: EEG is the most common diagnostic tool for detecting abnormal brain wave patterns in epilepsy patients.
Sleep Disorders: It is widely used in sleep studies to identify insomnia, narcolepsy, and sleep apnea.
Brain Tumors and Injuries: EEG can help detect unusual brain activity linked to tumors or head trauma.
Dementia and Alzheimer’s Disease: It can show brain dysfunction associated with neurodegenerative disorders.
Monitoring during Surgery: EEG is used in certain brain and heart surgeries to ensure proper brain activity.
Heart (A): Heart disorders are diagnosed using ECG (Electrocardiogram), not EEG.
Kidneys (C): Kidney function is tested through blood and urine tests, not brain wave recordings.
Lungs (D): Lung problems are diagnosed with imaging (X-rays, CT scans) or pulmonary function tests.
EEG is a safe, painless, and non-invasive test. Patients simply have electrodes attached to their scalp with a conductive gel. The procedure records brain wave patterns like alpha, beta, delta, and theta waves, which doctors analyze to identify abnormalities.
In conclusion, EEG is an essential tool in modern medicine for diagnosing ailments of the brain, especially epilepsy and other neurological disorders.
