EEG : Preparation Instructions

What is an Electroencephalogram (EEG)?

An electroencephalography (EEG) is a diagnostic test that detects abnormalities and variances in your brain waves, or in the electrical activity of your brain. During the procedure, a technician will affix electrodes consisting of small metal discs with thin wires onto your scalp. These electrodes can then detect tiny electrical charges that result from the activity of your brain cells. This procedure is non-invasive. EEG may aid in the diagnosis of seizures/epilepsy, sleep disorders, head injuries, encephalopathies and dementias, as well as brain tumors.

The Process of EEG

During the EEG procedure, your brain’s electrical signals are captured and recorded on a computer. This EEG brain wave test is a comprehensive way to map out the various functionalities and activities occurring within your brain, aiding in the diagnosis of several conditions.

Conditions Diagnosed with EEG

The EEG serves as a powerful tool in diagnosing a variety of conditions including, but not limited to seizures/epilepsy, sleep disorders, head injuries, encephalopathies, dementias, and even brain tumors.

• Epilepsy Diagnosis Epilepsy, characterized by recurrent seizures, can be effectively diagnosed through an EEG. It helps identify abnormal electrical activities in the brain typically seen during seizures.

• Sleep Disorders EEG is also instrumental in diagnosing sleep disorders, assisting in the analysis of sleep patterns and identifying any disruptions in brain waves affecting sleep quality.
