EEG at CritiCare Asia Hospitals, Andheri East, Mumbai
CritiCare Asia Hospitals is a neurology hospital in Mumbai where brain testing is scheduled and reported with the patient's time in mind. Electroencephalography, or EEG, listens in on the brain's electrical activity. Neurons fire tiny impulses constantly, even in sleep, and an EEG captures this as wavy lines that a neurologist can read. Patients needing an EEG test in Andheri East, Mumbai will find it non-invasive, painless, and safe for all ages, from infants of a few months to the elderly. Scalp electrodes deliver no current to the brain; they only record what is already happening.
When Is EEG Recommended
Referrals usually follow a specific event: a blank stare lasting half a minute, sudden jerking of one arm, or a faint without a clear trigger. An EEG specialist in Andheri East can advise promptly on whether a recording is needed. The test is generally recommended when there is:
- Unexplained loss of awareness or a suspected seizure
- Recurrent fainting with no identified cause
- A head injury followed by altered alertness
- Unusual movements or disturbances during sleep
- A need to monitor brain activity in an unconscious or ICU patient
Children need a separate mention. Short "zoning out" spells at school are often dismissed as inattention but can be absence seizures, subtle enough that only an EEG detects them.
Why Is EEG Done
An electroencephalogram test in Andheri East picks up changes in brain activity that indicate a range of conditions. Epilepsy and other seizure disorders are the most frequent reasons for ordering it, and a recording can also show the effects of brain tumours, head trauma, encephalopathy, sleep disorders, brain inflammation and stroke.
In intensive care, continuous EEG monitors unconscious patients and helps judge the appropriate depth of sedation. In specific clinical situations, it also supports confirmation of brain death in a patient in a persistent coma.
Conditions EEG Helps Diagnose
Epilepsy is the condition most associated with EEG, but its role is wider:
- Distinguishing focal seizures from generalised ones
- Identifying patterns linked to brain infections such as encephalitis
- Detecting dysfunction after a stroke
- Flagging metabolic disturbances affecting the brain, since encephalopathy often leaves a distinct signature
- Sleep-related disorders and certain rare conditions, investigated only when clinical suspicion points there
Preparing for an EEG
Preparation takes little time:
- Wash your hair the previous night, without oil or conditioner
- Avoid caffeine for a few hours beforehand
- Continue regular medication unless advised otherwise
- Mild sleep deprivation is sometimes advised, and for children the test may be timed around natural sleep for a cleaner recording
What Happens During the Test
The technician measures the scalp, marks set points, often with a washable pencil, and attaches electrodes with gel or paste. It may feel cool or slightly sticky but is never painful.
During recording, you will typically be asked to:
- Open and close your eyes on cue
- Breathe deeply for a few minutes
- Look at a flashing light
Each step is designed to bring out abnormalities that may not show during quiet rest. A standard EEG lasts 20 to 40 minutes. Video EEG, used when a particular event must be captured on record, can extend to several hours or, in some cases, days.
Understanding the Results
A neurologist trained in EEG interpretation reviews the recording for background rhythm, spikes, and asymmetry. The report may read simply "normal EEG" or note something specific, such as epileptiform discharges in a particular region. Alone, it rarely tells the full story. It is read with your symptoms and clinical history before any diagnosis is finalised.

At CritiCare Asia Hospitals, Andheri East, EEG recordings are interpreted against the clinical question being asked, not read as an isolated printout. Where the first pattern raises a question, the picture is built further through your history and examination, and any follow-up testing is planned together so the patient is not left arranging separate visits. The report is explained in plain language, so it is something you and your doctor can act on.
