EEG at CritiCare Asia Hospitals, Kurla, Mumbai
CritiCare Asia Hospitals is a neurology hospital in Mumbai where brain testing is explained to the patient before it is carried out. Electroencephalography, or EEG, listens in on the brain's own electrical activity. Every neuron fires tiny impulses all the time, even at 2 a.m. while you sleep, and an EEG records that activity as wavy lines a neurologist can read. Patients who need an EEG test in Kurla, Mumbai can expect a straightforward procedure. It is non-invasive, painless, and safe across age groups, from infants a few months old to elderly patients. The electrodes placed on the scalp send no current into the brain; they only record what is already happening.
When Is EEG Recommended
Most referrals follow an actual event. A patient staring blankly for half a minute. Sudden jerking of one arm. A faint with no clear trigger. An EEG specialist in Kurla may advise the test when there is:
- An 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 deserve a separate mention. Brief "zoning out" spells at school are often put down to inattention, but occasionally they are absence seizures, subtle enough that only an EEG catches them.
Why Is an EEG Done
An electroencephalogram test in Kurla picks up changes in brain activity that point towards a range of conditions. Epilepsy and other seizure disorders are the most common reason it is ordered. The list runs wider, though: brain tumours, head trauma, encephalopathy, sleep disorders, brain inflammation and the effects of stroke can all show up on a recording.
In intensive care, continuous EEG helps monitor unconscious patients and judge the right depth of sedation. In specific clinical situations, it is also used to help confirm brain death in a patient in a persistent coma.
Conditions EEG Helps Diagnose
Epilepsy is the condition most associated with EEG, but its use extends well beyond it:
- Telling focal seizures from generalised ones
- Identifying patterns linked to brain infections such as encephalitis
- Picking up dysfunction after a stroke
- Flagging metabolic disturbances that affect the brain, since encephalopathy often leaves a distinct signature
- Sleep-related disorders and certain rare conditions, pursued only when clinical suspicion points there directly
Preparing for an EEG
Preparation is simple:
- Wash your hair the night before, without oil or conditioner
- Avoid caffeine for a few hours beforehand
- Continue regular medication unless told otherwise
- Be ready for mild sleep deprivation, which is occasionally advised; for children the test is sometimes timed around natural sleep for a cleaner recording
What Happens During the Test
The technician begins by measuring the scalp and marking specific points, often with a washable pencil, before attaching electrodes with gel or paste. It can feel cool or slightly sticky against the skin, but never painful.
Once recording starts, you will typically be asked to:
- Open and close your eyes on cue
- Breathe deeply for a few minutes
- Look at a flashing light
None of this is arbitrary. Each step is designed to bring out abnormalities that may not appear during quiet rest. A standard EEG runs 20 to 40 minutes. Video EEG, used when a specific event needs to 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 raw recording for background rhythm, spikes, and asymmetry. The report may be as simple as "normal EEG", or it may note something specific such as epileptiform discharges in a particular region. On its own, a report rarely tells the whole story. It is read alongside your symptoms and clinical history before any diagnosis is finalised, and a normal recording does not always rule out a seizure disorder.
EEG at CritiCare Asia Hospitals, Kurla, Mumbai
At CritiCare Asia Hospitals, Kurla, 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 by correlating it with your history and examination. We explain the findings in plain language, including what they mean and what happens next, so the report is something you and your doctor can act on. If you have noticed unexplained episodes, unusual movements during sleep, or symptoms suggestive of a seizure, speak with neurologists in Kurla at CritiCare Asia Hospitals for an EEG test.
