EEG at CritiCare Asia Hospitals, Malad, Mumbai
When someone in the family has an unexplained episode, a clear answer matters, and CritiCare Asia Hospitals is a neurology hospital in Mumbai where families are walked through each step of brain testing. Electroencephalography, or EEG, is a test that listens to the brain's own electrical activity. Neurons fire small impulses without pause, even in deep sleep, and the EEG turns that activity into wavy lines that a neurologist can interpret. For an EEG test in Malad, Mumbai, the process is painless, non-invasive, and safe from infancy into old age. Small electrodes on the scalp do not send current into the brain; they simply record what is already there.
When Is EEG Recommended
The test is usually advised after something has happened. Someone stares blankly for half a minute, one arm jerks suddenly, or a faint comes with no obvious trigger. Families are often the ones who witness these moments, and an EEG specialist in Malad can advise whether a recording is needed. The test is commonly recommended for:
- Loss of awareness without explanation, or a suspected seizure
- Repeated fainting with no known cause
- A head injury followed by altered alertness
- Odd movements or disturbances during sleep
- Monitoring brain activity in an unconscious or ICU patient
In children, short "zoning out" spells at school are frequently taken for inattention. Sometimes they are absence seizures, which are subtle enough that only an EEG picks them up.
Why Is EEG Done
An electroencephalogram test in Malad detects changes in brain activity that point to a number of conditions. Epilepsy and other seizure disorders are the leading reason for requesting one, but a recording may also reflect brain tumours, head trauma, encephalopathy, sleep disorders, brain inflammation and the after-effects of stroke.
In intensive care, continuous EEG is used to monitor unconscious patients and to judge how deeply they should be sedated. In particular clinical circumstances, it also helps confirm brain death in a patient in a persistent coma.
Conditions EEG Helps Diagnose
Epilepsy is the condition most linked with EEG, yet the test reaches further:
- Separating focal seizures from generalised ones
- Recognising patterns associated with brain infections such as encephalitis
- Finding dysfunction that follows a stroke
- Flagging metabolic disturbances of the brain, as encephalopathy often leaves a distinct signature
- Sleep-related disorders and certain rare conditions, which are looked into only when clinical suspicion points directly to them
Preparing for an EEG
Little is needed beforehand:
- Wash the hair the night before, with no oil or conditioner
- Skip caffeine for a few hours before the test
- Carry on with regular medication unless the doctor says otherwise
- Expect that mild sleep deprivation is occasionally advised, and that for children the test is sometimes scheduled around natural sleep to give a cleaner recording
What Happens During the Test
The technician first measures the scalp and marks set points, often with a washable pencil, then attaches electrodes using gel or paste. The sensation may be cool or slightly sticky, and it is never painful.
When the recording begins, you will usually be asked to:
- Open and close your eyes when told
- Breathe deeply for a few minutes
- Look at a flashing light
Every step has a purpose, which is to bring out abnormalities that may stay hidden at quiet rest. A standard EEG takes 20 to 40 minutes. Video EEG, used when a particular event has to be captured on record, can last several hours or, in some cases, days. A family member can usually stay close, which helps children in particular.
Understanding the Results
A neurologist trained in EEG interpretation examines the raw recording for background rhythm, spikes, and asymmetry. The report may say simply "normal EEG", or it may describe something specific, such as epileptiform discharges in one region. A report seldom tells the whole story by itself. It is read together with your symptoms and history before a diagnosis is settled.
EEG at CritiCare Asia Hospitals, Malad, Mumbai
At CritiCare Asia Hospitals, Malad, EEG recordings are read in light of the clinical question behind them, not as a stand-alone printout. When the first pattern raises a question, the picture is developed further by linking it with your history and examination, and the same neurology team follows the patient from the recording through to the next step. Results are explained to the patient and family in plain terms, so the report becomes something everyone can act on. If you have noticed unexplained episodes, unusual movements during sleep, or symptoms that suggest a seizure, speak with our neurologists in Malad at CritiCare Asia Hospitals for an EEG test.
