Neurophysiology Care at CritiCare Asia Hospitals, Malad, Mumbai
When symptoms persist but the scans look normal, families are left without an answer, and CritiCare Asia Hospitals is a neurology hospital in Mumbai that looks at how the nervous system functions, not only how it appears. An MRI shows what a nerve looks like. It does not show whether the nerve is working. Neurophysiology closes that gap by studying the nervous system electrically, following how signals pass through the brain, spinal cord, nerves, and muscles in real time. For neurophysiology in Malad, Mumbai, tests are chosen for a specific question, and the results are explained to the patient and family.
Consider a nerve along the inner forearm. A scan may show nothing wrong. Yet if the electrical signal slows by just a few milliseconds as it crosses the elbow, that signals compression that an image would never reveal. Neurophysiology does not take a picture. It records live activity, which can change within seconds.
Why These Tests Are Needed
Many patients come with symptoms that are invisible from the outside: tingling in the fingertips, numbness down the outer leg, short blackouts nobody can explain, or weakness in the muscles with no clear reason. Neurophysiology answers questions that imaging cannot:
- Does the problem lie in the nerve, the muscle, or the brain?
- Is it mild irritation, or real nerve damage?
- Is it confined to one spot, such as the wrist, or more widespread?
For patients who have been told their scans are fine while symptoms continue, neurodiagnostic tests in Malad often give the first solid answer, and that can be the most reassuring part of the process.
Conditions Neurophysiology Helps Diagnose
Our Department of Neurology uses these tests across a broad range of symptoms:
- Peripheral nerve disorders
diabetic neuropathy, carpal tunnel syndrome, ulnar neuropathy at the elbow - Muscle disorders (myopathies)
weakness in the shoulders or thighs, and trouble getting up from a seat - Neuromuscular junction disorders
including Myasthenia Gravis, where nerve-to-muscle signalling becomes unreliable - Brain-related conditions
epilepsy, unexplained fainting, sleep disturbances - Spinal cord involvement
sensory changes running along an arm or leg, and weakness linked to nerve root compression
Types of Neurophysiology Tests
Often more than one test is needed, depending on the pattern of symptoms.
- Electroencephalogram (EEG)
records the brain's electrical activity through small electrodes on the scalp. It usually takes 45 to 60 minutes and is used to look into seizures, unexplained fainting, and sleep disorders. If events are infrequent, video EEG monitoring over a longer period can catch what one session might miss. - Nerve Conduction Study (NCS)
a nerve, most often at the wrist or ankle, is stimulated with a mild electrical impulse and the response is measured further along the same nerve. People often expect a shock; it is more like a brief tap. The test measures conduction speed and signal strength and shows where along the nerve a problem sits. - Electromyography (EMG)
assesses the muscle directly. A fine needle, thinner than a standard injection needle, records electrical activity first at rest and then during controlled movement, and comparing the two patterns helps tell a nerve problem from a muscle one.
A neurophysiology specialist in Malad can help work out which test fits.
What to Expect
- Before the test
You do not need to fast, so eat as usual. Avoid oils or lotions on the arms and legs that day, and wear loose clothing that gives easy access to the forearms, calves, or thighs. Tell the team if you take blood thinners or have a pacemaker. For select tests, such as those used in Myasthenia Gravis workups, certain medicines may need to be paused, but only under medical guidance. - During the test
You stay awake throughout, and most sessions are outpatient. For EEG, you lie still while electrodes are placed on the scalp, and you may be asked to breathe deeply or look at a flashing light. NCS causes a brief twitch, like the thumb jumping when the median nerve is stimulated at the wrist. EMG brings a short pricking feeling as the needle enters the muscle, a few millimetres deep at most. The full session lasts from 30 to 90 minutes depending on the number of tests, and a family member can usually wait close by. - After the test
There is hardly any recovery time, and most patients go back to their day straight away. The neurology team interprets the results and shares them with the referring doctor to guide the next step in diagnosis or treatment.
Neurophysiology Test Results
Results are not a simple pass or fail. Your neurologist reads them with your symptoms, history, and any earlier imaging, because the same electrical pattern can mean different things in different patients. Reports usually take a few days to compile and review. When they are ready, the findings are discussed with you directly, including what they show, what they rule out, and how they shape the treatment plan, and relatives are welcome to join.
Neurophysiology Care at CritiCare Asia Hospitals, Malad, Mumbai
At CritiCare Asia Hospitals, Malad, neurophysiology is not run as a stand-alone lab. It is part of how our neurology team investigates and manages complex cases, and the same team follows the patient from the test through to treatment. Tests are ordered with a particular clinical question in mind, not as a routine add-on, and results feed straight into the plan your neurologist builds. If numbness, weakness or unexplained episodes have not been fully explained by imaging alone, a neurophysiology assessment may be the missing piece. Book a consultation with our neurophysiology specialists in Malad to find out which test is right for you.
