Neurophysiology Care at CritiCare Asia Hospitals, Andheri East, Mumbai
CritiCare Asia Hospitals is a neurology hospital in Mumbai where nervous system testing is organised so that patients can complete the tests they need without repeated visits. An MRI shows what a nerve looks like, but not whether it is working. Neurophysiology fills that gap by studying the nervous system electrically, tracing how signals move through the brain, spinal cord, nerves and muscles in real time. For neurophysiology in Andheri East, Mumbai, the tests are selected for a specific clinical question and planned together.
Take a nerve along the inner forearm. A scan can look completely normal, yet if the electrical signal slows by even a few milliseconds crossing the elbow, that indicates compression that an image would never catch. Neurophysiology records live activity, which can change within seconds, instead of taking a picture.
Why These Tests Are Needed
Many patients present with symptoms that do not show on the outside: tingling fingertips, numbness down the outer leg, brief blackouts that nobody can explain, or muscle weakness without an obvious cause. Neurophysiology answers the questions imaging cannot:
- Is the problem in the nerve, the muscle, or the brain itself?
- Is it mild irritation or actual nerve damage?
- Is it localised, such as at the wrist, or more widespread?
For patients whose scans look fine but whose symptoms persist, neurodiagnostic tests in Andheri East often bring the first concrete answer.
Conditions Neurophysiology Helps Diagnose
Our Department of Neurology uses these tests across a wide symptom range:
- Peripheral nerve disorders
diabetic neuropathy, carpal tunnel syndrome, ulnar neuropathy at the elbow - Muscle disorders (myopathies)
weakness in the shoulders or thighs, difficulty rising from a seated position - 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 travelling along an arm or leg, and weakness linked to nerve root compression
Types of Neurophysiology Tests
More than one test is often required, depending on the pattern of symptoms.
- Electroencephalogram (EEG)
records the brain's electrical activity through small scalp electrodes. It typically takes 45 to 60 minutes and evaluates seizures, unexplained fainting, and sleep disorders. When events are infrequent, video EEG monitoring over a longer stretch can capture what a single session might miss. - Nerve Conduction Study (NCS)
stimulates a nerve, most commonly at the wrist or ankle, with a mild electrical impulse and measures the response further along the same nerve. It is closer to a brief tap than a shock, and it measures conduction speed and signal strength while pinpointing where a problem sits. - Electromyography (EMG)
assesses the muscle directly. A fine needle, thinner than a standard injection needle, records electrical activity at rest and then during controlled movement. Comparing the two patterns helps separate a nerve problem from a muscle one.
A neurophysiology specialist in Andheri East can advise which test is appropriate.
What to Expect
- Before the test
No fasting is required; eat normally. Skip oils or lotions on the arms and legs that day, and wear loose clothing that allows easy access to the forearms, calves or thighs. Tell the team if you are on blood thinners or have a pacemaker. For select tests, such as those used in Myasthenia Gravis workups, certain medications may need to be paused, but only under medical guidance. - During the test
You are awake throughout, and most sessions are outpatient. EEG involves lying 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, similar to the thumb jumping when the median nerve is stimulated at the wrist. EMG brings a short pricking sensation as the needle enters the muscle, a few millimetres deep at most. Depending on how many tests are required, the full session runs 30 to 90 minutes, and where several tests are needed, they are arranged together in one visit. - After the test
There is no real recovery period, and most patients resume their day immediately. The neurology team interprets the results and shares them with the referring doctor to shape the next step in diagnosis or treatment.
Neurophysiology Test Results
Results are not a simple pass or fail. Your neurologist reads them alongside your symptoms, history, and any imaging already done, since the same electrical pattern can point to different causes in different patients. Reports typically take a few days to compile and review. Once ready, findings are discussed with you directly, covering what they show, what they rule out, and how they shape the treatment plan.
Neurophysiology Care at CritiCare Asia Hospitals, Andheri East, Mumbai
At CritiCare Asia Hospitals, Andheri East, neurophysiology is not run as a standalone lab. It is built into how our neurology team investigates and manages complex cases. Tests are ordered with a specific clinical question in mind, not as a routine add-on, and results feed directly into the treatment 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 Andheri East to find out which test is right for you.
