For Doctors

EEG (Electroencephalogram) records the brain’s electrical activity through electrodes placed on the scalp, and is commonly used to help evaluate epilepsy, seizures and certain brain disorders.

• Epilepsy (মৃগী)
• Seizures (ফিট)
• Encephalopathy and other brain disorders (ব্রেন ডিজঅর্ডার)
• Unexplained blackouts or staring spells

Video EEG combines continuous EEG recording with synchronised video, helping correlate brain-wave changes with what is physically happening during an event such as a seizure.

• Suspected epilepsy where a routine EEG was inconclusive
• Distinguishing epileptic seizures from non-epileptic events
• Characterising seizure type before treatment planning

NCV (Nerve Conduction Study) evaluates how well and how fast nerves transmit electrical signals, and is commonly used to assess conditions such as peripheral neuropathy and carpal tunnel syndrome.

• Peripheral neuropathy
• Diabetic neuropathy
• Carpal tunnel syndrome
• Radiculopathy (spine-related nerve issues)
• Plexopathy

EMG (Electromyography) measures the electrical activity of muscles, helping assess how well muscles respond to nerve signals in conditions such as myopathy and motor neuron disease.

• Myopathy (muscle-related weakness)
• Motor neuron disease
• Radiculopathy (nerve-root problems)
• Unexplained muscle weakness or wasting

VEP (Visual Evoked Potential) evaluates the visual pathway from the eyes to the brain, and can help in assessing conditions such as optic neuritis and multiple sclerosis.

• Suspected optic neuritis
• Assessing the visual pathway in demyelinating conditions such as multiple sclerosis
• Unexplained visual disturbance where an eye cause has been ruled out

BERA/ABR evaluates the hearing pathway up to the brainstem, and is often used to screen hearing in infants and to help identify conditions such as acoustic neuroma.

• Newborn and infant hearing screening
• Suspected acoustic neuroma
• Assessing hearing pathway function where a routine hearing test is inconclusive

SSEP tests how well sensory signals travel from the limbs to the brain along the spinal cord, helping assess spinal cord and peripheral nerve pathway function.

• Suspected spinal cord pathway involvement
• Evaluating sensory nerve pathway function alongside NCV/EMG
• Certain demyelinating or compressive nerve conditions

Blink Reflex testing evaluates the nerve pathway connecting the trigeminal and facial nerves, helping assess conditions affecting facial nerve function or the brainstem.

• Suspected facial nerve (Bell’s palsy) involvement
• Evaluating trigeminal nerve function
• Certain brainstem conditions affecting the blink reflex pathway

Single-Fiber EMG is a specialised nerve-muscle test used to help evaluate conditions affecting the neuromuscular junction, such as Myasthenia Gravis.

• Suspected Myasthenia Gravis
• Other suspected neuromuscular junction disorders where RNST findings are inconclusive

RNST (Repetitive Nerve Stimulation Test) helps detect neuromuscular junction disorders and is commonly used for diagnosing Myasthenia Gravis.

• Suspected Myasthenia Gravis
• Unexplained fatigable muscle weakness, especially affecting the eyes or face

Sleep studies monitor body functions during sleep to help identify sleep-related breathing and neurological conditions.

• Suspected sleep apnoea
• Unexplained excessive daytime sleepiness
• Certain movement disorders during sleep

Polysomnography (PSG) is a comprehensive overnight sleep study that records brain activity, breathing, oxygen levels, heart rhythm and body movement to evaluate sleep disorders in detail.

• Suspected obstructive sleep apnoea
• Detailed evaluation where a basic sleep study is inconclusive
• Certain neurological movement disorders during sleep

Neurodiagnostic tests such as EEG, NCV, VEP and BERA/ABR performed on children, with the preparation and pace adapted to the child.

• EEG for seizures, blank spells or febrile convulsions
• BERA/ABR hearing assessment, including in infants
• VEP for visual pathway assessment
• NCV/EMG for weakness or suspected nerve and muscle conditions
