Frequently Asked Questions

A nerve conduction study (NCS/NCV) measures how quickly and effectively electrical signals travel along peripheral nerves. Needle EMG records the electrical activity of selected muscles. These tests are often performed together to assess symptoms such as numbness, tingling, burning pain, radiating pain, or weakness and to help identify peripheral neuropathy, nerve compression such as carpal tunnel syndrome, nerve-root problems, and selected muscle disorders.

Keeping consistent sleep and wake times, reducing caffeine later in the day, setting aside time to write down worries, and following a quiet wind-down routine may help. If racing thoughts are persistent, distressing, or affecting sleep or daytime functioning, an assessment can help identify insomnia, anxiety, mood symptoms, medication effects, or other contributing factors. Persistent insomnia may benefit from structured treatment such as cognitive behavioural therapy for insomnia (CBT-I).

Yes, anxiety can cause these symptoms. However, they can also occur with heart, lung, or other medical conditions and should not automatically be attributed to anxiety. New, severe, persistent, or exertional symptoms—or symptoms accompanied by fainting, sweating, or pain spreading to the arm, back, neck, or jaw—require urgent medical assessment.

Obstructive sleep apnea repeatedly narrows or blocks the upper airway during sleep, disrupting sleep and sometimes lowering oxygen levels. It can contribute to daytime sleepiness or fatigue, poor concentration, morning headaches, irritability, and low mood. Loud snoring, choking or gasping during sleep, and witnessed pauses in breathing are important warning signs. Because these symptoms can have several causes, a clinical assessment helps determine whether sleep apnea testing is appropriate.

A memory loss or dementia evaluation begins with a detailed history from the patient and family, medication review, assessment of daily functioning, a physical and neurological examination, and cognitive testing. Blood tests may identify reversible contributors, and an MRI brain or CT scan may be recommended. EEG is not a routine test for dementia; it is used in selected situations, such as suspected seizures or an atypical or rapidly fluctuating presentation.

Migraine can cause a moderate to severe headache that is often—but not always—one-sided or throbbing. It may be accompanied by nausea, sensitivity to light or sound, and sometimes aura. Triggers vary between people and may include stress, poor sleep, skipped meals, hormonal changes, and certain sensory or dietary factors.

An overnight polysomnography (PSG) records brain waves, eye and limb movements, muscle activity, breathing, oxygen level, heart rhythm, snoring, and body position during sleep. It can help diagnose obstructive sleep apnea and assess selected conditions such as sleep-related movements, unusual behaviours during sleep, and certain causes of excessive daytime sleepiness. A PSG is not required for every sleep problem; the appropriate type of sleep study depends on the clinical question and the patient’s circumstances.

EEG is non-invasive and usually painless. NCS/NCV uses brief electrical impulses that may cause a short tingling or shock-like sensation. Needle EMG is minimally invasive because it uses a fine needle electrode and may cause brief discomfort. These tests generally do not require sedation or recovery time.

You should consider a neurology evaluation if you have persistent headaches or migraine, seizures or "spells," dizziness or balance problems, memory concerns, burning feet, numbness, tingling, or nerve pain. Jain Healthcare Network evaluates these symptoms through an integrated Brain–Mind–Sleep approach in Sector 56, Gurugram.
