Critical neurological tests in South Delhi by Dr. Kadam Nagpal (Senior Consultant)
Medical professionals use diagnostic methods and tests to confirm or rule out neurological disorders and other conditions. A century ago, doing an autopsy on a deceased person was the only way to definitively diagnose many neurological illnesses. Dr. Kadam Nagpal, Senior Consultant and Neurologist in Delhi states the advantages to evaluate the living brain and observe nervous system activity through new tools and methods. Neurologist in Delhi may now more accurately identify illnesses and assess how well a certain therapy is working thanks to powerful and precise instruments.
A neurological examination looks for central nervous system issues. The brain, spinal cord, and nerves that originate in these regions make up the central nervous system. Everything people do, including how the muscles move, how organs work, and how they think and plan in detail, is controlled and coordinated by it. More than 600 different central nervous system illnesses exist. A series of tests make up a neurological examination. The balance, muscular strength, and other central nervous system processes are tested during the examination.
Why neurological tests are required?
A neurological examination is done to determine whether a person has a nervous system disorder. The proper treatment can be obtained with an early diagnosis, which may also reduce long-term consequences. If someone exhibits signs of a nervous system problem, they can require a neurological examination. Common symptoms suggested by the best neurologist in South Delhi include headache, issues with balance and/or coordination, numbness in the arms and/or legs, blurred vision, confusion or other changes in mental capacity, weakness, seizures, and exhaustion. Symptoms might vary depending on the disorder. When doing a complete physical or if there is any indication to suspect an underlying issue, it is crucial to conduct a complete and thorough evaluation of the nervous system of the patient. Daily functioning issues might result from nervous system damage. Finding the source and reducing long-term problems may be made easier with early identification.
How does a neurological examination proceed?
A neurologist typically does a neurological examination. A brain doctor who focuses on identifying and treating brain and spinal cord conditions is known as a neurologist. Neurologist in India tests several aspects of the neurological system during the examination. The date, location, and time will be asked by the neurologist or other medical professional. Patients could also be required to do activities. These could involve drawing particular forms, labelling objects, and recalling a list of things. The neurologists can instruct to proceed in a straight line while putting one foot in front of the other. The purpose of a neurological examination is to gauge how well the nervous system is functioning. The nervous system regulates numerous bodily functions and is extremely complicated. The brain, spinal cord, the 12 nerves that emerge from the brain, and the nerves that emerge from the spinal cord make up the nervous system. Also commonly checked is the blood flow to the brain that originates from the arteries in the neck. A neurological examination of newborns and young children includes taking the head circumference.
Common tests to diagnose neurological disorders
Famous neurologist in Delhi, Dr. Nagpal describes some of the additional examinations used to assist in the diagnosis of a neurological illness.
The blood vessels in the brain are impacted by a number of illnesses, including aneurysms, arteriovenous malformations, and vasculitis. The gold standard for diagnosing these disorders is a cerebral angiography. This test is injecting a dye into the brain's blood vessels, followed by an X-ray of the vessels. Through the skull, electroencephalography, or EEG, tracks the electrical activity of the brain. EEG is used to diagnose conditions that cause seizures as well as metabolic, viral, or inflammatory conditions that alter brain activity. The diagnosis of nerve and muscle problems, spinal nerve root compression, and motor neuron illnesses such amyotrophic lateral sclerosis is made using electromyography, or EMG. The electrical activity of the muscles is captured by EMG. An electrical impulse's speed across your nerve is measured by a nerve conduction velocity (NCV) test, also known as a nerve conduction study (NCS). Nerve injury is detectable by NCV.
Children between the ages of one and three years old undergo the Brain Evoked Response Auditory (BERA) hearing test. Early detection of hearing loss in children can be challenging. Speech, language, cognitive, social, and emotional issues can result from hearing loss. Therefore, it will be preferable if youngsters receive a hearing test at a young age. The electrical signal produced at the visual cortex in response to visual stimulation is measured by the visual evoked potential/response (VEP/VER). The occipital cortex has a significant representation of the macula and the central visual field largely activates the visual cortex.
A group of exams known as electronystagmography (ENG) are used to identify abnormalities of involuntary eye movement, vertigo, and balance. In myelography, contrast dye is injected into the spinal canal to improve X-ray or CT imaging of the spine.
What happens after an abnormality is detected?
In the event that any exam results were abnormal, the neurologist would likely request more testing to aid in the diagnosis. A biopsy, a cerebrospinal fluid (CSF) test, imaging tests like an x-ray or an MRI, and blood and/or urine tests are a few examples of these examinations. The brain and spinal cord are surrounded and cushioned by transparent fluid called cerebrospinal fluid (CSF). A little sample of this fluid is taken for a CSF test. A little bit of tissue is removed during a biopsy for further analysis. To confirm a particular diagnosis and look into potential disease-causing factors, neurologists are working to create new and better screening techniques more rapidly and correctly. Researchers will be able to view inside the body more clearly and with less risk because to technological advancements in imaging. These tests and methods will still be crucial clinical research tools for identifying neurological disorders, tracking the course of the disease, and assessing the effectiveness of treatment.

Does the exam include any risks?
The process of getting a neurological check-up is risk-free.
What is the purpose of a neurological exam?
A neurological examination is done to determine whether you have a nervous system issue.
How soon will I get the outcome of my neurological examination?
Immediately following the examination, your neurologist will go through the findings with you.
Do I require any extra testing?
Your neurologist might prescribe additional tests to find out more if findings are not within the expected range. Blood tests, MRI or CT scans, EEG, EMG, NCV, and lumbar puncture tests may be among them.
How is a neurological examination conducted?
The purpose of a neurological examination is to gauge how well the nervous system is functioning.
What is Electromyography (EMG) test?
EMG is used to evaluate the condition of the muscles and the nerve cells that govern them.
What is Electroencephalogram (EEG) test?
EEG is a test that uses tiny, metal discs (electrodes) connected to the scalp to assess electrical activity in the brain.
What is VEP(Visual Evoked Potential) test?
The electrical signal produced at the visual cortex in response to visual stimuli is measured by VEP.
