Neurology Care - Diagnosis
CT scan: CT scan is an imaging procedure which uses X-rays to produce cross-sectional images of the body. This fast and painless procedure aids in diagnosing brain damage from a head injury, detecting blood clots in the brain, brain tumors and cysts, detecting spinal stenosis, and many more. The images of CT scan can give more detailed information about your internal organs and their injuries which plain X-rays cannot.
Carotid Ultrasound:Â This diagnostic technique uses high-frequency sound waves to look at the structure and function of the carotid arteries which runs on either side of your neck. This test shows whether fatty deposits called plaque has clogged or narrowed the carotid arteries. Narrowed carotid arteries reduce the blood flow to the brain and increase the risk of stroke.
Electroencephalogram (EEG): An EEG is a diagnostic procedure to detect the abnormalities in the brain waves by attaching electrodes consisting of flat metal discs to the scalp. This test, in which the result is observed as wavy lines on a computer screen, is paramount in diagnosing several types of brain disorders mainly epilepsy and sleep disorders.
Video Telemetry: This is an important test in the diagnosis and classification of epilepsy, especially in children. This involves continuous video and EEG monitoring of the patient for a period of 1-5 days.
Electromyography (EMG):Â Electromyography (EMG) is an electro diagnostic medicine technique which measures how well the muscles respond when the nerves are stimulated. During this test, small needles (or electrodes) are inserted into the muscles to pick up the electrical activity in those muscles. The resulting signals are converted into graphs, sounds or numerical values that help the doctors to diagnose the problems with nerve-to-muscle signal transmission, nerve dysfunction or muscle dysfunction.
Lumbar Puncture (Spinal Tap):Â Lumbar Puncture is performed to acquire information about the cerebrospinal fluid that surrounds the brain and spinal cord. This test involves inserting a needle between the two lumbar bones in the lower back to withdraw a sample of the fluid. Meningitis, Guillain-Barre syndrome, multiple sclerosis, cancers in the spinal cord or brain are a few conditions which can be diagnosed by this test.
Tilt Table Test:Â This simple and non-invasive test is conducted to determine the cause of repeated and unexplained episodes of fainting (called syncope). As the name implies, this test involves placing the patient on a special table supported with firm straps and tilting it to different angles. During this tilting, the body's vital signs like heart rhythm, pulse and blood pressure are constantly monitored by the doctor to investigate the cause of fainting.
