Diagnosing For A Cure

How does it work?

It is my sincere hope that one day we will have enough information about the underlying causes of these and other disorders that we might be able to help each and every child who suffers from a debilitating disorder.

When the brain is scanned, "the part of the brain that’s active receives more oxygen-rich blood than less active areas. That shows up on a brain scan as a bolder, brighter image. This allows researchers to look at which part of the brain is active when people are doing different types of tasks" (Morin, 2014, p.1)Physicians will use the information they have gathered from the brain scans in order to develop a plan of action or prescribe appropriate medications to help decrease symptoms or remove the symptoms altogether.

Diagnosing for a cure

Due to my background with special education, I find it very exciting that modern medical practices are getting to the root of common learning disorders like Dyslexia and HDHD. There have even been recorded studies where brain scans are diagnosing more severe types of learning disorders such as Autism Spectrum and Asperger's syndrome. Researchers are developing new ways to treat the causes and not just the symptoms of these disorders which is essentially helping some of these children, and also adults, overcome their disorders all together! Truly fascinating!

What should you expect during an fMRI scan?"Most MRI exams are painless. However, some patients find it uncomfortable to remain still during MR imaging. Others experience a sense of being closed-in (claustrophobia). Therefore, sedation can be arranged for those patients who anticipate anxiety, but fewer than one in 20 require medication" (RSNA, 2015)."It is normal for the area of your body being imaged to feel slightly warm, but if it bothers you, notify the radiologist or technologist. It is important that you remain perfectly still while the images are being recorded, which is typically only a few seconds to a few minutes at a time. For some types of exams, you may be asked to hold your breath" (RSNA, 2015). "You will know when images are being recorded because you will hear tapping or thumping sounds when the coils that generate the radiofrequency pulses are activated. You will be able to relax between imaging sequences, but will be asked to maintain your position as much as possible" (RSNA, 2015)."You will usually be alone in the exam room during the MRI procedure. However, the technologist will be able to see, hear and speak with you at all times using a two-way intercom. Many MRI centers allow a friend or parent to stay in the room as long as they are also screened for safety in the magnetic environment" (RSNA, 2015)."You may be offered or you may request earplugs to reduce the noise of the MRI scanner, which produces loud thumping and humming noises during imaging. Children will be given appropriately sized earplugs or headphones during the exam. MRI scanners are air-conditioned and well-lit. Some scanners have music to help you pass the time" (RSNA, 2015)."When the contrast material is injected, it is normal to feel coolness and a flushing sensation for a minute or two. The intravenous needle may cause you some discomfort when it is inserted and once it is removed, you may experience some bruising. There is also a very small chance of irritation of your skin at the site of the IV tube insertion" (RSNA, 2015)."If you have not been sedated, no recovery period is necessary. You may resume your usual activities and normal diet immediately after the exam. A few patients experience side effects from the contrast material, including nausea and local pain. Very rarely, patients are allergic to the contrast material and experience hives, itchy eyes or other reactions. If you experience allergic symptoms, a radiologist or other physician will be available for immediate assistance" (RSNA, 2015)

Functional Magnetic Resonance Imaging, or fMRI

My PredictionWhat I think will happen?

Method How do they do it?

Once Doctors are able to determine which areas of the brain are being affected, they can recomend the best treatment options for the patient.
