Did youknow that years ago the only way to positively diagnose a neurological disorderwas to perform an autopsy after someone died. Nowadays there are manydiagnostic tools medical professionals can use to rule out the presence ofneurological disorder. Most tools focus on diagnostic imaging. Significantchanges have been made in this area of diagnosis. However, advancements havealso been made in the use of screening tests and other diagnostic tests.
Common Neurological Screening Tests Laboratory tests – these involve theuse of collecting blood, urine, or other bodily fluid samples to diagnosedisease. Medical professionals will order a laboratory test to get general informationor identify specific concerns. Take for example a brain or spinal cordinfection. Blood tests can detect the microorganism causing that infection.Blood tests can also confirm for the presence of toxins directly affecting thenervous system or identify if hemorrhaging is a factor.
Genetic tests – recall that someneurological disorders are hereditable. They may occur due to a geneticcondition. Thus, genetic testing can identify neurological disorders in utero.This means a pregnant woman can take this test to determine whether her growingchild is at risk for developing a neurological disorder. For example, pregnantwomen can have an amniocentesis.This procedure takes a sample of the amniotic fluid in the womb. The fluid istested for possible markers that correlate to genetic defects the fetus may beat risk for developing.
MedicalProfessional Preparing to Perform an Amniocentesis 839325602 Diagnostic imaging of neurological Disorders After a medical professional performsa neurological exam, reviews patient history and views results of screeningtests they may order a specific diagnostic test. The following provides a listof some common diagnostic tests, which includes imaging: · Angiography –this test is common to both problems associated with the nervous andcardiovascular system. It is used to detect blockages in the arteries or veins.Commonly this is performed to diagnose strokes in a person.
The patientundergoes this test in an imaging room. With the help of a dye, the medical professionalcan use X-rays to identify where any obstruction is present. · Computed Tomography (CT) Scan – this is a noninvasive imaging procedurethat allows medical professionals to view organs, bones, and tissues.
Specifically, the neurological CT scan shows images of the brain and spine (Fig9.1) Medical professionals willorder a CT scan for many reasons such as detecting a brain tumor, identify ablood clot or pinpoint where brain damage happened from trauma.
