• Common Neurological Diagnostic Screening Tests

    Diagnostic tests are important tools that physicians use to determine if an individual is suffering from a certain disease. It gives them the chance to save a person’s life by providing the right treatment plan based on the test results. Neurological diagnostic tests are used to determine if a person is suffering from a neurological problem.

    Neurological disorders are not easy to determine and one cannot rely on symptoms alone. Centuries ago, a person would die and physicians would only find out that the person died from neurological disorder after they performed an autopsy.

    Today, physicians have access to tools that help them determine brain activity with clearer, bigger, and a more detailed image, making it easy for them to come up with a diagnosis. Technological advancements now allow faster and more accurate test results. Here are the most common neurological diagnostic screening tests used today:

    • Laboratory screening tests like urine, blood and other substances are used to determine presence of disease, monitor levels of therapeutic drugs, and to better understand the disease process. A physician orders tests to get both general and specific information on a person’s health. Analysis of neurological fluids provides information on the central nervous system’s activity and possible infections.
    • Genetic testing or counseling helps determine if individuals with a family history of neurological disorders carry the gene that is responsible for the disorder, or if their children are affected by the disorder. Genetic testing can determine various types of neurological disorders. Genetic tests include the following:

    • Amniocentesis is performed during 14-16 weeks of pregnancy. Amniotic fluid is collected from the womb and is tested for any genetic defects that may affect the fetus.
    • Chorionic villus sampling or CVS is done by collecting and testing a small amount of placenta during early stages of pregnancy. The placenta carries the same DNA as the embryo and is used to determine any genetic abnormalities.
    • Uterine ultrasound is a noninvasive test that diagnoses conditions such as chromosomal disorders.

    Neurological diagnostic screening tests help physicians determine if a person’s symptoms implicate a neurological disorder. It also gives physicians an idea of what to do next in order to treat a disorder, in case they find one.
