Did you know that years ago there
was only way to absolutely be sure if someone has a neurological disorder. An autopsy
would need to be performed. Nowadays there are many diagnostic tools medical
professionals can use to rule out the presence of neurological disorder. Most
tools focus on diagnostic imaging. Significant changes have been made in this
area of diagnosis. However, advancements have also been made in the use of
screening tests and other diagnostic tests.
Common Neurological Screening Tests
Laboratory tests – these involve the
use of collecting blood, urine, or other bodily fluid samples to diagnose
disease. Medical professionals will order a laboratory test to get general
information or identify specific concerns. Take for example a brain or spinal
cord infection. Blood tests can detect the microorganism causing that
infection. Blood tests can also confirm for the presence of toxins directly
affecting the nervous system or identify if hemorrhaging is a factor.
Genetic tests – recall that some
neurological disorders are of genetic origin. This is why genetic testing can
identify neurological disorders in utero. Consider a pregnant woman. She can
take a genetic test to determine whether her growing child is at risk for
developing a neurological disorder. For example, one procedure is called an amniocentesis. A sample is taken from the
amniotic fluid in the womb. It is tested for possible markers that correlate to
genetic defects the fetus may be at risk for developing.
