It may also test mental status, mood, and behavior. Depending on the type of test, results may be immediate or may take time to process.Ī neurological examination assesses motor and sensory skills, hearing and speech, vision, coordination, and balance. Some procedures are performed in specialized settings to determine particular disorders or abnormalities.
Many tests can be performed in a physician’s office or at an outpatient testing facility, with little if any risk to the person. Researchers and physicians use a variety of diagnostic imaging techniques and chemical and metabolic tests to detect, manage, and treat neurological disease. Scientists continue to improve these methods to provide more detailed diagnostic information. Specialized imaging methods can visualize changes in brain activity or the amounts of particular brain chemicals. Improved imaging techniques provide high-resolution images that allow physicians to view the structure of the brain. Much has been learned from sequencing the human genome (the complete set of a person’s genes) and developing new technologies that detect genetic mutations. Perhaps the most significant changes during the past 10 years have occurred in genetic testing and diagnostic imaging. Doctors now have powerful and accurate tools to better diagnose disease and to test how well a particular therapy may be working. Today, new instruments and techniques allow scientists to assess the living brain and monitor nervous system activity as it occurs. A century ago, the only way to make a definite diagnosis for many neurological disorders was to perform an autopsy after someone had died. What are some diagnostic tests used to diagnose neurological disorders?ĭiagnostic tests and procedures are vital tools that help physicians confirm or rule out a neurological disorder or other medical condition. What are some of the more common screening tests?
