The Neurologist’s Guide to Diagnosing Brain Disorders


Neurologists diagnose brain disorders by taking a patient’s medical history, conducting a physical examination and performing testing. They examine patients for signs of brain injury, such as concussion, or for seizures or epilepsy.

Physical Examination

A physical examination, sometimes called a neurological exam, is a test that examines one or more aspects of your nervous system. It helps confirm or rule out disorders affecting your brain, nerves and spinal cord.

The exam often starts with an interview about your symptoms and how they affect you. It may also include a physical exam, which tests movement of your face, eyes and tongue.

Laboratory Tests

Several tests can be performed to help your neurologist make an accurate diagnosis of brain disorders. These include imaging scans and laboratory testing.

One test is called a spinal tap (lumbar puncture). It involves inserting a needle into the spinal canal to collect a sample of cerebrospinal fluid, a clear fluid that bathes the brain and Result spinal cord. It is analyzed for color, blood cell counts, protein, glucose and other substances.

Imaging Tests

There are a variety of imaging tests used to look at the brain and nervous system. They can help diagnose conditions such as stroke, tumors and vascular dementia.

These include CT scans, MRI (magnetic resonance imaging), PET scans and spinal taps.

Neuropsychological Tests

Neuropsychological tests, also called cognitive testing, are used to help doctors diagnose brain disorders. These tests are not painful or invasive and do not require you to be hooked up to tubes.

They measure thinking and behavior skills such as memory, language, processing speed and executive function. They also assess mood and personality. Tests are usually conducted with a trained technician.

Other types of blood tests are often ordered to evaluate the levels of therapeutic drugs used to treat brain disorders or to identify medical conditions adversely affecting the neurological system. They can also be used to diagnose dementia and rule out other conditions that may cause the symptoms.

Genetic Tests

Genetic testing is used to detect changes in genes that may affect your health. These tests can identify specific diseases or conditions and help doctors make better treatment decisions.

For example, genetic tests can help diagnose epilepsy and guide the choice of anti-seizure medications. They can also help families understand their risk of having a child with a certain condition, and may inform reproductive choices.
