    Certain tests and procedures are used to detect (find) and diagnose health problems in the brain and spinal cord.

    These and other tests and procedures may be used to detect or diagnose brain and spinal cord late effects:

    • Physical exam and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient's health habits and past illnesses and treatments will also be taken.
    • Neurological exam: A series of questions and tests to check the brain, spinal cord, and nerve function. The exam checks a person's mental status, coordination, and ability to walk normally, and how well the muscles, senses, and reflexes work. This may also be called a neuro exam or a neurologic exam. In some cases, a more detailed exam may be done by a neurologist or neurosurgeon.
    • Neuropsychological assessment: A series of tests to examine the patient's mental processes and behavior. Areas that are checked usually include:
      • Knowing who and where you are and what day it is.
      • Ability to learn and remember new information.
      • Intelligence.
      • Ability to solve problems.
      • Use of oral and written language.
      • Eye-hand coordination.
      • Ability to organize information and tasks.
