Nervous System Diagnostic Tests, Procedures, Therapeutics, and Treatments

x-ray of the blood vessels in the brain after a contrast medium (dye) has been injected; used to diagnose a CVA and other injuries and disorders of the brain

record of the electrical impulses of the brain; used to diagnose neurological conditions thar affect brain function and level of consciousness

insertion of a needle between two lumbar vertebrae to remove a sample of cerebrospinal fluid for diagnostic evaluation or therapeutic treatment; commonly used to diagnose meningitis

procedure in which an X-ray of the spinal cord is taken after a contrast agent has been injected into the spine

procedure in which electrodes are placed on the surface of the body over specific nerve areas and a mild electrical impulse is delivered to the areas; used to measure the speed at which electrical impulses travel through a nerve

procedure that uses nuclear medicine and computerized tomography to generate images of the brain; commonly used to diagnose a CVA, Alzheimer’s disease, and epilepsy; also called a brain scan

diagnostic test in which a part of the body is percussed (tapped) with a reflex hammer or other diagnostic stimulus to measure the presence and strength of muscular reflexes (reflex=involuntary reaction to a stimulus)

reflex in which the toes curl upward when the plantar surface (sole) of the foot is stimulated; a positive sign in an adult or in child older than two years of age indicates a disorder in the brain or nervous system (like a brain tumor, meningitis, or multiple sclerosis)

involuntary muscle contractions that occur when the tendons associated with certain areas of the limbs (like the patella or the knee) are percussed with a reflex hammer; they are tested during a standard neurological exam

surgical removal of fatty deposits in one or both carotid arteries (arteries that supply blood to the brain); commonly used to prevent a CVA

surgically implanted device that drains cerebrospinal fluid from the brain ventricles to the abdomen or heart; commonly used to treat hydrocephalus (excessive accumulation of CSF in the ventricles)

surgical removal of part of the skull to gain access to the brain; commonly used to treat swelling in the brain

incision into the skull to gain access to the brain

surgical removal of a herniated (protruding) vertebral disk

surgical removal of the vertebral lamina, or part of the bone that makes up a vertebra in the spine, allowing access to the spinal cord; commonly used to treat a herniated disk

injection of a local or regional anesthetic or anesthesia to prevent pain in an area near a nerve (like Novocain or procain)

surgical repair of a nerve

a form of radiation therapy in which a specially constructed frame is used to focus beams of radiation toward precise areas of the brain; used to treat inoperable tumors

form of psychotherapy or mental health counseling wherein the goal is to help the client to gain an improved awareness of negative thought processes and to adopt strategies for counteracting negative thinking

electrical shock applied to the brain under medical supervision to trigger convulsions; shown to produce changes in brain chemistry that can benefit treatment of severe depression

use of a specialized light source, which replicates natural sunlight, to treat seasonal affective disorder

a form of treatment for psychiatric disorders that emphasizes verbal and nonverbal communication, in a one-on-one setting or in a group environment, to attain a desired response or action

drugs that produce changes in brain chemicals that affect mood and behavior

medication used to reduce feelings of anxiety

medication used to treat depression

antianxiety drug

drug used to balance brain chemical that control emotional states and behaviors associated with certain mental disorders (like bipolar disorder)

medication used to treat psychotic disorders, mainly schizophrenia

drug that increases activity in the nervous system

drug that prevents or relieves convulsions

drug that causes sleep or loss of consciousness

drugs that, in moderate doses, depress the central nervous system, relieve pain, and induce sleep but when taken in excess, produce unconsciousness, stupor, coma, and possibly death.

drug that produces a soothing or tranquilizing effect.
