broad term that refers to cognitive deficit, including memory impairment

Answer 12

inability to learn and process written language, despite adequate intelligence, sensory ability, and exposure

Answer 13

Autoimmune condition that causes acute inflammation of the peripheral nerves damaging their myelin sheaths, resulting in decreased nerve impulses, loss of reflex response, and sudden muscle weakness - infective/idiopathic polyneuritis

Answer 14

Acute inflammatory eruption of highly painful vesicles on the trunk of the body or, occasionally, the face that is caused by the same virus that causes chickenpox - shingles

Answer 15

CNS disorder characterized by quick, involuntary movements, speech disturbances, and mental deterioration - neurodegenerative genetic disorder

Answer 16

Accumulation of fluid in the ventricles of the brain, causing increased intracranial pressure (ICP), thinning of brain tissue, and separation of cranial bones

Answer 17

abnormal inactivity or lack of response to normal stimuli

Answer 18

Chronic, progressive disorder in which a loss of neurotransmitter receptors produces increasingly severe muscle weakness

Answer 19

Congenital deformity of the neural tube (embryonic structure that becomes the fetal brain and spinal cord), which fails to close during fetal development - neural tube defect

Answer 20

form of spina bifida in which the spinal cord develops properly but the meninges protrude through the spine

Answer 21

most severe form of spina bifida in which the spinal cord and meninges protrude through the spine

Answer 22

form of spina bifida in which one or more vertebrae are malformed, and the spinal cord is covered with a layer of skin

Answer 23

paralysis, usually partial, and commonly characterized by weakness and shaking or uncontrolled tremor

Answer 24

facial paralysis caused by a functional disorder of the seventh cranial nerve - facial nerve palsy

Answer 25

type of paralysis that affects movement and muscle coordination and may affect gross and fine motor skills

Answer 26

loss of voluntary motion in one or more muscle groups with or without sensation

Answer 27

sensation of numbness, prickling, tingling, or heightened sensitivity

Answer 28

Degenerative disorder in which the progressive loss of brain cells leads to impairment in motor function, including tremors, muscular rigidity, and a slowing of movement - paralysis agitans - shaking palsy

Answer 29

Inflammation of the gray matter of the spinal cord caused by a virus, commonly resulting in spinal and muscle deformity and paralysis

Answer 30

Disorder affecting one or more nerves at the location where the nerve root exits the spine and commonly the result of a herniated or compressed disk, degenerative changes, arthritis, or bone spurs - radiculitis

Answer 31

Potentially fatal syndrome that commonly causes brain swelling and liver damage and is characterized by confusion, hyperventilation, violent behavior, seizures, and possibly coma - acute noninflammatory encephalopathy - fatty degenerative liver failure

Answer 32

brief loss of consciousness and posture caused by a temporary decrease of blood flow to the brain - fainting

Answer 33

recording of electrical activity in the brain, whose cells emit distinct patterns of rhythmic electrical impulses

Answer 34

Recording of electrical signals (action potentials) that occur in a muscle when it is at rest and during contraction to assess muscular disease or nerve damage

Answer 35

Needle puncture of the spinal cavity to extract spinal fluid for diagnostic purposes, introduce anesthetic agents into the spinal canal, or remove fluid to allow other fluids (such as radiopaque substances) to be injected - spinal puncture - spinal tap

Answer 36

test that measures the speed at which impulses travel through a nervec

Answer 37

Laboratory test to examine a sample of the fluid surrounding the brain and spinal cord that helps diagnose disorders of the central nervous system, including viral and bacterial infections, tumors, and hemorrhage

Answer 38

Radiographic image of the interior of a vessel in combination with a CT scan to produce high-resolution, three-dimensional images of blood vessels

Answer 39

CT scan of the lumbar region after injection of a contrast medium to detect problems with the spine and spinal nerve roots

Answer 40

Ultrasound technique used to study intracranial structures of the brain and diagnose conditions that cause a shift in the midline structures of the brain

Answer 41

Noninvasive neuroimaging technique to pinpoint the specific location where seizure activity originates and enable custom surgical treatment for tumor and epileptic tissue resection - magnetoencephalography

Answer 42

Radiographic examination to detect pathology of the spinal cord, including the location of a spinal cord injury, cysts, and tumors following injection of a contrast medium

Answer 43

Computed tomography that records the positrons (positively charged particles) emitted from a radiopharmaceutical and produces a cross-sectional image of metabolic activity of body tissues to determine the presence of disease

Answer 44

technique that exposes abnormal tissue to extreme cold to destroy it

Answer 45

Partial destruction of the thalamus to treat intractable pain; involuntary movements, including tremors in Parkinson disease; or emotional disturbances

Answer 46

transection of a nerve tract in the brainstem or spinal cord

Answer 47

technique that cuts a circular opening into the skull to reveal brain tissue and decrease intracranial pressure
