A

Excessive accumulation of cerebrospinal fluid (CSF) within the ventricles of the brain that is most common in neonates, but can also occur in adults as a result of injury or disease; if left untreated, causes an enlarged head and cognitive decline

Q

neruoblastoma

A

malignant tumor composed mainly of cells resembling neuroblasts that occurs most commonly in infants and children

27
Q

neurosis

A

Nonpsychotic mental illness that triggers feelings of distress and anxiety and impairs normal behavior

28
Q

palsy

A

partial or complete loss of motor function; also called paralysis

29
Q

Bellpalsy

A

facial paralysis on one side of the face as a result of inflammation of a facial nerve

30
Q

cerebralpalsy

A

bilateral, symmetrical, nonprogessive motor dysfunction and partial paralysis, which is usually caused by damage to the cerebrum during gestation or birth trauma but can also be hereditary

31
Q

pralysis

A

loss of muscle function, loss of sensation, or both as a result of spinal cord injury

32
Q

parkinson disease

A

progressive neurological disorder caused by a neurotransmitter deficiency (dopamine) that affects the portion of the brain responsible for controlling movement and results in hand tremors; uncontrollable head nodding; shuffling gait; and difficulty talking, swallowing, or completing simple tasks

33
Q

poliomyelitis

A

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

34
Q

sciatica

A

severe pain in the leg along the course of the sciatic nerve, which travels from the hip to the hip

35
Q

shingles

A

chronic viral disease in which painful blisters appear on the skin along the course of a peripheral nerve that is caused by inflammation secondary to herpes zoster virus, the same virus that causes chickenpox; also called herpes zoster

36
Q

spina bifida

A

congenital neural tube defect characterized by incomplete closure of the spinal canal through which the spinal cord and meninges may or may not protrude

37
Q

spina bifida occulta

A

most common and least severe form of spina bifida without protrusion of the spinal cord or meninges

38
Q

spina befida cystica

A

more severe type of spina bifida that involves protrusion of the meninges (meningocele), spinal cord (myelocele), or both meningomyelocele

39
Q

stroke

A

inadequate supply of blood and oxygen to the brain due to a clot or ruptured blood vessel (hemorrhage), which allows brain tissue to die and becomes a medical emergency; also called cerebrovascular accident (CVA)

40
Q

Cerebrospinal fluid (CSF) analysis

A

laboratory test that examines a sample of CSF obtained from a lumbar puncture, which is analyzed for the presence of blood, bacteria, and malignant cells as well as for the amount fo protein and glucose present

41
Q

electroencephalography (ECG)

A

electrodes are placed on the scalp to record electrical activity within the brain; used to evaluate seizure and sleep disorders and periods of unconsciousness, monitor brain surgeries, and determine whether a person is in a coma or brain dead

42
Q

lumbar puncture (LP)

A

insertion of a needle into the subarachnoid space of the spinal column to withdraw a sample of CSF used for biochemical, microbiological, and cytological laboratory analysis; also called spinal tap or spinal puncture

43
Q

craniotomy

A

surgical procedure that creates an opening in the skull to gain access to the brain during neurosurgical procedures

44
Q

thalamotomy

A

partial destruction of the thalamus to treat psychosis or intractable pain

45
Q

trephination

A

excision of a circular disk of bone using a specialized saw called a trephine to reveal brain tissue during neurosurgery, or to relieve intracranial pressure (ICP)

46
Q

anesthetics

A

produce partial or complete loss of sensation with or without loss of consciousness

47
Q

general anesthetics

A

produce complete loss of feeling with loss of consciousness
