A

State of being aware of surroundings and responding to stimuli only part of the time

31
Q

Syncope

A

Fainting

32
Q

Tonic-Clonic Seizure

A

Type of severe epileptic seizure characterized by a loss of consciousness and convulsions. The seizure alternates between strong continuous muscle spasms (tonic) and rhythmic muscle contraction and relaxation (clonic). It is also called a ‘grand mal seizure.’

33
Q

Tremor

A

Involuntary repetitive alternating movement of a part of the body

34
Q

Unconscious

A

State of being unaware of surroundings, with the inability to respond to stimuli

35
Q

Alzheimer’s Disease

A

Chronic, organic mental disorder consisting of dementia, which is more prevalent in adults after 65 years of age. Involves progressive disorientation, apathy, speech and gait disturbances, and loss of memory. Named for German neurologist Alois Alzheimer

36
Q

Astrocytoma

A

Tumor of the brain or spinal cord composed of astrocytes, one type of neuroglial cells

37
Q

Brain Tumor

A

Intracranial mass, either benign or malignant. A benign tumor of the brain can still be fatal since it will grow and cause pressure on normal brain tissue

38
Q

Cerebellitis

A

Inflammation of the cerebellum

39
Q

Cerebral Aneurysm

A

Localized abnormal dilation of a blood vessel, usually an artery; the result of a congenital defect or weakness in the wall of the vessel. A ruptured aneurysm is a common cause of a hemorrhagic cerebrovascular accident

40
Q

Cerebral Contusion

A

Bruising of the brain from a blow or impact

41
Q

Cerebral Palsy (CP)

A

Brain damage resulting from a defect, trauma, infection, or lack of oxygen before, during, or shortly after birth

42
Q

Cerebrovascular Accident (CVA)

A

Development of an infarct due to loss in the blood supply to an area of the brain. Blood flow can be interrupted by a ruptured blood vessel (hemorrhage), a floating clot (embolus), a stationary clot (thrombosis), or compression. The extent of damage depends on the size and location of the infarct and often includes dysphasia and hemiplegia. Commonly called a ‘stroke.’

43
Q

Concussion

A

Injury to the brain resulting from the brain being shaken inside the skull from a blow or impact. Symptoms vary and may include: headache, blurred vision, nausea or vomiting, dizziness, and balance problems. Also called ‘mild traumatic brain injury (TBI).’

44
Q

Encephalitis

A

Inflammation of the brain

45
Q

Epilepsy

A

Recurrent disorder of the brain in which seizures and loss of consciousness occur as a result of uncontrolled electrical activity of the neurons in the brain

46
Q

Hydrocephalus

A

Accumulation of cerebrospinal fluid within the ventricles of the brain, causing the head to be enlarged. It is treated by creating an artificial shunt for the fluid to leave the brain. If left untreated, it may lead to seizures and mental retardation

47
Q

Migraine

A

Specific type of headache characterized by severe head pain, sensitivity to light, dizziness, and nausea

48
Q

Parkinson’s Disease

A

Chronic disorder of the nervous system with fine tremors, muscular weakness, rigidity, and a shuffling gait. Named for British physician Sir James Parkinson

49
Q

Reye Syndrome

A

Combination of symptoms first recognized by Australian pathologist R. D. K. Reye that includes acute encephalopathy and damage to various organs, especially the liver. This occurs in children under age 15 who have had a viral infection. It is also associated with taking aspirin. For this reason, it’s not recommended for children to use aspirin

50
Q

Transient Ischemic Attack (TIA)

A

Temporary interference with blood supply to the brain, causing neurological symptoms such as dizziness, numbness, and hemiparesis. May eventually lead to a full-blown stroke (cerebrovascular accident)

51
Q

Amyotrophic Lateral Sclerosis (ALS)

A

Disease with muscular weakness and atrophy due to degeneration of motor neurons of the spinal cord. Also called ‘Lou Gehrig’s disease’, after the New York Yankees baseball player who died from the disease

52
Q

Memingocele

A

Congenital condition in which the meninges protrude through an opening in the vertebral column

53
Q

Myelitis

A

Inflammation of the spinal cord

54
Q

Myelomeningocele

A

Congenital condition in which the meninges and spinal cord protrude through an opening in the vertebral column

55
Q

Poliomyelitis

A

Viral inflammation of the gray matter of the spinal cord. Results in varying degrees of paralysis; may be mild and reversible or may be sever and permanent. This disease has been almost eliminated due to the discovery of a vaccine in the 1950s

56
Q

Spina Bifida

A

Congenital defect in the walls of the spinal canal in which the laminae of the vertebra do not meet or close. May result in a meningocele or a myelomeningocele–meninges or the spinal cord being pushed through the opening

57
Q

Spinal Cord Injury (SCI)

A

Damage to the spinal cord as a result of trauma. Spinal cord may be bruised or completely severed

58
Q

Bell’s Palsy

A

One-sided facial paralysis due to inflammation of the facial nerve, probably viral in nature. The patient cannot control salivation, tearing of the eyes, or expression, but most will eventually recover

59
Q

Guillain-Barré Syndrome

A

Disease of the nervous system in which nerves lose their myelin covering. May be caused by an autoimmune reaction. Characterized by loss of sensation and/or muscle control starting in the legs. Symptoms then move toward the trunk and may even result in paralysis of the diaphragm

60
Q

Multiple Sclerosis (MS)

A

Inflammatory disease of the central nervous system in which there is extreme weakness and numbness due to loss of myelin insulation from nerves

61
Q

Myasthenia Gravis

A

Disease with severe muscular weakness and fatigue due to insufficient neurotransmitter at a synapse

62
Q

Neuroma

A

Nerve tumor or tumor of the connective tissue sheath around a nerve

63
Q

Neuropathy

A

General term for disease or damage to a nerve

64
Q

Polyneuritis

A

Inflammation of two or more nerves

65
Q

Radiculitis

A

Inflammation of a nerve root; may be caused by a herniated nucleus pulposus

66
Q

Radiculopathy

A

Refers to the condition that occurs when a herniated nucleus pulposus puts pressure on a nerve root. Symptoms include pain and numbness along the path of the affected nerve

67
Q

Shingles

A

Eruption of painful blisters on the body along a nerve path. Thought to be caused by a Herpes zoster virus infection of the nerve root

68
Q

Epidural Hematoma

A

Mass of blood in the space outside the dura mater of the brain and spinal cord

69
Q

Meningioma

A

A tumor in the meninges

70
Q

Meningitis

A

Inflammation of the meninges around the brain or spinal cord caused by bacterial or viral infection. Symptoms include fever, headache, neck stiffness, lethargy, vomiting, irritability, and photophobia

71
Q

Subdural Hematoma

A

Mass of blood forming beneath the dura mater if the meninges are torn by trauma. May exert fatal pressure on the brain if the hematoma is not drained by surgery
