Most common
permanently disabling
birth defect in the U.S. is?

Acetylcholine drugs are used to improve cognition. Their effects are not permanent
72
CVA/stroke
occurs when blood flow to a
part of the brain is interrupted or
reduced, depriving brain tissue of
oxygen and nutrients. When brain cells
are deprived of oxygen, they begin to die
within minutes, potentially leading to
long-term neurological impairments or
death if not treated swiftly
73
What is the major cause of serious, long-
term disabilities in adults
CVA
74
Ischemic Stroke
This is the most
common type, accounting for about
87% of all strokes. It occurs when a
blood clot blocks or narrows an
artery leading to the brain, often
due to atherosclerosis (buildup of
plaque in the arteries)
75
Hemorrhagic Stroke
This type results from hemorrhage or rupture of a brain vessel, which causes
leakage of blood into the brain
tissue, the ventricles, or the space
between the brain and skull
76
Transient Ischemic Attack
(TIA)
Often called a "mini-stroke," a
TIA occurs when blood flow to the
brain is briefly interrupted. While
symptoms may resolve within
minutes, a TIA is a serious warning
sign of a potential future stroke.
Followed by a complete clinical
recovery
77
Symptoms of a stroke
* Weakness or numbness, often on one
side of the body (face, arm, or leg)
* Difficulty speaking or understanding
speech
* Vision problems in one or both eyes
* Severe headache, sometimes
accompanied by vomiting or dizziness
* Difficulty with balance or coordination
78
What does FAST stand for?
Face drooping
Arm weakness
Speech difficulties
Time to call
79
The side of the face and body affected by stroke is opposite that of the brain injury, true or false?
True, because the sensory and motor neurons cross as they go to/from the cerebral cortex
80
RIGHT SIDE BRAIN DAMAGE
- Paralyzed left side
- Spatial or perceptual deficits
- Impaired thought process
- Quick, impulsive behavior
- Patient cannot use a mirror
- Difficulty preforming tasks: ex. Toothbrushing

82
Treatment for ischemic stroke is?
Treatment typically includes clot-busting
drugs (thrombolytics) like tissue plasminogen activator (tPA),
which is most effective if given within the first 3-4.5 hours.
83
Treatment for hemorrhagic stroke is?
Treatment may involve surgery to
repair blood vessel damage, reduce pressure in the brain, or
stop bleeding.
84
Long-term management after stroke make include?
Rehabilitations and lifestyle modifications
85
After a CVA patients must wait 6 months for elective treatment, true or false?
True
86
Using the minimum amount of EPI in anesthetic for CVA patients is important because?
It can increase bleeding
87
Amyotrophic Lateral Sclerosis (ALS) aka Lou Gehrig's disease
a progressive neurodegenerative
disorder that affects motor neurons in the brain and spinal cord. ALS
leads to muscle weakness, loss of voluntary movement, and ultimately
paralysis, as the brain loses its ability to initiate and control muscle
function. Although cognitive functions are typically preserved, ALS
severely impacts a person’s physical abilities over time
88
“Progressive Degeneration” refers to?
cell death of the motor neurons
(debilitates the brains ability to initiate and control muscle movements
89
Caucasian men are at a higher risk than women of any other ethnicity for ALS, true or false?
True
90
How does ALS work?
ALS specifically targets motor neurons, which are nerve cells responsible
for controlling muscle movement. As these neurons degenerate and die,
they stop sending signals to muscles, leading to atrophy (muscle wasting)
and weakness.
91
Types of ALS are?
Sporadic or familial
92
Sporadic ALS
The most common form, accounting
for 90-95% of cases. It occurs randomly without a clear family history
93
Familial ALS (FALS)
Occurs in about 5-10% of cases and is
inherited genetically. Several gene mutations, including those in the SOD1 and C9orf72 genes, are associated with
familial ALS
94
50% of familial ALS
individuals can produce
offspring with the gene
mutation and cause the
disease, true or false?
True
95
Sporadic ALS usually occurs in people 50-65 years of age, true or false?
True
96
Stages of ALS
Early, middle, late, end
97
Treatment to slow progression of ALS
Riluzole (Rilutek) is currently the
ONLY FDA approved medication
to slow the progression of ALS
98
Multiple Sclerosis
chronic autoimmune
disease that affects the central
nervous system, particularly the
brain and spinal cord. In MS, the
immune system mistakenly attacks
the protective sheath (myelin)
covering nerve fibers, causing
inflammation and damage that
disrupts communication between
the brain and the rest of the body
99
When does multiple sclerosis usually begin?
Early childhood with a mean age of 33
100
Who is primarily affected by multiple sclerosis?
Caucasian females
101
Multiple sclerosis is more common in what type of climate?
Cold climates with higher altitudes
102
Relapsing-Remitting MS (RRMS)
The most common form,
characterized by episodes of new or worsening symptoms
(relapses) followed by periods of partial or complete recovery
(remissions)
103
Primary-Progressive MS (PPMS)
Marked by a steady worsening of
symptoms without distinct relapses or remissions
104
Secondary-Progressive MS (SPMS)
Often follows RRMS, with
gradual progression over time and fewer or no relapses
105
Types of multiple sclerosis
Relapsing-remitting, primary-progressive, secondary progressive
106
Etiology of MS
Exact cause unknown, thought to be genetic and environment factors (smoking, obesity, location), or infections and immune system dysfunction (Epstein-Barr virus)
107
LA-DRB1 gene on
chromosome 6, have been strongly associated with what?
MS
108
Oral symptoms of MS
- TMJ pain
- Trigeminal neuralgia
- Loses muscle coordination
- Tongue and facial muscles interfere with
self-cleansing mechanisms in oral cavity
- Oral hygiene becomes difficult
- Facial pain
- Xerostomia
- Gingival Enlargement
109
Parkinsons disease
Chronic progressive
neurodegenerative disorder
primarily affecting movement. It
occurs due to the gradual loss of
dopamine-producing neurons in
the substantia nigra, a part of the
brain that regulates movement
110
Etiology of Parkinsons
No cause for the
destruction of dopamine-
producing neurons
111
One of the most common brain
disease (second to Alzheimer's
Disease) is?
Parkinsons
112
600,000 people in the US
diagnosed each year with what?
Parkinsons
113
Parkinsons has a peak onset age of what with a higher incidence in men than women?
50-60 years
114
Motor Symptoms of Parkinsons
Tremors (usually starting in
one hand), muscle rigidity, bradykinesia
(slowed movement), and postural instability
115
Non-Motor Symptoms of Parkinsons
These can include depression, cognitive decline, sleep disturbances, and autonomic dysfunction, such as blood pressure fluctuations or constipation
116
How many stages are there of Parkinsons
5
117
Medications for Parkinsons
Levodopa is the primary treatment, as it
is converted to dopamine in the brain, alleviating motor symptoms. Other medications, such as dopamine agonists, MAO-B inhibitors, an
118
Deep Brain Stimulation (DBS) for Parkinsons is what?
A surgical option for
patients who do not respond to medication. DBS involves implanting electrodes that provide electrical impulses to targeted brain areas, reducing motor symptoms
119
"Masked face" is a common symptom of?
Parkinsons
120
What are special considerations for Parkinsons?
- Safety
- Orthostatic hypotension
- Xerostomia
