Aura definition - correct answer -can manifest as perception of a
strange light, unpleasant smell, confusing thoughts (can indicate a
seizure is about to occur
Myoclonus definition - correct answer -brief muscle twitching
postictal period - correct answer -post-seizure
ictal period - correct answer -phase during seizure
interictal period - correct answer -normal brain activity between
seizures
, Page | 2
pathophysiology of cataracts - correct answer -As a
consequence of normal aging, the lenses in the eyes develop
excessive layers of epithelium. The epithelial cells lose the ability
to degenerate as new layers of cells proliferate and accumulate.
The increased thickness of the lens makes it less able to
accommodate. Also, the water solubility of the lens diminishes,
making it more inflexible
risk factors for glaucoma - correct answer -age (>40), ethnicity
(Asian descent), history of migraine headaches, cardiovascular
disease, medications, systemic hypotension, specific drugs, such
as sympathomimetics, anticholinergics, selective serotonin
receptor inhibitor antidepressants, sulfonamides, cocaine, and
Botox
pathophysiology of Alzheimer's - correct answer -Progressive
neurological degenerative disease of the brain is characterized by
significant changes in brain tissue. There is an accumulation of
neurofibrillary tangles, senile plaques (also called beta-amyloid
plaques), cerebrocortical atrophy of the brain, and acetyl choline
deficiency (important for memory).
tau protein role in Alzheimer's - correct answer -they are
changed chemically and become neurofibrillary tangles. When
this happens, the microtubules disintegrate, collapsing the
, Page | 3
neuron's transport system, resulting in malfunctions in
communication between neurons. leads to death of brain cells.
The tangles and plaques eventually build up and take over normal
neural tissue in the brain.
Alzheimer's risk factors - correct answer -age (>65), family
history, females, heart disease, lack of exercise, smoking, HTN,
hyperlipidemia, diabetes
Dementia- etiology - correct answer -Alzheimer's disease,
vascular dementia, Lewy body dementia (LBD)
Dementia- clinical manifestations - correct answer -Amnesia
(commonly the first symptom experienced), Anomia (forgetting the
names of things and people), Apraxia (difficulty in performing
familiar tasks, occurs. The individual may forget how to get
dressed properly or forget how to prepare a meal), Agnosia
(forgetting the purpose of familiar items), sun downing (acute
confusion, disorientation, hallucinations, and mood swings during
late day into night, often occurs), anxiety, apathy, aphasia
Autism spectrum disorder clinical manifestations - correct
answer -Demonstrate delays in social interaction,
