Exam 2: Neurology Flashcards
Degenerative disorders are progressive in nature, we must focus on…
symptom management, promoting independence, acceptance of loss of function
multi interdisciplinary approach
e.g. of degenerative disorders
dementias
Parkinson disease
MS
ALS
__________ progressive neurodegenerative disease characterized by a cognitive decline that causes impairment in daily functioning
Dementia
What are the subtypes of dementias
- Alzheimer’s (most popular)
- Vascular dementia
- Lewy body dementia
- Frontotemporal dementia (least popular)
What are risk factors of dementia
age > 65 years old
female gender – females live longer than men
Dementia is NOT a normal physiologic change of aging
Alzheimer’s will cause
memory loss, confusion, and cognitive declines
What is the patho of alzheimer’s
buildup of beta-amyloid plaques and TAU (neurofibrillary) tangles in the brain, which disrupts communication between neurons and leads to their eventual death
What are the early symptoms of alzheimer’s
difficulty remembering recent events, followed by language issues, disorientation, mood changes, and eventually the inability to perform daily tasks –> no cure
Vascular dementia patho
occurs when the brain’s blood supply is reduced due to stroke, small vessel disease, or other conditions affecting blood vessels
Vascular dementia leads to
cognitive decline because brain cells are deprived of oxygen and nutrients
What are symptoms of vascular dementia
difficulties with problem-solving, focus, organization, and slower thinking
What is the difference with vascular vs alzheimers dementia
Unlike alzheimer’s, memory loss may not be the initial symptom
With vascular dementia the progression can be
stepwise, worsening after each stroke or vascular event
What is LBD caused by
accumulation of abnormal protein deposits called Lewy bodies in the brain
What will LBD affect
memory, movement, and mental abilities
People with LBD often experience
visual hallucinations, fluctuations in cognitive abilities, Parkinsonism (stiffness, tremors, and slow movement), and sleep disturbances
T/F LBD has symptoms like Alzheimer’s and is often misdiagnosed
True
FTD is a group of disorders caused by damage to
frontal and temporal lobes of the brain
–personality, behavior, and language
FTD results in
personality changes, emotional problems, and difficulty with speech (aphasia)
FTD typically occurs in which age group
younger 50s or 60s
Unlike Alzheimer’s, FTD memory is usually
preserved in the early stages, but people may show socially inappropriate behaviors, poor decision making, or lack of empathy
What are diagnostic exams for dementia
CT/MRI, LP, biopsy post mortem most definitive
What MRI finding’s do we see with alzheimer’s
loss in volume of the brain but hypertrophy of the ventricles
Early stage of AD
independent in ADL’s
may deny presence of symptoms
forgets names; misplaces household items
has short term memory loss, difficulty recalling new info
shows changes in personality and behavior subtly
loses initiative and is less engaged in social relationships
has mild impaired cognition and problems with judgement
unable to travel alone to new destinations
often has decreased sense of smell
Mild stages of AD
has impairment of all cognitive functions
demonstrates problems with handling or is unable to handle money and finances
is possibly depressed or agitated
no longer AAOx3/4
has visuospatial deficits –> gets lost
has speech and language deficits: less talkative, decreased use of vocabulary, increasingly non fluent, and aphasic
incontinent of urine and stool
psychotic behaviors
wandering, trouble sleeping
Late stages of AD
completely incapacitated; BR
totally dependent ADLs
has loss of mobility and verbal skills
possibly has seizures and tremors
has agnosia
The priority collaborative problems for patients with AD include
memory and cognition
injury
elder abuse
symptom management at end of life
What is the priority for inter-professional care with AD
safety
prevent injury or accidents; prevent elder abuse
Pharmacological therapy for AD
AchE inhibitors: donepezil, galantamine, rivastigmine
NMDA antagonist: memantine
Antidepressants: SSRI
Psychotropic drugs: chemical restraints
Ginkgo, vitamin E
How do we help cope with restlessness and wandering
ensuring the patient is wearing identification bracelet
registering the patient for safe return program
providing frequent walk and structured activities
Interventions to mitigate risk for injury with AD
ensuring safety by removing all potentially dangerous objects, particularly in case seizures occur
T/F it’s important to make caregivers and family aware of their own health and stress resulting from new responsibility in AD care
True
Patho of Parkinson’s
loss of dopamine resulting in loss of tone, loss of inhibition of gross movement
atrophy and neuronal loss
Majority of parkinsons is _______
primary (idiopathic)
secondary is from something such as tumor or meds
Risk factors of Parkinson’s
genetic and environmental factors, affects more men over 40
PD is separated into stages…
Stage 1 is mild progressing to stage 5 which is completely dependent
TRAP for PD
tremor
rigidity
akinesia/bradykinesia
postural instability (late)
