Unit 3 Alzheimer's Disease
Terms in this set (17)
Approximately how many individuals in the United States are affected by Alzheimer's Disease?
Which are contributing factors to the development of dementia?
Age over 65
Most cases of Alzheimer's disease develop in people who are more than 65 years old.
Parent with dementia
A family history of Alzheimer's disease has been linked to increased likelihood of developing the disease.
Poor health maintenance
Poor health maintenance habits can lead to chronic disease states, which has been linked to increased likelihood of developing Alzheimer's disease.
Which individual is at the greatest risk for developing Alzheimer's disease?
An 82-year-old Hispanic female
Which describe the pathophysiology of Alzheimer's disease?
Dilation of ventricles in the brain
Ventricles of the brain dilate as the cerebral cortex atrophies.
Formation of plaques in the cerebral cortex
Amyloid plaques form in the cerebral cortex of the brain, disrupting transport pathways.
Loss of volume of brain tissue as neurons deteriorate and die
Loss of brain volume as neurons die, which contributes to the cognitive and functional deterioration of the brain.
In early Alzheimer's disease, where in the brain do amyloid plaques form?
The cerebral cortex
Formation of plaques in the cerebral cortex results in a loss of neurons' ability to transmit impulses and affects cognitive thought.
A women who suffers from moderate Alzheimer's disease is not able to understand instructions to put on her shoes. She asks "What does that mean?" Which symptom of dementia does this describe?
Dysphasia is difficulty understanding language and communication. Failure to identify common items is seen in moderate Alzheimer's disease.
The inability to make purposeful movements describes which manifestation of Alzheimer's disease?
Apraxia describes the inability to make purposeful movements and lack of control of body movements.
Which scenarios describe dysgraphia?
Unable to recognize words in books
Not being able to understand words is characteristic of dysgraphia.
Trying to write a note and only being able to draw lines
Inability to communicate through writing describes dysgraphia.
Not being able to read a note a person wrote a day ago
Dysgraphia refers to an inability to understand written words or an inability to write to express thoughts.
Which are accurate statements about Alzheimer's disease?
Alzheimer's disease is always fatal.
There is no cure for Alzheimer's disease. It is progressive and fatal.
The incidence of Alzheimer's is increasing.
As the overall population becomes older, people are living longer, and are more likely to develop Alzheimer's disease with advanced age.
There are identified risk factors for Alzheimer's disease.
Alzheimer's disease is associated with certain risk factors, which have been shown to increase likelihood of contracting the disease.
Which diseases are associated with an increased risk of developing Alzheimer's disease?
Diabetes can contribute to the development of Alzheimer's disease by affecting the body's ability to break down amyloid proteins, which form plaques in the cerebral cortex.
Cardiovascular disease is associated with Alzheimer's disease and dementia in that the narrowed vessels reduce the supply of oxygen to the brain, which leads to loss of brain volume and deterioration.
Which external factor is a contributing factor to the development of Alzheimer's disease?
Head injury has been shown to increase the risk of Alzheimer's disease. Professional football players and military veterans who have suffered head trauma are at risk of developing the condition.
Which describes the normal function of tau proteins?
To keep the transport pathways in neurons parallel
Tau proteins keep neurotransmitter pathways straight. When tau proteins collapse into twisted strands, neurofibrillary tangles occur, which inhibits normal neuron transport.
Which describes the mechanism by which the brain shrinks in dementia?
Widespread death of neurons
Widespread death of neurons causes the brain to shrink dramatically in size and volume, which affects overall brain function.
Which statements about neuron transmission are true?
Tau keeps transport pathways parallel.
Pathways must be parallel for effective transport to take place.
If tau protein tangles, transport is not possible.
When tau protein tangles and disintegrates, transport is not possible.
Without the ability to transport, neurons can die.
Neurons lose the ability to transport die, which causes widespread loss of brain function.
Plaques that form in the cerebral cortex interfere with normal transmission.
Transport is not possible across plaques, and widespread death of neurons occurs.
An 84-year-old woman has been diagnosed with Alzheimer's disease. She has begun playing with dolls, and cries if she does not get what she wants. She likes coloring books and often asks for her mother. Which describes the process happening?
Retrogenesis is a reversal of developmental stages, in which a person with Alzheimer's disease will experience a reversal in developmental stages, and develop child-like behaviors.
Which are common manifestations seen in moderate Alzheimer's disease where retrogenesis is present?
Requires assistance with bathing
Which are accurate statements about behavioral changes in Alzheimer's disease?
Mood swings are an early symptom.
Paranoia and hallucinations may occur in moderate stage.
It is often a family member or support person who is best able to describe behavioral changes.
