117
Modernization contributes to lower status of older adults through:
- Urbanization

Theory
A system of plausible or scientifically acceptable idea intended to explain something or justify a course of action

125
The wear and Tear Theory is influenced by
Influenced by environmental stress, like poverty and poor nutrition
126
Cellular Aging Theory:
Aging that occurs as cells slow their numbers in replications
Each species has a biological clock that determines it's max lifespan and rate at which each organ system will deteriorate
Cells will stop dividing and replicating after a certain number of times
Limits bodies ability to regenerate and respond to injury/stress
127
Immunological Theory:
Rate of aging is controlled by immune system
Defective immune system causes aging
Immune system is important protective function – becomes less efficient in helping body resist pathogens/infections that attack and interfere with normal functioning
128
Immunological Theory may be responsible for
chronic / inflammatory conditions
129
Inflammatory conditions:
immune system attacks own bodies cells or tissues
130
Free Radical Theory (or Oxidative Stress Model):

133
Ultraviolet light from sun is primarily responsible for
wrinkles, dried, and tougher texture or skin
134
Cell replacement in epidermis (outer layer) and dermis thins (second layer) slows, results in
reduced elasticity and fullness of our skin (increased sagging and wrinkling)

Skins blood circulation diminishes, which can
damage effectiveness of temperature-regulating mechanism – increases sensitivity to hot and cold

Why is polypharmacy a concern
When more drugs are being prescribed, especially if they aren't always needed they are more likely to produce drug reactions which can lead to and increase in ER visit
227
Illicit drug use
- can lead to increase in ER visits
| - less common in older adults
228
The rate of drug abuse in older adults is expected to increase how much from 2001 to 2020
by 50%
229
suicide rates are about _____ higher in older adults than in younger groups of the population as a whole
50%
230
Older individuals who are at high risk of suicide
widowed white males above the age of 85 years old who have chronic depression, pain or alcohol use
231
what percent of individuals who committed suicide visits their primary care doctor in the proceeding month
75%
232
Signs and risk factors for suicide in older adults:
lack of physical health, loss of a loved one, depression, financial instability, giving away possessions, statements of frustration of life,
233
Tricyclic Antidepressants (TCAs)
The oldest for of treatment (some of the first medications)
Still around
234
MAOI's, Monoamine Oxidase Inhibitors
- Among the very earliest treatments
- These block an enzyme (Monoamine Oxidase) that then leads to an increase in brain chemicals related to serotonin, epinephrine, dopamine
235
Why aren't MAOI's always prescribed?
Not always prescribed because of the risk of interactions with other medication and even certain foods
236
SSRI's, Selective Serotonin Reuptake Inhibitors
- First line of defense as well as SNRI's (serotonin and norepinephrine reuptake inhibitors)
- The most common medications to treat mental disorders
237
how do SSRI's, Selective Serotonin Reuptake Inhibitors work?
In the brain, neurons are releasing serotonin and norepinephrine naturally; released serotonin into the system, and then sucks some back up to put into the blood stream, but what's happening in people with depression is that we are finding that these reuptake sensors that are sucking up the extra serotonin in the brain cell are overworking, so they are sucking all of the serotonin back in. So instead of leaving some serotonin in the bloodstream, the serotonin is released, and then it all sucked back up
The SSRI works in to interfere with that ^ process to keep it from reup taking ALL the serotonin; inhibits the reuptake so that some of it remains in the bloodstream
238
Electroconvulsive Therapy (ECT)
- Been around a very long time
- Effective in treating very very severe depression
- Using electricity to induce a seizure which can rewire or reset the brain signals; put under anesthesia
- Repeated several times a week for a few weeks
239
Electroconvulsive Therapy (ECT) can lead to what?
memory loss, nausea, can be traumatic
240
Transcranial Magnetic Stimulation
- Only FDA approved to treat depression
- Similar to ECT but instead of using electric shock, it is using a magnet
- Patients are awake, wear a clock cap
- Physician maps out part of the brain that is under excited based on MRI, CT, PET, and use magnet to stimulate that area
241
Non-pharmacological treatments to anxiety and depression
Support groups
Psychotherapy
Exercise
Diet
242
intelligence
The theoretical limit of an individual's performance.
243
intelligence consists of
problem solving, verbal skills, and social competence
244
Fluid intelligence:
- Biologically determined
- Abstract reasoning
- mathematical reasoning
- spatial relationships
- perceptual speed
- Ability to reason and think flexibly
245
Crystallized intelligence:
- knowledge and abilities acquired
- Verbal meaning
- social judgement
- number skills
- verbal memory
246
older adults decline in _____ and stay stable in _____ and the speed of _____ deteriorates*
fluid intelligence; crystalized intelligence; cognition processing
247
_____ and _____ are processes that must be considered together.
learning and memory
248
Working (primary) Memory
- Temporary stage of holding, processing, and organizing information
- Decides what should be stored or ignored
249
Secondary (long term) memory:
- Lasting or permanent storage or information
- Where things go that you can recall later
- You have to be encoding this and to do this you must engage in it
250
Sensory Memory
- Memories generated or recalled via touch, smell, taste, sight or sound
- Based on receiving memory from longterm storage
- Memories may be activated or easier to remember when a sound or smell is present that was also present at the time you learned something
251
Learning
Info must be rehearsed or processed to be retrieved later
Info is retrieved through recall (free or cued) and recognition
252
Learning occurs when
newly acquired information become encoded or stored in secondary memory
253
Many factors can impact learning (and appear to impact memory)
1. External factors (environment factors like poor lighting)
2. Psychological factors: anxiety or expectations
3. Other: educational level, language proficiency, slowing of CNS
254
Executive functioning
the brains ability to organize our learning and efficiently use stored information in our secondary memory to plan, make decisions, and shift from one task to another
- The CEO of the brain
255
what can impair executive functioning
Dementia and brain injury
256
Impairments impact what
every part of daily live including ADLs, employment capability, and relationships/roles
257
Theories of Loss: Disuse theory:
- Use it or lose it
| - Info can fade away if not used
258
Theories of Loss: Interference Theory
Poor retrieval due to:
- Distraction during the learning phase
- Retroactive interference (new memories disrupt old memories)
Ex. Learning french may impact our memory of previously learning spanish
259
Theories of Loss: Spatial Theory
Recognizing where objects are in relation to each other
"you are here" maps study
260
Theories of Loss: General Slowing Hypothesis
General Slowing Hypothesis
Aging causes a slowing of information processing in the nervous system
261
Dementia
An umbrella terms that describes a group a symptoms associated with the decline in memory or other thinking skills severs enough to reduce the persons ability to do everyday activities
262
Two of the following must be significantly impaired to be considered dementia
```
Memory
Communication/language
Ability to focus and pay attention
Reasoning or judgement on things
Visual perception
```
263
who is at higher risk for dementia
oldest of the old
264
Reversible dementia
```
Depression
Medication side effects
Excess use of alcohol
Thyroid problems
Vitamin deficiencies
```
265
Irreversible dementia
```
Alzheimer's disease (typical and early onset)
Vascular dementia
Creutzfeldt-Jakob disease
Dementia with Lewy Bodies
Huntington's disease
More
```
266
What consumers 50-80% of all dementias
Alzheimers disease
267
6th leading cause of death for elders
alzheimer's disease
268
How many people does alzheimer's disease effect
1 out of every 8 americans over the age of 65
269
how often is someone diagnosed with alzheimer's
every 68 seconds
270
What is the life expectancy once diagnosed with alzheimer's disease
Most people survive 4-8 years after diagnosis
Few live as long as 20 years
271
