Which of the following best describes how sleep patterns change during late adulthood?
People sleep less deeply than they did when they were younger
. … When the pace of change is slow, young people learn mostly from older adults and the status of older adults is high.
What are some structural age-related changes that occur in neurons? – Structural changes include
decreases in the size and number of dendrites
. – The development of tangles in the fibers that make up the axon. – Increases in the deposit of certain proteins.
Which of the following is not a change in sleep patterns with increasing age in adulthood quizlet?
which of the following is NOT a change in sleep patterns with increasing age in adulthood? True:
insomnia
increases with age.
Which of the following best describes the conclusions about changes in average IQ with age drawn from cross sectional versus longitudinal studies?
Which of the following best describes the conclusions about changes in average IQ with age drawn from cross-sectional versus longitudinal studies?
Cross-sectional findings point to a decline in IQ beginning at about age 35
, while longitudinal data point to much longer maintenance of IQ.
How does the brain change in late adulthood quizlet?
in late adulthood the
brain actually shrinks and total brain mass declines
. declines also take place in certain neurotransmitters, such as acetylcholine and dopamine. the earliest symptom of alzheimer's disease is a loss of memory for recent events and familiar names and tasks.
How much sleep do 100 year olds need?
Some sleep experts suggest that seniors actually need less sleep than other age groups. Most people need
between 7 and 9 hours
of sleep whereas many seniors can get away with 7.5 hours. Other experts believe that seniors need just as much sleep as the rest of the population.
What is the most common chronic disorder in late adulthood?
The two most common chronic conditions in the elderly are
high blood pressure and arthritis
, with diabetes, coronary heart disease, and cancer also being reported at high rates among the elderly population.
These aging-related structural changes to neurons include
a decrease in the number and length of dendrites, loss of dendritic spines
, a decrease in the number of axons, an increase in axons with segmental demyelination, and a significant loss of synapses.
The brain shrinks with increasing age and there are changes at all levels from molecules to morphology. Incidence of
stroke, white matter lesions
, and dementia also rise with age, as does level of memory impairment and there are changes in levels of neurotransmitters and hormones.
Which region of the brain is implicated in emotional processing quizlet?
The prefrontal cortex
includes three areas of relevance to emotion: the orbitofrontal region, the dorsolateral prefrontal region, and the medial prefrontal region.
At what age do we see the most dramatic cognitive changes occurring?
“Cognitive decline may begin after midlife, but most often occurs at higher ages
(70 or higher)
.” (Aartsen, et al., 2002) “… relatively little decline in performance occurs until people are about 50 years old.” (Albert & Heaton, 1988). “…
What are three cognitive and emotional changes that occur within the elderly?
Slower inductive reasoning / slower problem solving
.
Diminished spatial orientation
.
Declines in perceptual speed
.
Decreased numeric ability
.
Which change happens to the brain during senescence?
As we age our
brains shrink in volume
, particularly in the frontal cortex. As our vasculature ages and our blood pressure rises the possibility of stroke and ischaemia increases and our white matter develops lesions. Memory decline also occurs with ageing and brain activation becomes more bilateral for memory tasks.
What happens to the brain in late adulthood?
Many molecular changes are due in part to a reduction in the size of the brain, as well as loss of brain plasticity. … The
brain begins to lose neurons
in later adult years; the loss of neurons within the cerebral cortex occurs at different rates, with some areas losing neurons more quickly than others.
Which of the following is one of the earliest symptoms of Alzheimer disease quizlet?
Memory problems
are typically one of the first signs of cognitive impairment related to Alzheimer's disease. Decline in non-memory aspects of cognition, such as word-finding, vision/spatial issues, and impaired reasoning or judgment, may also signal the very early stages of Alzheimer's disease.
What are the main findings of longitudinal studies in regards to cognitive functioning in late adulthood?
Terms in this set (9)
Use it or lose it- what are the main findings of longitudinal studies regards to cognitive functioning?
The brain loses weight and volume with age
, and there is a general slowing of function in the central nervous system that begins in middle adulthood and increases in late adulthood.
