Age Related Cognitive Decline

Cognitive testing situations can be stressful for both younger and older adults, but threats of cognitive evaluation may be particularly salient among anxious older individuals as they tend to be more concerned than younger adults about their cognitive abilities and age-related cognitive decline. We examined age-related differences in the effect of anxiety on cortisol responses during cognitive testing in a sample of 27 younger ( M = 19.8) and 29 older ( M = 71.2) adults. Older adults with higher anxiety also had higher during-task cortisol (suggesting higher reactivity to testing) than older adults with lower anxiety and young adults. There was no effect of anxiety on cortisol for younger adults. Simultaneously examining subjective (state anxiety) and physiological (cortisol response) indicators of threat during cognitive testing appears to be especially important for older adults with higher state anxiety. The results are important for understanding cortisol reactivity, particularly in older adults. Researchers who administer cognitive tests to older adults and clinicians who work with older adults with cognitive concerns and/or anxiety may want to consider how they present their material.

Abstract Although it is well established that stress is negatively associated with cognitive functioning, less is known about age differences in the effects of stressors and anxiety on state anxiety and physiological reactivity (i.e., changes in cortisol). The current study examined state anxiety and cortisol reactivity during a series of cognitive tasks in a sample of younger (n=26) and older (n=29) adults. Participants completed the State-Trait Anxiety Inventory prior to cognitive testing and provided six salivary cortisol samples throughout one testing session: two cortisol samples prior to cognitive testing, three samples during testing, and one sample after testing. Six cognitive tasks were administered that measured attention span, declarative memory, and processing speed. Results indicated a significant interaction effect of age by time with younger adults’ cortisol linearly decreasing during the testing session and older adults’ cortisol showing a quadratic trend. A second interaction was found between age and state anxiety whereby older adults who reported more anxiety had higher cortisol levels during the cognitive testing session than both the older adults who reported low levels of anxiety and the younger adults. Only age (not cortisol or anxiety) was significantly related to cognitive performance. Results from this study suggest that standard cognitive testing could be anxiety producing for older adults, particularly for those who are already anxious. Future investigations should examine age-related differences in the processes linking anxiety and cortisol to specific types of performance, such as memory and attention.

Age-related declines for many sensory and cognitive abilities are greater for males than for females. The primary purpose of the present investigation was to consider whether age-related changes in lipreading abilities are similar for men and women by comparing the lipreading abilities of separate groups of younger and older adults. Older females, older males, younger females and younger males completed vision-only speech recognition tests of: (1) 13 consonants in a vocalic /i/-C-/i/ environment; (2) words in a carrier phrase; and (3) meaningful sentences. In addition to percent correct performance, consonant data were analyzed for performance within viseme categories. The results suggest that while older adults do not lipread as well as younger adults, the difference between older and younger participants was comparable across gender. We also found no differences in the lipreading abilities of males and females, regardless of stimulus type (i.e., consonants, words, sentences), a finding that differs from some reports by previous investigators (e.g., Dancer, Krain, Thompson, Davis, & Glenn, 1994). El deterioro relacionado con la edad de muchas habilidades sensoriales y cognitivas es mayor para los hombres que para las mujeres. El propósito primario de la presente investigación fue considerar si los cambios relacionados con la edad en la habilidad de leer los labios eran similares para hombre y mujeres, comparando las habilidades de lectura labial de grupos separados de adultos jóvenes y viejos. Mujeres viejas, hombres viejos, mujeres jóvenes y hombres jóvenes completaron pruebas de reconocimiento del lenguaje únicamente por medio de la visión de: (1) 13 consonantes en un ambiente vocálico /i/-C-/i/; (2) de palabras en una frase portadora; y (3) de frases significativas. Además del porcentaje correcto de desempeño, los datos de las consonantes se analizaron en cuanto a desempeño dentro de las categorías de visemas. Los resultados sugieren que mientras los adultos más viejos no leen los labios tan bien como los adultos más jóvenes, las diferencias entre participantes más viejos y más jóvenes fueron comparables entre los géneros. Tampoco encontramos diferencias en las habilidades de lectura labial de hombres y mujeres, sin importar el tipo de estímulo (p.e., consonantes, palabras, frases), un hallazgo que difiere con algunos reportes de investigadores previos (p.e., Dancer, Krain, Thompson, Davis, & Glenn, 1994).

Purpose Older adults exhibit difficulty understanding speech that has been experimentally degraded. Age-related changes to the speech mechanism lead to natural degradations in signal quality. We tested the hypothesis that older adults with hearing loss would exhibit declines in speech recognition when listening to the speech of older adults, compared with the speech of younger adults, and would report greater amounts of listening effort in this task. Method Nineteen individuals with age-related hearing loss completed speech recognition and listening effort scaling tasks. Both were conducted in quiet, when listening to high- and low-predictability phrases produced by younger and older speakers, respectively. Results No significant difference in speech recognition existed when stimuli were derived from younger or older speakers. However, perceived effort was significantly higher when listening to speech from older adults, as compared with younger adults. Conclusions For older individuals with hearing loss, natural degradations in signal quality may require greater listening effort. However, they do not interfere with speech recognition—at least in quiet. Follow-up investigation of the effect of speaker age on speech recognition and listening effort under more challenging noise conditions appears warranted.

Age Related Cognitive Decline

ABSTRACTOlder adults experience more problems than younger people when using everyday technological devices such as personal computers, automatic teller machines and microwave ovens. Such problems may have serious consequences for the autonomy of older adults since the ability to use technology is becoming essential in everyday life. One potential cause of these difficulties is age-related decline of cognitive functions. To test the role of cognitive abilities in performing technological tasks, we designed the Technological Transfer Test (TTT). This new and ecologically valid test comprises eight technological tasks that are common in modern life (operating a CD player, a telephone, an ATM, a train-ticket vending machine, a microwave-oven, an alarm clock, a smart card charging device and a telephone voice menu). The TTT and a comprehensive battery of cognitive tests were administered to 236 healthy adults aged 64–75 years on two separate occasions. The results demonstrated that the performance time for five of the eight tasks was predicted by cognitive abilities. The exact cognitive functions affecting technological performance varied by the technological task. Among several measures and components of cognition, the speed of information processing and cognitive flexibility had the greatest predictive power. The results imply that age-related cognitive decline has a profound effect on the interaction between older adults and technological appliances.

Background: Although numerous studies have suggested that the gradually increasing selective preference for positive information over negative information in older adults depends on cognitive control processes, few have reported the characteristics of different attention stages in the emotional processing of older individuals. The present study used a real-time eye-tracking technique to disentangle the attentional engagement and disengagement processes involved in age-related positivity effect (PE).Methods: Eye movement data from a spatial-cueing task were obtained for 32 older and 32 younger healthy participants. The spatial-cueing task with varied cognitive loads appeared to be an effective way to explore the role of cognitive control during the attention engagement and disengagement stages of emotion processing.Results: Compared with younger adults, older participants showed more positive gaze preferences when cognitive resources were sufficient for face processing at the attention engagement stage. However, the age-related PE was not observed at the attention disengagement stage because older adults had more difficulty disengaging from fearful faces than did the younger adults due to the consumption of attention by the explicit target judgment.Conclusion: The present study highlights how cognitive control moderates positive gaze preferences at different attention processing stages. These findings may have far-reaching implications for understanding, preventing, and intervening in unsuccessful aging and, thus, in promoting active and healthy aging.

Framing effect studies indicate that individuals are risk averse for decisions framed as gains but risk-seeking for decisions framed as losses. Findings of age-related differences in susceptibility to framing are mixed. In the current study, we examined emotional arousal in two decision tasks (life saving vs. money gambling) to evaluate the effects of emotion on age differences in the framing effect. When cognitive abilities and styles were controlled, there was a framing effect in the younger group in the life-saving task, a high-emotional arousal task, while older adults did not display this classic framing effect pattern. They showed risk aversion in both positive and negative framing. Age differences existed in the framing effect. Conversely, younger and older adults in the money-gambling task both displayed the framing effect; there was no age difference. When the cognitive abilities were not controlled, the pattern of results in the high-emotional arousal task remained unchanged, while greater framing effects were found, from the perspective of effect size, for older than younger adults in the low-emotional arousal task. Limited cognitive resources would not hamper older adults’ performances when their emotional arousal was high. However, older adults with low-level emotional arousal were more susceptible than younger adults to framing because of declining cognitive capacities. This implied the importance of emotion in older adults’ decision making and supported the selective engagement hypothesis.

The Relationship

Epidemiological studies fairly convincingly suggest that higher intakes of fatty fish and n-3 fatty acids are associated with reduced risk of Alzheimer's disease (AD). DHA in plasma is normally positively associated with DHA intake. However, despite being associated with lower fish and DHA intake, unexpectedly, plasma (or brain) DHA is frequently not lower in AD. This review will highlight some metabolic and physiological factors such as ageing and apoE polymorphism that influence DHA homeostasis. Compared with young adults, blood DHA is often slightly but significantly higher in older adults without any age-related cognitive decline. Higher plasma DHA in older adults could be a sign that their fish or DHA intake is higher. However, our supplementation and carbon-13 tracer studies also show that DHA metabolism, e.g. transit through the plasma, apparent retroconversion and β-oxidation, is altered in healthy older compared with healthy young adults. ApoE4 increases the risk of AD, possibly in part because it too changes DHA homeostasis. Therefore, independent of differences in fish intake, changing DHA homeostasis may tend to obscure the relationship between DHA intake and plasma DHA which, in turn, may contribute to making older adults more susceptible to cognitive decline despite older adults having similar or sometimes higher plasma DHA than in younger adults. In conclusion, recent development of new tools such as isotopically labelled DHA to study DHA metabolism in human subjects highlights some promising avenues to evaluate how and why DHA metabolism changes during ageing and AD.

AbstractSensitivity to repetitions in sound amplitude and frequency is crucial for sound perception. As with other aspects of sound processing, sensitivity to such patterns may change with age, and may help explain some age-related changes in hearing such as segregating speech from background sound. We recorded magnetoencephalography to characterize differences in the processing of sound patterns between younger and older adults. We presented tone sequences that either contained a pattern (made of a repeated set of tones) or did not contain a pattern. We show that auditory cortex in older, compared to younger, adults is hyperresponsive to sound onsets, but that sustained neural activity in auditory cortex, indexing the processing of a sound pattern, is reduced. Hence, the sensitivity of neural populations in auditory cortex fundamentally differs between younger and older individuals, overresponding to sound onsets, while underresponding to patterns in sounds. This may help to explain some age-related changes in hearing such as increased sensitivity to distracting sounds and difficulties tracking speech in the presence of other sound.

Age Related Cognitive Decline

Healthy aging is associated with a multitude of structural changes in the brain. These physical age-related changes are accompanied by increased variability in neural activity of all kinds, and this increased variability, collectively referred to as “neural noise,” is argued to contribute to age-related cognitive decline. In this study, we examine the relationship between two particular types of neural noise in aging. We recorded scalp EEG from younger (20–30 years old) and older (60–70 years old) adults performing a spatial visual discrimination task. First, we used the 1/ f-like exponent of the EEG power spectrum, a putative marker of neural noise, to assess baseline shifts toward a noisier state in aging. Next, we examined age-related decreases in the trial-by-trial consistency of visual stimulus processing. Finally, we examined to what extent these two age-related noise markers are related, hypothesizing that greater baseline noise would increase the variability of stimulus-evoked responses. We found that visual cortical baseline noise was higher in older adults, and the consistency of older adults' oscillatory alpha (8–12 Hz) phase responses to visual targets was also lower than that of younger adults. Crucially, older adults with the highest levels of baseline noise also had the least consistent alpha phase responses, whereas younger adults with more consistent phase responses achieved better behavioral performance. These results establish a link between tonic neural noise and stimulus-associated neural variability in aging. Moreover, they suggest that tonic age-related increases in baseline noise might diminish sensory processing and, as a result, subsequent cognitive performance.

Focused attention on expected voice features, such as fundamental frequency (F0) and spectral envelope, may facilitate segregation and selection of a target talker in competing talker backgrounds. Age-related declines in attention may limit these abilities in older adults, resulting in poorer speech understanding in complex environments. To test this hypothesis, younger and older adults with normal hearing listened to sentences with a single competing talker. For most trials, listener attention was directed to the target by a cue phrase that matched the target talker’s F0 and spectral envelope. For a small percentage of randomly occurring probe trials, the target’s voice unexpectedly differed from the cue phrase in terms of F0 and spectral envelope. Overall, keyword recognition for the target talker was poorer for older adults than younger adults. Keyword recognition was poorer on probe trials than standard trials for both groups, and incorrect responses on probe trials contained keywords from the single-talker masker. No interaction was observed between age-group and the decline in keyword recognition on probe trials. Thus, reduced performance by older adults overall could not be attributed to declines in attention to an expected voice. Rather, other cognitive abilities, such as speed of processing and linguistic closure, were predictive of keyword recognition for younger and older adults. Moreover, the effects of age interacted with the sex of the target talker, such that older adults had greater difficulty understanding target keywords from female talkers than male talkers.
