An imaging study reveals why older adults are better at remembering positive events. The study, involving young adults (ages 19-31) and older adults (ages 61-80) being shown a series of photographs with positive and negative themes, found that while there was no difference in brain activity patterns between the age groups for the negative photos, there were age differences for the positive photos. In older adult brains, but not the younger, two emotion-processing regions (the ventromedial prefrontal cortex and the amygdala) strongly influenced the memory-encoding hippocampus.

Training in a mental imagery technique has been found to help multiple sclerosis patients in two memory domains often affected by the disease: autobiographical memory and episodic future thinking.
Older adults' distractability can be used to help put a face to a name
One important reason for the greater cognitive problems commonly experienced as we age, is our increasing difficulty in ignoring distracting and irrelevant information. But it may be that in some circumstances that propensity can be used to help memory.
Individuals vary in how they remember events
A study involving 66 healthy young adults (average age 24) has revealed that different individuals have distinct brain connectivity patterns that are associated with different ways of experiencing and remembering the past.
Older people less apt to recognize they've made a mistake
A small study comparing 38 younger adults (average age 22) and 39 older adults (average age 68) found that the older adults were less able to recognize when they made errors.
The simple test involved looking away from a circle that appeared in a box on one side of a computer screen. It’s hard not to look at something that’s just appeared, and each time the participant glanced at the circle before shifting their gaze, they were asked whether they had made an error. They were then asked to rate how sure they were of their answer.
Long-winded speech could be early sign of Alzheimer's

Absentmindedness can be an early warning sign of silent strokes
A study involving 54 older adults (55-80), who possessed at least one risk factor for a stroke, found that those with white matter damage caused by silent strokes reported poor attentiveness and being distracted more frequently on day-to-day tasks. Despite these complaints, about half of these people scored within the normal range on tests of attention and executive function.
It’s suggested that adults who notice that they frequently lose their train of thought or often become sidetracked may in fact be displaying early symptoms of cerebral small vessel disease.
Movie study confirms older people are more distractible
A study involving 218 participants aged 18-88 has looked at the effects of age on the brain activity of participants viewing an edited version of a 1961 Hitchcock TV episode (given that participants viewed the movie while in a MRI machine, the 25 minute episode was condensed to 8 minutes).
While many studies have looked at how age changes brain function, the stimuli used have typically been quite simple. This thriller-type story provides more complex and naturalistic stimuli.
Gist memory may be why false memories are more common in older adults
Do older adults forget as much as they think, or is it rather that they ‘misremember’?
A small study adds to evidence that gist memory plays an important role in false memories at any age, but older adults are more susceptible to misremembering because of their greater use of gist memory.
Higher aerobic fitness levels linked to fewer word failures in older adults
A small UK study involving 28 healthy older adults (20 women with average age 70; 8 men with average age 67), has found that those with higher levels of aerobic fitness experienced fewer language failures such as 'tip-of-the-tongue' states.
The association between the frequency of tip-of-the-tongue occurrences (TOTs) and aerobic fitness levels existed even when age and vocabulary size was accounted for. Education level didn't affect TOTs, but only a few of the participants hadn't gone to university, so the study wasn't really in a position to test this out.
