Study: Mental Skills Slow With Age, But Seniors Gain in Other Ways

Seniors, there’s good news and bad from a new study of mental health. The brain-centered research confirms that mental skills do decline with age — but it also finds many people over 60 having better psychological health than folks in their 20s.

“We wanted to better understand the interplay between cognition and mental health across aging, and whether they rely on activation of similar or different brain areas,” explained senior study author Jyoti Mishra. She is director of the Neural Engineering and Translation Labs (NEATLabs) at University of California, San Diego, and an associate professor of psychiatry at the university’s School of Medicine.

The researchers included 62 younger adults and 54 older adults in the study, evaluating their mental health and surveying symptoms of anxiety, depression, loneliness and overall mental well-being. They also asked participants to perform several mentally demanding tasks while the scientists measured brain activity using electroencephalography (EEG).

The EEG recordings showed greater activity in anterior portions of the brain’s default mode network in older adults during the tasks. These are areas of the brain that are typically active when someone ruminates, daydreams or allows their mind to wander. It is usually suppressed during goal-oriented tasks.

“The default mode network is useful in other contexts, helping us process the past and imagine the future, but it’s distracting when you’re trying to focus on the present to tackle a demanding task with speed and accuracy,” Mishra explained in a university news release.

The team found that while the default mode network seemed to interfere with thinking, several other brain areas appeared to improve it. Task performance used different parts of the brain, depending on whether the participants were older or younger.

In younger adults this was associated with greater activity in the dorsolateral prefrontal cortex, part of the brain’s executive control system.

Yet in older adults, those with better thinking performance had greater activity in the inferior frontal cortex, an area that helps guide attention and avoid distractions.

The dorsolateral prefrontal cortex that the younger adults used degrades with age. The research team suggested that older adults may be compensating during tasks by turning to the inferior frontal cortex.

It may be possible to strengthen frontal networks using brain stimulation methods while also suppressing the default mode network through mindfulness meditation. The researchers said they are looking for therapeutic inventions to do this.

“These findings may provide new neurological markers to help monitor and mitigate cognitive [thinking] decline in aging, while simultaneously preserving well-being,” Mishra said.

The findings could also inspire efforts to improve mental health in young adults.

“We tend to think of people in their 20s as being at their peak cognitive performance, but it is also a very stressful time in their lives, so when it comes to mental well-being, there may be lessons to be learned from older adults and their brains,” Mishra said.

The findings were published in Psychology and Aging.

Thai Noodle Salad

Ingredients

12 oz egg-free noodles
1 large carrot, cut into thin strips
1 bunch of asparagus, trimmed and cut into 1-1/2-inch lengths
1 red (bell) pepper, seeded and cut into fine strips
4oz mangetouts (snow peas), trimmed and halved
4oz baby corn cobs, halved lengthways
4oz beansprouts
4oz can water chestnuts, drained and finely sliced

Dressing

3 tbsp roughly torn fresh basil
5 tbsp roughly chopped fresh mint
1 cup coconut milk
2 tbsp dark sesame oil
1 tbsp grated fresh root ginger
2 garlic cloves, finely chopped
juice of 1 lime
2 spring onions (scallions), finely chopped
salt and cayenne pepper

Garnish

1 lime, cut into wedges
2oz roasted peanuts, roughly chopped
fresh coriander (cilantro) leaves

Method

  1. Make the dressing. Mix the basil, mint, coconut milk, sesame oil, ginger, garlic, lime juice and spring onions. Season with salt and cayenne pepper.
  2. Cook the egg-free noodles in a pan of boiling water until just tender, following the instructions on the packet. Drain, rinse under cold running water and drain again, then set aside.
  3. Cook the carrot, asparagus, pepper, mangetouts and baby corn cobs in a pan of boiling water until tender, but still crisp. Drain, plunge them immediately into cold water and drain again.
  4. Toss the noodles, vegetables and dressing together to combine. Arrange in individual bowls and garnish with the lime wedges, peanuts and coriander.

Makes 4 to 6 servings.
