At least when it comes to mental health and cognition, young and old people can learn one thing or two from
In a new study published Sept.
"We wanted to better understand the interactions between cognitive and mental health, and whether they depend on the activation of similar or different brain regions," said senior author Jyoti Mishra, Ph.
The study sampled 62 healthy young adults in their 20s and 54 healthy adults
The results showed that anxiety, depression and loneliness were significantly more severe in young people, while mental health was better
EEG records show that older adults exhibit greater activity
"Default mode networks are useful in other situations, helping us process the past and imagine the future, but when you try to focus on the present to solve a demanding task quickly and accurately, it distracts you," Mishra said
While the default mode network seems to interfere with cognition, several other areas of the brain seem to improve it
The dorsolateral prefrontal cortex is known to degenerate with age, so researchers believe that increased activity in the subfrontal cortex may be a way
The team is currently investigating therapeutic interventions that strengthen these frontal networks, such as brain stimulation methods, while also suppressing the default mode network
"These findings may provide new neurolabels that can help monitor and alleviate cognitive decline during aging while staying healthy
The study may also inspire new ways
Co-authors of the study include Gillian Grennan, Pragathi Priyadharsini Balasubramani, Nasim Vahidi, Dhakshin Ramanathan and Dilip V.
The research was funded in part by the National Institute of Mental Health (T32-MH019934 grant), the NeuroAIDS Interdisciplinary Research Fellowship (grant R25MH081482), the UC San Diego Institute for Aging Research, the Brain and Behavioral Research Fund, the Cavilee Foundation, the Barros Wellcome Medical Scientist Career Award, and the Sanford Institute for Empathy and Compassion
