Suppressing brain immune cells might prevent or delay the onset of dementia

Messy tangles of a protein called tau can be found in the brains of people with Alzheimer's disease and some other neurodegenerative diseases. In Alzheimer's, the tangles coalesce just before tissue damage becomes visible in brain scans and people start to become forgetful and confused.

Neurofeedback can change guilt-related brain connectivity in patients with Major Depression Disorder

A study published in the journal Neuroimage: Clinical found that patients with Major Depressive Disorder, who had recovered from symptoms, were able to strengthen some of their brain connections whilst thinking about guilt-evoking memories, thereby increasing their self-esteem.

Nervous system plays a role in age-related weakness

Aging is an inevitable and a normal process of life. As people grow older, they lose muscle mass caused by age-related sarcopenia. In older adults, the maintenance of muscle mass and strength contribute to mobility which impacts quality of life. One of the reasons why older adults become frail is because of age-related muscle weakness.
