Prolonged Grief Disorder has certain recognizable risk factors

Grief is defined as the anguish and physiological distress experienced after significant loss

It usually occurs following the death of a loved one, and symptoms may include confusion, apprehension about the future, separation anxiety, and ruminating on the past.

Grieving is a process—no need to rush social activities or major life decisions, if possible

Individuals experiencing grief may find comfort through counseling, online support groups, support books, and activities like volunteering. Each of these resources can help individuals build a community or new daily patterns when navigating intense anguish.

Grief rewires the human brain

The human brain handles stress and emotional traumas similarly. In response to the emotional stress of a situation like the death of a loved one, divorce, or abuse, the brain may strengthen or weaken connections between nerves to form new neural connections. Over time, chronic stress can diminish brainpower, reducing overall nerve growth and memory to shift resources to enable elevated fear responses and enable humans to survive.

Grieving primate mothers will carry dead infant for long after death—and others will comfort her

An examination of infant corpse carrying practices among non-human primate mothers found that 40 species of primate mothers will carry around their dead infant for days, weeks, or even months.

People with schizophrenia typically die 9 years earlier than the general population

The syndrome, which affects roughly 1 in 233 adults, is often associated with other serious health issues, including cardiovascular, metabolic, and infectious diseases, which may contribute to early deaths.
