End-of-life mental decline involves confusion (delirium), disorientation, memory loss, hallucinations, mood swings, and personality changes, often due to the body shutting down or medication effects, leading to reduced awareness, increased anxiety, agitation, or withdrawal, though hearing often remains intact and people can still sense comfort. This decline progresses from disorientation and memory issues to decreased consciousness and eventual unresponsiveness, with signs like hallucinations and restlessness being common, but manageable with palliative care.
“We found accelerated changes in people's mental skills that indicated a terminal decline phase years before death.” The start of the decline is different for various cognitive abilities. Perceptual speed, which measures how quickly people can compare figures, begins declining nearly 15 years before death.
As brain and judgment functions decline, your loved one may become confused about the day, time, others' identities, or his or her own identity. Often, those nearing the end of life mistake people in the present for people they knew in the past. Or, they may forget individuals altogether.
The following symptoms are often a sign that the person is about to die:
Some common symptoms of many types of organ failure include:
The transition into active dying typically begins when a person stops eating and drinking, becomes mostly unresponsive, and shows significant physical decline. Breathing patterns may shift dramatically—pausing for long intervals or becoming more rapid and shallow.
Made famous by her pioneering work in near-death studies, Kübler-Ross conceptualized five common emotional stages experienced by her clients facing terminal illness: denial, anger, bargaining, depression, and acceptance (DABDA).
As people get closer to dying, they may sleep more, become drowsy or be difficult to wake. They may fall asleep while talking. A person may slowly lose consciousness in the days or hours before death. When visiting someone with advanced cancer, be aware that visiting may be tiring and difficult for the dying person.
Sudden death, terminal illness, organ failure, and frailty are the four most common types of illness trajectories found in end-of-life care.
The end-of-life process varies greatly, lasting from hours to weeks or even months, depending on the individual and illness, with the "active dying" phase often taking days or hours as the body slows down, though some symptoms can appear months earlier in the pre-active stage. It's a gradual, natural winding down, not a fixed timeline, with some experiencing peaceful transitions while others may have periods of restlessness or confusion.
The 3 C's of grief are Control, Connection, and Continuity - three fundamental psychological needs that become disrupted after loss and require intentional attention during the grieving process.
In the last 48 hours of life, common symptoms include significant changes in breathing (faster, slower, pauses, noisy), increased sleep/unresponsiveness, confusion or delirium, cold/mottled skin (especially extremities), decreased appetite/thirst, loss of bladder/bowel control, and restlessness, often with a "death rattle" from fluid buildup, as the body slows down and organs begin to shut down, emphasizing comfort care.
What to do for someone who is dying
Terminal lucidity (also known as rallying, terminal rally, the rally, end-of-life-experience, energy surge, the surge, or pre-mortem surge) is an unexpected return of consciousness, mental clarity, or memory shortly before death in individuals with severe psychiatric or neurological disorders.
Hospice Isn't About Giving Up
It's not a place to speed up the process of dying. A doctor suggesting hospice does not mean they're giving up on providing care and medical treatment. It's end-of-life care, but this doesn't mean giving up hope. It means shifting focus from curative treatments to comfort and support.
Symptoms
Change in breathing.
Changes may include Cheyne-Stokes breathing or shallow breaths with periods of no breathing for a few seconds to a minute, as well as rapid, shallow panting. These patterns are common and indicate a decrease in circulation as the body shuts down.
Some proponents of the trifunctional hypothesis distinguish two types of threefold deaths in Indo-European myth and ritual. In the first type of threefold death, one person dies simultaneously in three ways. He dies by hanging (or strangulation or falling from a tree), wounding, and by drowning (or poison or burning).
What other signs might there be that death is near? One is 'terminal agitation' or restlessness. This often appears as a need to get out of bed, agitated behaviour or commonly plucking of the sheets or 'knitting' of the hands. They might reach out as if towards something or somebody.
A conscious dying person can know if they are on the verge of dying. Some feel immense pain for hours before dying, while others die in seconds. This awareness of approaching death is most pronounced in people with terminal conditions such as cancer.
This period runs from 3 to 72 hours after death. The early post-mortem phase is most frequently estimated using the classical triad of post-mortem changes – rigor mortis, livor mortis, and algor mortis.
You can simply sit with the person and perhaps hold their hand. Hearing is said to be the last sense to go, so you may want to talk to the person or even have a conversation among the people in the room so that the person knows they are not alone. You could read aloud, sing or hum or play some of their favourite music.
Physical signs that death is near include:
The hardest deaths to grieve often involve a child, a spouse/life partner, or a loss due to suicide or homicide, as these challenge fundamental beliefs about life's order, shatter primary support systems, or add layers of trauma, guilt, and unanswered questions, leading to potentially complicated grief. However, grief is deeply personal, and the "hardest" loss is ultimately the one that feels most significant to the individual.
Voluntary Stop Eating and Drinking (VSED)
Many people are unaware that stopping treatment can result in a peaceful death. For example, people on dialysis for kidney failure may be able to die peacefully by stopping dialysis. However, stopping medical treatments may increase discomfort or suffering.
