It is a phenomenon that is reported by many.
But there is little evidence that the & # 39; midlifecrisis & # 39; exists, according to a psychologist.
Professor Nick Haslam, from the University of Melbourne, claims that midlife is a time of growth that requires a "customization process."
And he said that & # 39; not surprising & # 39; Studies have shown that older adults choose midlife as the phase they prefer most.
Psychology Professor Nick Haslam said the midlife crisis & # 39; little evidence & # 39; has an existing, and more a time for growth and processing change
Professor Haslam wrote in The Conversation that there is no solid core in life and that & # 39; crises & # 39; that occur at any other time may have happened.
& # 39; It is difficult enough to decide when the midlife crisis would occur & # 39 ;, he said. Middle-aged concepts are elastic and change as we age. & # 39;
Several studies that used surveys set middle age as something between the 30s and 70s, Professor Haslam said.
Although we define midlife, studies suggest that self-reported crises "just occur more often as we age", said Professor Haslam.
Evidence also indicates that life generally becomes more positive around this time because the personality becomes more stable.
WHEN ARE HUMAN BRAINS & # 39; OLD & # 39;
The human brain becomes & # 39; old & # 39; at only 25, research proposed in February 2017.
Cerebrospinal fluid (CSF), which is found in the brain and spinal cord, changes the rate of movement in people older than their mid twenties, a study of the University of Lancaster found.
These movements are linked to respiratory and heart rates, CSF changes being associated with conditions such as multiple sclerosis and high blood pressure.
It is unclear whether these CSF changes are associated with brain disorders that typically affect elderly people, such as dementia.
Earlier research suggests that the volume and weight of the brain begin to decline by about five per cent per decade when a person turns 40 years old.
Based on these findings, study author Professor Aneta Stefanovska added further research & # 39; can push new frontiers in the understanding and diagnosis of different neurodegenerative and age-related diseases to improve diagnostic procedures and patient prognosis. & # 39;
The discovery came to light during the development of a new method to investigate brain function, which has revealed the phase in life in which the brain begins to deteriorate.
Earlier research conducted by Imperial College London suggests that gray matter of the brain, which can cause the organ to function, shrinks during middle age and is related to cell death.
White matter, which makes communication between nerve clusters possible, also seems to drop around 40.
This is also the case when the damage to myelin sheath occurs. Myelin sheath is a fatty substance that surrounds nerve cells and provides a good function of the nervous system.
It is thought that these changes occur as a result of a reduction of the hormones dopamine and serotonin.
He pointed to a Swiss study, published in Gerontology in 2009, which showed that the older the participants were, the older they reported that their midlife crisis had occurred.
Psychoanalyst Elliot Jaques, who in 1965 the term & # 39; midlifecrisis & # 39; coined, thought it reflected the imminent recognition of death.
Others suggest that it may be related to children flying around the nest, caring for aging parents, starting to show and work chronic diseases.
However, it can be biologically rape, as chimpanzees and orangutans show signs of a dip in mood around a similar age.
The study, published in PNAS in 2012 by international researchers, found that monkeys at this age had the least enjoyment of social activities.
Although it is speculated that events can cause crises, there is no clear connection, Professor Haslam said.
"Crisis episodes may not be closely associated with adverse events in life," he said. Research often shows no clear links between setbacks and self-declared crises.
One study showing that reporting a midlife crisis was not associated with the recent experience of divorce, job loss or the death of a loved one. & # 39;
In general, people are making a positive transition to what they perceive as their midlife, Professor Haslam said.
& # 39; Psychological changes are generally positive during midlife. Personality becomes more firm and self-accepting, while positive emotion gradually rises gradually over the lifetime.
& # 39; The U-shaped life satisfaction curve notwithstanding, most change during midlife is positive. & # 39;
Professor Haslam said that a longitudinal study, published in the journal Assessment in 2000, found that American women ages 41 to 50 were more resilient as they got older, because they became less neurotic and self-conscious.
Middle-aged may shift for some, but there is little evidence that it is usually a period of crisis and despair & # 39 ;, said Professor Haslam.
& # 39; If there is a small dip in how people evaluate their fate – even if the lens is not worse than before – this is understandable.
& # 39; Psychologically, things often get better. & # 39;
