New analysis exhibits that sufferers who’ve had contact with the hospital because of critical glandular illness have a higher danger of subsequently growing melancholy. The examine from iPSYCH is the biggest but to indicate a correlation between glandular fever and melancholy.
The overwhelming majority of Danes have had glandular fever – additionally known as mononucleosis – earlier than maturity. And for the overwhelming majority of them, the illness will be cured at house with throat lozenges and just a little further care. However for some, the illness is so critical that they should go to the hospital.
A brand new analysis end result now exhibits that exactly these sufferers who’ve been in touch with the hospital in reference to their sickness, have a higher danger of struggling a melancholy later.
“Our examine exhibits that it’s related to a forty per cent higher relative danger of growing melancholy, if the affected person has been in touch with a hospital because of glandular fever,” says Professor and Analysis Director Michael Eriksen Benrós from the Psychological Well being Centre, Copenhagen, the College of Copenhagen and Aarhus College, who’s behind the examine.
Demonstrates a correlation
The danger was appreciable for as much as 4 years after the an infection.
“It’s well-known that mononucleosis an infection could cause long-term fatigue afterwards, and we will now see that there’s additionally an elevated danger of growing precise melancholy, which requires contact with the hospital. Luckily, this was solely the case for 1 out of 35 with mononucleosis an infection throughout the examine’s follow-up, he says.
The examine is a register-based examine which has adopted 1,440,590 Danes, of whom 12,510 had contact with the hospital because of glandular fever, and of those, 358 – corresponding to a few per cent – subsequently developed melancholy that required hospital contact.
Earlier research of the correlation between glandular fever and subsequent melancholy have primarily been small research and the correlation has subsequently been unclear. This examine is the primary main examine in a position to show the correlation with a subsequent danger of melancholy with nice statistical power.”

Impacts younger folks
Glandular fever impacts younger folks aged 10-25 years particularly, and signs embrace fatigue, ache within the neck, fever and swollen lymph nodes on the neck, typically accompanied by fatigue within the months following. It’s also typically younger individuals who come into contact with the hospital as a result of their signs are critical.
“This data is essential – each for the affected person and their mother and father, but additionally to a fantastic extent for common practitioners – as there’s an elevated danger of melancholy after the an infection,” explains Nina Vindegaard.
Based on Michael Eriksen Benrós, a part of the reason for the elevated danger could also be that the mind is affected by the an infection:
“We all know that mononucleosis an infection can result in long-term fatigue, however the precise underlying mechanisms for the way this occurs to a higher extent for this specific an infection in comparison with many different infections have not been recognized. The overall hypotheses are that it occurs by means of activation of the immune system, which can additionally lie behind the elevated danger of melancholy,” he says.
Background for the outcomes
The register-based examine adopted 1.44 million Danes born between 1977-2005, with 12,510 of those having had contact with the hospital contact with mononucleosis. Mononucleosis an infection was related to a forty % elevated relative danger of subsequently growing melancholy. Relative danger is the chance of an undesired final result within the therapy group divided by the identical danger within the management group.
