A new research paper from Sweden discusses the condition termed exhaustion syndrome, also called burnout and exhaustion depression.

Investigators believe the condition leaves objectively measurable changes in the brain — including reduced activity in the frontal lobes and altered regulation of the stress hormone cortisol.

A research team at Umeå University wanted to study whether this patient group had any susceptibility factors that could explain the development of their disorder.

The patient group is distinguished by being anxious and pessimistic, with a weak sense of self, common in many psychiatric disorders. What was special about this group was that they stood out as persistent, ambitious, and pedantic individuals.

Being ambitious, fastidious, and overachieving also appears to make a person more prone to exhaustion syndrome.

Regulation of the stress hormone cortisol is also impacted in the group, with altered sensitivity in the hypothalamic-pituitary-adrenal axis (HPA axis).

According to Agneta Sandström’s dissertation, individuals with exhaustion syndrome show reduced brain activity in parts of the frontal lobes. Her paper addresses whether it is possible to use neuropsychological tests to confirm and describe the cognitive problems reported by patients suffering from exhaustion syndrome.

Above all, patients with exhaustion syndrom demonstrate problems regarding attention and working memory. Patients were asked to perform working memory tests while lying in a functional magnetic resonance imaging machine.

Exhaustion syndrome patients proved to have a different activity pattern in the brain when they performed a language test of their working memory, and they also activate parts of the frontal lobe less than healthy subjects and a group of patients who had recently developed depression.
