Hormones

Introduction

Hormonal symptoms are caused by changes in pituitary function following a brain injury. Diagnosis can be difficult in the early stages however some rehabilitation units test for changes as part of their assessment.

Cortisol

Recent studies have found that there could be links between the role that cortisol plays in passing messages from the gut-brain and brain health. Overproduction of cortisol in the early stages of brain injury could affect this system, as could depletions commonly found in people who live with the effects long-term.

Further studies are needed to identify the role cortisol plays in the production of serotonin and other important hormones and neurotransmitters. These may play a role in the exacerbation and prolongment of fatigue and affect gut bacteria health creating the vicious circle which people find hard to break.
