Hormonal systems profoundly influence traumatic brain injury. Understanding these connections helps explain the varied timing, patterns, and presentations of traumatic brain injury across the lifespan.
Key Hormones in Traumatic Brain Injury
Cortisol (the stress hormone): Chronically elevated cortisol from ongoing traumatic brain injury damages the hippocampus and dysregulates the entire stress response system.
Serotonin precursors: Hormonal fluctuations affect tryptophan availability and serotonin synthesis.
Estrogen and testosterone: Influence mood regulation directly and through effects on serotonin and dopamine systems.
Thyroid hormones: Thyroid dysregulation can mimic or worsen traumatic brain injury — always worth screening.
Life Transitions and Hormonal Traumatic Brain Injury
Hormonal transitions (puberty, postpartum, perimenopause, andropause) are high-risk periods for traumatic brain injury onset or worsening.
Addressing Hormonal Contributions to Traumatic Brain Injury
If hormonal factors contribute to your traumatic brain injury, treatment may include hormonal evaluation, targeted supplements, hormone therapy, or approaches that support hormonal regulation through lifestyle.
