    Progesterone has a neuroprotective and promyelinating effects in the nervous system.  Progesterone increases BDNF.  Progesterone increases proliferation and differentiation of oligodendrocyte progenitor cells which will increase myelin production.

hbot hyperbaric therapy hyperbaric brain concussion post concussion syndrome TBI traumatic brain injury

  • The changes in SPECT images after treatment indicate that HBOT led to reactivation of neuronal activity in stunned areas that seemed normal under CT and MRI imaging. While SPECT imaging has a limited spatial resolution (compared, for example, to fMRI), the changes in activity were sufficiently robust to be clearly detected by the SPECT images.
  • HBOT might initiate a cellular and vascular repair mechanism and improve cerebral vascular flow
  • HBOT induces regeneration of axonal white matter [61], [62], [63], [64], has positive effect upon the myelinization and maturation of injured neural fibers [65], and can stimulate axonal growth and increase the ability of neurons to function and communicate with each other

  • HBOT was found to have a role in initiation and/or facilitation of angiogenesis and cell proliferation processes needed for axonal regeneration [67].
  • The observed reactivation of neuronal activity in the stunned areas found here, along with similar results in post-stroke patients
  • At the cellular level, HBOT can improve cellular metabolism, reduce apoptosis, alleviate oxidative stress and increase levels of neurotrophins and nitric oxide through enhancement of mitochondrial function (in both neurons and glial cells)
  • HBOT may promote the neurogenesis of endogenous neural stem cells
  • With regard to secondary injury mechanisms in mTBI, HBOT can initiate vascular repair mechanism and improve cerebral vascular flow [58], [59], [68], [69], promote blood brain barrier integrity and reduce inflammatory reactions [28] as well as brain edema
  • It might be possible that HBOT enables the metabolic change simply by supplying the missing energy/oxygen needed for those regeneration processes.

    Hbot therapy, according to study, induces neuroplasticity and improves brain function in post concussion syndrome and those with mTBI.  The important point about this study was that the study was done years after the injury; what if the therapy was employed immediately after...
