    Just the abstract is available online, but the neurophysiology of brain injury is well discussed here.  This process takes time.  In fact, most TBIs are mild and often go unreported/unrecognized until neurological deficits begin.

  • A number of age-related changes may be relevant: altered negative feedback of testosterone and hence less increase in luteinizing hormone (LH) with falling testosterone levels, increased sex hormone binding globulin (SHBG) and hence relatively reduced free testosterone and the likelihood of an age-related decline in testosterone receptor sensitivity
  • In the older male, the picture is complicated by various aging effects, including altered hypothalamo–pituitary feedback, increased testosterone binding and reduced receptor sensitivity
  • The neurophysiological basis of NPT is still disputed, but one plausible explanation is that REM sleep is associated with a ‘switching off’ of the noradrenergic cells in the locus coeruleus
