In the process of supporting the family I came across research that shows this is far more common than previously thought and most cases are undiagnosed - tragically, because treatment can be successfully given.
GPs are well placed to pick this up, for example by questioning whether depressed patients have had a head injury and referring them for neurological and endocrine checks. Hormone replacement may be more appropriate than antidepressants.
Neither my GP colleagues nor I had been aware of this, and hope that my friend's loss might help to avoid a further tragedy resulting from hypo-pituitarism secondary to TBI.
