The CCG has received some information concerning ME/CFS patients who's symptoms could relate to a past head injury.
The information is supported by the UK Acquired Brain Injury Forum (UKABIF) and the Child Brain Injury Trust. Head Injuries can have a common however little known complication, the pituitary gland is damaged in around 25% of serious cases, giving rise to impotence, infertility, depression, obesity and fatigue. This can also occur after concussion, symptoms may not necessarily show immediately, sometimes they appear months or years after trauma, hormone treatment can be effective.
In addition the number of suicides following a serious head injury is four times higher than average and the number following concussion is three times higher than average.
