Several population-based studies have reported an elevated risk of death by suicide, ^[1] suicide attempts, ^[2] and suicide ideation among traumatic brain injury survivors ^[3]. It has been suggested that this is related to hormone deficiencies caused by pituitary damage, a frequent consequence of head injury ^[4], ^[5].
