Hormone therapy (because the hypothalamus and pituitary gland can be affected after an impact to the brain, therefore affecting the function of these two very important hormone regulators). This is achieved by the hypothalamus inside the brain. The hypothalamus controls body temperature, hunger, important aspects of parenting and attachement behaviours, thirst, fatigue, sleep, and internal clock. The hypothalamus functions as a type of thermostat for the body. A change in the hormone levels can effect mood and physical well-being, a reduction in growth hormone can result in strength, aerobic ability, problems with attention, memory, depression, anxiety and fatigue.
