Because RAD is lacking a background of significant research due to its rarity, the causes and risk factors as to why children develop reactive attachment disorder are not entirely conclusive. Some examples of causes that have been linked to possibly impacting the development of RAD include:
Central Nervous System (Brain and Spinal Cord) and Peripheral Nervous System (Cranial Nerves, Spinal Nerves, and Ganglia). This is the control center for the entire nervous system.All body sensations must be relayed from receptors to the CNS if they are to be interpreted and acted on. All of the nerve impulses that stimulate muscles to contract and glands to secrete must also originate in the CNS.
Adrenal glands work interactively with the hypothalamus and pituitary gland in the brain. For example, for the adrenal gland to produce corticosteroid hormones: The hypothalamus produces corticotropin-releasing hormone (CRH) that stimulates the pituitary gland to produce adrenocorticotropin hormone (ACTH).The ACTH stimulates the adrenal glands to make and release corticosteroid hormones into the blood.Both the hypothalamus and the pituitary gland can sense whether the blood has the right amount of an adrenal hormone (cortisol) in it.he ACTH stimulates the adrenal glands to make and release corticosteroid hormones into the blood.
