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.
How does the endocrine system work with signals? Glands of the endocrine system receive signals from outside stimuli. When a particular gland determines it is time to release a hormone, it signals other glands and hormone-producing agents to likewise release signals. This is called an axis. Each gland and organ work in unison to achieve a goal.
