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.
1 Norepinephrine and epinephrine: When norepinephrine or epinephrine is the transmitter, the fiber is termed adrenergic (adrenaline being another name for epinephrine). 2  In the sympathetic system, norepinephrine mediates the transmission of nerve impulses from autonomic postganglionic nerves to effector organs.. Effects of stimulation of the sympathetic division: The effect of sympathetic output is to increase heart rate and blood pressure, to mobilize energy stores of the body, and to increase blood flow to skeletal muscles and the heart while diverting flow from the skin and internal organs.
