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.
DHEA-S is an androgen that is secreted by the adrenal gland. It is normal for women to have DHEA-S levels anywhere between 35-430 ug/dl. Most women with PCOS tend to have DHEA-S levels greater than 200 ug/dl. Prolactin. Prolactin is a pituitary hormone that stimulates and sustains milk production in nursing mothers. Prolactin levels are usually normal in women with PCOS, generally less than 25 ng/ml.
