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.
Sebaceous glands. - oil producing-holocrine-associated with hair follicles-sebum secreting secrete products via apoptosis-secrete products mostly onto hair follicles-lanolin-usually opens up into a hair follicle-coats the scalp hair with oil-blockage and infection can cause pimples-form of sudoriferous gland.- modified mammary glands. sweat secreting-eccrine-merocrine-secrete products via exocytosis-apocrine-mammary glands-secrete directly onto the skin surface-secretions are 99% water and slightly acidic pH-simple tubular structures-responsible for diaphoresis-secretion of pheromones.
