I came across and article about how the hormone somatostatin can affect intacranial hypertension. After reading this article, I researched the hormone. http://www.wisegeek.com/what-is-somatostatin.htm I found that somatostatin deficiencies can cause symptoms similiar to those of Chiari malformation. Since somatostain is a growth hormone, could a deficiency conrtibute to the cause of Chiari? Could the reason that the tonsils extend too much be due to a smaller skull caused by a deficiency? I realize that it would be illogical to hypothesize that somatostatin causes Chiari and many disorders all on it's own, but could it be a contributing factor? Thanks in advance for replies!
