  • Abnormalities evident via neuroradiography can include agenesis (absence) or hypoplasia of the corpus callosum, absence or incomplete development of the septum pellucidum, malformations of the pituitary gland, schizencephaly, cortical heterotopia, white matter hypoplasia, pachygyria, and holoprosencephaly. (wikipedia.org)
  • The anterior pituitary gland contributes to growth, metabolism, and sexual development. (wikipedia.org)

  • demonstrated that the production of melatonin exhibits a circadian rhythm in human pineal glands. (wikipedia.org)
  • ACTH
  • If the cortisol remains high, a blood test for ACTH may be done to determine if the pituitary is involved. (wikipedia.org)
  • Other signs include increased urination (and accompanying increased thirst), persistent high blood pressure (due to cortisol's enhancement of epinephrine's vasoconstrictive effect) and insulin resistance (especially common with ACTH production outside the pituitary), leading to high blood sugar and insulin resistance which can lead to diabetes mellitus.
