Abstract
Early efforts to identify the hypothalamic stimulating factor for growth hormone (GH) release from the pituitary inadvertently resulted in the discovery of a hypothalamic inhibitor of GH release [57]. Despite initial skepticism regarding its existence, this inhibiting factor, somatostatin (SS; also called somatotropin release-inhibiting factor, SRIF), was subsequently isolated and structurally characterized by Brazeau et al. [17]. As has been true for most of the brain neuropeptides identified over the last two decades, the known neuroregulatory effects of the tetradecapeptide SS have expanded far beyond its originally discovered role. The possibility that alterations in SS might reflect or contribute to the pathophysiology of disorders of the central nervous system (CNS) was first examined by Patel et al. in 1977 [75]. Subsequently, a variety of reports appeared describing decreased SS in brain and/or cerebrospinal fluid (CSF) of patients with several neuropsychiatric disorders, particularly Alzheimer’s disease and depression. These studies of SS in neuropsychiatric disorders will be reviewed in this chapter, as will the evidence supporting a role for SS as a modulator of CNS activity.
