  • Title: Cerebrospinal fluid neuropeptides in dementia.
    Author: Banki CM, Karmacsi L, Bissette G, Nemeroff CB.
    Journal: Biol Psychiatry; 1992 Sep 01; 32(5):452-6. PubMed ID: 1486150.
    Abstract:
    Cerebrospinal fluid concentrations of corticotropin-releasing hormone (CRH), thyrotropin-releasing hormone (TRH) and somatostatin (SRIF) were measured in 77 female inpatients with moderate to extreme dementia and in 17 elderly female controls. Both multi-infarct (MID) and Alzheimer-type (SDAT) demented patients had equally elevated CSF CRH and TRH but not SRIF levels as compared with the controls. This elevation was, however, not seen in patients with simple dementia while it was most prominent in those exhibiting marked depressive symptoms. It is concluded that depression rather than dementia itself may be associated with CSF CRH and TRH elevation in elderly patients with cognitive impairment.
