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 dimentia 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.
