Circadian rhythms of blood components in dementia senilis.
In eleven patients with dementia senilis circadian rhythms of hematocrit, hemoglobin, erythrocytes, leukocytes, serum iron and transferrin were studied by means of the cosinor method. An evident circadian rhythm was observed for all blood components, except leukocytes. There were no significant differences between patients with dementia senilis and healthy aged persons as far as hematocrit, hemoglobin, erythrocytes, and leukocytes are concerned. Acrophase for serum iron and transferrin occurs a little earlier and mesor is lower than in healthy aged persons.
