- An extensive new caring program--including the introduction of Individual Care Plans and changes in ward organization, caring techniques, and caring philosophy--was introduced at two psychogeriatric wards with severely demented patients. The hypotheses were that the patients (n = 31) would improve in psychosocial capacity and orientation and the staff work load would decline in contrast to two other wards with a similar clientele (n = 31). After ten months the milieu was more "homelike," routines were more flexible, and the staff communicated more with the patients. However, the hypotheses were not proven. All patients in both groups deteriorated in ADL capacity, orientation, and behavior. The patients in the program wards became significantly more restless and disoriented and ate less than the patients in the contrast wards. The conclusion is that, despite optimal care, a humanistic approach, and support from staff, the progression of dementia symptoms is inevitable.

- A study was made on 150 clinically demented patients presenting at autopsy at Umeå University Hospital in Sweden. In 90 of the cases dementia was considered to be primary in nature and of these forty six per cent (41 cases), fulfilled both the clinical and histopathological criteria for the diagnosis of Alzheimer's disease/Senile dementia of Alzheimer type (AD/SDAT). The families of these 41 AD/SDAT cases were then studied, and a family history obtained through interviews with multiple family informants and from civil and medical records. Additional diseased family members suffering from progressive dementia (multiplex families) were observed in 12 probands out of 41 (29%). Multiplex families exhibited similar clinical and histopathological characteristics as simplex families containing a single affected individual. The secondary cases in the multiplex families exhibited similar demographic and clinical characteristics as the probands. 39% of the multiplex and 14% of the simplex cases had an early age of onset of the disease, that was under 65 years. The overall prevalence of progressive dementia disorders in the 41 families was 5.9%. The prevalence of a progressive dementia disorder was 11% in the multiplex families (14% for the early onset cases) and 3.5% in the simplex families (2% for the early onset cases). The prevalence of progressive dementia disorder for family members who had passed the mean age of the onset of the disease for their family, was 45% for multiplex and 18% for simplex families. Furthermore the incidence rate for dementia was significantly higher (p < 0.005) in multiplex families (5.5 per 1,000 person years) when compared to simplex families (2.5 per 1,000 person years). No differences could be seen in parental age at birth of the diseased when comparing the two sets of families. However in multiplex families the duration of the disease was significantly (p < 0.025) shorter, in subjects with parental age at birth over 35 years compared to those with a parental age under 35 years. The multiplex families contained significantly (p < 0.025) larger sibships; and showed a significantly lower age of onset for the disease (p < 0.001), and a significantly longer duration of disease (p < 0.05) compared to the simplex families. A significant intra familial correlation of age at disease onset was observed in both sets of the families.

- Platelet serotonin (5-hydroxytryptamine, 5-HT) uptake sites were studied in a control group (n = 30) and an Alzheimer group (n = 40) using [3H]paroxetine as radioligand. The maximum number of binding sites (Bmax) for control (1250 +/- 60 fmol/mg protein) was not different from the Alzheimer group (1280 +/- 40 fmol/mg protein). There were no differences in apparent binding affinity (Kd): 0.046 (0.024-0.062) nM for control and 0.040 (0.027-0.061) nM for Alzheimer. Thus even though several previous studies have demonstrated marked atrophy of 5-HT containing neurites and 5-HT uptake sites in Alzheimer's disease, these findings are not found in the periphery on platelets. The platelet 5-HT uptake site cannot be used as a peripheral marker of Alzheimer's disease.
