Plasma concentrations of vitamins A and E and carotenoids in Alzheimer's disease.

In a case/control study, serum concentrations of vitamins A and E and major carotenoids were determined in patients with Alzheimer's disease, multi-infarct dementia and control subjects. The results showed that both Alzheimer's and multi-infarct dementia patients had significantly lower levels of vitamin E and beta-carotene than controls (vitamin E: 18.65 +/- 3.62 mumol/l in Alzheimer's disease and 15.80 +/- 6.93 mumol/l in multi-infarct dementia versus 30.03 +/- 12.03 mumol/l in controls; beta-carotene less than 0.13 to 0.42 mumol/l in Alzheimer's disease and less than 0.13 to 0.30 mumol/l in multi-infarct dementia versus 0.13 to 1.53 mumol/l in controls). Vitamin A was significantly reduced only in the Alzheimer's patients (1.56 +/- 0.78 mumol/l in Alzheimer's disease versus 2.13 +/- 0.86 mumol/l in controls).

Drug prescribing in the elderly.

Napoleon I (1769-1821) said: "I do not wish two diseases, one nature made and one man made." In no other area of medical practice is this more apt than in that concerned with the care of the elderly. The dangers of inappropriate drug prescribing are heightened in the elderly for a number of reasons related to certain patterns of illness in this age group.

Tuberculous meningitis in the elderly.

Six cases of tuberculous meningitis, all occurring in patients over the age of 65, are described. All patients presented with an acute illness, primarily with a confusional state. Headache was a symptom in only two patients and the cases were not confined to ethnic minority groups. The mortality was 50%.

Is "T4 toxicosis" a normal biochemical finding in elderly women?

The lack of equivalence in the distrubtion of normal ranges for free thyroxine index (FT4I) and free triiodothyronine index (FT3I) in the over sixty-five age-group, as compared with the fifteen-sixty-five age-group, supports the idea that "T4 toxicosis" is a common biochemical finding in elderly women. The disparity between FT4I and FT3I ranges was also reflected in the true free T4 and free T3 levels which were measured in some cases. These results suggest that when an increased FT4I is found in an elderly woman with cardiac disease, caution should be exercised in interpreting the result as indicating that thyrotoxicosis is the cause of the cardiac disorder. Estimation of total T3, FT3I, or free T3 seems useful in confirming euthyroidism in such cases.
