Variation in quarter of birth was examined in patients with a clinical diagnosis of AD. There was a significant excess of first-quarter births among AD patients as compared with the expected birth rates derived from an age-matched census sample. This finding was due entirely to the significant excess of first-quarter births in AD patients without a family history of dementia. No seasonal variation was found in the birth dates of other clinical groups.

Birth Data

We obtained season-of-birth data in 727 autopsy-confirmed cases of Alzheimer's Disease (AD) and compared these data with expected general population birth rates. There were no significant differences between quarterly birth rates in the AD group and expected quarterly birth rates. Edward's test for cyclical trends did not establish a peak period of birth in the AD sample. No significant differences between observed and expected quarterly birth rates were found when data were analyzed with regard to either family history of dementia or to gender. Edward's test for peak quarter was significant for AD females, however, with the peak period occurring early in the first quarter. These negative findings between observed and expected quarterly birth rates, based on the large number of autopsy-confirmed AD cases in this study, suggest that a season-of-birth effect in AD is highly unlikely.

Abstract:A potential relationship between Alzheimer's Disease (AD) and insulin gene expression was suggested by the observation that patients with AD have altered levels of fasting blood sugar and insulin. Since polymorphisms in the region 5' to the insulin gene have been associated with blood glucose levels, we have studied this polymorphism in AD patients. Subjects were 19 nondiabetic AD patients with symptoms of aphasia and apraxia and a family history of AD; and 20 age and sex-matched nondiabetic controls without family history of AD. The 5' polymorphic region of the insulin gene was analyzed by restriction enzyme digestion of DNA extracted from whole venous blood. We did not observe a correlation between the size of the 5' polymorphic region and AD.

Abstract Understanding individual factors (e.g., personality) associated with self-reported memory problems is important to refine identification of individuals at a higher risk of developing Alzheimer’s disease (AD). Using multilevel modeling, we examined the association of family history of AD and personality traits with self-reported memory problems in older adults (n = 421; 72.21% White; 62.95% female; Mage = 76.69). Results showed that individuals with a family history of AD reported more frequent memory problems and greater one-year memory decline. Similar findings were reported for individuals with higher extraversion scores. Further, older adults with higher neuroticism scores reported greater one- and ten-year memory decline. Neuroticism was positively related to frequency of memory problems, but only among participants with a family history of AD. Findings suggest that higher neuroticism and lower extraversion may increase older adults’ reports of memory problems. Family history of AD may further exacerbate this tendency.
