Because the biological pathological process is observed decades years before the clinical onset of Alzheimer's disease (AD), there is a theoretical ad-vantage in using biological markers for the early diagnosis of AD. Neuro-psychological test batteries, brain imaging and biological markers are expected to be used for screening and differential diagnosis of dementia and also for evaluation of the efficacy of early intervention.No single biological marker can serve all the purposes of screening, differential diagnosis and measurement of severity. Biological markers that reflect molecular stress, such as oxidative, ribotoxic, and nitroso stress, need to be developed, particularly for measuring the clinical outcomes of interventions. As well as providing a better understanding of the molecular pathogenesis of AD, there is a possibility of finding a surrogate marker of AD, which might fulfill the requirement of sufficient sensitivity and specificity for AD diagnosis, as well as indicating the disease-modifying activity of interventions. In this study we examine whether the mechanism of secretase activity will offer a new surrogate marker of AD.

Abstract. This article explores the possibility of differentiating between patients suffering from Alzheimer’s disease (AD) and patients with other kinds of dementia by focusing on false alarms (FAs) on a picture recognition task (PRT). In Study 1, we compared AD and non-AD patients on the PRT and found that FAs discriminate well between these groups. Study 2 served to improve the discriminatory power of the FA score on the picture recognition task by adding associated pairs. Here, too, the FA score differentiated well between AD and non-AD patients, though the discriminatory power did not improve. The findings suggest that AD patients show a liberal response bias. Taken together, these studies suggest that FAs in picture recognition are of major importance for the clinical diagnosis of AD.

Many problems concerning Alzheimer's disease and Pick's disease are still awaiting clarification. In this country Henderson was the first to draw attention to the considerable importance of Alzheimer's disease in clinical psychiatry. Valuable work has been contributed by various writers in recent years (Grunthal, 1936; Critchley, 1929, 1930, 1931, 1938; Schottky, 1932; Thorpe, 1932; Rothschild, 1934; Malamud, Lowenberg and co-workers, 1929; Mayer-Gross, 1938; Kasanin and Crank, 1933; Jervis and Soltz, 1936; McMenemy, a.o., 1939). While Pick's disease has retained its position as a clinical entity based mainly on the characteristic anatomical picture, the position of Alzheimer's disease in the system of psychiatry has become more complicated; for instance atypical cases have been described presenting the anatomical characters of Alzheimer's disease, though not fitting into the original clinical conception of that disease. Lowenberg and his co-workers (1929) are inclined to regard Alzheimer's disease as a syndrome rather than a clinical entity. Many contributors have directed their main interest to the pathological changes. The knowledge of the symptomatology of those conditions is still incomplete. Further intensive study may enable us not only to base the diagnosis and differential diagnosis of Alzheimer's disease and Pick's disease on more solid clinical knowledge than hitherto, but also to recognize the early stages of those diseases before advancing cerebral degeneration effaces their characteristic clinical features. Unfortunately, most of the cases come under the observation of the psychiatrist only in the later stages of their illness, and it seems that the comparatively small proportion of the mental hospital population they represent does not reflect the incidence of those diseases. It is very likely that many patients die from intercurrent illnesses before their mental condition is recognized or sufficiently advanced to make admission to a mental hospital necessary. The differential diagnosis of those conditions offers considerable difficulties which often may prove insuperable. Alzheimer's disease and Pick's disease have to be distinguished not only from each other but from conditions of vascular origin, from senile dementia and various atypical conditions which occur at the same age period during which Alzheimer's disease and Pick's disease usually develop. Only careful collection and analysis of clinical observations and their scrutiny by pathological investigations can increase our still limited knowledge in this important field of psychiatry.
