Descripción

DELCODE is conducted by DZNE, the German Center for Neurodegenerative Diseases within the Helmholtz Association. The following information was taken from https://www.dzne.de/en/research/studies/clinical-studies/delcode/. Background and aims: One of the important aims of research into Alzheimer's is to find ways of detecting the disease early – if at all possible, as soon as the first minor symptoms appear, or even before any symptoms at all have appeared. Such detection capabilities are the necessary basis for development of therapies that can be applied at such early stages in the disease. Recent research indicates that such therapies could be more effective than therapies initiated during the disease's later stages. Over a period of several years, the DELCODE study is studying persons in early stages of the disease, along with various risk groups. The research is aimed at the development of procedures for characterizing early stages of the disease, at improving prediction of the course of the disease and at identifying new markers for early diagnosis of Alzheimer's-related dementia. Overview: DELCODE is set up to run for an initial period of three years, and to include a total of 1,000 study participants, who will be examined on a yearly basis. The group of participants will include persons with no complaints (healthy control subjects), patients with slight memory impairment or mild dementia and first-degree relatives of patients with diagnosed Alzheimer's disease. The minimum age for participants is 60. Course of the study: The examinations in the framework of the study will include a comprehensive interview carried out by a study investigator, a detailed neuropsychological examination (testing of memory functions and other areas of cognitive performance), a blood test and a cranial MRI scan. Optionally, subject to the study participant's consent in each case, a lumbar puncture (collection of cerebrospinal fluid) will be carried out."

This document contains the Geriatric Depression Scale (GDS) and the Geriatric Anxiety Inventory – Short Form (GAI‐SF). It has to be filled in for Baseline and for all Follow-ups. For use of the questionnaire GDS no licence is required. For more information to the GDS see Yesavage JA, Brink TL, Rose TL, Lum O, Huang V, Adey M, Leirer VO. Development and validation of a geriatric depression screening scale: a preliminary report. J Psychiatr Res. 1982-83;17(1):37-49. Due to potential copyright on the questionnaire GAI-SF included in the DZNE DELCODE protocol, GAI-SF will only be included as text result item in this version of the DELCODE forms (at least until permission to publish is received from the original authors or becomes clear upon further research). The respective score items will have a comment in their descriptions about this to distinguish them from score items that were already defined like that by DZNE.
