The diagnosis of Alzheimer’s disease is clinical–biological. It requires the presence of both a specific clinical phenotype of Alzheimer’s disease (phenotype positive) and biomarker evidence of Alzheimer’s disease pathology (amyloid-positive and tau positive).

May 25, 2023 · The neuropathological changes of Alzheimer's disease (AD) have been shown to commence decades before the onset of symptoms. 1 Accordingly, the ability to non-invasively detect these changes may present opportunities for early diagnosis and intervention.

By incorporating new scientific insights and technological advances, the new guidelines aim to improve current diagnosis, strengthen autopsy reporting of Alzheimer's brain changes, and establish a research agenda for future progress in earlier detection and even greater diagnostic accuracy. Three of the guidelines for research focus on three stages...
Core clinical diagnostic criteria spelled out in the guidelines for Alzheimer's dementia and MCI due to Alzheimer's can be used now in general practice. The guidelines for assessing brain changes during an autopsy can also be used now. The guidelines on preclinical Alzheimer's define this condition as a newly recognized hypothesis on preclinical st...
Biomarkers, such as those sought for Alzheimer's disease, are biological changes in the body that can be reliably measured to indicate the presence or absence of a disease, or the likelihood of later developing a disease. For example, blood glucose levels are a biomarker for diabetes, and blood cholesterol levels are a biomarker for heart disease. ...
Each workgroup initially issued proposed recommendations that were posted here for public comment. The final versions of the guidelines, revised to reflect input from the professional community at large, now appear as free-access papers inAlzheimer's & Dementia®: The Journal of the Alzheimer's Association.

Oct 8, 2021 · The first approval by the US Food and Drug Administration (FDA) of a therapy that is potentially disease-modifying provides a mandate for a specific diagnosis of AD in patients with cognitive impairment and dementia. This topic reviews the clinical manifestations and diagnosis of AD.
Oct 4, 2018 · Abstract. Alzheimer's disease (AD) is a neurodegenerative disorder that accounts for nearly 70% of the more than 46 million dementia cases estimated worldwide. Although there is no cure for AD, early diagnosis and an accurate characterization of the disease progression can improve the quality of life of AD patients and their caregivers.
