The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
* Between 18-80 years of age
* Individuals who know they have an Alzheimer's disease-causing mutation or are unaware of their genetic status and have dominantly inherited Alzheimer's disease (DIAD) mutation in their family.
* Are within -15 to + 10 years of the predicted or actual age of cognitive symptom onset. For Cognitive Run-In (CRI): includes participants who are younger than 15 years prior to the expected age of cognitive symptom onset, in addition to those 15 years younger and no more than 10 years older than expected or actual age of cognitive symptom onset.
* Cognitively normal or with mild cognitive impairment or mild dementia, Clinical Dementia Rating (CDR) of 0-1 (inclusive)
* Fluency in DIAN-TU trial approved language and evidence of adequate premorbid intellectual functioning
* Able to undergo Magnetic Resonance Imaging (MRI), Lumbar Puncture (LP), Positron Emission Tomography (PET), and complete all study related testing and evaluations.
* For women of childbearing potential, if partner is not sterilized, subject must agree to use effective contraceptive measures (hormonal contraception, intra-uterine device, sexual abstinence, barrier method with spermicide).
* Adequate visual and auditory abilities to perform all aspects of the cognitive and functional assessments.
* Has a Study Partner who in the investigator's judgment is able to provide accurate information as to the subject's cognitive and functional abilities, who agrees to provide information at the study visits which require informant input for scale completion.
