Brief Summary
The aim of this study is to find out whether a new image analysis technique called Cortical Disarray Measurement (CDM) could be used to help better diagnose Alzheimer's disease. This study will see whether changes on CDM can be used to identify Alzheimer's disease from a group of people living with memory and thinking problems. The study will also explore how CDM relates to changes in memory or thinking over time.

Outcome Measures
Primary Outcomes (1)
CDR Progression
CDR Progression defined as a binary variable (yes/no) indicating either an increase in global outcome on Clinical Dementia Rating (CDR) scale (which takes value 0, 0.5, 1, 2 or 3, with higher scores reflecting more severe dementia), or an increase greater than, or equal to, 2 points on CDR Sum of Boxes (which takes values from 0 to 18 with higher values indicating a worse outcome)
Baseline (Study day 1) to month 24

Patient Participants
Patient participants will have a diagnosis of mild cognitive impairment or prodromal / mild Alzheimer's Disease. Participants with a global CDR score of 0.5 and 1 will be recruited in a minimum of a 2:1 ratio respectively in the study.
Study Companions
Study companions will have sufficient knowledge on the patient participant's condition to complete companion assessments of the patient, in the investigator's judgement, for example they may be carers of the patients.
Eligibility Criteria
A total of 200 patient participants and 200 study companions will be recruited to the study. Patient participants will have a diagnosis of mild cognitive impairment or prodromal / mild Alzheimer's Disease. Participants with a global CDR score of 0.5 and 1 will be recruited in a minimum of a 2:1 ratio respectively in the study.
You may qualify if:
- Diagnosis of mild cognitive impairment (MCI) or prodromal Alzheimer's Disease (AD) as defined by National Institute on Ageing/Alzheimer's Association (NIA/AA) diagnostic criteria for MCI/prodromal AD, NOT including MCI unlikely due to AD; OR, Diagnosis of Alzheimer's disease as defined by NIA/AA criteria for probable AD
- Clinical dementia rating (CDR) scale global score of very mild or mild (0.5 or 1) impairment
- Ability to undergo and tolerate MRI scans, with no contraindications to MRI
- Ability to tolerate blood draws
- Ability to give informed consent to participate in the study
You may not qualify if:
- No study companion available
- Individuals with a non-progressive learning disability
- Pregnant or intending to become pregnant during the study
- COMPANION PARTICIPANTS
- Aged over 18 years
- Sufficient knowledge on study participant's condition to complete companion assessments of the patient, in the investigator's judgement
- Able and willing to attend all clinical visits for completion of companion assessments or provide the relevant assessments remotely via phone or video call
- A condition or reason, in the investigator's judgement, that would question the validity of the acquired companion reported data
- Individuals who are not fluent in English

Biospecimen
Participants recruited will be invited to join a biosample repository substudy. This is an optional component to the main study that involves the collection and storage of biosamples for analysis of potential biomarkers of Alzheimer's disease and neurodegeneration, to aid validation of the CDM technique, and for future health research.
