NCT ID NCT06120361
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to make it easier for family doctors to detect early signs of Alzheimer's and other dementias. Researchers will test 1,200 adults with memory or thinking problems using blood tests and brain scans. The goal is to see if these tools can accurately identify who has Alzheimer's disease, helping doctors refer patients to specialists sooner and improve care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to simpler, faster, and more accurate diagnosis of Alzheimer's disease in regular doctor's offices, helping patients get the right care sooner.
- What could go wrong
- This is an observational study, not a treatment trial. The blood tests are still being validated and may not be accurate enough for widespread use. Results may not apply to all populations.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The investigators will consecutively recruit 1200 patients seeking medical care due to mild cognitive symptoms in primary care units. They will be recruited at approximately 20-30 primary care facilities in Skåne. The patients will as usual first meet a general practitioner who performs a basic investigation of the patient to rule out other obvious causes causing the cognitive symptoms other than a dementia disorder, such as depression, sleep deprivation, etc. The patients, whose cognitive symptoms are not clearly explained by psychiatric or somatic conditions, will be assessed with cognitive tests by a dementia nurse or occupational therapist at the primary care unit.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. The patient seeks medical help because of cognitive symptoms experienced by the patient and/or informant OR The general practitioner suspects a progressive neurodegenerative disorder including, but not limited to, Alzheimer's disease, Lewy body disease, frontotemporal lobar degeneration or subcortical vascular cognitive impairment. 2. The main symptom is usually memory complaints, but could also be executive, visuo-spatial, language, or attention complaints. 3. Age ≥40 years 4. Subjective cognitive decline, mild cognitive impairment or mild dementia Exclusion Criteria: 1. Already diagnosed dementia 2. Significant unstable systemic illness or organ failure that makes it difficult to participate. 3. Current significant alcohol or substance misuse. 4. Refusing investigation at the Memory clinic 5. Cognitive impairment with acute onset due to stroke 6. The cognitive impairment can with certainty be explained by another condition or disease such as significant anemia, infection, severe sleep deprivation, psychotic disorder, moderate-severe depression, alcohol abuse etc.
