Enhancing Alzheimer Disease Detection Using Neuropsychiatric Symptoms: The Role of Mild Behavioural Impairment in the Revised NIA-AA Research Framework
Leon R, Ghahremani M, Guan DX, Smith EE, Zetterberg H, Ismail Z.. Journal of geriatric psychiatry and neurology, 2025-08-13
Topic: Amyloid, tau and blood-test diagnosis
BackgroundAs the prevalence of Alzheimer disease (AD) rises, early identification of at-risk individuals is essential for effective intervention. Mild behavioral impairment (MBI), which captures emergent and persistent neuropsychiatric symptoms (NPS) in later life, may enhance early detection of AD; however, its associations with 2024 NIA-AA Core 1 biomarkers remain unexplored. We investigated associations between MBI and cerebrospinal fluid (CSF) amyloid β-42 (Aβ42) and phosphorylated tau-181 (p-tau181).MethodBaseline data from 1327 dementia-free Alzheimer's Disease Neuroimaging Initiative (ADNI) participants were analyzed.
Key findings
- Mild behavioral impairment (MBI), which captures emergent and persistent neuropsychiatric symptoms (NPS) in later life, may enhance early detection of AD; however, its associations with 2024 NIA-AA Core 1 biomarkers remain unexplored.
- We investigated associations between MBI and cerebrospinal fluid (CSF) amyloid β-42 (Aβ42) and phosphorylated tau-181 (p-tau181).MethodBaseline data from 1327 dementia-free Alzheimer's Disease Neuroimaging Initiative (ADNI) participants were analyzed.
- Participants were classified as MBI, non-MBI NPS, or no NPS.
- Gaussian mixture modeling defined biomarker positivity.
Why it matters
This study looked at whether mild behavioral impairment is linked to Alzheimer's biomarkers in spinal fluid in people without dementia. It is early observational work and does not show that treating these symptoms changes disease course.
