[Mild cognitive impairment: diagnostic value of different MR techniques]

Area of Science:

• Neurology and neuroscience
• Medical imaging
• Gerontology

Context:

• Aging populations are increasing dementia prevalence.
• Early diagnosis of dementia and mild cognitive impairment (MCI) is crucial.
• MCI signifies an elevated risk for dementia development.

Purpose:

• To highlight the role of magnetic resonance imaging (MRI) in early dementia diagnosis.
• To explore functional MRI techniques for detecting dementia and MCI.
• To identify advanced MRI methods for differentiating MCI converters from non-converters.

Summary:

• Magnetic resonance imaging (MRI) is vital for early dementia diagnosis, particularly in mild cognitive impairment (MCI).
• Functional MRI techniques, alongside morphological changes, aid in diagnosing dementia and its precursor stages.
• Voxel-based morphometry, MR spectroscopy, and diffusion tensor imaging show promise in predicting dementia risk in MCI patients.

Impact:

• Facilitates timely intervention for individuals with MCI, potentially slowing disease progression.
• Improves diagnostic accuracy for dementia and its early stages.
• Enables personalized risk assessment for MCI patients, guiding clinical management and treatment strategies.
