Advances in screening instruments for Alzheimer's disease

Area of Science:

• Neuroscience
• Cognitive Psychology
• Gerontology

Background:

• Alzheimer's disease (AD) fundamentally impacts neuroplasticity, specifically disrupting episodic memory.
• Early detection of AD is crucial for timely intervention and management.
• Current cognitive instruments may lack the precision needed for early AD manifestation detection.

Purpose of the Study:

• To review the rationale for early Alzheimer's disease screening.
• To evaluate existing cognitive tools for AD detection.
• To introduce and discuss the MemTrax test as a novel approach for early AD detection and progression monitoring.

Main Methods:

• Literature review on AD, neuroplasticity, and episodic memory.
• Appraisal of current cognitive screening instruments for AD.
• Focus on the development and assessment principles of the MemTrax test.

Main Results:

• Alzheimer's disease significantly impairs neuroplasticity, affecting learning, memory, and cognition, especially episodic memory.
• Existing methods may not precisely capture the subtle, early changes in episodic memory characteristic of AD.
• The MemTrax test assesses neuroplasticity-related metrics relevant to age and AD progression.

Conclusions:

• Early detection of Alzheimer's disease is critical and requires precise measurement tools.
• The MemTrax test shows promise for detecting early AD manifestations and monitoring disease progression.
• Further development of MemTrax could significantly aid in early AD detection and the evaluation of therapeutic interventions.
