Activities of daily living and global functioning

Area of Science:

• Gerontology and Neurology
• Public Health and Aging

Background:

• Disability is a significant consequence of aging, impacting individuals, families, and society, and incurring substantial social system costs.
• Understanding the causes of pathological processes leading to disability and identifying early (preclinical) stages are essential for prevention and delay.
• Vascular dementia presents unique challenges in disability patterns and severity compared to other dementia forms.

Purpose of the Study:

• To highlight the importance of identifying preclinical disability in the elderly.
• To emphasize the role of vascular cognitive impairment in preclinical disability.
• To advocate for the development and validation of sensitive instruments for assessing global function in early-stage cognitive impairment.

Main Methods:

• Literature review on aging, disability, and dementia.
• Analysis of the characteristics of vascular cognitive impairment in relation to preclinical disability.
• Discussion on the need for specialized assessment tools.

Main Results:

• Vascular cognitive impairment can represent a preclinical disability state.
• Subtle cognitive deficits, particularly in executive functions, may occur without significant impact on daily activities.
• Current assessment tools may not be sufficiently sensitive to detect these early changes.

Conclusions:

• Early identification of preclinical disability, especially linked to vascular cognitive impairment, is critical for effective aging health strategies.
• Targeted interventions can be developed if sensitive measures are available to detect subtle cognitive declines.
• Further research and development of validated instruments are needed to comprehensively assess global function in preclinical disability stages.
