Dementia

Dementia

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual....

Background:

Dementia presents progressive cognitive decline, posing challenges in elderly care.
Fluctuating cognitive function necessitates timely assessment for effective dementia care and rehabilitation.
Current assessment methods may not fully capture dynamic cognitive changes in dementia patients.

Purpose of the Study:

To introduce a novel quantification method for assessing cognitive function changes in dementia patients.
To utilize Internet of Things (IoT) sensors for gathering behavioral data relevant to cognitive status.
To evaluate the efficacy of the proposed method in tracking cognitive performance, particularly memory abilities.

Main Methods:

Deployment of IoT sensors to collect continuous behavioral data, including gait and sleeping patterns.
Development of a quantification approach to analyze the collected behavioral data.
Application of the quantification method to assess cognitive function changes over time.

Main Results:

The IoT sensor-based quantification method successfully analyzed behavioral data.
The proposed approach demonstrated the ability to assess cognitive performance changes.
Significant correlations were observed with memory-related abilities, specifically registration and recall.

Conclusions:

IoT sensors and a novel quantification method offer a promising approach for monitoring cognitive changes in dementia.
This technology can aid caregivers in timely assessment, leading to improved dementia care and rehabilitation strategies.
The method shows potential for objective evaluation of memory functions in elderly individuals with dementia.
