From: Application of machine learning in measurement of ageing and geriatric diseases: a systematic review
Study | Objectives | Year | Outcome | Number of studies included in the SLR | Findings |
---|---|---|---|---|---|
Choudhury et al. [8] | To understand the current use of AI systems, particularly machine learning (ML), in geriatric clinical care for chronic diseases | 2020 | Individuals over the age of 65 and have one or more chronic illnesses | 35 studies | psychological disorder (n = 22), eye diseases (n = 6), and others (n = 7), and the review identified the lack of standardized ML evaluation metrics and the need for data governance specific to health care applications |
Olender et al. [10] | To examine the role machine learning in predicting clinical outcomes of older adults | 2023 | Older adults above age 65 years | 37 studies | The meta-analysis indicates that machine learning models display good discriminatory power in predicting mortality |
Leghissa et al. [11] | To identify studies based on frailty identification, detection and classification | 2023 | Frail older adults | 41 studies | The data types can be divided into gait data, usually collected with sensors, and medical records, often in the context of aging studies. The most common algorithms are well-known models available from every Machine Learning library |
Chowdhury et al. [9] | To identify the current application of machine learning and artificial intelligence in mental health disorders | 2021 | Studies focusing on electronic health records and administrative health data | 21 articles | Electronic health records was the most used data type, and random forest was the most used ML algorithm |
Baecker et al. [12] | 1. to introduce the reader to the field of brain age prediction and highlight its clinical potential 2. to explain the most common methodological approaches to brain age prediction and discuss five promising clinical applications and possible next steps | 2021 | brain age prediction | – | Five promising clinical applications of ML- 1. Marker of general brain health, 2. Early detection of brain-based disorders, 3. Prognosis of brain-based disorders, 4. Differential diagnosis of brain-based disorders, 5. Treatment outcome Questions and next steps- 1. Account for inter-scanner heterogeneity, 2. Increase granularity of brain age, 3. Dynamic changes of brain age |
Fabris et al. [13] | To review the works that have used supervised ML to study the ageing process | 2017 | supervised machine learning applied to ageing research | – | The link between specific types of DNA repair and ageing; ageing-related proteins tend to be highly connected and seem to play a central role in molecular pathways; ageing/longevity is linked with autophagy and apoptosis, nutrient receptor genes, and copper and iron ion transport |
