The concept of 'brain age', derived from neuroimaging data, serves as a crucial biomarker reflecting cognitive vitality and neurodegenerative trajectories. In the past decade, machine learning (ML) deep (DL) integration has transformed field, providing advanced models for brain age estimation. However, achieving precise prediction across all ages remains significant analytical challenge. This comprehensive review scrutinizes advancements in ML- DL-based prediction, analyzing 52 peer-reviewed studies 2020 to 2024. It assesses various model architectures, highlighting their effectiveness nuances lifespan studies. By comparing ML DL, strengths forecasting methodological limitations are revealed. Finally, key findings reviewed articles summarized number major issues related ML/DL-based discussed. Through this study, we aim at synthesis current state emphasizing both persistent challenges, guiding future research, technological advancements, improving early intervention strategies diseases.

There is a close correlation between brain aging and age. However, traditional neural networks cannot fully capture the potential age due to limited receptive field. Furthermore, they are more concerned with deep spatial semantics, ignoring fact that effective temporal information can enrich representation of low-level semantics. To address these limitations, local attention spatio-temporal graph inference network (LSTGINet) was developed explore details association aging, taking into account both perspectives. First, multi-scale branches used increase field model simultaneously, achieving perception static correlation. Second, feature graphs reconstructed, large topographies constructed. The node aggregation transfer functions hidden dynamic A new module embedded in component global context establish dependencies interactivity different features, balance differences distribution We use newly designed weighted loss function supervise learning entire prediction framework strengthen process final experimental results show MAE on baseline datasets such as CamCAN NKI 6.33 6.28, respectively, better than current state-of-the-art methods, provides basis for assessing state adults.
