Integrating music-based interventions with Gamma-frequency stimulation: Implications for healthy ageing

Area of Science:

• Neuroscience
• Gerontology
• Cognitive Science

Background:

• Music-based interventions (MBIs) are popular non-invasive treatments for dementia-related disorders, including Mild Cognitive Impairment (MCI) and Alzheimer's disease (AD).
• Evidence for the efficacy of MBIs in improving patient outcomes remains mixed.
• Emerging research explores non-invasive Gamma-frequency (e.g., 40 Hz) sensory stimulation for dementia.

Purpose of the Study:

• To propose a novel clinical framework combining MBIs with Gamma-frequency stimulation for treating dementia-related disorders.
• To theorize how this combined approach may enhance therapeutic outcomes.
• To explore the potential of this integrated framework in addressing multiple dementia biomarkers and neural pathways.

Main Methods:

• This review synthesizes existing research on MBIs and Gamma-frequency stimulation in dementia.
• It proposes a theoretical framework integrating these two approaches.
• The framework focuses on enhancing neural activity and engaging specific brain networks.

Main Results:

• Non-human animal models suggest Gamma-frequency stimulation can ameliorate dementia pathologies and improve cognition.
• Combining MBIs with Gamma-frequency stimulation is hypothesized to enhance therapeutic effects.
• This integrated approach may target multiple dementia biomarkers and restore neural activity crucial for memory.

Conclusions:

• A novel framework combining MBIs and Gamma-frequency stimulation is proposed for non-invasive dementia treatment.
• This synergistic approach holds potential for enhancing cognitive function and addressing dementia pathophysiology.
• Further clinical research is warranted to validate the efficacy of this combined intervention.
