Abstract

Objectives In recent years, adjunctive therapies for epilepsy management are being explored due to considerable side effects carried by antiepileptic drugs (AEDs) and widespread reports of drug-resistant epilepsy. One such approach is non-invasive musical neurostimulation. Within this context, Mozart’s sonata K448 has received particular attention following reports of reduced seizure frequency and a decrease in epileptiform discharges during and after music exposure; often described as the ‘Mozart effect’. However, controversy exists around the effectiveness of K448 in epilepsy and the strength and quality of the evidence supporting it. Therefore, this study aims to systematically review the available literature around the Mozart effect, in both adult and paediatric cases of epilepsy. Methods We carried out a literature search on PubMed, Science Direct, Scopus and Web of Science using the query string ALL= (Mozart AND epileps*). Selected clinical studies were classified based on the age of the population studied, as paediatric (0–18 years), adult (19 years or older) or a combination of the two. All the studies were evaluated using the Johns Hopkins Nursing Evidence-Based Practice (JHNEBP) rating scale to determine the strength of the evidence (level) and the quality of the research evidence. Results Out of 538 records, 25 studies were selected, grouped based on the age of the population studied and evaluated using the JHNEBP rating scale. Ten level 1 studies, which represent the strongest evidence, were identified, including six RCTs and three meta-analyses. Nine of these ten studies show a decrease in epileptiform discharges and in seizure frequency following exposure to Mozart’s K448. One multiverse analysis reported lack of statistically significant evidence to support the use of K448 in epilepsy or any other medical condition. Conclusions A growing body of evidence supports the Mozart effect on epilepsy, with notable studies including RCTs and comprehensive meta-analyses. This review identified nine level 1 studies, conducted by research groups worldwide, which endorse the use of Mozart's music to reduce seizures and epileptiform discharges in adult and paediatric epilepsy patients. However, existing research exhibits limitations like varying protocols, small sample sizes and diverse treatment regimens. Additionally, studies that combine adult and paediatric patients fail to take account of developmental differences between these two groups – particularly with regards to brain maturation and neurophysiology – which could negatively impact upon the accuracy of findings by obscuring important age-related differences in response to intervention. Adequately addressing these limitations will be crucial to demonstrating proof of concept; otherwise, a potentially valuable, non-invasive, accessible, and affordable therapeutic option for drug-resistant epilepsy will remain on the medical fringe. Further research with larger samples and stricter protocols, particularly considering patient age and drug regimens, is required.
