A systematic review of the Mozart effect in adult and paediatric cases of drug-resistant epilepsy: A sound approach to epilepsy management. Epilepsy Behav 2024; 154:109743. [PMID: 38636110 DOI: 10.1016/j.yebeh.2024.109743] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 02/10/2024] [Accepted: 03/10/2024] [Indexed: 04/20/2024]
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.

Unfounded authority, underpowered studies, and non-transparent reporting perpetuate the Mozart effect myth: a multiverse meta-analysis. Sci Rep 2023; 13:3175. [PMID: 36878928 PMCID: PMC9988829 DOI: 10.1038/s41598-023-30206-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Accepted: 02/17/2023] [Indexed: 03/08/2023] Open
Abstract
In recent years, an ostensible Mozart effect, suggesting beneficial influences of listening to the sonata KV448 on epilepsy, has been extensively covered in popular media outlets. However, the evidential value of such a potential effect seems unclear. Here, we present the first formal meta-analysis on this topic, based on k = 8 studies (N = 207). Further published studies that met our inclusion criteria had to be omitted due to insufficient reporting and author non-responsiveness on data requests. In three independent analyses, we observed non-significant trivial-to-small summary effects for listening to Mozart KV448 or other musical stimuli on epilepsy or other medical conditions (g range: 0.09-0.43). Bias and sensitivity analyses suggested that these effects were likely inflated and non-trivial effects were driven by isolated leverage points. Multiverse analyses conformed to these results, showing inconsistent evidential patterns. Low primary study power and consequently lacking evidential value indicates that there is only little reason to suspect a specific Mozart effect. In all, listening to music, let alone a specific kind of sonata, does not appear to have any beneficial effect on epilepsy. Unfounded authority, underpowered studies, and non-transparent reporting appear to be the main drivers of the Mozart effect myth.

Abstract
Abstract
Objective
To review the current literature on the practice of intramuscular injections (IMIs), focusing on immunizations.
Methods
The present study comprises 2 reviews, characterized by high-quality evidence, pertaining to the deployment of the slow injection technique without aspiration (referred to in this paper as the without-aspiration slow injection technique [WASiT]) and combined with the Zeta-track technique (ZTT). The literature review is oriented toward the analysis of 2 features associated with IMIs techniques: safety and pain, integrating new evidence on vaccinee positioning for each muscle site and general relaxation techniques in the multi-parametric analysis.
Results
The rigorous and in-depth reviews in the current study reveal the usefulness of including, among the international guidelines for via intramuscular immunizations, the adoption of WASiT only for compliant vaccinees, and in combination with all validated techniques for IMIs, and the use of ZTT limitedly if specific well-developed muscles are indicated. All the technique’s limitations are exposed.
Conclusions
Future research directions are presented by including the author’s study designs to provide indirect evidence for the validity of the rationale of the slow injection technique using scientific methods, and for the conduction of future randomized controlled trials (RCTs) focused on revisiting the adoption of ZTT in a dynamic and integrated immunizations protocol in anterolateral thigh (ALT), ventrogluteal (VG), and also in the deltoid muscle, in the specific cases analyzed.

Abstract
Sound waves are all around us resonating at audible and inaudible frequencies. Our ability to hear is crucial in providing information and enabling interaction with our environment. The human brain generates neural oscillations or brainwaves through synchronised electrical impulses. In epilepsy these brainwaves can change and form rhythmic bursts of abnormal activity outwardly appearing as seizures. When two waveforms meet, they can superimpose onto one another forming constructive, destructive or mixed interference. The effects of audible soundwaves on epileptic brainwaves has been largely explored with music. The Mozart Sonata for Two Pianos in D major, K. 448 has been examined in a number of studies where significant clinical and methodological heterogeneity exists. These studies report variable reductions in seizures and interictal epileptiform discharges. Treatment effects of Mozart Piano Sonata in C Major, K.545 and other composer interventions have been examined with some musical exposures, for example Hayden's Symphony No. 94 appearing pro-epileptic. The underlying anti-epileptic mechanism of Mozart music is currently unknown, but interesting research is moving away from dopamine reward system theories to computational analysis of specific auditory parameters. In the last decade several studies have examined inaudible low intensity focused ultrasound as a neuro-modulatory intervention in focal epilepsy. Whilst acute and chronic epilepsy rodent model studies have consistently demonstrated an anti-epileptic treatment effect this is yet to be reported within large scale human trials. Inaudible infrasound is of concern since at present there are no reported studies on the effects of exposure to infrasound on epilepsy. Understanding the impact of infrasound on epilepsy is critical in an era where sustainable energies are likely to increase exposure.

Abstract
Understanding the neural correlates of perception of hierarchical structure in music presents a direct window into auditory organization. To examine the hypothesis that high-level and low-level structures—i.e. phrases and notes—elicit different neural responses, we collected intracranial electroencephalography (iEEG) data from eight subjects during exposure to Mozart’s K448 and directly compared Event-related potentials (ERPs) due to note onsets and those elicited by phrase boundaries. Cluster-level permutation tests revealed that note-onset-related ERPs and phrase-boundary-related ERPs were significantly different at \documentclass[12pt]{minimal}

We relate these observations to (1) a process which syntactically binds notes together hierarchically to form larger phrases; (2) positive emotions induced by successful prediction of forthcoming phrase boundaries and violations of melodic expectations at phrase boundaries.

Abstract
Music is an art form that strongly affects people and can elicit many different emotions at the same time, including happiness, anxiety, sadness, and even ecstasy. What is it about music that causes such a strong reaction from each of us? Music engages many senses, which in turn can produce a multiplicity of responses and help create more extensive neuronal connections, as well as influence behaviour through structural and functional changes in the brain. Music-based interventions as a therapeutic tool in rehabilitation are becoming more common. It is said that the impact of music on the human body is positive. However, what impact does music have on the young nervous system, especially the affected one? This review presents the advantages and disadvantages of the use of music in paediatric neurology to treat dyslexia, cerebral palsy, and stroke, among others. Potential negative impacts such as musicogenic epilepsy and hallucinations will be discussed.

Abstract
INTRODUCTION Antiseizure medications (ASMs) are the primary treatment option for epilepsies of wide etiologies, however, about 10-20% of children do not gain sustained seizure control and in this case, it is worth investigating "alternative" therapeutic approaches aside from ASMs. Nowadays, non-pharmacological strategies for epilepsy treatment encompass dietary interventions, neurostimulation-based techniques, and biobehavioral approaches. AREAS COVERED A search on PubMed database was conducted. Experimental and clinical studies, as well as meta-analysis and structured reviews on the latest non-pharmacological treatments for drug-resistant epilepsy (DRE) in children, were included. Special attention is given to the efficacy and tolerability outcomes, trying to infer the role novel approaches may have in the future. EXPERT OPINION The large heterogeneity of primary clinical outcomes and the unavoidable subjective response of each patient to treatments prevents Researchers from the identification of a single, reliable, approach to treat DRE. The understanding of fine pathophysiologic processes is giving the way to the use of alternative therapies, such as the well-known ketogenic diet, in a "personalized" view of treatment. The goal is to apply the non-pharmacological treatment most suitable for the patient's sake.

Musical components important for the Mozart K448 effect in epilepsy. Sci Rep 2021; 11:16490.

Abstract
There is growing evidence for the efficacy of music, specifically Mozart’s Sonata for Two Pianos in D Major (K448), at reducing ictal and interictal epileptiform activity. Nonetheless, little is known about the mechanism underlying this beneficial “Mozart K448 effect” for persons with epilepsy. Here, we measured the influence that K448 had on intracranial interictal epileptiform discharges (IEDs) in sixteen subjects undergoing intracranial monitoring for refractory focal epilepsy. We found reduced IEDs during the original version of K448 after at least 30-s of exposure. Nonsignificant IED rate reductions were witnessed in all brain regions apart from the bilateral frontal cortices, where we observed increased frontal theta power during transitions from prolonged musical segments. All other presented musical stimuli were associated with nonsignificant IED alterations. These results suggest that the “Mozart K448 effect” is dependent on the duration of exposure and may preferentially modulate activity in frontal emotional networks, providing insight into the mechanism underlying this response. Our findings encourage the continued evaluation of Mozart’s K448 as a noninvasive, non-pharmacological intervention for refractory epilepsy.

40-Hz auditory stimulation for intracranial interictal activity: A pilot study. Acta Neurol Scand 2021; 144:192-201. [PMID: 33893999 DOI: 10.1111/ane.13437] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Revised: 03/08/2021] [Accepted: 04/11/2021] [Indexed: 12/13/2022]
Abstract
OBJECTIVES To study the effects of auditory stimuli on interictal epileptiform discharge (IED) rates evident with intracranial monitoring. MATERIALS AND METHODS Eight subjects undergoing intracranial EEG monitoring for refractory epilepsy participated in this study. Auditory stimuli consisted of a 40-Hz tone, a 440-Hz tone modulated by a 40-Hz sinusoid, Mozart's Sonata for Two Pianos in D Major (K448), and K448 modulated by a 40-Hz sinusoid (modK448). Subjects were stratified into high- and low-IED rate groups defined by baseline IED rates. Subject-level analyses identified individual responses to auditory stimuli, discerned specific brain regions with significant reductions in IED rates, and examined the influence auditory stimuli had on whole-brain sigma power (12-16 Hz). RESULTS All subjects in the high baseline IED group had a significant 35.25% average reduction in IEDs during the 40-Hz tone; subject-level reductions localized to mesial and lateral temporal regions. Exposure to Mozart K448 showed significant yet less homogeneous responses. A post hoc analysis demonstrated two of the four subjects with positive IED responses had increased whole-brain power at the sigma frequency band during 40-Hz stimulation. CONCLUSIONS Our study is the first to evaluate the relationship between 40-Hz auditory stimulation and IED rates in refractory epilepsy. We reveal that 40-Hz auditory stimuli may be a noninvasive adjunctive intervention to reduce IED burden. Our pilot study supports the future examination of 40-Hz auditory stimuli in a larger population of subjects with high baseline IED rates.

Long-term music adjuvant therapy enhances the efficacy of sub-dose antiepileptic drugs in temporal lobe epilepsy. CNS Neurosci Ther 2021; 28:206-217.

Abstract
Aims Noninvasive music adjuvant therapy shows great potential in improving seizure control when combined with routine antiepileptic drugs. However, the diversity of previous music protocols has resulted in disparate outcomes. The optimized protocol and features for music adjuvant therapy are still not fully understood which limits its feasibility. Methods By applying different regimens of music therapy in various temporal lobe epilepsy models, we evaluated the effect of music in combination with sub‐dose drugs on epileptic seizures to determine the optimized protocol. Results A subgroup of kindled mice that were responsive to music adjuvant therapy was screened. In those mice, sub‐dose drugs which were noneffective on kindled seizures, alleviated seizure severity after 12 h/day Mozart K.448 for 14 days. Shorter durations of music therapy (2 and 6 h/day) were ineffective. Furthermore, only full‐length Mozart K.448, not its episodes or other music varieties, was capable of enhancing the efficacy of sub‐dose drugs. This music therapeutic effect was not due to increasing cerebral drug concentration, but instead was related with the modulation of seizure electroencephalogram (EEG) spectral powers in the hippocampus. Conclusion These results indicate that long‐term full‐length Mozart K.448 could enhance the anti‐seizure efficacy of sub‐dose drugs and may be a promising noninvasive adjuvant therapy for temporal lobe epilepsy.

Effect of Mozart K.448 on interictal epileptiform discharges in children with epilepsy: A randomized controlled pilot study. Epilepsy Behav 2021; 114:107177.

Abstract
BACKGROUND Epilepsy is a common pediatric neurologic disease in Thailand. However, the mainstay antiepileptic pharmacotherapies can induce severe side effects. While the benefit of playing Mozart K.448 music has been studied as an alternative, supplementary, nonpharmacologic treatment for epilepsy, the literature features limited few randomized controlled trial studies of children. OBJECTIVE We aimed to study the effect of Mozart K.448 for two pianos on interictal epileptiform discharges (IEDs), quantitative electroencephalogram (qEEG), and heart rate variability (HRV) in patients with epilepsy. METHODS We employed a single-blinded randomized trial design with a placebo control. The treatment group listened to the first 8 min of Mozart K.448 for two pianos during EEG recording. The control group underwent an EEG recording of the same duration in a quiet environment. Interictal epileptiform discharges were manually counted for 8 min before, during, and after the song was plated. Quantitative electroencephalogram and HRV were analyzed in each period. RESULT A total of 32 patients aged 0-18 years were enrolled. There were 12 patients in the music group and 14 patients in the control group; 67% of the patients in the former exhibited significantly decreased IEDs while listening to the music compared with 42% of the patients in the quiet group (RR [Relative Risk Reduction]: 0.72, p-value: <0.001, 95% confidence interval [CI]: 0.69-0.74). During music exposure, qEEG demonstrated an increase in the delta/theta to alpha/beta ratio relative to that of controls (median in music: +3% and control: -6%, p-value: 0.520). Heart rate variability analyses showed a decrease in the ratio of low frequency to high frequency (LF/HF), which represents parasympathetic activity during music exposure (decrease of 34%, p-value: 0.382). CONCLUSION The present study showed that Mozart K.448 reduced the number of IEDs in children with epilepsy and that Mozart K.448 could enhance parasympathetic activity. However, possibly because of the small study population, statistical significance was not reached. Our study revealed the considerable potential of music in the treatment of pediatric epilepsy.

Abstract
PURPOSE OF REVIEW Despite the increase in the number of novel antiseizure medications over the past 20 years, approximately one-third of patients will not have adequate seizure control on medications. For these patients, additional options need to be considered, including dietary, device, and surgical treatments. In addition, many complementary therapies can be considered as adjunctive treatment, with the intent of improving quality of life for persons with epilepsy and potentially allowing for improvement in seizure control. RECENT FINDINGS This review outlines established and developing treatments for drug-resistant epilepsy. Surgical treatments, including resective surgery and vagus nerve stimulation, have been routine care for several decades. In the last several years, new neurostimulation options have been approved (responsive neurostimulation and deep brain stimulation) or are under development (continuous subthreshold cortical stimulation). For patients with lesion or well-defined seizure-onset zones, less invasive options including laser ablation and ultrasound therapy provide the potential for faster recovery times and less morbidity. Not all therapies are in the pharmacological or surgical arenas. This review also explores the evidence for complementary treatments, including relaxation and meditation techniques, and art and music therapy. Despite the range of antiseizure medications available, they still provide inadequate for a large number of patients with epilepsy, either due to ongoing seizures or intolerable side effects. Complementary therapies, including diet, meditation techniques, and music therapy, provide compelling treatment options to improve quality of life while potentially improving seizure control. In appropriate patients, stimulation devices or surgical resection can offer options for significant seizure reduction or even cure. The full range of therapeutics should be considered for each patient with epilepsy when they are struggling with inadequate seizure control or side effects with traditional pharmacological treatment.

Non-pharmacological Interventions for Intractable Epilepsy. Saudi Pharm J 2020; 28:951-962.

Abstract
In 30% of epileptic individuals, intractable epilepsy represents a problem for the management of seizures and severely affects the patient's quality of life due to pharmacoresistance with commonly used antiseizure drugs (ASDs). Surgery is not the best option for all resistant patients due to its post-surgical consequences. Therefore, several alternative or complementary therapies have scientifically proven significant therapeutic potential for the management of seizures in intractable epilepsy patients with seizure-free occurrences. Various non-pharmacological interventions include metabolic therapy, brain stimulation therapy, and complementary therapy. Metabolic therapy works out by altering the energy metabolites and include the ketogenic diets (KD) (that is restricted in carbohydrates and mimics the metabolic state of the body as produced during fasting and exerts its antiepileptic effect) and anaplerotic diet (which revives the level of TCA cycle intermediates and this is responsible for its effect). Neuromodulation therapy includes vagus nerve stimulation (VNS), responsive neurostimulation therapy (RNS) and transcranial magnetic stimulation therapy (TMS). Complementary therapies such as biofeedback and music therapy have demonstrated promising results in pharmacoresistant epilepsies. The current emphasis of the review article is to explore the different integrated mechanisms of various treatments for adequate seizure control, and their limitations, and supportive pieces of evidence that show the efficacy and tolerability of these non-pharmacological options.

Abstract
OBJECTIVE The use of music-based neuro-stimulation for treating seizures and interictal epileptiform discharges (IED) (the so-called "Mozart effect") remains a controversial issue. We have conducted an updated meta-analysis in order to systematically review literature evidence and provide further insights about the role of the Mozart effect in epilepsy. METHODS Following the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" (PRISMA) guidelines, we searched three bibliographic databases from their date of inception to January 2020. Nine meta-analyses were performed according to both music stimulation protocols and outcome measures. We applied the Cochrane Q-test and the I2-index for heterogeneity evaluation, and either fixed-effect or random-effect models to compute mean differences and pool data. RESULTS Of 147 abstracts, 12 studies were included and grouped according to stimulation protocols and outcome measures. The nine meta-analyses showed significant reductions in seizures and IED frequencies after long-term music treatment, and in IED frequency during and after a single music stimulus. CONCLUSIONS Music-based neurostimulation may improve the clinical outcome of individuals with epilepsy, by reducing the frequency of seizures and IED. Further and stronger evidence will allow defining its potential in the different forms of epilepsy, and the most effective stimulation protocols. SIGNIFICANCE Music therapy should be considered as a complementary, non-invasive approach for treating epilepsy and epileptiform discharges.

Abstract
Introduction & objectives: Although controversial, the Mozart effect, consisting of an improvement in cognitive abilities in healthy persons, has started to be studied in the case of patients with various neurological, even neurodegenerative diseases (dementia, treatment-refractory epilepsy). There are few data on the Mozart effect in Parkinson’s disease, but the positive results reported for other neurological pathologies have led us to study this subject. The aim of this study is to compare the results of the Mozart effect associated with specific kinetic treatment in the rehabilitation of Parkinson’s disease and the effect of standard kinesiotherapy, results reflected in the impact on the degree of disability, emotional state and quality of life.
Material and method: This was a prospective case-control study, comprising patients with Parkinson’s disease, Hoehn & Yahr stages I-III, included in a motor neurorehabilitation program through the project “The power of hope for patients with Parkinson’s disease” Cluj-Napoca. The patients were assigned to two groups, a control group with specific physiotherapy and the other group receiving the same specific kinetic treatment associated with the Mozart effect, for 2 hours daily, over 14 consecutive days. The patients were assessed using the Schwab & England scale (for the degree of dependence) and the PHQ-9 scale (for depression) before and after therapy.
Results: After 2 weeks of therapy, the patients in the study group had much more obvious, statistically significant improvements in both scores.
Conclusions: Mozart’s music, as an adjuvant intervention to specific kinetic treatment in patients with Parkinson’s disease, had a beneficial effect, ameliorating the degree of disability and emotional status.
