The Effect of Mozart's Music in Severe Epilepsy: Functional and Morphological Features.

Music is a very important factor in everyday life, involving mood, emotions and memories. The effect of music on the brain is very debated. Certainly, music activates a complex network of neurones in auditory areas, mesolimbic areas, cerebellum and multisensory areas. In particular, music exerts its effects on the brain of patients with epilepsy, having a dichotomous influence: it can either be seizure-promoting in musicogenic epilepsy or antiepileptic. Several studies have shown that seizure-prone neural networks may be stimulated by certain periodicities while other frequencies may prevent seizure activity. There are a lot of data in the literature about the so-called "Mozart effect" (Rauscher et al. 1993). In previous studies we observed that in institutionalized subjects with severe/profound intellectual disability and drug-resistant epilepsy, a systematic music listening protocol reduced the frequency of seizures in about 50% of the cases. In this study we are conducting a survey on the observation of what happens to the brain of patients suffering from drug-resistant epilepsy through electroencephalographic investigations, brain MRI and behavioural analysis before and after six months of listening to Mozart music (Sonata K.448). The first step is to present the data of the first patient under investigation.

Mozart's music and multidrug-resistant epilepsy: a potential EEG index of therapeutic effectiveness.

Multidrug-resistant epilepsy is a pathological condition that affects approximately one-third of patients with epilepsy, especially those with associated intellectual disabilities. Several non-pharmacological interventions have been proposed to improve quality of life of these patients. In particular, Mozart's sonata for two pianos in D major, K448, has been shown to decrease interictal electroencephalography (EEG) discharges and recurrence of clinical seizures in these patients. In a previous study we observed that in institutionalized subjects with severe/profound intellectual disability and drug-resistant epilepsy, a systematic music listening protocol reduced the frequency of seizures in about 50% of cases. This study aims to assess electroencephalography as a quantitative (qEEG) predictive biomarker of effectiveness of listening to music on the frequency of epileptic discharges and on background rhythm frequency (BRF).

Effects of music on seizure frequency in institutionalized subjects with severe/profound intellectual disability and drug-resistant epilepsy.

BACKGROUND: Approximately one-third of patients with epilepsy continue to experience seizures despite adequate therapy with antiepileptic drugs. Drug-resistant epilepsy is even more frequent in subjects with intellectual disability. As a result, several non-pharmacological interventions have been proposed to improve quality of life in patients with intellectual disability and drug-resistant epilepsy. A number of studies have demonstrated that music can be effective at reducing seizures and epileptiform discharges. In particular, Mozart's sonata for two pianos in D major, K448, has been shown to decrease interictal EEG discharges and recurrence of clinical seizures in patients with intellectual disability and drug-resistant epilepsy as well. The aim of this study is to investigate the influence of Mozart's music on seizure frequency in institutionalized epileptic subjects with profound/severe intellectual disability. SUBJECTS AND METHODS: Twelve patients (10 males and 2 females) with a mean age of 21.6 years were randomly assigned to two groups in a cross-over design; they listened to Mozart K448 once a day for six months. RESULTS: A statistically significant difference was observed between the listening period and both baseline and control periods. During the music period, none of the patients worsened in seizure frequency; one patient was seizure-free, five had a greater than 50% reduction in seizure frequency and the remaining showed minimal (N=2) or no difference (N=4). The average seizure reduction compared to the baseline was 20.5%. Our results are discussed in relation to data in the literature considering differences in protocol investigation. CONCLUSIONS: Music may be considered a useful approach as add-on therapy in some subjects with profound intellectual disability and drug-resistant epilepsy and can provide a new option for clinicians to consider, but further large sample, multicenter studies are needed to better understand the characteristics of responders and non-responders to this type of non-pharmacological intervention.

Axonal injury within language network in primary progressive aphasia.

Primary progressive aphasia (PPA) is characterized by an isolated progressive impairment of word use and comprehension reflecting the distribution of pathological processes within the left hemisphere. We used proton magnetic resonance spectroscopy (1H-MRS) to study in vivo the integrity of axonal fibers connecting perisylvian language areas in 11 patients with PPA, 11 subjects with Alzheimer's disease, and 22 controls. Brain metabolites (N-acetylaspartate, myoinositol, choline, creatine) were measured bilaterally within a volume of interest located in the central portion of the superior longitudinal fasciculus, a long associative bundle connecting Broca's area with Wernicke's area, and other language regions of the temporal lobe. In the PPA group, there was an asymmetrical N-acetylaspartate to creatine ratio reduction compared with Alzheimer's disease and controls, with greater changes on the left side. The myoinositol to creatine ratio was increased in the PPA group bilaterally compared with controls. The choline to creatine ratio did not differ among the three groups. These results indicate an asymmetrical focal axonal injury within the language network in PPA. The marked difference in the distribution of N-acetylaspartate to creatine between PPA and Alzheimer's disease suggests that proton magnetic resonance spectroscopy may help to differentiate between these two conditions.
