Epilepsy and music: practical notes.

Area of Science:

• Neuroscience
• Neurology
• Music Cognition

Background:

• Music processing involves complex brain networks beyond auditory cortices.
• This network can be sensitized by music, potentially triggering seizures (musicogenic epilepsy) or musical phenomena during seizures.
• The direct effect of sound waves on brain waves suggests music's therapeutic potential for epilepsy.

Purpose of the Study:

• To review the evidence for music's effect on epilepsy.
• To discuss the implications of music processing for epilepsy treatment and surgery.
• To highlight the need for understanding music's dichotomous effects on seizures.

Main Methods:

• Literature review of studies on music, epilepsy, and brain wave interactions.
• Analysis of evidence regarding the antiepileptic effects of specific musical pieces, such as Mozart Sonata K.448.
• Examination of clinical observations and surgical cohort studies concerning music perception and epilepsy medication.

Main Results:

• Limited and low-quality evidence suggests a potential antiepileptic effect of Mozart Sonata K.448.
• A clear pathophysiological explanation for music's dual effect on seizures is lacking.
• Antiepileptic drugs like carbamazepine and oxcarbazepine can reversibly alter pitch perception.
• Epilepsy surgery, particularly right temporal lobe surgery, may impact musical memory and perception.

Conclusions:

• Clinicians should consider patients' musicality when prescribing antiepileptic drugs or planning epilepsy surgery.
• Presurgical counseling should include the risk of altered musical perception after surgery.
• Further research is needed to elucidate the mechanisms behind music's influence on epilepsy.
