Sleep Apnea

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...

Summary

Obstructive sleep apnea (OSA) patients exhibit enhanced brain connectivity, particularly in the right hemisphere, when listening to Neelambari music. This music may positively influence neural synchronization and brain dynamics in individuals with OSA.

Background:

Obstructive sleep apnea (OSA) is a serious condition causing breathing difficulties during sleep and increasing risks of heart attack and stroke.
Brain connectivity analysis is proposed to investigate the impact of OSA under different auditory conditions.

Purpose of the Study:

To investigate the impact of obstructive sleep apnea (OSA) on brain connectivity patterns.
To analyze brain connectivity during exposure to specific music types (Neelambari, Kapi) and silence.

Main Methods:

Electroencephalogram (EEG) recordings were collected from 12 subjects under three conditions: Neelambari music, Kapi music, and no music.
EEG signals were pre-processed using bandpass and notch filters, and sub-bands (delta, theta, alpha, beta) were extracted using wavelet packet decomposition (WPD).
Brain connectivity was assessed using Pearson Correlation on WPD detail coefficients and graph theory's node strength metric.

Main Results:

Listening to Neelambari music (Music 1) significantly increased brain connectivity in the right hemisphere's frontal and temporal regions (F8, FC6, T8).
High correlation values were observed across all frequency bands (delta, theta, alpha, beta) during Neelambari music exposure, indicating strong neural synchronization.
Neelambari music demonstrated stronger neural synchronization compared to Kapi music, with consistently higher correlation values.

Conclusions:

Obstructive sleep apnea (OSA) patients show positive brain connectivity when listening to Neelambari music.
Neelambari music may positively modulate brain dynamics and neural synchronization in OSA patients.
