Summary
Obstructive sleep apnoea (OSA) is common and affects the brain and heart. This review explores its causes, including genetics, and how risk factors like obesity contribute to airway collapse during sleep.
Area of Science:
- Sleep Medicine
- Genetics
- Respiratory Medicine
Background:
- Obstructive sleep apnoea (OSA) is a prevalent disorder characterized by repetitive airway collapse during sleep.
- OSA has significant neurocognitive and cardiovascular health implications.
- The underlying pathophysiology and inter-individual variations in OSA are not fully understood.
Purpose of the Study:
- To review current knowledge on the pathogenesis of adult OSA.
- To highlight the potential role of genetic factors in OSA development.
- To explore mechanisms linking major risk factors to OSA.
Main Methods:
- Literature review of state-of-the-art knowledge on OSA pathogenesis.
- Analysis of risk factors including obesity, male gender, and ageing.
- Exploration of genetic influences on pathophysiological traits.
Main Results:
- Obesity, male gender, and ageing are key risk factors for OSA.
- Mechanisms linking these risk factors to OSA pathophysiology require further investigation.
- Genetics may play a significant role in individual susceptibility and trait variation in OSA.
Conclusions:
- Understanding OSA pathogenesis is crucial for effective management.
- Further research into the genetic underpinnings of OSA is warranted.
- Investigating the interplay between environmental factors and genetics will advance OSA treatment strategies.

01:21Sleep 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.

01:20Chronic Obstructive Pulmonary Disease-II: Pathophysiology
Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:
Chronic Inflammation
Chronic Inflammation
01:17Other Pulmonary Disorders
Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.
01:30Pulmonary Hypertension: Classification and Pathogenesis
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

01:28Human Genetics
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

01:23Chronic Obstructive Pulmonary Disease I: Introduction
Chronic obstructive pulmonary disease is a common, preventable, and treatable respiratory disorder characterized by persistent symptoms and progressive airflow limitation. This limitation results from a combination of small-airway disease (obstructive bronchiolitis) and parenchymal destruction (emphysema), both driven by chronic inflammation from exposure to harmful particles or gases.The disease includes two main pathological entities: emphysema, marked by destruction of alveolar walls and...
