Aerotoxic syndrome

Aerotoxic syndrome is a term used to describe a range of health conditions purportedly caused by exposure to contaminated air in aircraft. It is a controversial subject in medicine as there is no consensus on whether the condition exists. The term was coined by Dr. Harry Hoffman, Professor Chris Winder, and Jean-Christophe Balouet, Ph.D., in 1999.

Causes

The primary cause of aerotoxic syndrome is believed to be exposure to tricresyl phosphate (TCP), an anti-wear additive used in jet engine oil. In certain circumstances, such as engine malfunction or overheat, TCP can contaminate the cabin air supply through the aircraft's bleed air system.

Symptoms

Symptoms of aerotoxic syndrome can vary widely but often include neurological issues such as headache, dizziness, and numbness, as well as respiratory problems like cough and shortness of breath. Other symptoms can include nausea, vomiting, fatigue, and rashes.

Diagnosis

Diagnosis of aerotoxic syndrome is challenging due to the wide range of symptoms and the lack of specific diagnostic tests. It is often a diagnosis of exclusion, made after other potential causes of the symptoms have been ruled out.

Treatment

Treatment for aerotoxic syndrome is primarily symptomatic, focusing on managing individual symptoms. This can include medication for headaches, dizziness, and respiratory problems, as well as physiotherapy for persistent physical symptoms.

Controversy

The existence of aerotoxic syndrome is not universally accepted within the medical community. Critics argue that there is insufficient evidence to establish a clear link between exposure to cabin air and the symptoms described. However, advocates for recognition of the condition argue that the lack of research and understanding of the potential health effects of cabin air contamination is a significant issue that needs to be addressed.
