Several other studies have found a relationship between asthma and other anxiety disorders, Dr. Goodwin noted, yet this study is the first to investigate the link between asthma and PTSD. This new research also confirmed previous findings that linked asthma with a higher risk of depression.

"The reason (s) for the association between asthma and mental disorders is not known. Asthma could increase the risk of anxiety disorders, or anxiety disorders might cause asthma, or there could be common risk factors for both asthma and anxiety disorders. Our study found the association between asthma and PTSD does not appear to be primarily due to a common genetic predisposition,” she said.

The researchers found the association between asthma and PTSD existed even after they took into account factors such as cigarette smoking, obesity and socioeconomic status, all of which are associated with both anxiety disorders and asthma. "It is conceivable that traumatic stress, which has been associated with compromised immune functioning, leads to increased vulnerability to immune-system-related diseases, including asthma,” Dr. Goodwin said.

“Alternatively, it may be that having asthma places adults at increased risk for PTSD as it increases thelikelihood that they will be exposed to a traumatic situation because they have a life-threatening chronic medical condition,” she added.

The findings suggest that a person with asthma who experiences a traumatic event may benefit from seeking professional help, because they could be more vulnerable to developing post-traumatic stress disorder, she said.

The research is published in the first issue for November 2007 of the American Journal of Respiratory and Critical Care Medicine, published by the American Thoracic Society.

Many PTSD suffers experience panic disorder or other respiratory altering anxiety conditions. I have encountered several cases people suffering from PTSD being diagnosed with asthma by their general practitioner based on their report of tight chest etc when in fact asthma is not present. Even where a bronchodilator is effective it is not always clear whether it was bronchial dilation fixing the problem or simply that the inhaler reassured them and hence reduced their anxiety. Another explanation, along similar lines, is that those with respiratory anxiety symptoms (common in PTSD) are more likely to focus on breathing and hence have genuine asthma diagnosed, while many cases in the general population remain undiagnosed. I believe there could be a number of explanations for the association that are not necccessarily. I would be interested to know if the study ruled these out?

P.S. I should state that I am not ruling out a causal role and would not be surprised if it were oresent
