Tackling Laryngeal Sensory Neuropathy (LSN)

For Chronic Cough Sufferers That Have Tried It All, Relief Is in Sight; Cough Expert, Brian Rotskoff, MD, Talks About Treating All the Causes of Cough

CHICAGO, IL--(Marketwired - Feb 27, 2014) - Anybody that has a chronic cough knows that a cough is more than just a cough. Chronic cough can disrupt your life, and for sufferers that have sought treatment to no avail, many are asking, "What more can I do?" Until recently, a limited understanding of cough diagnoses, such as Laryngeal Sensory Neuropathy (LSN) has challenged patients to find effective treatment and real results.

"Although LSN is very common, few doctors understand how to diagnose or treat the disorder," explains Chicago allergist and cough expert, Brian Rotskoff, MD. "Unfortunately for chronic cough sufferers, if the cough is not treated wholly, then they will never find relief."

LSN: A Case Study
As an allergist and cough expert, Dr. Rotskoff has treated many coughs and he knows that no two coughs are the same. "Traditionally, we have understood cough to have three main causes: asthma, acid reflux, and post-nasal drip," he explains. "While it is still true that many chronic coughs are caused by these conditions, it's not always that simple. As soon as I hear that a new patient has tried it all, including seeing other physicians, I know that this is a patient that needs an out-of-the-box perspective."

Take for instance, the case of Lisa, a 45-year-old woman with a one-year history of severe chronic cough. With a history of heartburn symptoms (acid reflux) as well as wheezing and shortness of breath (suggestive of asthma), it seems rather straightforward to diagnosis these conditions as the causes of her chronic cough. However, Lisa came to Dr. Rotskoff -- still coughing -- after being treated by both an allergist and a lung specialist.

"I suspected that one of the primary causes of Lisa's cough was LSN, which occurs when there is damage to the larynx and throat area," explains Dr. Rotskoff. "The larynx becomes hypersensitive to a number of factors that normally would not cause a problem for the patient. For instance, acid reflux and post-nasal drainage from allergies may cause severe irritation in the hypersensitive larynx."

Knowing that this disorder leads to nerve damage of the cough receptors in the larynx and throat, Dr. Rotskoff prescribed medications to help heal Lisa's injured tissue and allow her nerves to repair. Over a six-week period Lisa's cough began to gradually improve. At her follow up visit, her cough was approximately 75% better. At this point in her treatment, Dr. Rotskoff was ready to move on to treating Lisa's acid reflux and asthma. In less than three months of total treatment, Lisa's cough was completely gone. 

"The important point to understand about Lisa's cough is that although there were many contributing factors, Laryngeal Sensory Neuropathy was the primary cause," says Dr. Rotskoff. "Until we treated the LSN, her cough would not have responded to any other treatments. Unfortunately, partial remedies were the reason Lisa suffered for so long."

If you are experiencing long-term, persistent coughing and have exhausted traditional treatments, call Dr. Rotskoff at Clarity Allergy Center in Chicago. The sooner you start your chronic cough treatment, the sooner you will find relief.
