A sudden reflexive closure of the larynx occurring when the individual is trying to breathe. Occurs more frequently in persons who have [intlink id=”641″ type=”post”]vocal fold paralysis[/intlink] or in those experiencing [intlink id=”488″ type=”post”]sensory neuropathic cough[/intlink]; also seen as an aftermath of an upper respiratory infection. Typical episodes begin abruptly and last approximately one minute. The individual often makes loud inspiratory noises whose loudness abates gradually over the first minute or two. The voice may be choked off during the same time, making it difficult to speak. Laryngospasm is terrifying not only to the person experiencing it but also to family, friends, or strangers observing the episode. May awaken its victim from sound sleep. Rarely, an individual will experience a series of laryngospasms, making it appear that they are having one much longer spasm.
