Pseudoasthma in a case of asthma

Area of Science:

• Pulmonology and Otolaryngology

Background:

• The respiratory system encompasses upper and lower airways, susceptible to diverse pathologies like asthma and laryngeal dysfunction.
• Non-organic laryngeal dysfunction, often functional, presents with abnormal vocal cord movements and is increasingly recognized.
• Symptoms of functional laryngeal dysfunction can be misdiagnosed as asthma, leading to inappropriate management.

Observation:

• This case study details a patient with co-existing asthma and functional laryngeal dysfunction.
• The patient exhibited paradoxical vocal cord motion during inspiration, confirmed via direct laryngoscopy.
• The laryngeal dysfunction was considered an isolated entity, potentially exacerbated by emotional events.

Findings:

• The patient displayed paradoxical vocal cord motion on inspiration, a hallmark of functional laryngeal dysfunction.
• This condition, often linked to psychological factors like anxiety and depression, can present acutely.
• Shortness of breath associated with this dysfunction may or may not be accompanied by stridor.

Implications:

• Accurate diagnosis is crucial to differentiate functional laryngeal dysfunction from asthma.
• Speech and vocal cord exercises are recommended as the primary treatment during acute episodes.
• Recognizing this distinct clinical entity ensures appropriate therapeutic interventions and improves patient outcomes.
