Laryngeal Dystonia

Laryngeal Dystonia, also known as spasmodic dysphonia, is a rare neurological disorder that affects the muscles of the larynx (voice box). This condition can cause various speech-related issues and is characterized by involuntary muscle contractions in the throat, leading to voice disruptions. In this article, we’ll provide simple explanations of the types, causes, symptoms, diagnostic tests, treatments, drugs, and surgical options for laryngeal dystonia.

Types of Laryngeal Dystonia:

  1. Adductor Spasmodic Dysphonia:
    • This is the most common type.
    • It causes the vocal cords to close too tightly during speech.
    • People may experience a strained or strangled voice quality.
  2. Abductor Spasmodic Dysphonia:
    • In this type, the vocal cords open too much during speech.
    • It results in breathy and weak-sounding speech.

Causes of Laryngeal Dystonia:

  1. Genetics:
    • Some cases may have a genetic predisposition.
  2. Brain Abnormalities:
    • Brain injuries or abnormalities can trigger laryngeal dystonia.
  3. Environmental Factors:
    • Exposure to toxins or pollutants may contribute.
  4. Stress:
    • High-stress levels can exacerbate symptoms.
  5. Trauma:
    • Physical injuries to the neck or larynx can lead to this condition.
  6. Infections:
    • Certain infections can affect the nervous system.
  7. Medications:
    • Some medications may cause or worsen symptoms.
