Rare Brain Disorder Robbed Robert F. Kennedy Jr. :Understanding Spasmodic Dysphonia

  1. Adductor Spasmodic Dysphonia: The most common form, characterized by sudden, involuntary muscle movements that cause the vocal cords to close tightly. This results in a strained, strangled voice.
  2. Abductor Spasmodic Dysphonia: Less common; this type causes the vocal cords to open involuntarily, leading to a breathy, whispery voice.
  3. Mixed Spasmodic Dysphonia: A combination of both adductor and abductor symptoms, making speech even more unpredictable.
  • A strained, hoarse, or shaky voice
  • Breaks or interruptions in speech
  • Difficulty projecting the voice
  • Voice fatigue after prolonged speaking
  1. Botulinum Toxin (Botox) Injections: Botox injections are the most common treatment and are administered directly into the affected vocal cord muscles. These injections temporarily paralyze the muscles, reducing spasms and improving voice quality. However, the effects wear off after a few months, requiring repeat treatments.
  2. Voice Therapy: Working with a speech-language pathologist can help individuals develop techniques to minimize the impact of spasms on their speech. While voice therapy cannot eliminate the disorder, it can provide valuable tools for coping with symptoms.
  3. Surgical Interventions: In severe cases, surgical procedures such as selective laryngeal adductor denervation-reinnervation (SLAD-R) may be considered. This involves cutting and reconnecting nerves to reduce spasms.
  4. Stress Management: Since stress can worsen symptoms, meditation, yoga, and cognitive-behavioral therapy may be beneficial.
