In another interview for a new broadcast 2023, he said, "It makes my voice tremble. At the time, I didn't know what was wrong with it. But when I would go on TV, people would write me letters and say, 'You have spasmodic dysphonia."

In an interview to Los Angeles Times, he said, "My voice doesn't really get tired. It sounds terrible. But the injury is neurological, so actually the more I use the voice, the stronger it tends to get." In the same interview he said that he "can't stand" his own voice. He said, "I feel sorry for the people who have to listen to me."

Spasmodic Dysphonia or SD is a rare disorder that causes involuntary movements of the voice box. It happens to about 1 in 100,000 people worldwide. As per Saul Frankford, an assistant professor in the School of Behavioral and Brain Sciences at the University of Texas at Dallas, who has researched the condition tells Time that there are two main types of SD. What RFK Jr. has is adductor spasmodic dysphonia, where "the vocal folds press too tightly together during a speech." 

Frankford says, "This causes this raspy or creaky kind of voice, often with voice breaks as well." Whereas abductor spasmodic dysphonia is the kind where vocal cords suddenly opens and leads to a "breathier kind of voice." 

As per the Cleveland Clinic, spasmodic dysphonia is a rare, lifelong neurological disorder that affects speech by causing involuntary spasms in the muscles controlling the vocal folds. These spasms disrupt normal voice production, making the voice sound shaky, breathy, strained, or hoarse, sometimes as if the person has lost their voice.

The spasms may tighten the vocal cords, creating a strained, tense sound, or pull them apart, resulting in a breathy tone. A person’s voice can unpredictably shift—from a soft whisper to a harsh, broken sound—causing words to cut off mid-sentence.

Though there is no cure, treatments like Botox injections, voice therapy, or thyroplasty can help manage symptoms and make speaking easier.

Spasmodic dysphonia originates in the basal ganglia, a part of the brain that helps control involuntary muscle movements. When the brain sends faulty signals, the muscles in the larynx and vocal cords spasm. Because it’s a type of dystonia, conditions linked to abnormal muscle control—it’s also known as laryngeal dystonia.

The exact cause is still unclear. In some cases, it may be tied to inherited gene variants, about one in four people with the condition have a family history of dystonia. It can also develop after an illness or injury. Notably, women are three times more likely to be affected than men.

<h2>Treatment for Spasmodic Dysphonia</h2>

Botox injections (most common): Botox works by blocking the nerve signals that trigger spasms, allowing smoother speech. The effects usually last around four months, so regular injections are needed to maintain results.

<strong>Voice therapy: </strong>Speech-language pathologists (SLPs) can teach exercises to improve voice control. Voice therapy is most effective when combined with Botox treatment.

<strong>Communication aids: </strong>Devices and apps can amplify the voice or convert typed text into speech, providing additional support in daily communication.

<h3>Surgical options for adductor spasmodic dysphonia:</h3>

<strong>Type II thyroplasty: </strong>This procedure repositions the vocal cords by adjusting the supportive tissue in the voice box, helping them stay farther apart.

Selective laryngeal adductor denervation-reinnervation (SLAD-R): In this surgery, certain nerves controlling the vocal cords are disconnected and then reconnected to different nerves, altering how signals travel from the brain to the vocal cords.

As for RFK Jr., he underwent experimental titanium bridge surgery in Kyoto, the surgery is not yet approved in the US. The surgery comprises of surgeons implanted a titanium bridge between his vocal cords to prevent them from pressing together.
