why is rfk jr voice like it is

Robert F. Kennedy Jr.'s voice sounds the way it does because he has a rare neurological condition called spasmodic dysphonia. This disorder causes involuntary spasms in the muscles that control his vocal cords, making his voice strained, shaky, and sometimes breathy or strangled. The condition affects about 50,000 people in North America and typically arises in midlife. It is not caused by vocal overuse but by neurological abnormalities in the brain's nerve signaling that control muscle movement of the vocal cords. Kennedy has spoken openly about how the condition makes his voice sound terrible despite not feeling tired vocally and that the more he uses his voice, the stronger it tends to get. Spasmodic dysphonia is chronic and currently incurable, but treatments like Botox injections can help manage symptoms.
