Overview
- Roughly one percent of people in Germany—about 830,000 to 840,000—stutter, with men affected around four times as often as women.
- Stuttering typically begins between ages two and six; about five percent of children are affected, and 70 to 80 percent of those cases resolve naturally.
- A Nature Genetics study reports 57 genomic loci linked to stuttering, yet researchers stress the causes remain unclear and a German neurologist criticizes the survey-based data.
- Logopedic care focuses on stuttering modification and fluency shaping along with work on speaking-related anxiety, and the Kasseler Stottertherapie reports more than 4,500 insurance-funded treatments with parent training for very young children.
- Advocacy groups say public awareness has improved but stigma and barriers in media, politics, and employment persist, urging support for self-help, nationwide therapy access, and patient listening without interrupting.
