• An international team of researchers from New Zealand, Finland, Canada, and the USA conducted a study to assess the neuroanatomical cause of acquired stuttering and find a common cause for developmental stuttering. 

• Following were their findings -

1. Published case reports (n = 20) and a clinical single study cohort with acquired neurogenic stuttering following stroke (n = 3, 20 cases, and 17 controls) were analyzed to find a neurological lesion network responsible for this.

2. This was then analyzed with a cohort of adults with persistent developmental stuttering (n=20) to find if this lesion-based network was relevant to developmental causes.

3. The results showed the lesions were functionally connected to a common network centered around the left putamen, amygdalostriatal transitional area, and claustrum.

4. The researchers noted that the last two areas are new regions discovered to have an effect and can be further analyzed to confirm their effect.

• This can lead to a new direction in diagnosing and treating these disorders.
