Hi Bill. That's a great question about subtypes. The numbers seem to support that 70% of people who stutter have relatives who stutter and 30% of people who stutter do not have an identified relative who stuttered. Per Alm has done some great research and suggests that many more of the people who do not have a known genetic link experienced early head trauma, or difficulties at birth (lack of oxygen, instruments used, etc.) and that those without the link are also much more likely to show ADHD-like symptoms than are those with genetic histories... so there seem to be at least two paths toward stuttering. Whether one path is more likely to recover in any way or is different is still unknown. Take care, Joe.
