Investigators at the National Institute of Neurological Disorders and Stroke (NINDS) are seeking family members with stuttering or other speech articulation disorders—such as phonological disorders—for a genetic study and to develop criteria for defining and differentiating patients with stuttering from those with other speech disorders. Stuttering is characterized by sound and syllable repetitions and consonant/vowel prolongations. Speech articulation or phonological disorders are related, but different, speech disorders characterized by omissions, substitutions, or distortions of sounds.

To be eligible, participants must have developmental stuttering with onset prior to puberty, with or without subsequent recovery, or developmental phonological disorders such as speech sound omissions or errors during conversational speech with poor error awareness, with or without subsequent recovery. Patients who developed stuttering following brain injury are not eligible.

The study will be conducted at the National Institutes of Health (NIH) Clinical Center in Bethesda, MD. All study-related expenses will be paid by the NIH. The study will be carried out under testing and safety standards of the U.S. Department of Health and Human Services.

For more information, physicians should send a referral letter and a copy of the patient's recent medical records to Kimberly Bidus, NINDS, NIH, Building 10, Room 5D38, 10 Center Drive MSC 1164, Bethesda, MD 20892-1164; telephone: (301) 496-9367; fax: (301) 480-0803; email:
