Thank you for visiting the National Institute of Mental Health (NIMH) Web site and reviewing our policies. NIMH does not endorse or recommend any commercial products or services. Inclusion of an author's views or opinions on our Web sites does not mean they state or reflect those of NIMH or the U.S. Government, and private parties may not use them for advertising or product endorsement purposes.

Medical Information

NIMH does not intend to provide specific medical advice on our Web sites, but rather to help visitors better understand mental health and disorders. NIMH will not provide specific medical advice and urges you to consult with a qualified mental health or health care provider for diagnosis and for answers to your personal questions.

Pop-Up Advertisements

When visiting our sites, your Web browser may produce "pop-up" advertisements (advertisements that spontaneously appear on your computer screen). The most likely source of such an advertisement is another Web site you visited or third-party software on your computer. NIMH does not endorse or recommend products or services featured in advertisements that "pop up" during your visit to our sites.

The public may reproduce without permission information from the National Institute of Mental Health Web site, except for documents that state another copyright policy applies to them. Restrictions on the reproduction of a document may arise if a private party has sponsored it. The NIMH, however, is the sole sponsor of most of the information on this site. Some images on the NIMH site may be restricted and protected by U.S. and foreign copyright laws and may not be copied or used for other purposes.

Information and Publications

NIMH information and publications are in the public domain and may be reproduced or copied without permission. NIMH encourages you to reproduce them and use them in your efforts to improve public health. Citation of the National Institute of Mental Health as a source is appreciated.

Using government materials inappropriately, however, can raise legal or ethical concerns, so we ask you to follow these guidelines:

  • NIMH does not endorse or recommend any commercial products, processes, or services. You may not use NIMH publications for advertising or endorsement purposes.
  • NIMH does not provide specific medical advice, treatment recommendations, or referrals. You may not use NIMH publications in a manner that has the appearance of such information.
  • NIMH requests non-Federal organizations to not alter publications in a way that will jeopardize the integrity and NIMH "brand."
  • Addition of non-Federal Government logos and Web site links should not imply an NIMH endorsement of any specific commercial products or services and/or medical treatments or services.
  • Images used in publications are of models and are used for illustrative purposes only. Use of some images is restricted.

If you have questions regarding these guidelines and use of NIMH publications, please contact the NIMH Information Center at 1-866-615-6464 or at
