Panic Anxiety Disorders:

The introductory anxiety information section contains a brief outline of anxiety disorders, symptoms and treatments, a dictionary of related terminology, and an online screening test for anxiety, among other resources. The advanced section offers a collection of articles in the field of anxiety disorder research.

This website is useful to both medical professionals and patients in that it covers both basic and detailed information about panic disorder and anxiety attacks.

Medical links to related panic and anxiety disorders such as depression and bipolar disorder, sexual abuse and trauma, mitral valve prolapse and thyroid disease, medications and nutrition are also both relevant and useful.

Only catch is that this site is part of the About.com network of niche vertical sites for users and profit driven marketers. Although sites such as these can be very informative, I suggest you have your VISA information in the next room; otherwise you may induce a panic attack by ending up on their Shopping Centre, Wellness Center and of course Bingo link.
