Can anyone help?

You are a volunteer at a counseling center, and your mentor has asked you to assist in leading a session of a psycho-educational group on a disorder of your choice. 

Address the following:

• Identify a disorder that is usually diagnosed first in childhood/adolescence, and provide a thorough explanation of the characteristics of the disorder.
• Research the disorder using your textbook, Web resources, and other professional literature to explain (in detail) complexities in identifying the disorder.
• You will need to write a realistic case (you should create the details) to use as an example in explaining all aspects of the disorder.

You should cite sources using APA format, and include a reference section at the end of your submission
