Read the following passages. Next, determine which is more credible based on the noted sources. Explain your answer.

Example #1

Because of confusion about the symptoms of post-traumatic stress disorder, physicians often misdiagnose it in children. A few common misdiagnoses are depression, hyperactivity, and attention deficit disorder. Because these conditions all share common symptoms, even professionals have trouble differentiating between them. In many cases, anxiety disorders overlap, or an individual may have multiple conditions. The website KidsHealth lists physical complaints and low academic performance as potential symptoms of juvenile PTSD. In addition, traumatized children often develop legitimate learning disabilities and problems with attention and memory. Some teachers at Pickens County Middle School say that children with PTSD are more likely to need remedial classes.

Because of confusion about the symptoms of post-traumatic stress disorder, physicians often misdiagnose it in children. A few common misdiagnoses are depression, hyperactivity, and attention deficit disorder. Because these conditions all share common symptoms, even professionals have trouble differentiating between them. In many cases, anxiety disorders overlap, or an individual may have multiple conditions. An article by Yale medical professor Kevin D. Marshall notes that children with PTSD may vocalize physical complaints, such as stomachaches or headaches, with no medical basis. He also observes that the child's performance in school usually declines significantly. In addition, traumatized children often develop legitimate learning disabilities and problems with attention and memory. Research conducted by medical scientist Mary McLaughlin indicates that children with PTSD are more likely to need remedial classes.
