Does anyone else believe that Casey Anthony has severe mental problems? Why haven't they offered her some mental help?

Studying the case, I believe that she could have some particularly severe mental problems. Her behavior throughout the case, beginning and end, has been either quite bizarre or nonexistent.

In the beginning she didn’t call the police for a month after her child went missing. After that, she led the police around and lied to them constantly.

Does anyone else think that some mental help should have been included with her convictions?
