The defense for Jerry Sandusky is trying its hardest to convince a jury that he is innocent. According to Laura Nichols, the judge in the case has allowed the defense to summon an expert opinion that Sandsuky has "histrionic personality disorder."

Judge Cleland permits #Sandusky defense to present expert opinion re: #Sandusky has a "histrionic personality disorder"

Histrionic personality disorder is a rare personality disorder that begins in adulthood. SB Nation's Ryan O'Hanlon previously mentioned the symptoms of the disorder.

The symptoms are often over-the-top behavior, extra-theatrical emotion, and other kinds of attention-seeking behavior.

Despite this, it isn't an easily diagnosed disorder, since many sexual predators exhibit some form or another of these symptoms. So it appears fairly likely that a defense like this could fall flat for Sandusky.
