10 of wrestling's craziest personalities

#8 Rowdy Roddy Piper, Bipolar Disorder

Roddy was known for his 'manic' phases.

Smiling and laughing one moment, smashing out someone's brains with a coconut the next, Roddy Piper is a near-perfect example of Bipolar Disorder.

People with BPD are likely to suffer from sudden shifts in mood, often with no regard to outside stimulus. They can find it hard to hold down jobs or interact with normal society due to their unpredictability.

Piper certainly had some tension with other wrestlers and was known for his sudden shifts in temperament. Check out this classic interview where he smashes a bottle over his own head to show the Sheepherders just how crazy he is.

Treatment:

There are different causes of BPD, resulting in differing treatments. If the BPD is caused by a chemical imbalance in the brain, then drugs will be effective. If, however, the condition was brought on by trauma, then psychotherapy might be the best option.

When doctors decide when or how to treat Bipolar disorder, they often look at how it affects the life of the patient. Since Piper's manic episodes seem to work out to his advantage most of the time, he may not even require treatment.
