Janus-faced Syndrome

Bipolar I disorder is often called the Janus-faced Syndrome because a person will go through a series of depression and mania, which makes a person seem like they are two faced.  When a person is in  a manic state they will have an elevated mood that is not justifiable.  Most times they will be over the moon for no reason at all.  They will have increased energy, grandiosity or rage states.  They will have a reduced need for sleep. They will be more active,  have pressured or rapid speech, rapid and constant thoughts.  They will engage in risky and irresponsible behaviors. Sometimes people even become psychotic during a manic episode.  The depression episode is when they are the opposite of when they are having the manic episode.  This means they are sad and have no energy.  Often they will just want to be alone and have nothing to do with anyone or anything.  Each of these episodes will last at the minimum of a week at a time

There is another bipolar disorder.  This one is less severe and with a shorter time of duration.  Bipolar II disorder in also less intense than bipolar I disorder.
