Lesson Transcript
Instructor: Artem Cheprasov

Artem has a doctor of veterinary medicine degree.

We all have good days and bad days, and we all sometimes think we hear something when there is really nothing there. But for some people, their mood, personality or psychotic disorder is more than a passing matter.

Mood, Personality & Psychotic Disorder

Hey! Are you feeling okay today? I hope so. We've all had our days, though, where our personality was just not the same as most people expect it to be. But that's just part of life; we can't always be happy-go-lucky! For some individuals, unfortunately, they actually have a mood, personality or even psychotic disorder that makes life miserable. In this lesson, we'll take a look at some of these mood, personality and psychotic disorders.

Mood Disorders

One mood disorder is bipolar disorder, a mood disorder that has radical mood swings and emotional changes at its core, from manic highs to depressive listless lows. Manic behavior includes the inability to sleep, increased irritability, overt elation that is not in line with circumstances, bad judgment and bad social behavior.

Depression is a mood disorder that includes a loss of interest in once-pleasurable activities, lethargy, despair, sadness, a feeling of being worthless and thoughts of suicide. As I sort of hinted at in the intro, the mood swings associated with bipolar disorder are far more severe than a person who is just sad that their friend didn't show up to a party one day but is happy to see them the next.

Another mood disorder, and one form of depression, is seasonal affective disorder (SAD), which is a form of depression commonly associated with a decrease in daylight hours in winter months. Most people are kind of bummed when it's cold outside and they have to come in and leave work when it's dark out. But people with SAD are far more affected by this.

Another type of depression is dysthymia, a type of chronic, long-term mood disorder with milder symptoms than severe depression. A person has to have these feelings of depression on an almost daily basis for at least two years in order to be diagnosed with this mood disorder. The word 'dysthymia' comes from 'dys-', which means 'bad', 'thym-', which means 'mind' in this case, and '-ia', which refers to a 'state'. So, it's literally a bad state of mind, dys-thym-ia.

Personality Disorders

For outsiders looking in, it may be really easy to label someone in a depressed or manic-depressive state as someone who has issues with their personality. Of course, that's wrong on two fronts, as not only are the individuals suffering from a medical condition, but a personality disorder is not the same thing as a mood disorder, even if mood changes may be part of some personality disorders.

A personality disorder is any one of a group of disorders where a person has inflexible, ingrained and maladaptive patterns of subjective internal experience and behavior that disrupt their ability to properly interrelate.

There are many examples of personality disorders, including:

  • Antisocial personality disorder, where a person's actions and ways of relating and thinking show a disregard for the rights of others.
  • Borderline personality disorder, where there is a pattern of impulsive acts, instability and chaos in relationships and mood.
  • Narcissistic personality disorder, where a person showcases a pattern of an exaggerated sense of self-importance and an abnormal need for attention and admiration, with a lack of empathy for others.

Psychotic Disorder

You might think that such selfish individuals have lost touch with reality, and maybe so. But actually, a disorder characterized by a loss of touch with reality, such as delusions and hallucinations, is appropriately called a psychotic disorder.

A delusion is a false belief without proof of evidence for the belief or the belief in a thought despite evidence to the contrary. Such a belief is also one that isn't normally accepted by the person's culture or society.
