Defining Psychological Disorders

abnormal psychology
Applying psychological science to our understanding and treatment of psychological disorder. About 1 in every 4 Americans (or over 78 million people) are affected by a psychological disorder during any one year, [4] and at least a half billion people are affected worldwide. The impact of mental illness is particularly strong on people who are poorer, of lower socioeconomic class, and from disadvantaged ethnic groups

prevalence
the frequency of occurrence of a given condition in a population at a given time

psychological disorder
An ongoing dysfunctional pattern of thought, emotion, and behavior that causes significant distress, considered deviant in that person’s culture or society. Have much in common with other medical disorders. Out of the patient’s control, in some cases are treated by drugs, their treatment is often covered by medical insurance. Like medical problems, have both biological (nature) as well as environmental (nurture) influences. These causal influences are reflected in the bio-psycho-social model of illness. Social-Cultural Influences, Biological Influences, Psychological influences

bio-psycho-social model of illness
a way of understanding disorder that assumes that disorders are caused by biological, psychological, and social factors

biological component
the influences on disorder that come from the functioning of the individual’s body

psychological component
If the bio-psycho-social model refers to the influences that come from the individual, such as patterns of negative thinking and stress responses.

social component
the bio-psycho-social model refers to the influences on disorder due to social and cultural factors such as socioeconomic status, homelessness, abuse, and discrimination.

Psychological Influences

Social-cultural Influences
Pattern of negative relationships with other people
Homelessness
Cultural Expectations
Stigma and prejudice
Gender roles
Socio-economic status
Definitions of normality and disorder

Biological Influences
Brain Structure
Genetics
Imbalance of the neurotransmitter, Serotonin
Abnormality within the brain

Comorbidity
occurs when people who suffer from one disorder also suffer at the same time from other disorders. Because many psychological disorders are comorbid, most severe mental disorders are concentrated in a small group of people (about 6% of the population) who have more than three of them.

stigma of phycological disorder
a disgrace or defect that indicates that person belongs to a culturally devalued social group. . In some cases the stigma of mental illness is accompanied by the use of disrespectful and dehumanizing labels, including names such as “crazy,” “nuts,” “mental,” “schizo,” and “retard.”

employment discrimination

hopelessness

Diagnostic and Statistical Manual of Mental Disorders (DSM)

published in 1952
revised five times

In the DSM-5, The role of Type 1 Diabetes is
documented right along with a clinical disorder and any presence of a personality disorder

Diagnosis of Depressive Disorder is documented
along with any existing personality and/or medical illnesses

The purpose of the DSM-5 is to provide

Obsessive-compulsive disorder (OCD)
psychological disorder that is diagnosed when an individual continuously experiences obsessions (distressing, intrusive, or frightening thoughts), and engages in compulsions (repetitive behaviors or mental acts) in an attempt to calm these obsessions.

A short (up to 20 minute) period of time characterized by intense anxiety is known as a(n):

Mood Disorders

mood
the positive or negative feelings that are in the background of our everyday experiences

Mood (or affective) disorders
Person’s mood negatively influences his or her physical, perceptual, social, and cognitive processes. People who suffer from mood disorders tend to experience more intense (and particularly more intense negative) moods. About 10% of the U.S. population suffers from a mood disorder in a given year.

dysthymia
a condition characterized by mild, but chronic, depressive symptoms that last for at least 2 years.

Major depressive disorder (clinical depression)
An all-encompassing low mood accompanied by low self-esteem and by loss of interest or pleasure in enjoyable activities. In some cases people lose contact with reality and may receive a diagnosis with psychotic features. In these cases depression includes delusions and hallucinations.

Experiences with depression are followed by a more normal period and then a period of mania or euphoria in which the person feels particularly awake, alive, excited, and involved in everyday activities but is also impulsive, agitated, and distracted

neurogenesis
the process of generating new neurons; Antidepressant drugs may alleviate depression in part by increasing neurogenesis

selective serotonin reuptake inhibitors (SSRIs)
The researchers focused on this gene because serotonin is known to be important in depression; have been shown to be effective in treating depression

Results From Caspi et al., 2003
This important study provides an excellent example of how genes and environment work together: An individual’s response to environmental stress was influenced by his or her genetic makeup.

serotonin
