Bipolar Disorder Flashcards
What are disorders of affect
-a set of psychiatric disorders, also called mood disorders.
-The main types of affective disorders are depression and bipolar disorder.
What is a mood disorder?
-Emotions are amplified beyond the normal ups and downs, in either extremely negative or positive directions which can persist for long periods of time.
-Individuals might experience strong feelings of
despair and emptiness; in other instances they may also feel anger or euphoria.
-Disorders involving abnormal affect significantly impair the individual’s ability to function normally.
What is unipolar depression?
-Unipolar depression is another name for major depressive disorder.
-The term “unipolar” means that this form of depression does not cycle through other mental states, such as mania.
What is bipolar disorder?
-Bipolar disorder, (also known as manic depression) is a serious mental illness that causes unusual and severe mood changes.
-The person may experience ‘highs’ (clinically known as mania) and ‘lows’ (known as depression), which may persist for a few days or many weeks.
-The person may experience distinct episodes of mania and depression, and these episodes may switch rapidly, even multiple times in one week.

• Loss of interest in enjoyable activities
Changes in behaviour
• Struggling to concentrate or remember easily
• Withdrawing from activities or friends
• Fatigue or lethargy
• Finding it difficult to make decisions

• Considering or attempting suicide
Psychometric tests
-They are used to measure an individual’s mental capabilities and behaviour.
-They are designed to show your overall suitability for a particular role based on your performance.
-They show your personality characteristics and aptitude/cognitive ability.
A good way to measure depression
Beck Depression Inventory (BDI)
BDI
A 21-item self-report measure that assesses attitudes and symptoms of depression such as feelings of guilt and hopelessness as well as physiological symptoms such as weight loss. The total score across the test is used to determine the severity of the disorder
Each item in the BDI inventory consists of
at least four statements, of which the person taking the test must choose the one that best fits how they have been feeling during a recent period of time (either in the past week or two weeks, depending on the version of the test that is being used)
An example of an item in the BDI inventory
I get as much satisfaction out of things as I used to (0)
I don’t enjoy things the way I used to (1)
I don’t get real satisfaction out of anything anymore (2)
I am dissatisfied and bored with everything (3)
what’s the minimum score needed to diagnose mild depression
10
The range of scores on BDI for moderate depression
19-29
What scores on BDI indicates severe depression
30 or more
Evaluate the BDI
-It has high validity and reliability as it is an accurate and consistent measure of depression.
-Quantitative measurement as it provides a numerical score, increasing objectivity.
-Allows clinicians to measure deterioration or improvement of depression with treatment.
-It cannot capture the detail and richness that a less structured approach could.
-Validity may be at risk as there could be response bias.
-Depressive patients may exaggerate their responses which will not be an accurate representation of how they are feeling
Issues and Debate Beck Depression Inventory: Application to Everyday Life
-Can be used to diagnose and treat depression.
-Can help identify patients with a high risk of suicidal thoughts and death.
-Adapted for use with children below age 13 who suffer from depression.
The 3 explanations for depression
- biological: genetic and neurochemical (Oruc et al., 1997)
- cognitive (Beck, 1979)
- learned helplessness/attributional style (Seligman, 1988)
The genetic explanation for bipolar disorder
-Some mental disorders are thought to have a genetic basis, meaning they can be transmitted from one generation to the next., such as in first-degree relatives like parents and siblings who share 50% of their DNA.
-Current evidence for bipolar depression suggests that there is at least some genetic explanation for why some individuals are more at risk of developing such disorders.
The neurochemical explanation for bipolar disorder
-Imbalance of chemicals affects the functioning of the brain and consequently the mood.
-Depressed individuals have low activity of serotonin and norepinephrine neurotransmitters.
