Chapters 7 & 8: Depressive & Bipolar Disorders & Treatment Flashcards
Unipolar depression
Depression without a history of mania. Have no history of mania and return to a normal or nearly normal mood when their depression lifts
Symptoms of unipolar depression
- Emotional: feel sad and dejected, miserable, empty, Anhedonia (inability to experiences any pleasure at all), anger, anxiety, agitation
- Motivational: typically lose the desire to pursue their usual activities, lack of drive
- Behavioral: usually less active and less productive, may move and speak more slowly
- Cognitive: hold extremely negative views of themselves (inadequate, undesirable, inferior, and perhaps even evil), blame themselves
- Physical: physical alignments such as headaches, indigestion, constipation, dizzy spells, general pain, disturbances in sleep/appetite
Major depressive disorder
- A severe pattern of depression that is disabling and is not caused by such factors as drugs or a general medical condition
- Associated Symptoms: seasonal (changes with seasons), catatonic (marked by either immobility or excessive activity), peripartum (occurs during pregnancy or within 4 weeks of giving birth), melancholic (if person is almost totally unaffected by pleasurable events)
Persistent depressive disorder
- A chronic form of unipolar depression marked by ongoing and repeated symptoms of either major or mild depression
- Associated Symptoms: some people have repeated major depressive episodes, a pattern technically called persistent depressive disorder with major depressive episodes. Others have less severe and less disabling symptoms, a pattern technically called persistent depressive disorders with dysthymic syndrome
Premenstrual dysphoric disorder
A disorder marked by repeated episodes of significant depression and related symptoms during the week before menstruation
Bipolar I disorder
- A type of bipolar disorder marked by full manic and major depressive episodes
- Most of them experience and alternation of the episodes (e.g., weeks of mania followed by a period of wellness, followed in turn by an episode of depression), some have mixed features, which they display both manic and depressive symptoms within the same episode (e.g., having racing thoughts amidst feelings of extreme sadness)
Bipolar II disorder
- A type of bipolar disorder marked by mildly manic (hypomanic) episodes and major depressive episodes
- Some people with this pattern accomplish huge amounts of work during their mild manic periods
Cyclothymic disorder
A disorder marked by numerous periods of hypomanic symptoms and mild depressive symptoms
Dysthymic Disorder and Symptoms
- Less severe but more chronic depression
- Depressed mood plus 2 additional symptoms (Poor appetite/overeating, Insomnia or hypersomnia, low energy or fatigue, low self-esteem, poor concentration or difficulty making decisions, Feelings of hopelessness)
- A mild but long-term form of depression. Defined as a low mood occurring for at least 2 years, along with at least 2 other symptoms of depression. Examples of symptoms include lost interest in normal activities, hopelessness, low self-esteem, low appetite, low energy, sleep changes, and poor concentration
What is meant by bipolar disorder?
People with bipolar disorder experience both the lows of depression and the highs of mania. Many describe their lives as an emotional roller coaster, as they shift back and forth between extreme moods. A number of sufferers become suicidal. ~ 10% - 15% of them eventually end their own lives, usually out of a sense of hopelessness. Their roller-coaster ride also had a dramatic impact on relatives and friends, and tend to experience depression and mania over the years
Psychodynamic Depressive Explanation
- . According to theorists, a series of unconscious processes is set in motion when a loved one dies, unable to accept the loss, mourners at first regress to the oral stage of development, the period of total dependency when infants cannot distinguish themselves from their parents. By regressing to this stage, the mourners merge their own identity with that of the person that have lost, and so symbolically regain the lost person, a process called introjection (they direct all their feelings for the loved one, including sadness and anger toward themselves)
- Symbolic or Imagined Loss: in which a person equates other kinds of events with the loss of a loved one. The loss of a valued object (e.g., loss of employment) that is unconsciously interpreted as the loss of a loved one
- Object Relations Theorists: propose that depression results when people’s relationships – especially their early relationships – leave them feeling unsafe, insecure, and dependent on others
Cognitive-Behavioral Depressive Explanation
- Cognitive-behavioral theories contend that unipolar depression results from a combination of problematic behaviors and dysfunctional ways of thinking
- Behavioral Dimension: Peter Lewinsohn linked depression to significant changes in the number of rewards and punishments people receive in their lives = the positive features in their lives decrease even more, and the decline in rewards leads them to perform still ewer constructive behaviors and in this manner, spiral towards depression. Lewinsohn and other theorists have further proposed that social rewards are particularly important in the downward spiral of depression
- Negative thinking: Aaron Beck believes that negative thinking, rather than underlying conflicts or a reduction in positive rewards, lies at the heart of depression. According to Beck, maladaptive attitudes, a cognitive triad, errors in thinking, and automatic thoughts combine to produce unipolar depression
- Learned Helplessness: A Cognitive Behavioral Interplay: according to psychologist Martin Seligman, feelings of helplessness are at the center of depression. People become depressed when they think (1) they no longer have control over the reinforcements (rewards and punishments) in their lives (2) that they themselves are responsible for this helpless state
Biological Depressive Explanation
- Genetic factors (e.g., suggest that some people inherit a predisposition to unipolar depression) use family pedigree studies = select people with unipolar depression, examine their relatives, and see whether depression also afflicts other members of the family.
- Biochemical factors, low activity of 2 neurotransmitter chemicals, norepinephrine (a neurotransmitter whose abnormal activity is linked to depression) and serotonin (a neurotransmitter whose abnormal activity is linked to depression)
- Brain Circuits: point to several brain structures that are likely members of this circuit, including the prefrontal cortex, hippocampus, amygdala, and subgenual cingulate (A.K.A. Brodmann Area 25), several of these structures in this circuit are also members of the brain circuits that contribute to certain anxiety disorders and PTSD. However, the subgenual cingulate, a subregion of the brain’s anterior cingulate cortex, is distinctly part of the depression-related circuit
- Immune System: when people are under intense stress for a while, their immune systems may become dysregulated, leading to slower functioning and important white blood cells called lymphocytes and to increased production of C-reactive protein (CRP), a protein that spreads throughout the body and causes inflammation and various illnesses = immune system dysregulation of this kind helps produce depression
Sociocultural Depressive Explanation
- Sociocultural theorists propose that unipolar depression is strongly influenced by the social context that surrounds people. Their belief is that depression is often triggered by outside stressors
- The family-Social Perspective: the same perspective as cognitive-behavioral theorists, believe that a decline in social rewards is particularly important in the development of depression. The social contact and rewards of depressed people decrease, and, as they participate in fewer and fewer social interactions, their social skills deteriorate even further
Biological Bipolar Explanation
- Neurotransmitters: ties between bipolar disorder and abnormal activity of other neurotransmitters, such as GABA, the brain chemical
- Ion Activity: irregularities in the transport of these ions may cause neurons to fire too easily (resulting in mania) or to stubbornly resist firing (resulting in depression)
- Brain Structure: brain imaging and postmortem studies have identified a number of abnormal brain structures in people with bipolar disorders
- Genetic Factors: people inherit a biological predisposition to develop bipolar disorders
Psychodynamic Depressive Treatments
Believing that unipolar depression results from unconscious grief over real or imagined losses, compounded by excessive dependence on other people, psychodynamic therapists seek to help clients bring these underlying issues to consciousness and work through them. they encourage a depressed client to associate freely during therapy; suggest interpretations of the client’s associations, dreams, and displays of resistance and transference; and help the person review past events and feelings
Cognitive-Behavioral Depressive Treatments
- On the behavioral side, they seek to get the clients moving again – to engage in and enjoy more activities
- On the cognitive side, they guide clients to think in more adaptive, less negative ways
- Use behavioral activation & cognitive therapy
Biological Depressive Treatments
Usually, biological treatment means antidepressant drugs or popular alternatives such as herbal supplements, but for people whose depression does not respond to medications, psychotherapy, or the like, it sometimes means brain stimulation
Sociocultural Depressive Treatments
- designed to address the unique issues faced by members of cultural minority groups. Therapists typically have special cultural training and a heightened awareness of their client’s cultural values and the culture-related stressors, prejudices, and stereotypes that their clients face. Therapists make an effort to help clients develop a bicultural balance and to recognize the impact of their own culture and the dominant culture on their views of themselves and their behaviors.
- Family-Social Treatments: therapists who use family and social approaches to treat depression help clients change how they deal with the close relationships in their lives.
Cognitive-Behavioral Bipolar Treatments
- Many clinicians now use individual, group, or family therapy as an adjunct to mood-stabilizing drugs
- therapists use these formats to emphasize the importance of continuing to take medications; to improve social skills and relationships that may be affected by bipolar episodes; to educate patients and families about bipolar disorders; to help patients solve the family, school, and occupational problems caused by their disorder; and to help prevent patients from attempting suicide
Biological Bipolar Treatments
- Lithium: a metallic element that occurs in nature as a mineral salt and is an effective treatment for bipolar disorders
- Mood Stabilizing Drugs: psychotropic drugs that help stabilize the moods of people suffering from bipolar disorder (A.K.A. antibipolar drugs)
Antidepressant Drugs
- MAO Inhibitors: an antidepressant drug that prevents the action of the enzyme monoamine oxidase
- Tricyclics: an antidepressant drug such as imipramine that has 3 rings in its molecular structure
- Second-Generation Antidepressants: Selective Serotonin
- Reuptake Inhibitors (SSRIs): a group of second-generation antidepressant drugs that increase serotonin activity specifically, without affecting other neurotransmitters
Brain Stimulation
biological treatments that directly or indirectly stimulate certain areas of the brain
Electroconvulsive Therapy (ECT)
a treatment for depression in which electrodes attached to a patient’s head send an electrical current through the brain, causing a convulsion
