Depression II Flashcards
What do most theories about the development of depression involve?
Cognitive vulnerability x stressful life events = depression.
In schema theory, life is constantly being interpreted through a negative lens. How does this support one of the main risk factors of Major Depression?
Constantly interpreting life in a negative way provides more and more evidence to support negative schema. Thus, a person is more likely to have a depressive relapse (% increase after each episode).
Interpersonal relations are considered very important in the causation/maintenance of depression. What are some ways a person with depression might reduce contact from friends?
Having limited eye contact, lowered speech, lack of reaction/interest in other people. Regularly disclosing negative information, displaying negative facial expressions.
How does Stress-Generation Hypothesis interpret the control people have over life events?
While there are some life events that are out of our control, there are many under our influence. Depressive people tend to generate more negative life events that are dependant on how they behave (job loss, relationship breakdown, etc.).
Theories on the cause/maintenance of depression show that depression is insidious, whereby it ___ .
Maintains and exacerbates itself, each time becoming stronger and stronger.
What was the first effective treatment for depression and when/what for was it introduced?
Electroconvulsive Therapy (ECT) was first introduced in 1938 to treat schizophrenia.
How does ECT work? What is its course and how effective is it?
It works by applying a brief electrical current to the brain that induces a temporary seizure. After 6-10 treatments mood will normally lift. It is 85% effective for those with severe depression.
Are there side effects for ECT? How often is it used and is it effective in the long-term (after the course is finished)?
The main side-effect is short term memory loss. It is only used sparingly, as a last resort for those with severe depression because we still don’t know how it works. Relapse after treatment is common.
What treatment for Major Depression came after ECT? What do they have in common?
Three waves of drug treatments. They are equally effective and once stopped, relapse usually occurs within 6-8 months.
What was the first wave of drug treatment? When was it introduced and what for?
Monoamine Oxidase Inhibitors (MAOIs) was introduced in 1956 to treat tuberculosis.
What was the second wave of drug treatment? When was it introduced and what for?
Tricyclic Medications were introduced in the early 1960s to treat psychosis.
What was the third wave of drug treatment? When was it introduced?
Selective Serotonin Reuptake Inhibitors (SSRIs) were first introduced in the 1980s.
How do Monoamine Oxidase Inhibitors (MAOIs) work?
They break down/block Monoamine Oxidase A & B, increasing the availability of Serotonin and Norepinephrine.
How do Tricyclic Medications work?
They block the reuptake of Serotonin and Norepinephrine.
How do SSRIs work? What are two similar but alternative medications?
SSRIs block the reuptake of Serotonin, there are also SNRIs (Serotonin and Norepinephrine Reuptake Inhibitors) and NDRIs (Norepinephrine and Dopamine Reuptake Inhibitors).
What are some serious side effects when prescribing MAOIs? What needs to be avoided when taking MAOIs?
Blocking MAO-A & -B cause serious side effects, such as hypertension, the patient must avoid Tyramine (beer, red wine, cheeses). Taking this medication increases the likelihood of death.
What should be considered when prescribing MAOIs?
Only prescribing MAOIs that inhibit MAO-A, as inhibiting MAO-B is more risky.
What are some minor side effects of Tricyclic Medications and what is a big risk that needs to be considered/monitored?
They are anti-cholinergic drugs so induce dry mouth, blurred vision, tremor, etc. Around the 10th-14th day, the risk of suicide increases, as the vegetative symptoms lift first but mood is still low.
Tricyclic Medications are a type of drug that is risky when prescribing to depressed people, what kind of drug is that?
They are cardiotoxic, meaning they can be used for suicidal overdose.
