genetic explanation of unipolar depression
How the influence of genes can explain why some people depression

A

➜ Evidence if someone in your family has been diagnosed w/ unipolar depression, higher risk you’ll also be diagnosed w/ depression.

➜ Depression might be inherited through genes.

Hyde et al. (2016) = 17 diff gene variations linked to depressions

Q

twin studies on influence of genes for depression

A

➜ Monozygotic twins = share 100% of the same genes.
➜ Dizygotic twins = share 50% of the same genes.

McGuffin et al. (1996)
Monozygotic twin depressed = 46% co-twin becomes depressed.

Dizygotic twin depressed = 20% co-twin becomes depressed.

Shows depression might be genetic.

  • process by which
  • neurons reabsorb neurotransmitters
  • that they release.
25
Q

define serotonin

Q

antidepressants

Selective serotonin reuptake inhibitors SSRIs

A

  • allows other neurons to absorb it
  • serotonin available for longer
  • helps increase levels of serotonin in brain, improving mood.
27
Q

antidepressants

antidepressants

monoamine oxidase inhibitors (MAOIs)

  • improves mood
29
Q

antidepressants

tricylics TCAs

A
  • around since 1950s
  • boost effect of serotonin & noradrenaline
  • prevent reabsorption of neurotransmitters into neuron
  • longer to act on the brain
  • mood enhancing effect lasts longer
30
Q

define placebo

A

inactive substance or fake pill used instead of active substance. person given placebo wont know its fake.

31
Q

define relapse

Q

A

Strengths

  • Improves symptoms; makes it easier for patients to access other psychological therapies.
  • Royal College of Psychiatrists; 65% of patients w/ moderate-severe symptoms of depression showed improvements when given antidepressants then compared to 30% given a placebo.

Weaknesses
* Unpleasant side effects; MAOIs dangerous when eaten with certain foods.
Some can cause side effects such as nausea, suicidal thoughts, diabetes.
* Only tackle symptoms, and not the cause. Long-term effect is less likely, more likely to relapse.
