What is our learning journey going to be today?

Learning Objective: to explore biological treatments for mood disorders ALL will be able to describe biological treatments for mood disorders MOST will be able to distinguish between biological treatments for unipolar and bipolar disorder SOME will be able to evaluative biological treatments in light of the explanations covered so far

Psychodynamic explanation: re-cap Oral stage  over-dependency Loss (symbolic / actual)  introjection (taking into themselves any negative feelings towards the loved one) Following this is a period of mourning – this enables a separation to be made BUT in those who are overly dependent the bonds cannot be broken and any negative feelings towards the loss turn inwards and result in depression

Psychodynamic: post-freudian Bowlby said that the most important thing was the early mother-infant relationship Bowlby’s attachment theory proposed that if a child is deprived of a warm and loving attachment in the first few years of life, depression in later life could result

Progress Measure ‘Name one type of anti-depressant and briefly describe how it works’ (3 marks)

Group Work: biological treatments for mood disorders Each group has some information on the different treatments for mood disorders Your job is to: Come up with a representation of how it works to show the rest of the class (through play-doh, drawings, role play etc) You need to be able to explain KEY INFO about how it works AND potential SIDE EFFECTS

Where the information will go: Name of anti-depressant How it works Side effects e.g. Monoamine oxidase inhibitors

Which one would you de-prioritise in the exam, why? ‘Name one type of anti-depressant and briefly describe how it works’ (3 marks) SSRIs are a type of antidepressant that selectively inhibits the reuptake of serotonin. This means that there is more serotonin in the brain and this neurotransmitter improves the depressive symptoms of unipolar depression. MAOIs are a type of antidepressant that inhibit the activity of monoamine oxidase. This means that there are higher levels of dopamine, noradrenalin and serotonin in the brain, symptoms of unipolar depression are improved. Tricyclic anti-depressants prevent noradrenalin and serotonin from being taken back into the neuron after they have been released. This means that there are higher levels of these neurotransmitters which improve symptoms of unipolar depression. Lithium returns the levels of neutotransmitters such as serotonin and dopamine to normal. It is not clear how it works but it is effective in both the depressed and manic phases. It is not effective in unipolar depression, this suggests they have a different cause. Which one would you de-prioritise in the exam, why?
