Therapy- drug therapy

Question 1

What are the aims of drug therapy?

Answer 1

States that behaviour is due to our biological makeup
-Aims to manipulate a patients bodily process, with the goal of reducing the symptoms of their mental health disorder

Question 2

MH schizophrenia drug therapy?

Answer 2

Caused by excess dopamine within the brain, leading to symptoms like hallucination and delusion

Question 3

MH depression drug therapy?

Answer 3

Lack of serotonin so patients in a low mood and lacking desire to engage in activity’s they would usually find joy in

Question 4

MH anxiety drug therapy?

Answer 4

Caused by an imbalance of the emotional centres within the brain leading to overproduction of adrenaline (noradrenaline) and often a fight or flight response when they are in no real danger

Question 5

Component 1 of drug therapy?

Answer 5

Antipsychotic drugs

Question 6

C1- 2 type antipsychotic drugs?

Answer 6

-Conventional
-Atypical

Question 7

C1- how do conventional drugs work?

Answer 7

Schizophrenia is believed to cause excess of dopamine in the brain
-The medication binds to dopamine receptors in the brain and blocks the dopamine receptors but not stimulating them
-This reduces the flow of dopamine within the brain

Question 8

C1- Side effects?

Answer 8

Tiredness
Feeling woozy
Constipation
Difficulting weeing
Dry mouth
Stuffy nose
Lightheadedness
Tradiv Dyskinesia (uncontrollable movements)

Question 9

C1- examples of conventional drugs?

Answer 9

Chlorpromazine
-Haldol (haloperidol)
-Loxatine (loxapine)

Question 10

C1- What is atypical, how do they work?

Answer 10

-These work in a similar way, however, only temporarily blocking dopamine receptor sites
They will then dissociate to allow for normal dopamine flow
-Because this is more temporary, side effects are less prevalent

Question 11

C1- Atypical, example of these?

Answer 11

Clozaril
Abilify (aripiprazole)

Question 12

C1- Side effects of atypical?

Answer 12

Drooling
Drowsiness
Dizziness
Light headed
Shaking
Constipation
Tardiv Dyskena, less common movements only temporary

Question 13

What is component 2?

Answer 13

Antidepressant drugs

Question 14

C2- what are these called?

Answer 14

Selective-serotonin reuptake inhibitors

Question 15

C2- How do these work?

Answer 15

Lack of serotonin in the brain
-When someone doesn’t have depression is constantly being released and absorbed at the synapse constantly
-SSRIs work by binding to postsynaptic receptors in the euron
2)Stops the reuptake of serotonin so less is absorbed
3)Allow our serotonin to build up in the synaptic cleft, allowing more available in the blair

Question 16

C2- Examples of antidepressant?

Answer 16

Sertraline
Prozac

Question 17

C2- Side effects of sertraline?

Answer 17

-Nausea
-Headache
-Sleep struggles
-Diarrhea
-Dry mouth
-Dizziness
-Tiredness/weak

Question 18

C2- side effects of prozac?

Answer 18

-Anxiety
-Diarrhea
-Nausea
-Headache
-Seizure
-Drowsiness

Question 19

What is component 3?

Answer 19

Antianxiety drug

Question 20

C3- what are the 2 antianxiety drugs?

Answer 20

Benzodiazepines BZs
Beta-Blockers BB’s

Question 21

C3- How do Benzodiazepines BZs work?

Answer 21

-Instead of targeting serotonin or dopamine receptors, they calm the body’s stress response
(Slow heart rate, decreased bp, cool temp)
-Slows the CNS by enhancing the activity of GABA (relieves stress)

Question 22

C3- Benzodiazepines BZs side effects?

Answer 22

-Drowsiness
-Lightheadedness
-Confusion
-Unsteadiness
-Dizziness
-Slurred speech
-Muscle weakness
-Memory loss

Question 23

C3- how do Beta-Blockers BB’s?

Answer 23

-These work by binding to receptors on the cells on the area of the body that become aroused e.g. the heart
-BB block the receptor on the cells, slowing function
-So leads to slower heartbeat and low blood pressure so less anxiety

Question 24

C3- side effects Beta-Blockers BB’s?

Answer 24

-Tiredness
-Dizziness
-Cold fingers or toes
-Difficult sleep/nightmare
-Difficulty getting sexually aroused
-Feeling sick

Question 25

Applying assumption to the therapy- neurotransmitter?

Answer 25

BA- says that neurotransmitters can control our moods, feelings, perception and behaviour so when there is a imbalance, such as depression means a lack of serotonin
Drug therapy applies to this as SSRIs aim to treat depression by inhibiting the re uptake of serotonin within the brain leaving an abundance of neurotransmitters within the brain therefore increasing its effects, so reducing symptoms of depression

Question 26

Applying assumption to the therapy- Localisation of function?

Answer 26

Specific parts of the brain which have specific functions
E.g. limbic system (the emotion centre), when there are disturbances here it can effect our mood leading to illness. Drug therapy works by targeting specific areas of the variance and aim to reduce symptom. E.g. anti anxiety medication (BZ) targets the limbic system within our brain which slows the CNS, so reducing symptoms of anxiety by slowing heart rate

Question 27

Applying assumption to the therapy- Evolutionary influence?

Answer 27

-In cave man era we needed anxiety to help us survive, so ultimately this is passed through generations
-Genetics play a part in mental heath as it can be inherited and we learn from ancestors, so we treat mi with physical precaution and like physical problem
