Psychological problems Flashcards
Defining mental health
Mental health is subjective so some psychologists used a mental health continuum (a way of looking at mental health by looking at it on a scale; individuals May feel more or less mentally healthy rather than being mentally healthy or not at different times and different situations
Prevalence of mental health
1/4 British adults report having been diagnosed with a mental health disorder
Each year 1/10 British children have been clinically diagnosed w a mental health disorder
The WHO estimates about 450 million people world wide suffer some form of mental health problem
LGBTQ is worst 1/10 gay or bisexual men age 16-19 had trued to take there life
Incidence of MH
increasing however this may be because of :
Changing classification
More disorders added and others eg anorexia now one but homosexuality was removed
Not all mental health diagnosed and recorded
Symptoms have been researched and changed
Many rely on self report surveys which aren’t accurate
Changes in attitude towards mental health
Changes in attitude towards mental health
1900 _ Mental health replaced mental illness
1959 _ until the mental health act (a set of laws and declarations to address issues around mental health )
1960 _ media started breaking taboo of silence
1970 _ mind campaigned for mental health rights
1980 _ rise in care but extremely underfunded
1980-1990 _ organisations and events to promote positive view of mental health
2011 _ 2 million people improved view on mental health
Stigma before vs after diagnosis
before
Person can be perceived and labelled as weird crazy or similar generally negative
After
Negative stigma can become self fulfilling prophecy (when an individual behaves in the way an assumption about them expects them to)
Discrimination before vs after diagnosis
before
Usually a lack of consideration or even rejecting from society
After
Can be stopped doing things or excluded due to there mental disorder
Effect on society
public services
More stress on health and social care survives so people have to rely on care in the community (treatment outside of hospitals in there normal communities) this leads to stress of friends and families however may help to be in comfortable environment
Law
laws have to be pug in place to stop/ limit discrimination
Attitudes
Community care could go 2 ways more exposure means more awareness or more exposure could also cause more conflict
Schizophrenia +symptoms
a psychotic disorder where people loose sense of self and reality Symptoms Thought disturbances Delusions Hallucinations Disorganised speech Catatonic behaviour Negative symptoms
Schizophrenia - statistics
prevalence - 1% of population
Sex - women (usually diagnosed in 30s) and Men(usually diagnosed in 20s) are equally effected
Recovery rates - 25% fully, 25% much improved, 25% need support, 15% hospitalised, 10%dead
Age - adult disorder that is usually diagnosed before 40s
Ethnicity - British of Caribbean and African origin higher, Asian lower
Biological theory of schizophrenia
brain function Too many dopamine receptors causing more dopamine to bind which can lead to erratic movement hallucination and delusion Brain structure Lower blood flow and smaller prefrontal cortex (control centre of brain) explains loss of psychological function Smaller hippocampus (memory and emotion) more sever = more deflated
Criticisms of biological theory of schizophrenia
By only focusing on nature the theory ignores the effect of nurture on development of schizophrenia
It is possible brain dysfunction is an effect of schizophrenia not a cause
Critics say that biological theory is too deterministic
Critics say biological theory is too reductionist
For some psychologist schizophrenia is too Broad of a label that covers a diversity of symptoms
schizophrenia research study - hypothesis +design
Hypothesis dysfunction in prefrontal cortex related to dopamine control synaptic transmission there for an agonist drug such as amphetamine should increase activity in this area design - iv_ amphetamine or not Dv_ performance on card sort test
schizophrenia research study - sample
10 patients from national institution of health in Washington each patient met the criteria for chronic depression age - 20-45 Sex - 4 F and 6 M Race - 8 White 2 black education - 8.5 - 16 years
schizophrenia research study - material and apparatus + procedure
SPECT scan, bar task, WCST test
5 did bar task first and 5 did WCST first to keep counter balance then half given amphetamine other half given placebo then tests were repeated 4 days later
schizophrenia research study - results
- amphetamine had minimal effect on supply of blood to brain at any one time
- no significant difference in bar test but WCST increase blood flow to prefrontal cortex and occipital and anterior cingulate cortices
- amphetamine had positive effect on the WCST test as more was correct
- mild behaviour changes
