Maladaptive behaviour
- cannot adapt to normal daily life.
- a threat to self and others
Define: mental disorder
- a clinically significant disturbance in cognition,emotion regulation or behaviour
- usually associated with significant distress or disability.
Demonic Possession
- symptoms of psychopathology result from being possessed by evil spirits.
- treated by exorcism
Trephination
boring a hole into the skull to release demons responsible for abnormal behaviour.
The Four Humors
Hippocrates believed that illnesses of the body and mind have natural causes. Galen proposed the links between temperament based on the four humours. Phlegm, Black bile, yellow bile, blood.
Phlegm
Phlegmatic: calm, unemotional, lethargic
Black bile
Melancholic: despondent, sleepless, irritable.
Blood
Sanguine: confident, optimistic
Yellow bile
Choleric: easily angered, bad tempered.
Philippe Pinel (1745-1826)
stopped harsh practices of asylums. Used talking, understanding and concern
Moral Treatment (Quaker Movement)
- abandoned medical practices.
- understanding, hope and moral responsibility
- occupational therapy
General paresis
psychological symptoms include personality changes, mood changes and dementia
(caused by syphilis)
Milieu therapy (1950s-1970s)
- supportive environment
- provides a sense of belonging, care and accountability
- vocational and recreational activities
- more likely to be discharged
- less likely to relapse.
Token Economy (1950s-1970s)
- based on operant conditioning
- rewarded with tokens for desirable behaviour
- promote social skills, independence and self-care
- patients discharged sooner
- use has declined since 1980s
- because people have a right to basic items previously used as reinforcers
- not always practical at maintaining positive behaviour after being discharged
Community Care
- enabling people to remain in their homes and be independent
- outpatient therapy
- daily living support
- day centres
- employment services
- peer support
The Biological Model - Genetics
Diathesis (inherited predisposition or vulnerability to developing a disorder) + stress (environmental) = psychological disorder
Frontal lobe in depression
decreased activation in prefrontal cortex - linked to goal attainment
Hippocampus in depression
fear related stimuli
deficits- dissociating affective responses from context - eg feel sad independent of context
Amygdala
fear response and emotional memory
- increased activation- prioritising threatening info and interpreting it negatively
Neurotransmitter used in mood disorders
serotonin and norepinephrine
Neurotransmitter used in anxiety disorders
norepinephrine and GABA
Neurotransmitter used in schizophrenia
dopamine
Neurotransmitter used in Alzheimer’s
acetylcholine
Critique of Biological model
- assumes something is ‘broken’ but the symptoms may be an extreme of normal behaviour
- the dysfunction is located within the individual
- ignores socio-economic and enviro factors
- cannot explain dysfunctional thoughts and beliefs
- stigmatising (self and other)
- person adopts a ‘sick role’
The purpose of classification
- creates a common language for research and data sharing
- understands the causes of psychopathology
- develop effective treatment and prevention strategies
- assess the effectiveness of treatments
- organise services and support
- medical aid
Problems with classification
- labels can be stigmatising
- encourages adoption of a ‘sick role’
- defines disorders as discrete entities (have it or you don’t)
- high rates of comorbidity

DSM-5 Cultural Consideration Aims
- enhance the cross-cultural applicability of the DSM
- increase awareness of the challenges involved in using the DSM to evaluate people from diverse cultures
- acknowledges the cultural differences in symptom presentation, expression of distress, course and prevalence
- avoid misdiagnosis
