§ Describe and categorize the symptoms associated with schizophrenia
§ Discuss potential biological and environmental causes of schizophrenia
Introduction
§ Knowand about relevant neurotransmitter systems associated with schizophrenia
symptoms In individualsdifferences
§ Know about neuroanatomical with schizophrenia

schizophrenia hippocampus
and healthy
individuals and prefrontal cortex can be observed.

Historical
brain areas that show functional modulations in schizophrenia

genetic mechanisms.
§ Discuss factors that contribute to effort-based decision-making and how these are modulated in
§ Described symptoms of patients as ‘dementia praecox’:
individuals with schizophrenia
§ dementia = global disruption of perceptual and cognitive
r
processes
§ praecox = early adulthood onset
§ Main symptoms: impairments in attention, memory and goal-directed
behaviour
§ Described condition as progressive, no return to premorbid functioning
§ Disruption of perception and cognitive processes going on
Eugen Bleuler (1911):
§ Reformulated dementia praecox
§ Coined the term schizophrenia:
§ schizo = split
§ phrene = mind
§ Characterised fragmented thinking
§ Distinguished between positive and negative symptoms
§ He used the term split mind in the idea of fragmented thinking
§ Only in the cognitive symptoms of organized thinking
• What is § The first person to distinguish between positive and negative symptoms
schizophrenia?
§ Positive= symptoms that are added to behaviour
§ Negative = lack of certain behaviors
§ Can be some patients that can have strong positive symptoms but very
little negative symptoms
§ Or patients that have strong cognitive symptoms
§ Overactivity in the brain that leads to delusions
§ Hallucinations- false perceptions, can be auditory and visual
§ Disorderly thinking – disconnected and disorganized and possibly
incoherent thoughts
§ Negative symptoms cause emotion problems – lacking I certain things
e.g. lacking emotional expression and lack of experiencing pleasure
• Summary:
positive (type
, Cornell notes template
1) symptoms § Delusions: false belief despite evidence to contrary, distorting reality
(e.g. patient beliefs someone is plotting against them), but also:
§ Thought insertion
§ Thought withdrawal
§ Thought broadcasting
§ Not being in control of own actions
§ Hallucinations: perceptual experience seems real in the absence of
physical proof; most common: auditory, visual, olfactory (e.g. seeing a
person or an animal that is not real)
§ Disorganized behaviour (e.g. can affect speech, difficulties with routine
tasks, inappropriate emotions)
§ Delusions – the feeling of not being in control of your own actions, the
feeling of being controlled by someone or something else
§ Fletcher and Frith, 2009
• Summary:
negative (type
2) symtpoms Recent suggestion: 2 subdomains of negative symptoms (Lim et al.):
Diminished emotional expression
§ Affect: blunted affect, mood or emotional state, limited range of
emotions
§ Alogia: poverty of speech, lack of conversation
Avolition
§ Apathy (lack of motivation)
§ Social withdrawal
§ Anhedonia: inability to feel pleasure
• Summary
cognitive
deficits § Substantial impairment in overall cognitive performance (most
individuals)
§ Can be variable (either selective or general)
§ Most common deficits in:
§ Executive functions/cognitive control (incl. verbal fluency and
