Q

BUCKLEY

A

Simultaneous presence of disorders with schizophrenia
50% depression
20% OCD

17
Q

Candidate Gene

A

Chromosomal location associated with disease

18
Q

Genetics

A

Study of genes
Carry information from one generation to another

19
Q

Neutral correlates

A

Brain activity corresponds with behaviour

20
Q

Dopamine

A

Neurotransmitter for pleasure

21
Q

Concordance rate

A

Percentage of cases where both members of a pair have a particular attribute

22
Q

Genetic counselling

A

Understanding genetic illness and how it effects family

23
Q

Polygenic

A

Phenotype influenced by more than one gene

24
Q

Superior temporal gyrus

A

Attributes stimuli to internal and external causes of schizophrenia
Activity levels are lower leading to hallucinations

25
Q

Ventral striatum

A

Anticipation of reward
Low activity on schizophrenics so loss of motivation

26
Q

Antipsychotics

A

Medication controls delusions and hallucinations

27
Q

Typical antipsychotics (first generation)

A

Severe side effects
Dry mouth
confusion
Reduced dopamine

28
Q

Atypical antipsychotics (second generation)

A

Blocks dopamine receptors
Acts on other neurotransmitters like serotonin
Addresses negative symptoms
Side effects of weight gain

29
Q

Prefrontal Cortex

A

Logical thinking
So disorganised thoughts due to low activity in schizophrenics

30
Q

Visual cortex and auditory cortex

A

Processes info received by eyes and ears
So auditory hallucinations

31
Q

Basal ganglia

A

Affects movement and thinking skills
So motor dysfunction due to larger size in schizophrenics

32
Q

Amygdala

A

Responsible for fear and lust and hunger
