syd barrett

no formal diagnosis but many believed he had schizophrenia

three clusters of schizophrenia symptoms

positive, negative, psychomotor

positive symptoms

excess or additions to a person’s thoughts, emotions or behavior

negative symptoms

loss of function; deficits of thoughts, emotion or behavior

psychomotor symptoms

unusual movements or gestures (can be excessive movements or loss of movement)

delusions

false belief that is held firmly conflicting evidence; persecution, reference, grandeur, control

hallucinations

perception-like experiences that occur in the absences of an external stimulus that may occur in any sensory modality

auditory hallucinations

sounds or voices or sounds that are perceived to be outside of one’s head

visual hallucinations

people of objects that others don’t see

tactile hallucinations

tingling, burning sensations

somatic hallucinations

something is happening inside my body

olfactory hallucinations

foul smells that others do not notice

disorganized thinking and speech

reflects disorganized thinking; tangential and “loose” associations between thoughts, unusual use / mistakes in language, inappropriate affect

poverty of speech

dramatic reduction in how much a person says and speech that is produced doesn’t have much meaning

restricted affect

minimal emotional responses and many show little emotion at all and may reflect inability to express emotions even when the individual feels them internally

apathy (avolition)

drained of energy, loss of interest in typical goals, poor follow through, social withdraw

what accounts for most of the impairment associated with schizophrenia?

negative symptoms

catatonia

marked decrease in reactivity to the environment

schizophrenia criteria

two or more of the following for at least one month: delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior, negative symptoms, signs persist for 6 months or more, functional impairment

schizophrenia onset

males= late to early teens 20s

schizophrenia risk factors present from very early in life

social dysfunction, attentional difficulties/ ADHD, quirky behaviors, odd and loose thinking

active phase of schizophrenia

meet full DSM-5 criteria with impairment

schizophrenia residual phase

some symptoms and impairment typically remain present and in many cases see some improvement in middle age

outcomes for individuals with schizophrenia

34%= supervised living

25%=living with family member

18%=supervised living

8%= nursing homes

6%= jail and prisons

5%= hospitals

5%= homeless

twin studies pf schizophrenia

80% due to genes

2nd trimester (4-6 months) during epidemic= higher rate of schizophrenia in the child

schizophrenia maternal malnutrition

1st trimester malnutrition associated with risk for schizophrenia

auditory hallucinations are associated with what area of the brain?

Broca’s area

schizophrenia has constant large deficits in

executive functions and selective attention

selective attention

atypical response to irrelevant stimuli in the environment and continue to respond strongly to the irrelevant stimulus each time it occurs

schizophrenic cerebral atrophy

enlarged ventricles, worsens across development and may slow in late adulthood

schizophrenic frontal lobe

smaller and less active; correlated with working memory and selective attention difficulties

schizophrenic cerebellum

motor dysfunction

what causes schizophrenia?

excess dopamine is one key factor but not the whole story

what other neurotransmitters play a role in schizophrenia?

serotonin, norepinephrine, glutamate, acetylcholine

traditional schizophrenia antipsychotics

block dopamine receptors, effective for positive symptoms (65% response), less effective for negative symptoms , extremely sedating, motor abnormalities that can be permanent, still significant impairment in relationships and life

second generation antipsychotics

block dopamine and serotonin receptors, more effective for negative symptoms, much lower risk for extrapyramidal motor abnormalities, very expensive, side effects may still be difficult, impairment remains for many

individual schizophrenia treatments

life skills, occupational support, social skills training, CBT, family therapy, family psychoeducation

community approaches to schizophrenia

coordinated multi-level services, brief hospitalization, supervised residences, life skill support

Criminal commitment

crime has been committed by someone who is mentally unstable at the present time and in need of treatment rather than jail

Mentally incompetent to stand trial

1. Rare that this is successful, and when it is it tends to be for a limited period of time

2. Often the defendant argues strongly against this (and may want to defend themselves, like the Unabomber)

3. if successful, wait until competent for trial

Guilty but mentally ill (14 states)

1. Doesn't change guilt

2. potential mitigating factor for sentencing

Not guilty of crime by reason of "insanity"

1. Legal term not a clinical term

2. 1955

   1. American Law Institute: not criminally responsible for a crime if

      1. Mental disorder or defect prevented from knowing right from wrong at the time of the crime

      2. Mental disorder made it impossible to control themselves and follow the law (this was later dropped)

3. 1983

   1. American Psychological Association

      1. experiencing a mental disorder at the time of a crime does not by itself mean the person was insane (again the legal term)

      2. defendant must also have been unable to determine right from wrong at the time of the crime

4. The APA guideline is now the standard for all federal cases and the majority of states

concerns about “not guilty by reason of insanity”

1. will lots of defendants try to use it to avoid punishment

2. Will the defense just hire a biased psychologist to assess the defendant and declare them not guilty?

3. Could it allow dangerous criminals to escape punishment?
