The usual model of schizophrenia has a pathophysiology that is synonymous with abnormal regulation of (blank). What tells us that this may not be true?

A

dopamine

-dopaminergic agents may not always solve the problem, other neurotransmitters may be involved, just because some dopamine agonist work doesnt mean that it works because schizophrenics lack it

aspects of pathophysiology

obsessive-compulsive syndrome was a risk factor for subsequent schizophrenia

A

T

47
Q

What are four neuropsychiatric syndromes that are related to schizophrenia?

A
  • neurological signs*
  • dyskinetic movements*
  • oculomotor dysfunction*
  • polydipsia
  • Increased prevalence of these symptoms in first degree relatives who do not have schizophrenia
48
Q

T or F

The presence of a “comorbid” syndrome is so common as to be the rule rather than the exception in schizophrenia

A

T

49
Q

Comorbid syndromes with schizophrenia probably share what?

A

environmental risk factors and common biology

50
Q

People w/ schizophrenia are dying earlier of (blank) except what 2 things? What could be the cause?

A

everything
stroke and cancer
accelerated aging

51
Q

People with schizophrenia have anatomical (blank) compared to the general pop. (i.e head, eyes, ears, mouth, hands feet THey are also slightly (Shorter/taller) and (thinner/fatter)

A

differences

short and thinner -> small body mass index (BMI)

52
Q

People with psychosis have what kinds of glucose regulation?

What about siblings of schizophrenic patients that do not have schizophrenia?

A

People with schizophrenia have impaired glucose tolerance and pre-diabetes

The also have impaired glucose tolerance and pre-diabetes

**For schizophrenics and schizophrenic siblings: Both normal at baseline but after 2 hours have impaired glucose

53
Q

What is the blood pressure like in schizophrenic patients?

A

increased BP so increased prevalence of vascular disease

54
Q

Patients with schizophrenia have decreased (blank) which is associated with accelerated aging

A

androgen (decreased free testosterone in males) and telomere content

55
Q

Durign exacerabation of schizophrenia, what cytokines increase?

A

IL-1B
IL-6
TGF-beta

56
Q

What are trait markers of schizophrenia (are elevated even when there is not exacerabation)?

A

IL-12
IFN-y
TNF-a
sIL-2R

57
Q

Whats up with stem cells of schizophrenic patients?

A

abnormal signaling for adult circulating stem cells (mesenchymal stem cells)

58
Q

What is the main chemokine that controls the movement of adult circulating stem cell?
What pathophysiology messes with this?

A

Stromal-derived factor 1-alpha (SDF1-alpha)
diabetes (and diabetes is hella prevalent in schizophrenics)
and schizophrenics

59
Q

What is this:
Cells with broad differentiation potential
Involved in normal repairs processes
Reside much of the time in the bone marrow, but can be mobilized and localized to other organs

A

adult circulating stem cells

60
Q

What are the abnormalities of the brain shown in schizophrenics?

What does this tell us?

A
  • decreased volume of brain
  • decreased neuropil
  • decreased volume of neurons
  • increased densitiy of neurons
  • decreased number of neurons
  • increased dopamine release
  • abnormal expression of NMDA receptor subunits
  • decreased white matter volumes with abnormal orientation of fibers

That schizophrenia is not a neurodegenerative disease it is an abnormal development -> thus you just make less neurons and less synapses and less NMDA receptors

61
Q

Administration of what three drugs can cause a mild increase in psychotic symptoms in people with schizophrenia?

A
  • cannabis
  • serotonin agonist
  • NMDA antagonist
62
Q

What are the tx’s for schizophrenia?

A
  • antipsychotics
  • tx for other neuropsychiatric syndormes (depression, anxiety)
  • psychosocial tx
63
Q

Does psychoeducation work and what is it?

A
  • yes, it reduces relapse

- educating the person about the illness

64
Q

T or F

schizophrenia isnt a psychotic disorder

A

T

It is a disorder of essentially every brain function

65
Q

T or F

Schizophrenia isn’t a brain disorder;

A

T

it is a disorder of the entire body in which psychosis is present

66
Q

T or F

It is misleading to consider neuropsychiatric syndromes such as abnormal movements “comorbid” with schizophrenia;

A

T

they are part of the disorder

67
Q

T or F
equate schizophrenia with dopamine dysregulation because psychosis responds (variably) to dopamine antagonists is like saying bubonic plague is a disease of aspirin insufficiency.

A

T

schizophrenia responds to dopamine, it isnt caused by dopamine depletion

68
Q

What is the purpose of care for schizophrenia?

A
  • To improve & maintain quality of life
  • To extend life
  • To deal with disability, discomfort or death
69
Q

(blank) is a behavioral treatment that uses drill and practice, compensatory and adaptive strategies to facilitate improvement in targeted cognitive areas like memory, attention and problem solving.

A

Cognitive remediation

70
Q

Does Cognitive remediation work for schizophrenics?

A

yes a little bit in:

general cog, social cog, verbal memory, working memory, attention, processing speed, real-life function

71
Q

(blank) is the critical, hostile, and emotionally over-involved attitude that relatives have toward a family member with a disorder.

What does this behavior increase?

How do you reduce this behavior and what happens if you do reduce this?

A

Expressed emotion

Risk of relaspse

Family interventions

  • decrease frequency of relapse
  • reduce hospital admission
  • increase med adherence
  • increase general social function
