Etiology
- specific etiology unknown
- dopamine hypothesis
- hypoactive dorsolateral prefrontal cortex (DLPFC)
- hyperactive limbic system dopaminergic neurons
- adolescence triggers onset of symptoms secondary to the need to use DLPFC dopaminergic neurons as higher cognitive functions develop
- pharmacologic precipitants:
- risk factors
- paternal age[17]
- substance abuse
- urban residence
- trauma
- social adversity
- cognitive impairment
- daytime napping[50]
- pregnancy & developmental complications[43]
- gestational diabetes
- emergency C-section
- abnormal fetal development & low birth weight
- preeclampsia
- maternal malnutrition & vitamin D deficiency
- Toxoplasma gondii infection may be a contributing factor[39][42]
Epidemiology
- 1% per lifetime, affects about 1 in 300 people worldwide[45]
- men & women equally affected
- late onset (age > 45) women > men[4]
- severity may be less in women than men*
- women > 45 years have the greatest risk of hospitalization for relapse[45][46]
- average age of onset:
- 15-30 years: late teens to early adulthood[43]
- worldwide distribution with similar prevalence
- higher social class at birth associated with increased risk[6]
* estrogen with antidopaminergic effect[43]
Pathology
- the hippocampus & its CA1 subdivision is the brain region affected first & foremost in schizophrenia[44]
- loss-of-function mutations in subunits of AMPA receptors & NMDA receptors
- hyperactive limbic system dopaminergic neurons
- compensatory response to hypoactive DLPFC dopaminergic neurons
- thought to account for active phase (positive symptoms) of schizophrenia
- hypoactive dorsolateral prefrontal cortex (DLPFC)
- hypoactive dopaminergic neurons secondary to problems in migration of neural tissue during development
- thought to account for chronic phase (negative symptoms) of schizophrenia
- alterations of mGluR3 receptors in the DLPFC might have a role in the pathogenesis of schizophrenia; schizophrenia subjects had lower mGluR3 than controls & had higher levels of glutamate carboxypeptidase-2, an enzyme that metabolizes N-acetylaspartylglutamate, the only known specific endogenous agonist of mGluR3[10]
- adolescence triggers onset of symptoms secondary to the need to use DLPFC dopaminergic neurons as higher cognitive functions develop
Genetics
- often family history
- schizophrenia susceptibility
- chromosomal translocation t(9;14)(q34;q13) involving NPAS3 is found in a family with schizophrenia
- chromosomal translocation t(1;11)(q42.1;q14.3) involving DISC1 segregates with schizophrenia & related psychiatric disorders in a large Scottish family
- overexpression of RIC3 in brains from patients with bipolar disease or schizophrenia
- human endogenous retrovirus HERV-W antigenemia more common in patients than controls[9]
- associated with variations in CACNA1C & CACNB2[18]
- 108 linked genetic loci[22]
- other implicated genes:
Clinical manifestations
- active phase, psychosis (positive symptoms)
- 1st psychotic episode usually occurs at age 14-30 years[43]
- psychotic episodes present for at least 1 month
- hallucinations:
- usually auditory hallucinations
- multimodal hallucinations common with late-onset schizophrenia
- delusions
- often persecutory delusions, common with late-onset schizophrenia
- often bizarre rather than plausible delusions
- disorganized speech
- disorganized or catatonic behavior
- chronic phase (negative symptoms)
- present for at least 6 months
- cataplexy
- flat affect
- poverty of speech, alogia
- lack of initiative, apathy, anhedonia
- social isolation, social withdrawal
- cognitive dysfunction (distinct from negative symptoms)[43]
- poor job performance, avolition
- poor hygiene
- unusual perceptions
- mood symptoms:
- no mania, no depression vs unusual expression of depression[43]
- functional impairment
- suicidal attempts in 50%; 10% are successful
- mental status
- usually alert & oriented without fluctuations in level of consciousness
- motor activity variable
- memory often impaired (less so in late onset form)[4]
Diagnostic criteria
- 2 of the following:[12]
- delusions, hallucinations, disorganized speech, disorganized or catatonic behavior, negative symptoms
- at least 1 functional impairment:[12]
- occupation, social interactions, self care
- duration of >= 6 months with >= 1 month of active symptoms[12]
- continuous signs of disturbance[43]
- disorders in differential diagnosis ruled out
Laboratory
- tests of exclusion
- CBC/WBC count if clozapine is used to monitor for potential agranulocytosis
- not routine
- therapeutic drug monitoring of serum antipsychotic levels[29]
- 1/3 of patients referred for treatment-resistant schizophrenia in the UK with low or no plasma antipsychotic
- see ARUP consult[2]
Diagnostic procedures
- mental status exam
- EEG: frequently left sided abnormalities (non-specific)
Radiology
- CT of head: ventricular enlargement 10-50% (non-specific)
- PET scan: decreased frontal lobe metabolism
- MRI neuroimaging:
- may show periventricular hyperintensities (late onset)[4]
- functional imaging & MRI demonstrates a dysfunctional hippocampus characterized by abnormal increases in glutamate levels, hyperactivity, & atrophy[44]
Complications
- increased risk of mortality
- increased risk of diabetes mellitus, obesity
- adverse outcomes at 30 days after surgery
- poor communication skills may play role[19]
- health care costs for patients with chronic diseases & schizophrenia are particularly high[31]
- early onset dementia, 28% at age 66 years[38]
- frequent comorbidity of depression* with high risk of suicide in elderly with schizophrenia[15][41]
* elderly with chronic schizophrenia may grapple with Erikson's final stage of psychosocial development-integrity vs despair; they may find themselves in a state of despair; this is diagnosed as major depression with schizophrenia in later life[15]
- disease interaction(s) of schizophrenia with breast cancer
- disease interaction(s) of hyperlipidemia with schizophrenia
Differential diagnosis
- substance abuse
- schizophreniform disorder (symptoms < 6 months)
- psychosis (symptoms < 1 month, > 1 day)
- schizoaffective disorder
- mood disorder with psychotic symptoms
- psychosis brief compared with mood symptoms
- bipolar disorder with psychotic features[43]
- delusional disorder: delusion without other symptoms of schizophrenia
- personality disorder
- paranoid
- borderline
- schizoid
- schizotypal
- Huntington's diesase
- Wilson's disease
- temporal lobe epilepsy
- heavy metal poisoning
- Werneke-Korsakoff syndrome
- HIV
- syphilis
- herpes encephalitis[12]
* 22% of patients initially diagnosed with schizophrenia have their diagnoses changed during subsequent hospitalizations[12]
Management
- improving activities of daily living is central to any meaningful intervention in schizophrenia[30]
- bundling medication with psychosocial therapy improves outcomes[24]
- pharmacologic agents
- long-acting injectable antipsychotic agents may be superior to oral agents in reducing rehospitalization for older[33][40] & younger[47] patients without an increase in adverse events[45][47]
- atypical antipsychotic agents
- combined dopamine & serotonin receptor blockade
- fewer extrapyramidal symptoms than other antipsychotic agents
- clozapine (Clozaril) reduces mortality[11]
- most effective but requires routine CBC/WBC count for potential agranulocytosis[12]
- most effective antipsychotic in preventing relapse & reducing risk for substance use disorder[51]
- least likely to cause extrapyramidal symptoms[12]
- risperidone (Risperdal)[5]
- decrease risperidone for parkinsonism & tardive dyskinesia prior to switching to clozapine (GRS11)[15]
- olanzapine: weight gain, substantial[48]; greatest among antipsychotics[49]
- olanzapine > quetiapine > risperidone > aripiprazole[48]
- in adolescents 8.5 kg after 11 weeks of therapy[48]
- other atypical antipsychotics not as effective as olanzapine or risperidone for core symptoms[28]
- high potency antipsychotic agents
- dopamine D2 receptor antagonist
- pharmaceutical agents
- dosage: 5-30 mg
- extrapyramidal side effects
- preferred agents during pregnancy
- low potency antipsychotic agents
- dopamine D2 receptor antagonist
- pharmaceutical agents
- dosage: 300-1000 mg
- anticholinergic side effects
- 2/3 of patients relapse within 6 months after discontinuation of antipsychotic
- changing an effective & well-tolerated regimen is not recommended
- muscarinic receptor agonist xanomeline maybe of benefit[8]
- tropsium/xanomeline may mitigate cholinergic adverse effects[8]
- tropsium/xanomeline (Cobenfy) FDA-approved ro schizophrenia Sept 2024
- novel trace amine-associated receptor 1 target may be of benefit[36]
- add-on treatment with pimavanserin (Nuplazid) may improve negative symptoms
- caution in treating hyperlipidemia
- increased serum cholesterol & serum triglycerides are associated with better cognitive function in patients with schizophrenia[23]
- non-pharmaceutical measures
- cognitive behavioral therapy useful for patients who refuse antipsychotics[21]
