    Study Notes

    Schizophrenia

    • Schizophrenia was originally coined by Eugen Bleuler to describe a type of psychotic disorder.

    Mortality Rate

    • Approximately 5% of individuals with schizophrenia die by suicide.

    Main Characteristics

    • The main characteristic of schizophrenia is a 'splitting of the associations between basic aspects of the same personality.'

    Eugen Bleuler's Concept

    • When Eugen Bleuler referred to a 'splitting of the associations between basic aspects of the same personality,' he was specifically referring to the disconnection between thinking, feeling, and perception.

    Heterogeneous Disorder

    • Schizophrenia is a heterogeneous disorder, meaning it has multiple causes and manifestations.

    Age and Gender

    • The highest peak onset of illness for males is in the early to mid-20s.
    • The onset of illness is more common in females in the late 20s.
    • Females tend to have better outcomes in general.

    Prevalence

    • The estimated lifetime prevalence of schizophrenia is approximately 0.5-1%.

    Symptoms of Schizophrenia

    • Positive symptoms involve an excess or distortion of normal behavior.
    • Negative symptoms involve a loss or decrease in normal behavior.
    • Cognitive symptoms involve difficulties with thinking, memory, and attention.

    Hallucinations

    • The most common type of hallucination in schizophrenia is auditory.
    • Auditory hallucinations sometimes involve a voice commenting on the person's actions.
    • Functional neuroimaging studies have found that hallucinations in schizophrenia involve abnormal activity in the brain's auditory cortex.
    • Hallucinations in schizophrenia are characterized as false sensory perceptions that occur in the absence of an external stimulus.

    Delusions

    • Delusions are defined as false, firm beliefs that are not based on reality.
    • Delusions are distinguished from other types of thoughts by their degree of conviction and imperviousness to evidence.
    • Delusions can be bizarre or non-bizarre, with bizarre delusions being more characteristic of schizophrenia.
    • Examples of delusions include persecutory delusions, referential delusions, and grandiose delusions.

    Negative Symptoms

    • Negative symptoms of schizophrenia include alogia (poverty of speech), avolition (lack of motivation), anhedonia (lack of pleasure), and asociality (lack of interest in social activities).

    Disorganized Symptoms

    • Disorganized symptoms of schizophrenia involve a variety of erratic behaviors that affect speech motor behavior and emotional reactions.
    • Examples of disorganized symptoms include derailment (thinking that involves going off-topic), tangentiality (thinking that involves going off-topic and never returning to the original point), and neologisms (creation of new words that have meaning only to the individual).

    Cognitive Deficits

    • Individuals with schizophrenia often have cognitive deficits, particularly in attention, memory, and executive function.
    • Approximately 70% of individuals with schizophrenia perform in the impaired range on cognitive tasks.
    • A monozygotic twin study involving schizophrenia-discordant twin pairs revealed that cognitive performance in individuals with schizophrenia is characterized by subtle deficits that predate the onset of illness.
