Dementia Praecox is a designation that is no longer being used and is now replaced by schizophrenia. Schizophrenia is a serious mental illness that may impact a person’s thoughts, behavior, speech, and perception of reality. It generally develops between the late teenage years and the mid-30s.
This article provides a comprehensive overview of dementia praecox (schizophrenia), including its definition, causes, symptoms, and treatment.
Definition of dementia praecox (schizophrenia)
Dementia praecox was first popularized as a diagnostic concept by Emil Kraepelin, a German psychiatrist, in the late nineteenth century. During this time, dementia praecox and manic depressive psychosis were considered the two major psychotic disorders.
Dementia praecox (schizophrenia) describes a group of mental disorders with similar symptoms, including hallucinations, delusions, and disorganized thinking. The degeneration theory suggests that dementia praecox is a form of mental deterioration that involves an irreversible decline in mental functioning and a poor prognosis. On the other hand, manic depressive psychosis was classified as an episodic mood disorder that did not lead to impaired cognitive functioning.
While dementia praecox may not be in active use, Kraepelin’s concept of dementia praecox was interchangeable with schizophrenia. In 1918, the designation “schizophrenia” was suggested as an alternate term for dementia praecox. For modern researchers and mental health professionals, schizophrenia is the accepted term for the disorder once known as dementia praecox in psychiatric literature and science history publications.
The disease concept of psychiatric conditions like schizophrenia has evolved considerably since the historical concept of dementia praecox was first introduced, reflecting changes in our understanding of these disease processes. Since the nineteenth century, advancements in behavioral genetics have provided insights into the heritability and genetic risk factors linked to various psychiatric disorders, influencing the field of biological psychiatry and shaping contemporary diagnostic systems.
This article uses the modern designation of schizophrenia and current research about this mental illness.
What is schizophrenia?
According to the American Psychological Association, “schizophrenia is a serious mental illness characterized by incoherent or illogical thoughts, bizarre behavior and speech, and delusions or hallucinations, such as hearing voices. The age of onset is typically between the late teens and mid-30s.”
Causes of schizophrenia
The causes of schizophrenia are unknown. However, psychiatric and behavioral genetics research suggests that “a combination of physical, genetic, psychological, and environmental factors can make a person more likely to develop the condition.” This aligns with the idea that other psychiatric disorders, including manic depressive insanity, now known as bipolar disorder, may be linked to various factors.
Some individuals might be prone to schizophrenia due to genetics; others might experience a stressful or emotional life event that triggers the onset of this mental illness. Researchers currently don’t know why some individuals develop schizophrenia symptoms.
Here are some potential risk factors that may increase the likelihood of schizophrenia symptoms:
Genetics: Evidence has not revealed a specific gene responsible for schizophrenia, but it appears to run in families
Brain development: There may be subtle differences in the brain structure of individuals who experience schizophrenia symptoms
Neurotransmitters: Those who experience schizophrenia symptoms might have different amounts of certain neurotransmitters in their brains
Pregnancy and birth complications: Pregnancy complications, such as low birth weight, premature labor, and lack of oxygen during birth, are thought to affect brain development, which may increase the risk of the baby developing schizophrenia later in life
Here are some potential life events that may trigger schizophrenia to develop in individuals who are at risk:
Stress: The primary psychological triggers for schizophrenia appear to be stressful life events like divorce, losing a job, losing a home, grief, the end of a relationship, or physical, sexual, or emotional abuse*
Substance use: Some research suggests that using drugs such as cannabis, cocaine, LSD, or amphetamines may increase the risk of developing schizophrenia in individuals predisposed to the condition
These triggers or experiences do not cause schizophrenia. Instead, research suggests that they may trigger its development in individuals who are vulnerable to it.
Symptoms of schizophrenia as a mental illness
According to the American Psychological Association, active schizophrenia can be characterized by episodes in which the person cannot distinguish reality from unreal experiences. The severity, frequency, and duration of symptoms can vary between individuals. For example, a person might start experiencing symptoms during their teenage years. However, as the person reaches early adulthood, the full spectrum of symptoms may become evident.
The symptoms of schizophrenia fall into three major categories:
Positive symptoms: Hallucinations, including visual and auditory hallucinations, paranoia, and exaggerated or distorted behaviors, beliefs, and perceptions
Negative symptoms: A decrease in the ability to express emotion, speak, initiate plans, or partake in enjoyable activities
Disorganized symptoms: Confused or disordered thinking and speech, bizarre behavior, abnormal movements, and challenges with logical thought processes
Individuals experiencing schizophrenia symptoms might also struggle with attention, memory, and concentration.
Treatment of schizophrenia
There is no known cure for schizophrenia at the time of this writing. However, there are treatment options that may help manage symptoms and improve the quality of life for many individuals.
Practitioners of clinical psychiatry might recommend a combination of medication and therapy as a common approach to help manage schizophrenia symptoms.
Medication: Antipsychotic medications may help reduce or control positive symptoms for some individuals. A psychiatrist may need to work with the patient to try different medications and doses to find the most effective option.
Therapy: Individual talk therapy, family therapy, cognitive-behavioral therapy, and social skills training may help individuals who experience schizophrenia learn coping strategies and improve social functioning.
With treatment, many individuals who experience schizophrenia symptoms can successfully pursue their goals, maintain healthy relationships, and keep stable jobs.
Online therapy for schizophrenia and other mental disorders
Therapy may offer numerous benefits that can improve the overall quality of life for individuals diagnosed with schizophrenia. Individuals may learn coping skills, improve communication skills, and gain insight into the symptoms they experience. It may also be helpful for individuals who experience other mental health problems alongside schizophrenia, such as personality disorders and major depression. A fundamental feature of therapy is the personalization of care that takes into account the complex nature of schizophrenia.
Online therapy offers a beneficial option for individuals who would like to partake in treatment from home. It’s often more affordable and provides an opportunity to connect with a broader range of professionals than local options. Like in-person treatment, remote therapy can provide individuals with emotional support and validation, creating a safe and supportive environment for discussing experiences and emotions.
For individuals diagnosed with schizophrenia, reducing symptoms is often one of the primary goals of therapy. Multiple studies have demonstrated its effectiveness in reducing positive and negative symptoms. Research shows that online therapy offers the same benefits as traditional treatment.

Is dementia praecox the same as schizophrenia?
"Dementia praecox" is an older term that was historically used to describe what is now known as the mental disorder schizophrenia. The term was coined by German psychiatrist Emil Kraepelin in the late 19th and early 20th centuries. Kraepelin used the term to refer to a group of disorders characterized by early-onset psychosis, cognitive decline, and a chronic course.
In the early twentieth century, psychiatrist Eugen Bleuler introduced the term "schizophrenia" to replace "dementia praecox." Bleuler's intent was to emphasize the disorder's primary symptoms, such as disruptions in thought processes, perception, and emotions, rather than the idea of premature dementia. "Schizophrenia" translates to "split mind" in Greek, reflecting the fragmentation of mental processes seen in the disorder.
"Dementia praecox" is an outdated term that was historically used to describe what is now recognized as schizophrenia. It may be important to note that the term "dementia praecox" is no longer used in contemporary psychiatric practice, and the understanding of schizophrenia has evolved over time.
Schizophrenia is a complex mental health disorder that requires a psychiatric diagnosis and is characterized by a range of symptoms that affect thinking, emotions, and behavior. The symptoms of schizophrenia include:
- Psychosis: According to the American Psychiatric Association, individuals may have hallucinations or delusions, which may manifest alongside depression as manic depressive psychosis. Individuals may have a hard time believing they are hallucinating or deluded.
- Thought Disorders: Disorganized thinking, which may manifest as incoherent speech, difficulty organizing thoughts, or tangential or illogical associations.
- Blunted Affect: Reduced emotional expressiveness, including facial expressions, gestures, and vocal tone.
- Alogia: Limited speech output, including poverty of speech (reduced quantity) and poverty of content (lack of meaningful information).
- Anhedonia: Reduced ability to experience pleasure or interest in activities.
- Social Withdrawal: Difficulty establishing and maintaining relationships, and a preference for isolation.
- Impaired Executive Function: Difficulties with planning, organizing, initiating tasks, and maintaining attention.
- Working Memory Impairment: Difficulty holding and manipulating information in the mind for short periods.
- Attentional Impairment: Challenges in sustaining attention on tasks.
What is the psychology of dementia praecox?
The psychology of the mental disease dementia praecox or schizophrenia, as it is understood today through clinical research, involves an intricate interplay of genetic, biological, environmental, and neurodevelopmental factors. Here are some key aspects of the psychology of schizophrenia:
- Brain Structure and Function: Abnormalities in brain structure and function, particularly in regions related to cognitive processes, emotions, and perception, are observed in individuals with schizophrenia.
- Neurotransmitter Imbalances: Dysregulation of neurotransmitters, such as dopamine, glutamate, and serotonin, is implicated in the pathophysiology of schizophrenia.
- Genetic Factors: There is a genetic component to schizophrenia, as the disorder tends to run in families. Individuals with a first-degree relative (parent or sibling) with schizophrenia have a higher risk of developing the condition.
- Developmental Factors: Factors during prenatal and perinatal development or pregnancy complications, such as maternal stress, malnutrition, or exposure to certain toxins, may contribute to an increased risk of schizophrenia.
- Stress and Trauma: Exposure to significant stressors or psychological trauma during childhood or adulthood may contribute to the onset or exacerbation of symptoms.
- Family Dynamics: Although not a direct cause, family interactions, and dynamics may influence the course of the illness and the effectiveness of treatment.
- Cognitive Factors: Cognitive deficits are common in schizophrenia and can affect various domains, including attention, memory, executive function, and social cognition.
- Psychological Symptoms: Positive symptoms (hallucinations, delusions, disorganized thinking), negative symptoms (blunted affect, anhedonia, social withdrawal), and cognitive symptoms (impaired executive function, working memory deficits) characterize the psychological manifestations of schizophrenia.
- Psychosocial Functioning: Schizophrenia can significantly impact psychosocial functioning, including the ability to work, maintain relationships, and engage in daily activities. Social isolation and stigmatization can further contribute to the psychological challenges faced by individuals with schizophrenia.
What illness does the Latin term dementia praecox relate to?
The Latin term "dementia praecox" translates to "premature dementia." It was historically used by German psychiatrist Emil Kraepelin in the late 19th and early 20th centuries to describe a group of psychiatric disorders and mental diseases characterized by early-onset psychosis, cognitive decline, and a chronic course. These disorders were all called dementia praecox, however, the term was primarily associated with what is now recognized as schizophrenia.
What is the modern name for dementia praecox?
The modern name for what was historically referred to as "dementia praecox" is schizophrenia. According to the World Health Organization, 24 million people worldwide may be living with schizophrenia. Schizophrenia may have overlapping symptoms with bipolar disorder, formerly called manic depressive illness, however, they are two distinct conditions in the Diagnostic and Statistical Manual Fifth Edition.
What age does dementia praecox occur?
The onset of dementia praecox, now called schizophrenia, typically occurs in late adolescence or early adulthood, but it can develop at any age. The most common age of onset for schizophrenia is in the late teens to early 30s. However, it may be important to note that the disorder can occur earlier or later in life. Early-onset schizophrenia, which manifests in childhood or early adolescence, is less common but does occur. Late-onset schizophrenia, occurring after the age of 40 or 50, is also possible, though it is relatively rare.
The "4 A's" is a historical mnemonic used to describe some of the characteristic symptoms of schizophrenia. These symptoms, which were identified by psychiatrist Eugen Bleuler, do not encompass all aspects of the disorder, but they highlight certain features commonly observed in individuals with schizophrenia. The "4 A's" include:
Associations (Loosening of Associations):
Refers to disorganized thinking and speech patterns where ideas are not logically connected. Individuals with schizophrenia may have difficulty organizing their thoughts, and their speech may be incoherent or lack coherence.
Affect (Blunted or Flat Affect):
Describes disturbances in emotional expression. People with schizophrenia may exhibit a blunted or flat affect which may be common in individuals with schizoid personality disorders, meaning they show reduced or minimal emotional expressiveness. This can involve a limited range of facial expressions, gestures, and vocal tones.
Ambivalence:
Ambivalence refers to the coexistence of opposing emotions or attitudes toward a particular idea, object, or person. In schizophrenia, individuals may struggle with conflicting feelings and find it challenging to make decisions or express clear preferences.
Autism (Autistic Thinking):
In the context of schizophrenia, "autism" refers to a disturbance in social interaction and communication. People with schizophrenia may withdraw from social interactions, have difficulty relating to others, and may appear absorbed in their own thoughts or inner experiences.
It may be important to note that while these "4 A's" highlight certain symptoms, schizophrenia is a complex disorder with a broad range of symptoms that extend beyond these mnemonic categories.
Why is it called dementia praecox?
"Dementia praecox" is a Latin term that translates to "premature dementia." The term was coined by German psychiatrist Emil Kraepelin in the late 19th and early 20th centuries. Kraepelin used this term to describe a group of psychiatric disorders characterized by early-onset psychosis, cognitive decline, and a chronic course.
The choice of the term reflects Kraepelin's observation that individuals with these disorders appeared to experience a progressive deterioration in cognitive and emotional functioning at a young age. The use of the term "dementia" in this context reflects the idea that these disorders involve a decline in mental abilities, similar to what is observed in dementia but occurring at a younger age than typical cases of dementia.
"Folie à deux," which translates to "madness for two" in French, refers to a psychiatric phenomenon in which a delusional belief is common among two people who are in close emotional or social relationships. It's also known as shared psychotic disorder.
In a folie à deux scenario, one person (the primary or inducer) has a delusional belief, and the second person (the secondary or recipient) comes to adopt and have that belief. The mutual delusional content is usually centered around a specific theme, and the individuals involved may reinforce and elaborate on the delusion together.
This phenomenon typically occurs within close relationships, such as between family, spouses, or close friends. The person with the primary psychotic disorder often influences the person with the secondary role, who may not have had any psychiatric illness prior to the mutual delusional experience.
"Pseudodementia" is a term that was historically used to describe a condition in which individuals exhibit fundamental symptoms that resemble those of dementia but are not caused by a neurodegenerative process and do not meet diagnostic criteria. Rather, the cognitive impairment seen in pseudodementia is thought to be related to a psychiatric or psychological disorder.
One common psychological disorder associated with pseudodementia is depression, particularly a severe form of depression known as major depressive disorder. In pseudodementia due to depression, individuals may present with cognitive symptoms such as memory loss, difficulty concentrating, and impaired executive function, which can mimic the cognitive deficits seen in dementia.
