Catatonic Type Schizophrenia Subchronic State with Acute Exacerbation

The term "catatonic type schizophrenia subchronic state with acute exacerbation" refers to a specific subtype of schizophrenia that was previously recognized in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). According to the search results, this subtype is characterized by a subchronic course of illness, meaning it lasts for more than 3 months but less than 6 months, with acute exacerbations.

Key Features

• Subchronic course of illness: The condition lasts for more than 3 months but less than 6 months.
• Acute exacerbation: There are periods of worsening symptoms, which can include psychotic symptoms such as delusions and hallucinations.
• Catatonic symptoms: Abnormalities in motor functioning, including catatonia, may be present.

Relevance to Modern Diagnosis

It's worth noting that the American Psychiatric Association (APA) combined all subtypes of schizophrenia under a general category of schizophrenia in 2013. Therefore, this specific subtype is no longer recognized as a distinct diagnosis in modern psychiatric classification systems.

However, the symptoms and characteristics associated with catatonic type schizophrenia subchronic state with acute exacerbation may still be relevant for clinicians and researchers working with individuals who exhibit similar symptom profiles.

Catatonic Type Schizophrenia Subchronic State with Acute Exacerbation

The subchronic state with acute exacerbation of catatonic type schizophrenia is characterized by the reemergence of prominent psychotic symptoms in a person who has been in the residual phase of the disorder (8). This condition is marked by a sudden and significant worsening of symptoms, which can include:

• Catatonic Symptoms: People with this subtype exhibit unusual styles and levels of physical movement. For example, such a person may move their body erratically or not at all (12).
• Positive Symptoms: These can include delusions or delusional ideation, hallucinations, disturbance of association, catatonic symptoms, agitations, and other similar manifestations (4, 9).
• Psychotic Symptoms: Signs of psychosis, such as delusions and hallucinations, may also be present (2).

It's essential to note that the American Psychiatric Association removed "catatonic schizophrenia" from its list of official diagnoses when updating to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders in 2013. The World Health Organization (WHO) also removed this subtype from the International Classification of Diseases when updating to the 11th edition (ICD-11) in 2019.

Diagnostic Tests for Obsolete Catatonic Type Schizophrenia Subchronic State with Acute Exacerbation

The diagnostic tests for catatonic type schizophrenia, including the subchronic state with acute exacerbation, have evolved over time. However, some of these tests are still relevant today.

• Blood, urine and cerebrospinal fluid (spinal tap) tests: These tests were used to look for chemical changes in bodily fluids, as well as heavy metal poisoning, infections, and other conditions that may be associated with catatonic type schizophrenia. [1]
• Psychiatric evaluation: A thorough psychiatric evaluation is essential to diagnose catatonic type schizophrenia, including the subchronic state with acute exacerbation. This involves assessing symptoms such as delusions, hallucinations, disorganized thinking, and negative symptoms. [3][5]
• ICD-9-CM codes: In the past, ICD-9-CM codes were used to classify catatonic type schizophrenia, including the subchronic state with acute exacerbation. The relevant codes include 295.24 for Schizophrenia, Catatonic Type, Subchronic with Acute Exacerbation and 295.25 for Schizophrenia, Catatonic Type, Chronic with Acute Exacerbation. [4][5]
• Catatonia rating scales: Catatonia rating scales, such as the Bush-Francis Catatonia Rating Scale (BFCRS), can be used to assess the severity of catatonic symptoms in individuals with schizophrenia. [7]

It's worth noting that the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) previously classified schizophrenia into five subtypes, including disorganized schizophrenia, paranoid schizophrenia, residual schizophrenia, undifferentiated schizophrenia, and catatonic schizophrenia. However, these subtypes have been combined under the general category of schizophrenia in the DSM-5. [14]

Treatment Options for Obsolete Catatonic Type Schizophrenia

Catatonic type schizophrenia, a rare and severe form of the condition, can be challenging to treat. However, various drug treatments have been effective in managing its symptoms.

• Benzodiazepines: These anti-anxiety medications are often the first line of treatment for catatonia, including the catatonic type of schizophrenia. They can help alleviate symptoms such as agitation and aggression [3].
• Electroconvulsive Therapy (ECT): ECT has been shown to be effective in treating catatonia, including cases associated with schizophrenia. It is particularly useful when benzodiazepines are ineffective or contraindicated [5][6].
• Antipsychotics: While antipsychotics should be used with caution in the absence of a psychotic disorder, they may be necessary to treat the underlying schizophrenia. However, their use should be carefully considered and monitored due to potential side effects [9].

Important Considerations

It is essential to note that catatonic type schizophrenia carries a poorer prognosis than other forms of the condition. Early detection and treatment are crucial for improving outcomes.

• Early Detection: Prompt diagnosis and treatment can significantly improve outcomes for individuals with catatonic type schizophrenia.
• Combination Therapy: In some cases, a combination of ECT and clozapine may be effective in treating chronic catatonia associated with schizophrenia [5].

The differential diagnosis for an obsolete catatonic type schizophrenia subchronic state with acute exacerbation involves considering various conditions that may present with similar symptoms.

Conditions to Consider:

• Catatonia: A neuropsychiatric disorder characterized by immobility, mutism, and rigidity. Catatonia can be a feature of schizophrenia, but it can also occur independently or as a result of other medical conditions.
• Acute Delirium: A state of confusion and altered consciousness that can be caused by various factors such as medication overdose, infection, or metabolic disorders.
• Viral Encephalitis: An inflammation of the brain caused by viral infections, which can lead to symptoms like catatonia, mutism, and rigidity.
• Dementia Praecox (Schizophrenia): A chronic mental disorder characterized by delusions, hallucinations, and disorganized thinking. Catatonic schizophrenia is a subtype that was previously recognized but is no longer used in modern diagnostic criteria.

Key Symptoms to Consider:

• Immobility
• Mutism
• Rigidity
• Altered consciousness
• Confusion
• Delirium

Diagnostic Approach:

When diagnosing an obsolete catatonic type schizophrenia subchronic state with acute exacerbation, it is essential to consider the following steps:

1. Medical Evaluation: Rule out underlying medical conditions that may be causing the symptoms.
2. Psychiatric Assessment: Evaluate the patient's mental status, including their cognitive function, mood, and behavior.
3. Neuropsychological Testing: Perform neuropsychological tests to assess cognitive function and identify any deficits.
4. Imaging Studies: Conduct imaging studies such as CT or MRI scans to rule out structural brain abnormalities.
