Summary
Long-term remissions in schizophrenia, termed "dyskinetic," are characterized by motor disturbances and catatonic symptoms. These remissions, showing good social adjustment, present in hyperkinetic and hypokinetic forms.
Area of Science:
- Psychiatry
- Neurology
Context:
- Investigating long-term remissions in schizophrenia with catatonic features.
- Focusing on patients with shift-like schizophrenia and catatonic disorders.
Purpose:
- To characterize "dyskinetic" remissions in schizophrenia.
- To identify subtypes and psychopathological structures of dyskinetic remissions.
- To hypothesize the role of catatonic symptoms in these defects.
Summary:
- The study analyzed 32 patients with 5-33 year remissions after shift-like schizophrenia with catatonic disorders, noting good social/professional adjustment.
- These remissions, termed "dyskinetic," feature motor disturbances and microcatatonic symptoms (stupor, excitement), with stereotype urges, psychomotor passivity, and catatonic reactions.
- Two types, hyperkinetic and hypokinetic dyskinetic remission, were identified, defined by specific psychopathological structures: "monotonous activity and rigidity of affect" for hyperkinetic, and "irritable asthenia" for hypokinetic.
Impact:
- Provides a novel classification of schizophrenia remission subtypes.
- Enhances understanding of the relationship between catatonia and long-term outcomes in schizophrenia.
- Offers insights into the psychopathological underpinnings of distinct remission patterns.

01:26Psychosis: Goals of Pharmacotherapy
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation. For...
01:28Psychosis and Antipsychotic Drugs: Overview
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic symptoms in all...
01:28Drug Therapy
The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

01:30Positive Symptoms of Schizophrenia: Hallucinations and Delusions
Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.

01:25Long-term Potentiation
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.
