Summary
Acute psychosis following stroke is rare but linked to strategic infarcts. This study highlights two cases of stroke-induced psychosis, emphasizing the vascular origin and potential dysfunction in brain circuits.
Area of Science:
- Neuroscience
- Neurology
- Psychiatry
Background:
- Neuropsychiatric symptoms like hallucinations and delusions are uncommon stroke-related complications.
- These symptoms can manifest as acute psychosis of organic origin.
- Such cases often correlate with strategic infarcts in specific brain regions (caudate nucleus, striatum, thalamus).
Observation:
- Two cases of stroke-induced psychosis are presented.
- Case 1: A 67-year-old male experienced sudden delusions of persecution, with recovery in three months. MRI showed infarcts in the caudate nucleus.
- Case 2: A 49-year-old male presented with sudden delusions and gustative hallucinations, resolving in three months. MRI revealed a thalamic infarct.
Findings:
- Both cases suggest a vascular origin for psychosis, evidenced by sudden onset and recovery.
- Acute ischemic lesions were identified in strategic brain territories.
- The findings support the link between specific stroke locations and psychosis development.
Implications:
- The study discusses the potential vascular etiology of psychosis.
- It explores the underlying psychopathogenic mechanism involving prefrontal cortico-subcortical circuit dysfunction.
- Understanding these mechanisms can aid in diagnosing and managing stroke-related neuropsychiatric conditions.

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...
01:27Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within the...

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...
01:30Positive 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.

01:17Schizophrenia
Schizophrenia, a term introduced by Swiss psychiatrist Eugen Bleuler in 1911, describes a severe psychological disorder marked by profound disruptions in attention, thought processes, language, emotion, and interpersonal relationships. The core feature of schizophrenia is psychosis — a state characterized by a fundamental detachment from reality. This disconnection manifests through distorted logic, impaired perception, and atypical behavior, severely affecting the lives of those diagnosed.
01:20Personality Disorders: Schizotypal and Histrionic
Schizotypal personality disorder and histrionic personality disorder are two distinct psychological conditions classified under personality disorders, each characterized by unique behavioral patterns and social difficulties. Both disorders significantly affect interpersonal relationships and emotional well-being, leading to social isolation and frustration.
