Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders01:27

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

2.3K
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...

Psychosis and Antipsychotic Drugs: Overview

1.1K
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...

Psychosis: Goals of Pharmacotherapy

653
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.

Psychosurgery01:30

Psychosurgery

2.2K
Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Schizophrenia01:17

Schizophrenia

1.5K
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...

Panic Disorder01:27

Panic Disorder

1.0K
Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...

Summary
This summary is machine-generated.

Psychotic symptoms are rarely linked to midbrain lesions. This case suggests a midbrain lesion may contribute to psychosis in susceptible individuals, even when stable.

Area of Science:

  • Neuroscience
  • Neurology
  • Psychiatry

Background:

  • Psychotic symptoms are infrequently associated with central nervous system (CNS) lesions confined to the midbrain.
  • Hereditary and environmental factors can increase psychiatric illness risk.

Observation:

  • A 15-year-old boy with a history of midbrain pilocytic astrocytoma presented with non-epileptic seizures, hyper-religiosity, and psychosis.
  • The patient's midbrain lesion remained radiographically stable, while his psychiatric condition worsened.

Findings:

  • This case highlights the potential for midbrain lesions to induce psychotic symptoms in vulnerable individuals.
  • The patient's presentation suggests psychosis secondary to the midbrain lesion.

Implications:

  • This case expands understanding of the neurobiological underpinnings of psychosis.
  • Further research into the relationship between midbrain pathology and psychiatric manifestations is warranted.
