Abstract

Insights

Multiple Sclerosis (MS) can manifest with psychotic symptoms, often presenting as primary psychotic or mood disorders. Treatment with corticosteroids may be effective, suggesting these episodes could be MS flares.

Area of Science:

  • Neurology
  • Psychiatry

Background:

  • Multiple Sclerosis (MS) is frequently linked to psychiatric symptoms, especially affective disorders.
  • The association between MS and psychotic disorders requires further clarification.

Purpose of the Study:

  • To systematically review and characterize cases of MS presenting with psychotic symptoms.
  • To establish the link between Multiple Sclerosis and psychotic disorders.

Main Methods:

  • A systematic review of the PubMed/MEDLINE database was conducted.
  • Identified cases of MS with psychotic symptoms were analyzed for demographics, clinical presentation, imaging, and treatment.

Main Results:

  • Ninety-one cases of MS with psychotic symptoms were identified, predominantly affecting females around age 34.
  • Most patients lacked prior MS or psychiatric history; diagnoses included psychotic disorders or mood disorders with psychotic features.
  • Sixty percent of cases with available imaging showed fronto-temporal lesions, often contrast-enhancing. Corticosteroid treatment was effective in the majority.

Conclusions:

  • Multiple Sclerosis can present with diverse psychotic symptoms.
  • The findings suggest that MS-associated psychotic episodes, characterized by enhancing lesions and steroid-responsiveness, may represent disease flares.

Psychosis 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...

Psychosis: 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...

Psychosis: 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...

Positive Symptoms Schizophrenia: Hallucinations and Delusions

Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

Psychological and Sociocultural Causes of Schizophrenia

Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
