Cushing Syndrome II: Pathophysiology01:19

Cushing Syndrome II: Pathophysiology

Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...

Parkinson's Disease: Overview

Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is to...
Cushing Syndrome I: Introduction01:26

Cushing Syndrome I: Introduction

Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
Neural Regulation01:37

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
Encephalitis l: Introduction01:19

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
Alterations in Muscle Tone ll01:12

Alterations in Muscle Tone ll

Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...

Summary

Paraneoplastic neurological syndromes (PNS) are neurological disorders linked to cancer, often appearing before cancer diagnosis. Advances in understanding auto-antibodies are improving diagnosis and treatment strategies for these complex conditions.

Area of Science:

  • Neurology
  • Immunology
  • Oncology

Background:

  • Paraneoplastic neurological syndromes (PNS) are rare disorders where neurological symptoms precede or accompany an occult malignancy.
  • Classical PNS presentations are well-defined, but recent discoveries have expanded the spectrum of these syndromes.
  • The evolution of limbic encephalitis diagnosis highlights recent advances driven by new auto-antibody discoveries.

Purpose of the Study:

  • To review the specificities and recent advancements in the treatment of paraneoplastic neurological syndromes (PNS).
  • To highlight the evolving understanding of PNS, particularly concerning auto-antibodies and their diagnostic and therapeutic implications.

Main Methods:

  • Review of current literature on paraneoplastic neurological syndromes.
  • Analysis of recent findings regarding auto-antibodies associated with PNS.
  • Discussion of diagnostic and therapeutic strategies based on immunological markers.

Main Results:

  • PNS are characterized by neurological deficits often preceding clinically evident cancer.
  • New auto-antibodies have significantly advanced the understanding and diagnosis of syndromes like limbic encephalitis.
  • Cancer diagnosis and treatment remain paramount, but neurological symptom management is guided by immunological findings.

Conclusions:

  • There is a growing recognition of a wider range of PNS and associated paraneoplastic antibodies.
  • Immunological studies increasingly support the pathogenic role of specific auto-antibodies in PNS.
  • Some identified antibodies serve as crucial biological markers for disease diagnosis and management.
