Insights

Subacute sclerosing panencephalitis (SSPE) is a rare, fatal measles complication. This study details two adult female cases with atypical presentations, including one during pregnancy, highlighting disease progression and neurodegenerative links.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Pathology

Background:

  • Subacute sclerosing panencephalitis (SSPE) is a rare, progressive neurological complication of measles infection, typically affecting children and adolescents.
  • Adult-onset SSPE is exceptionally uncommon, with limited documented cases in medical literature.

Observation:

  • Presents two new cases of adult women with SSPE, one experiencing the disease during pregnancy.
  • Both cases exhibited highly atypical clinical features, disease presentation, and progression.
  • Pregnancy appeared to negatively influence the disease course, consistent with previous reports.

Findings:

  • The patients displayed a prolonged biphasic clinical course, including extended periods of remission lasting several years.
  • Neuropathological examination revealed inflammatory processes alongside neurodegenerative features, such as neurofibrillary tangle formation.
  • These histological findings suggest a potential link between SSPE and other tauopathies.

Implications:

  • Highlights the possibility of atypical SSPE presentations in adults, necessitating broader diagnostic considerations.
  • Underscores the adverse impact of pregnancy on SSPE progression.
  • Suggests a potential shared pathogenic mechanism between SSPE and tauopathies, warranting further investigation into neurodegenerative pathways.

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

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...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
Bacterial Meningitis II: Pathophysiology01:26

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
Arboviral Encephalitis01:25

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
