Movement disorders in bacterial meningitis

Insights

Bacterial meningitis can cause movement disorders like athetosis and choreoathetosis in young children. Early recognition is crucial to avoid misdiagnosis as seizures and inappropriate anticonvulsant treatment.

Area of Science:

  • Neurology
  • Pediatrics
  • Infectious Diseases

Background:

  • Bacterial meningitis is a serious infection affecting the central nervous system in children.
  • Movement disorders are not commonly associated with the acute phase of bacterial meningitis.

Observation:

  • Five children (6-21 months) developed movement disorders during bacterial meningitis.
  • Observed movement disorders included athetosis, choreoathetosis, and hemiballismus.
  • Symptoms ranged from hours to months, with abrupt onset and severity.

Findings:

  • Cranial CT scans in four cases showed no basal ganglia lesions.
  • Movement disorders were initially mistaken for seizures in four patients.
  • Causative agents included Hemophilus influenzae, Streptococcus pneumoniae, Neisseria meningitidis, and Mycobacterium tuberculosis.

Implications:

  • Highlights the importance of recognizing movement disorders as a potential complication of bacterial meningitis.
  • Prevents misdiagnosis and inappropriate anticonvulsant therapy in affected children.
  • Informs clinical practice for pediatric infectious disease and neurology specialists.

Bacterial Meningitis

Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
Botulism01:22

Botulism

Botulism is a life-threatening neuroparalytic condition caused by botulinum neurotoxin, which is produced by the bacterium Clostridium botulinum, a Gram-positive, spore-forming, obligate anaerobe.In adults, the toxin enters the body in different ways: in foodborne botulism, the preformed toxin is absorbed in the intestine. In wound botulism, spores grow in injured tissue and release the toxin into the blood. Infant botulism differs mechanistically from adult forms. In infants, botulism commonly...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
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...
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...
