Movement disorders in bacterial meningitis
Abstract:
Movement disorders developed in five children, ages 6 to 21 months, during the course of bacterial meningitis caused by Hemophilus influenzae (one), Streptococcus pneumoniae (one), Neisseria meningitidis (one), or Mycobacterium tuberculosis (two). Athetosis, choreoathetosis, and hemiballismus occurred, ranging in duration from hours to months. Cranial computed tomography, performed in four cases, showed no lesion of the basal ganglia. The movements were of such abrupt onset and severity that in four cases they were initially misinterpreted as seizures, and anticonvulsant therapy was contemplated. It is important to recognize the potential development of movement disorders during the acute phase of bacterial meningitis to preclude the inappropriate administration of anticonvulsant medication.
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.
