Insights

Persistent neurological and cognitive impairments after cerebral malaria are linked to factors like seizures and coma. Identifying these risk factors is crucial for developing future prevention strategies.

Area of Science:

  • Neurology
  • Pediatrics
  • Infectious Diseases

Background:

  • Cerebral malaria frequently leads to lasting neurological and cognitive deficits.
  • While risk factors for severe outcomes are known, those for persistent impairments require further investigation.

Purpose of the Study:

  • To identify risk factors associated with persistent neurological and cognitive impairments following cerebral malaria in children.

Main Methods:

  • A retrospective study analyzed hospital records of 143 children (aged 6-9 years) with cerebral malaria.
  • Assessments for motor, speech, language, and cognitive impairments were conducted at least 20 months post-discharge.

Main Results:

  • 23.8% of children exhibited impairments, including motor (9.8%), speech/language (11.2%), and cognitive (14.0%).
  • Independent risk factors for persistent impairments included previous seizures, deep coma, focal neurological signs, and discharge neurological deficits.
  • Specific impairments were associated with factors like multiple seizures, young age, malnutrition, intracranial hypertension, and hypoglycemia.

Conclusions:

  • Key risk factors for persistent impairments are multiple seizures, deep/prolonged coma, hypoglycemia, and intracranial hypertension.
  • Distinct risk factors for specific functional impairments suggest varied mechanisms of neuronal damage.
  • These findings can inform the development of preventive strategies for post-cerebral malaria impairments.

Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Malaria01:29

Malaria

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
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: 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...
Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
Hepatic Encephalopathy01:29

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
