Microcephaly and vulnerability of the brain in the etiology of cerebral palsy

Insights

A review of 100 children with cerebral palsy (CP) found that 37% had microcephaly. This suggests a potential link between small head size and the causes of CP.

Area of Science:

  • Pediatric Neurology
  • Developmental Neuroscience
  • Clinical Genetics

Background:

  • Cerebral palsy (CP) is a group of disorders affecting movement and posture, often stemming from developmental issues in the brain.
  • Microcephaly, characterized by a head circumference significantly smaller than average for age and sex, is a recognized indicator of abnormal brain development.
  • The etiological factors contributing to cerebral palsy are diverse and not fully understood, necessitating research into potential contributing conditions.

Purpose of the Study:

  • To investigate the prevalence of microcephaly in a cohort of children referred for evaluation of cerebral palsy.
  • To explore the potential significance of microcephaly as a finding in the etiology of cerebral palsy.

Main Methods:

  • Retrospective review of medical data for 100 children with a diagnosis or suspected diagnosis of cerebral palsy.
  • Assessment of head circumference measurements against age- and sex-specific normative data.
  • Definition of microcephaly as a head circumference of two or more standard deviations below the mean.

Main Results:

  • Out of 100 children evaluated for cerebral palsy, 37 were found to have microcephaly.
  • This represents a prevalence of 37% for microcephaly within this specific pediatric cohort.

Conclusions:

  • The high prevalence of microcephaly in children with cerebral palsy suggests a significant association.
  • Microcephaly may be an important indicator or contributing factor in the underlying causes of cerebral palsy, warranting further etiological investigation.

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...

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...
Neurulation01:30

Neurulation

Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...

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...
Increased Intracranial Pressure ll: Pathophysiology01:29

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
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...
