Insights

Hypocalcemia affects nearly a quarter of young children with seizures. Exclusively breastfed infants under six months are particularly vulnerable, with hypovitaminosis-D being a common cause.

Area of Science:

  • Pediatrics
  • Nutritional Science
  • Neurology

Background:

  • Seizures in infants and young children can be a symptom of underlying metabolic disturbances.
  • Hypocalcemia (low calcium levels) is a recognized cause of seizures in pediatric populations.
  • Vitamin D deficiency (hypovitaminosis-D) is prevalent globally and can lead to hypocalcemia.

Purpose of the Study:

  • To determine the prevalence of hypocalcemia in developmentally normal children aged 1 month to 2 years presenting with seizures.
  • To investigate the role of hypovitaminosis-D as a contributing factor to hypocalcemia in this cohort.

Main Methods:

  • A one-year prospective study was conducted.
  • Seventy-eight developmentally normal children aged 1 month to 2 years with seizures were enrolled.
  • Prevalence of hypocalcemia, hypovitaminosis-D, and hypomagnesemia was assessed.

Main Results:

  • Overall, 18 out of 78 (23.1%) infants had hypocalcemia.
  • Hypovitaminosis-D was the cause in 15 infants (19.2%), while 3 (3.8%) had hypomagnesemia.
  • Infants exclusively breastfed under 6 months showed a significantly higher prevalence of hypocalcemia (41.67%) compared to older age groups (p=0.001).

Conclusions:

  • Hypocalcemia is a significant finding in young children presenting with seizures.
  • Hypovitaminosis-D is a primary driver of hypocalcemia in this pediatric group.
  • Exclusive breastfeeding in infants under six months necessitates monitoring for vitamin D sufficiency to prevent hypocalcemia and seizures.

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Epilepsy and Seizures: Overview01:24

Epilepsy and Seizures: Overview

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Antiepileptic Drugs: Calcium Channel Blockers01:17

Antiepileptic Drugs: Calcium Channel Blockers

Calcium channel blockers, a class of antiepileptic drugs, regulate the flow of calcium ions within neurons.
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...

Antiepileptic Drugs: Sodium Channel Blockers01:08

Antiepileptic Drugs: Sodium Channel Blockers

Antiepileptic drugs are specialized medications that prevent seizures in individuals diagnosed with epilepsy. These drugs primarily function by blocking the movement of sodium ions through channels in the neuronal membrane, inhibiting the repetitive firing of action potentials often associated with seizures.
Sodium channel blockers modulate ion channels, particularly voltage-gated sodium channels. They block only sodium ion movement.
Among the most commonly prescribed antiepileptic drugs are...

Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Synthesis and Functions of Calcitonin00:51

Synthesis and Functions of Calcitonin

Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...
