Objective: Vitamin D insufficiency/rickets is a metabolic bone disease that leads to insufficient mineralization of bone. Chronic neurological diseases, including cerebral palsy (CP), convulsive disorders, neural tube defects, myopathy, immobility, lack of sun exposure, inadequate nutrition, and antiepileptic drugs (AEDs) can cause vitamin D insufficiency and osteopenia in children.

Materials & methods: In this study, the authors searched the frequency and causative factors of vitamin D insufficiency in children with chronic neurological diseases such as

  • CP,
  • hypoxic-ischemic encephalopathy,
  • mental motor retardation,
  • epilepsy,
  • neurodegenerative and neuromuscular diseases,
  • meningitis-encephalitis sequelae,
  • neural tube defects,
  • paralysis, and
  • paresis.

This cross-sectional study included 108 children (forty-five (41.6%) females; sixty-three (58.4%) males), aged between one and 18 years with chronic neurological diseases, and a control group of thirty age-matched healthy children (16 (53.3%) females; 14 (46.7%) males.

Results: Vitamin D levels were significantly lower, and parathyroid hormone (PTH) levels were significantly higher in the patient group than in the control group (p<0.05). The patient group was divided into four subgroups: (i) Epilepsy (n=41; 38%), (ii) Neural tube defects (n=14; 13%), (iii) CP (n=21; 19%), and (iv) other diseases (neurodegenerative and neuromuscular diseases, meningitis sequelae, intracranial hemorrhage, psychomotor retardation, hypoxic-ischemic. Encephalopathy) (n=32; 30%) to identify any differences in the measured levels. In the patient group, eighty-three (76.9%) had vitamin D deficiency, and 17 (15.7%) had vitamin D insufficiency, while in the control group, twenty-one (70%) had vitamin D insufficiency. The use of AEDs had no significant effect on serum Ca, P, ALP, PTH, or vitamin D levels (p>0.05), and serum Ca levels were significantly higher in ambulant patients than in non-ambulant patients (p<0.05). Vitamin D levels were significantly higher in the non-ambulant than in the ambulant patients (p<0.05). No rickets was determined in the control group, while in the patient group, nine (8.3%) had level-1 rickets, six (5.6%) had level-2 rickets, and two (1.9%) had level-3 rickets.

Conclusion: Children with chronic neurological diseases have low serum vitamin D levels, and vitamin D prophylaxis is essential in this group.

VitaminDWiki – Overview Epileptic children and Vitamin D category contains

Fact: Anti-Epilepsy drugs lower vitamin D levels
Fact: Epilepsy 5X more likely if preterm
Fact: Preterm greatly decreased if add vitamin D and/or Omega-3
Fact: Vitamin D supplementation increases Vitamin D levels
Recommendation: Epileptics should take vitamin D to:
    Reduce the number of seizures (restore vitamin D then take maintenance dose of at least 5,000 IU daily)
   Avoid having health problems associated with low vitamin D, such as low bone density
1 study: Epileptics have low vitamin D levels before starting treatment

Epilepsy = 4,000 years of ignorance, superstition and stigma
   followed by 100 years of knowledge, superstition and stigma.
