Vitamin D in Neurological Diseases

Area of Science:

• Neuroscience
• Endocrinology
• Immunology

Background:

• Vitamin D plays a crucial role in nervous system function.
• Vitamin D deficiency is increasingly recognized as a potential risk factor for neurological disorders.
• Emerging research explores the therapeutic potential of vitamin D supplementation in neurodegenerative conditions.

Purpose of the Study:

• To provide a comprehensive overview of vitamin D's chemistry, metabolism, and mechanisms of action.
• To review the evidence linking low vitamin D levels to various neurological diseases.
• To summarize completed and ongoing clinical trials investigating vitamin D supplementation for neurological conditions.

Main Methods:

• Narrative review of existing scientific literature.
• Summary of vitamin D's effects on gene transcription and immune response.
• Discussion of epidemiological and clinical studies on vitamin D and neurological diseases.

Main Results:

• Low 25-hydroxyvitamin D concentrations are associated with an increased risk and progression of multiple sclerosis, Parkinson's disease, Alzheimer's disease, migraine, diabetic neuropathy, and amyotrophic lateral sclerosis.
• Vitamin D influences gene transcription and modulates immune responses, impacting neurological health.
• Numerous clinical trials are investigating the efficacy of vitamin D supplementation in managing these conditions.

Conclusions:

• Vitamin D status is a significant factor in neurological health.
• Further research and clinical trials are warranted to establish optimal vitamin D supplementation strategies for preventing and treating neurological diseases.
• Understanding vitamin D's multifaceted roles is crucial for advancing neuroprotection and disease management.
