Summary
Folate deficiency can cause serious neurological issues like neuropathy and spinal cord degeneration. Early diagnosis and folic acid treatment are crucial for recovery and preventing irreversible damage.
Area of Science:
- Neurology
- Nutritional Neuroscience
- Hematology
Background:
- Folate deficiency is linked to neurological disorders.
- Vitamin B12 deficiency also causes similar neurological symptoms.
- Distinguishing between the two is critical for effective treatment.
Purpose of the Study:
- To review the literature on folate-related neuropathy.
- To identify diagnostic criteria for folate deficiency neurological disorders.
- To investigate the biochemical basis of these neurological conditions.
Main Methods:
- Literature review of folate-related neuropathy.
- Analysis of 20 patients with neurological findings, low folate levels, and normal vitamin B12.
- Assessment of patient response to folic acid treatment.
Main Results:
- Ten patients had peripheral neuropathy, eight had subacute combined degeneration, and two had myelopathy.
- Neuropathy recurred in two patients when folate treatment lapsed.
- Mental changes and retardation also responded to folic acid therapy.
Conclusions:
- Low folate levels, even with normal vitamin B12, can cause significant neurological damage.
- The methionine synthetase reaction is implicated in both folate and vitamin B12 deficiency neurological consequences.
- Increased awareness and prompt diagnosis of folate deficiency are urged to prevent severe neurological outcomes.
