Pyridoxine dependency? (2023)

How does pyridoxine deficiency cause seizures?

Vitamin B6 deficiency and seizures

A deficiency of PLP leads to decreased GABA concentration in the brain, thereby increasing the risk for seizures (18). Seizures caused by vitamin B6 deficiency was first described in 1954 by Hunt et al (1).

What is pyridoxine-dependent epilepsy in adults?

Pyridoxine-dependent epilepsy – ALDH7A1 (PDE-ALDH7A1) is characterized by seizures not well controlled with anti-seizure medication that are responsive clinically and electrographically to large daily supplements of pyridoxine (vitamin B₆).

What is the result of pyridoxine deficiency?

Vitamin B6 deficiency may present with seizures, mental status changes, normocytic anemia, a nonspecific pruritic rash, cheilitis, glossitis, and depression.

Vitamin B6 deficiency is associated with microcytic anemia, electroencephalographic abnormalities, dermatitis with cheilosis (scaling on the lips and cracks at the corners of the mouth) and glossitis (swollen tongue), depression and confusion, and weakened immune function [1,2].

What causes pyridoxine dependency?

B6 dependency syndromes are a group of metabolic disorders that respond to large doses of vitamin B6. Although rare, pyridoxine-dependent seizure (PDS) is a recognized cause of intractable seizures in neonates, psychomotor developmental delay, and, sometimes, death in untreated patients.

When epilepsy is diagnosed in older adults, it's sometimes from another neurological issue, like a stroke or a brain tumor. Other causes can be related to genetic abnormalities, prior brain infection, prenatal injuries or developmental disorders. But in about half of people with epilepsy, there's no apparent cause.

Can low B6 cause anxiety?

Mood Changes

Shortfalls of B6 may affect your mood, sometimes contributing to depression, anxiety, irritability and increased feelings of pain ( 16 ). That's because B6 is involved in the making of several neurotransmitters, such as serotonin and gamma-aminobutyric acid (GABA).

Does pyridoxine increase dopamine?

Pyridoxine has both dopamine-enhancing and dopamine-blocking properties: on the one hand pyridoxine (like dopamine) depresses the release of prolactin from the pituitary gland; on the other hand, in oral doses of 10–20 mg it rapidly reverses the therapeutic effect of dopamine [14].

Who is most likely to inherit epilepsy?

First-degree relatives of people with inherited epilepsy have a two- to four-fold increased risk for epilepsy. Although there is some increased risk, it is important to remember that the overall risk of epilepsy in other family members is still low.

Can you become immune to epilepsy medication?

Some people with epilepsy find that over time they have to take larger and larger doses of their seizure medicine to achieve the same result. This effect is known as tolerance. Studies in both humans and animals have shown that tolerance is not much of a problem for most of the standard antiepileptic drugs.

Do all epileptics get dementia?

In recent years, researchers have uncovered a link between Alzheimer's disease and epilepsy. People with epilepsy develop Alzheimer's disease at a rate 6 times higher than the non-epileptic population, and seizures can damage the memory centers of the brain and contribute to dementia.

How old do epileptics live?

On average, people with epilepsy live 10-12 years fewer than those who do not have the condition. Excess mortality is particularly pronounced among people with epilepsy and mental disorders. This is shown by research from Aarhus University.

Does epilepsy come from Mom or Dad?

Having an affected mother was associated with a 1.45‐fold (95% CI: 1.30–1.63) higher risk of epilepsy in the offspring, compared to having an affected father.

Many people are not aware that vitamin B6 can cause peripheral neuropathy, which results in tingling, burning or numbness usually in the hands and feet. Taking vitamin B6 even at low doses can cause peripheral neuropathy but people are more likely to get it if they are taking more than one supplement.

Does B6 deplete dopamine?

Vitamin B6 is a key player in the synthesis of many neurotransmitters, including GABA, serotonin, dopamine, noradrenalin, and histamine. B6 thus helps increase brain serotonin and dopamine levels, decreasing symptoms of anxiety, depression, fatigue, and pain.

Can B6 affect mood?

Because B6 is part of the process involved in making neurotransmitters like serotonin and GABA, a B6 deficiency can cause mood drops and changes. Research has shown that a B6 supplement can help to reduce irritability and even regulate mood swings associated with premenstrual syndrome (PMS).

Does vitamin B6 give you energy?

Vitamin B6 for sustained vigor

B6 or pyridoxine helps with muscle repair, combating anemia, brain function and much more. More importantly, B6 converts proteins, fats, and carbohydrates to glucose. The vitamin manages energy use too and prolonged energy can be expected when taking a B6 supplement.

Is depression a symptom of vitamin B6 deficiency?

Vitamin B-12 and other B vitamins play a role in producing brain chemicals that affect mood and other brain functions. Low levels of B-12 and other B vitamins such as vitamin B-6 and folate may be linked to depression.

The primary symptoms of vitamin B₆ deficiency are neurological, with identified brain-specific symptoms of B₆ deficiency including irritability, impaired alertness, autonomic dysfunction & convulsions (Dakshinamurti et al., 2013).

Does B6 deficiency cause seizures?

The only vitamin deficiency known to cause or worsen seizures is a deficiency of vitamin B6 (pyridoxine). This deficiency occurs mainly in newborns and infants and causes seizures that are hard to control. In some cases, the doctor may give the baby the vitamin through an IV while recording the EEG.

What is pyridoxine deficiency neonatal seizure?

Pyridoxine-dependent epilepsy (PDE) is a rare cause of stubborn, difficult to control, (intractable) seizures appearing in newborns, infants and occasionally older children. More than 200 patients have now been reported in the medical literature.

What does vitamin B6 do for epilepsy?

But after treatment with vitamin B6, the patients in the study who had the defective gene experienced a dramatic reduction in seizures, reducing their risk of incurring severe damage to the brain. The finding builds on existing research by the GOSH-ICH team who have previously uncovered two other defective genes.
