Very interesting! B Vitamin deficiencies. My husband, at age 52 was going through despair thoughts and I told him, "MENopause", and get B complex shots. So he did. You give it to yourself, no pain. About once a month or twice a month. Those who smoke, drink may need it twice a month to start. My husband did not smoke or drink. He never had a seizure. BUT he sure needs his shots!
Vaccines for children, seizures are possible. High temps, fever can bring on seizures. Aneurysm in the brain can do it. Also build up of stress with an aneurysm.
