Folic Acid and Autism

Tools

Story Updated: Feb 14, 2013

Here in the United States, women thinking about having a baby are encouraged to take folic acid prior to conceiving to reduce the risk of neural tube defects.

Now a large Norwegian study suggests folic acid supplements may also have a protective effect against autism.

It was proven that folic acid supplements around the time of pregnancy prevent neural tube defects.

The neural tube is the origin of the human brain in the fetus and closes very early in development and the neural tube defect is when this tube doesn't close properly.

The study included more than 85-thousand children born between 2002 and 2008. Researchers compared children whose mothers took folic acid supplements four weeks before...and eight weeks into their pregnancies with children whose mothers did not take the supplements.

A total of 270 children in the study were diagnosed with autism spectrum disorders.

114 with autism

56 with Asperger syndrome

And 100 with PDD-NOS, Cached - SimilarYou +1'd this publicly. Undo which means a child exhibits some behaviors seen in autism, but doesn't meet the criteria for having an Autistic Disorder.

Looking more closely at the data, researchers discovered that moms who took folic acid early in pregnancy had a 39% lower risk of having a child with autistic disorder although no association was found with Asperger syndrome or PDD-NOS

As always, it's important to talk to your doctor about prenatal vitamins with folic acid...before you get pregnant.

Guthrie Cardiovascular Center

Consistently ranked among the top 100 cardiovascular hospitals by Thomson Reuters, Guthrie cardiologists, cardiac surgeons, and vascular surgeons work together to ensure patients receive the most comprehensive care possible.

Offering cardiovascular care to the Twin Tiers for more than 40 years, Guthrie’s cardiac specialists and staff have offered the people of our region the most advanced diagnostic and therapeutic services possible, while earning national awards for quality and recognition for excellence.

Diagnostic & Non-Invasive Cardiology
Non-invasive cardiology includes all procedures that allow the cardiologist to obtain information about the heart without going through the skin or invading the body in any way. Many times these procedures are the first steps in evaluating a patient's condition. Guthrie provides diagnostic and non-invasive cardiology services, including multi-slice CT angiography, comprehensive mobile echocardiography services including stress echo, EKG, holter monitoring and nuclear stress testing to name a few.

Invasive & Interventional Cardiology
When non-invasive techniques don't provide all the answers, additional diagnostic procedures may be used to more clearly identify and treat cardiac problems. Within Guthrie’s Cardiac Catheterization Laboratories, invasive and interventional cardiologists offer subspecialty diagnostic and therapeutic services to evaluate and treat cardiac conditions without traditional surgery. Guthrie interventional cardiologists perform over 100 peripheral vascular interventions, such as carotid angioplasty and stenting, each year, with a 95% technical success rate.

Electrophysiology & Pacing
The heart's conduction system, the system that controls the rate and rhythm of the heartbeat, can develop problems that interfere with the heart's ability to function properly. Electrophysiology Laboratory team offers complete electrophysiology and pacing services for treatment of arrhythmias – from palpitations and syncope to atrial fibrillation to more specialized rhythm abnormalities.

Cardiac Surgery
Surgery plays an important role in a comprehensive cardiac program. Whatever the patient's needs, they can be met by the Guthrie’s cardiac surgery team. Guthrie’s Cardiac Surgery team provides a comprehensive scope of surgical procedures for the treatment of diseases of the heart and chest. Commonly treated conditions include ischemic heart disease, ventricular aneurysms, valve dysfunction, rheumatic heart disease, cardiac arrhythmia, trauma, cardiac tumors and infection.

Thoracic Surgery
Providing the advanced surgical techniques and oncologic therapies, thoracic surgery at Guthrie is dedicated to the prevention, early diagnosis and treatment of non-cardiac diseases of the chest. We are able to apply the modern techniques of minimally invasive procedures including video-assisted thoracic surgery (VATS) to many disease processes for the diagnosis and treatment of lung cancer and other chest diseases.

Vascular & Endovascular Surgery
Guthrie’s Department of Vascular and Endovascular Surgery offers a full spectrum of services – from life-saving procedures to repair ruptured aneurysms to elective procedures to prevent stroke, provide relief from claudication and address symptoms of venous disease. The latest therapies and minimally invasive endovascular treatment are offered by our experienced vascular team.
