Mental Health Problems
Autism is a mental condition that develops in early childhood. A change in the way autism was diagnosed led to a huge increase in the number of children who were diagnosed with autism in the 1990s, and through the present time.
What is Autism?
Autism is defined as a developmental disorder that appears before a child is three years old. Symptoms include an inability to interact socially (doesn’t use body language, doesn’t develop friendships, difficulty empathizing, no interest in sharing feelings or interests with others), lack of communication (can’t or won’t talk, and doesn’t use mime, sign language or other alternatives to communicate) and specific behavior patterns (doing the same thing over and over again, needing everything in a specific routine, and others).
An autistic child is essentially locked inside a world of their own, and have difficulty interacting with the world and people around them.
There is no known cause of autism. Researchers believe that autism does not have a single cause, but that a wide variety of genetic and environmental factors may interact to cause autism. Autism does often run in families, and several genetic abnormalities have been found which may play a role in the development of autism.
What is the Connection between Autism and MTHFR?
At this point, almost the only thing we known about autism and MTHFR is that they are connected. No large scale studies have examined the connection, and many children with none of the MTHFR anomalies have developed autism. However MTHFR anomalies are far more common in children with autism than they are among children who do not have autism. Or put another way, research shows that children who have MTHFR 677 are more likely to develop autism.
There are several other things about the connection between autism and MTHFR that we don’t know for certain, but that research says are likely true.
MTHFR 1298 on its own does not seem to increase a child’s risk of developing autism. However, when a child has both MTHFR 677 and MTHFR 1298 anomalies, their risk of autism is much higher than in children who just have the 677 anomaly.
Autistic children frequently have low levels of the antioxidant glutathione and the protease cysteine. MTHFR anomalies cause low levels of these important biochemicals. It is possible that the low levels of these chemicals is one of the direct causes of autism, and that children with MTHFR anomalies are more likely to develop autism because they do not have enough glutathione and cysteine in their bodies.
Whether or not a mother has MTHFR 677 may impact her children’s risk of developing autism. One study found that a mother with MTHFR 677 who does not take folic acid during her pregnancy is more likely to have an autistic child. Mothers with MTHFR 677 who take folic acid during pregnancy don’t have a higher risk of their child developing autism, which is another good reason for pregnant women to regularly take folic acid.
Children with autism who have MTHFR anomalies function just as well as children with autism who don’t have MTHFR anomalies. This means the MTHFR anomalies don’t seem to make most autism symptoms worse.
There are four specific symptoms that MTHFR may make worse. Children with autism and an MTHFR anomaly may be more likely to have trouble meeting someone else’s eyes, engage in self-injury behaviors, be overactive, or make complicated movements with their whole body.
My Child has Autism/I have Autism, Should They Be Tested for MTHFR?
If you or your child has autism then you may want to arrange testing for MTHFR. Preliminary research suggests that folate treatment for autism may provide benefits, and that long term folate treatment can lead to clinical improvement. Knowing whether or not you have an MTHFR anomaly can help you determine what kind of folate supplement would work best. Getting tested will also make you aware of whether or not you are at risk for other health problems caused by MTHFR anomalies.
It also might be worthwhile to get tested for MTHFR if autism runs in your family.
I Have MTHFR 677, Will My Children Have Autism?
Many people have MTHFR anomalies and never develop autism. Researchers are still trying to understand what other risk factors for autism are and how and why they lead to autism. If your child inherits MTHFR 677 then they will have a higher risk of developing autism, but that does not necessarily mean that they will get autism.
There are a few things you can do to reduce the risk of your child developing autism. First, if you are a mother-to-be, make sure you take folic acid supplements throughout your pregnancy. Second, have your child tests for MTHFR anomalies as early as possible. If they have inherited MTHFR 677 or MTHFR 677/1298, then starting them on folate supplements, with a doctor’s supervision, may reduce their risk of developing autism.
Schizophrenia is a severe and chronic mental illness that affects over 24 million people around the world. Doctors have known for years that there is a genetic component to schizophrenia. Recent studies have begun to shed light on this genetic component, and one of the genetic polymorphisms that contributes to schizophrenia is MTHFR 677.
What is schizophrenia?
Schizophrenia is a mental illness that is characterized by three kinds of symptoms: positive symptoms, or things caused by schizophrenia, include hallucinations, paranoia and disordered thoughts; negative symptoms, or things schizophrenia interferes with, include loss of interest in activities, lack of emotion, and loss of motivation; finally, cognitive symptoms are the ways schizophrenia interferes with comprehension. These include memory loss and difficulty understanding information.
Extreme cases of schizophrenia are severely disabling and many people with severe schizophrenia are institutionalized. Some medications may help with schizophrenia but for the most part it is a matter of treating the symptoms.
What is the connection between schizophrenia and MTHFR?
Numerous studies have found that people with MTHFR 677 are more likely to develop schizophrenia than those who do not have this MTHFR anomaly. Some studies have shown a possible connection between MTHFR 1298 and schizophrenia, but the connection, if it exists, is weak. Interestingly, the MTHFR 677 also affects the symptoms of schizophrenia. People with MTHFR 677 who develop schizophrenia are more likely to have severe negative symptoms and mild negative symptoms.
Aside from knowing that people with MTHFR 677 are more likely to develop schizophrenia little is known about the connection. One study has suggested that for some reason MTHFR 677 contributes to schizophrenia by lowering levels of dopamine, an important neuro-chemical, in the prefontal cortex.
Additionally, one small scale study found that children of mothers with MTHFR 677 were more likely to develop schizophrenia. This might be because of the way the genetic anomaly interferes with folic acid absorption or might be because children of mothers with MTHFR 677 are more likely to have MTHFR 677 themselves. The authors of the study noted that more research would need to be done to verify their results.
I have schizophrenia, should I get tested for MTHFR?
If you have several other health problems that can be caused by MTHFR as well as schizophrenia you should probably talk with your doctor about getting tested. Also, if your schizophrenic symptoms match the pattern of severe negative symptoms and mild negative symptoms, it might be worth getting tested. Even if you don’t get tested for MTHFR, talk with your doctor about starting folate treatments, because several other genetic anomalies that are involved in the same chemical processes as MTHFR can contribute to schizophrenia.
I have MTHFR 677, should I worry about developing schizophrenia?
If you have had any symptoms of schizophrenia and didn’t realize what they were, you should probably speak with a mental health professional. However, schizophrenia usually develops in childhood or the teen years. If you are over 25 and have no symptoms you probably won’t develop schizophrenia now. You should be aware of the increased risk of any children you have developing schizophrenia due to the possibility of their inheriting the genetic anomaly from you.
