Could exposure to china's lead-based paint products cause autism in children?

Could exposure to china's lead-based paint products cause autism in children?

Unlikely : The mental impairments associated with lead toxicity are qualitatively different from the autism spectrum, so childhood exposure to these compounds while bad, would not yield autism. There is room for speculation on whether a mothers exposure to toxic substances in life could cause the genetic codon changes in her eggs that are later identified in autistic kids. ...Read more

Which stage in human fertilisation/conception/pregnancy period does susceptibility to environmental factors that may contribute/cause defects start?

Before conception: The woman is born with all the eggs she will ever have and they mature over her lifetime until either released or lost.All exposure to chemicals/radiation/illnesses during a woman's life impact the egg quality.Once released to conception, the environmental influences on outcome are continuous.Some are time specific (thalidomide-5-7 wks) some are continuous (alcohol). ...Read more

Does isoimmunization and anemia cause slow social development?

Does isoimmunization and anemia cause slow social development?

Generally no.: Isoimmunization is an immune-mediated process that is caused by mother antibodies crossing the placenta and targeting the babies red blood cells (this is also called rh disease). The resulting fetal anemia can be mild to severe. Whether normal growth and development are compromised is dependent upon the severity and length of the anemia and any associated cognitive dysfunction which may occur. ...Read more

Could exposure to agent orange to a child's dad or grandfather cause learning disorders in future generations?

Could exposure to agent orange to a child's dad or grandfather cause learning disorders in future generations?

Epigenetic factors,: Like the herbicide in agent orange can change the function, but not the structure or sequencing of genes in germ cells (eggs & sperm). The functional differences may be passed to future generations. The veterans' administration position paper on this subject is on http://www.Vva.Org/committees/agentorange/position-paper-birth-defect.Pdf. The mind institute at uc davis has done animal studies, also. ...Read more

Can the rubella vaccine cause autism? I’ve heard stories about the MMR vaccine, which includes rubella, can cause
autism or other problems. Is there any evidence that this could be true?

In : In 1998, a doctor by the name of andrew wakefield published a study in the lancet journal implicating a relationship between the MMR vaccine and autism. Wakefield's study was found to be fraudulent, the data was manipulated and the study was retracted by the lancet in 2004. Dr. Wakefield even had his medical license revoked for unethical practices. After this study was published in 1998, it spurred tons of research looking in to whether the relationship between vaccines and autism could be true. There have been well over 100 large-scale studies and evidence reviews looking at the relationship between vaccines and autism and every single one of those studies has shown that vaccines (including the mmr) do not cause autism. Below, i've linked to 3 websites that discuss this controversy and the research involved in-depth. I will also add that i vaccinated my own child on the schedule recommended by the center for disease control and american academy of pediatrics without any hesitation. ...Read more

Possible neurological effects to baby breastfed during mother's stomach-cancer treatment? (chemo etc.?) obvious mental retardation only or subtle too?

Possible neurological effects to baby breastfed during mother's stomach-cancer treatment? (chemo etc.?) obvious mental retardation only or subtle too?

Difficult to answer: Many things make a difference here - what chemo is being used, how long exposure, etc. Remember, your baby is going through tons of development of every organ system and chemo will harm this. While i applaud your wanting to breast feed, i can't imagine risking your child's development, intelligence and risk for cancer in the future just to continue breast feeding. Effects could be devastating. ...Read more

Help! need to know if there's any evidence that delayed onset noise induced hearing loss and tinnitus can manifest itself years after severe noise exposure?

Yes: Noise induced hearing loss is cumulative. It may not be noticeable until you get beyond a certain threshold. Or, you could be getting an overlap between noise induced hearing loss and age associated hearing loss (presbycusis). See an ENT doc to sort things out. ...Read more

Is it possible to diagnose a child with both autism & aphasia? Child has Family history of autism, numerous autism symptoms, and prior brain injury.

Is it possible to diagnose a child with both autism & aphasia? Child has Family history of autism, numerous autism symptoms, and prior brain injury.

Name that diagnosis: Your question is very complex as is your child. It is possible to have both diagnoses. However it would be very difficult to diagnose both separately. I am wondering if the head injury is also related. I think you need to see a pediatric development and behavior specialist to help decide what to do. The treatment for the language delays will be about the same for either cause. ...Read more
