Prenatal and Early Life Risk Factors of ADHD

Does birth trauma cause ADHD?

Prenatal complications are linked to ADHD. What role do prenatal and infant exposure play in ADHD? These are the difficult questions that parents often ask about ADHD.

Researchers continue to add new risk factors, such as maternal stress and lead poisoning, for ADHD during pregnancy and after birth. Much remains to be discovered. There is no clear causal link between many ADHD exposures. Some of these appear to result from ADHD genetics, while others could be contributing factors. It is important to note that ADHD doesn’t always result from the same risk factors. Most children exposed to these factors are healthy.

In the long run, it is increasingly clear that genes and environmental factors play an important role in brain development and behavior. This is particularly true during the early years of life. ADHD is a complex disorder that has no single cause. Nature and nurture, As well as the environment, can affect a child’s development.

ADHD is a condition that cannot be avoided. Prenatal and postnatal risks are unavoidable. If their child has ADHD, mothers may feel tempted to blame their child for past events. Science offers some comforting facts. ADHD is not a condition that can be guaranteed. Early treatment is often effective in reducing the impact of previous complications and improving outcomes.

Prenatal Risk Factors

Teratogens – Alcohol, smoking, and other substances

Teratogens can harm a developing fetus. Is it vital not to confuse association with causality? Although certain teratogens are associated with ADHD.


If you drink alcohol during pregnancy, it can cause a range of conditions called fetal alcohol syndrome diseases (FASD). These conditions share certain symptoms and characteristics with ADHD. 4

FASD can be misdiagnosed and overlooked. 5 6

Tobacco Use

According to a review of 12 large-scale studies in 2020, prenatal smoking can increase ADHD risks in children by over one-and-a-half times. Other studies have also shown that paternal smoking before and during pregnancy increases ADHD risk. 1 10 11

Smoking during pregnancy may be a cause of ADHD, but it is unlikely to be the causal factor. A study that took into account genetic factors showed that ADHD is not related to maternal smoking.

What causes ADHD? Culture Vs. Biology]

Drugs and Substances

  • Opioids According to a study in 2022 that included 3,000 kids, children who had mothers who used opioids during pregnancy were at greater risk of ADHD than children without mothers who did. 2 This same study found that ADHD risks increase when multiple substances are consumed, including tobacco and marijuana.
  • Acetaminophen The developing brain may be more sensitive to acetaminophen during certain times. FDA recommends that pregnant parents consult their doctor before taking pain medication.

However, we don’t know if genetic effects can cause these.

Maternal health problems

Maternal Metabolic Syndrome

Researchers are still trying to determine the link. The risk of these effects alone seems low, given the prevalence and severity of ADHD. These effects may help us to discover more about ADHD mechanisms.

Trauma or emotional stress

Stress or trauma in the mother can affect the behavior and temperament of children. Chronic prenatal anxiety can increase the risk of ADHD in children.

In 2018, a study found that stressed mothers during pregnancy have twice the risk of having a child with ADHD or conduct disorder as less stressed mothers.

Birth Trauma & Delivery Complications

Oxygen Deprivation

ADHD increases the risk of later life development due to inadequate oxygen supply and circulation at birth and in utero.

A 2012 study that included over 13,500 ADHD kids found that birth asphyxia was associated with a 26% increased risk of ADHD. A 47% increased risk of ADHD is linked to neonatal respiratory distress syndrome.

Delivery by C Section

It is unknown if the C-section plays a causal role in ADHD.

Low birth weight and prematurity

According to a 2018 meta-analysis that included 12 studies with 1,787 participants, extremely preterm babies and babies with very low birth weight are three times more likely to develop ADHD than healthy infants. A 2018 meta-analysis of 12 studies with 1,787 subjects found that extremely preterm infants and babies with low birth weight are three times as likely to develop ADHD as healthy babies.

ADHD Risk Factors – Early Life Exposures and Events

Lead and other Pollutants

Lead is well-known as a neurotoxin for children. Its link to ADHD is well established. 18 Even low levels of lead exposure can affect ADHD.

Recent research suggests that lead may be the cause of ADHD. In 2016, we examined the effects of HFE C282Y – a common genetic mutation – on ADHD symptoms among children. Children with ADHD showed more hyperactivity, impulsivity, and other ADHD symptoms compared to children without the modification.

It is difficult to explain why the results were found. The C282Y mutation spreads randomly in children and controls lead’s effects on the brain. Lead is not just associated with ADHD but also contributes to the cause. Numerous animal studies support this link.

ADHD and breastfeeding

It is unclear whether breastfeeding protects the developing brain from ADHD. It is unknown if breastfeeding can protect the developing brain against ADHD or if ADHD infants are harder to feed, so they breastfeed less. Advanced statistical methods confirmed this.

Head Injuries

A 2021 review of 24 studies involving 12,374 children found that head injuries can increase ADHD risk.

ADHD and head trauma have a complex relationship. ADHD increases the likelihood of head trauma. 25 Children who have ADHD are more likely to suffer serious head injuries.

Childhood Trauma

ADHD is more prevalent in traumatized children who have had adverse childhood experiences. It is also true that trauma increases the risk of ADHD.

Trauma can also exacerbate ADHD symptoms. Children with ADHD and trauma are more reactive. These children also require additional support.

Both trauma and ADHD have many common symptoms. A clinician with experience can determine whether a child has ADHD symptoms or a trauma effect.

ADHD Risk Factors – The Bottom Line

It is important to know that although research has connected ADHD with a number of risk factors in prenatal life and childhood, there are still many other things to consider.

  • The risk factors listed above are not necessarily causal.

We do not know if the risk factors have a causal effect or if they are artificially induced by unmeasured correlations (in particular, genetic confounding). Multiple risk factors are more important in a child’s health than one. Genetic risk is one risk factor. Even if there is a history of ADHD in the family, it does not mean that your child will have it.

  • Not all ADHD risk factors are created equal.

Many risk factors exist. Evidence can be “very strong” or “maybe.” The risk factors are often found in groups and add up, making it hard to determine whether an element has an ADHD connection. These risk factors are more common in disadvantaged groups.

  • The research has focused mainly on ADHD risk factors during pregnancy and maternal healthcare. A shift is taking place.

In the past, mothers have been blamed for psychiatry in a misguided way. Not all risks can easily be avoided, and fathers do not have to shoulder responsibility. Paternal support is one example. This can protect the health of both mothers and their fetuses. We are learning about the effects that paternal exposure to sperm and fetal health can have on sperm.

  • Even if a risk factor is associated with ADHD, its mere existence does not ensure a diagnosis.

Most children are unlikely to be affected by these risk factors. ADHD can develop even if another vulnerability or factor is present.

What Parents Can Do If their child has ADHD?

Parents might regret exposing children to ADHD risk factors. I advise caregivers not to dwell on past events. At the moment, it is still not clear what causes ADHD in children. You can still take positive steps to help your child with ADHD.

These strategies can help you as a parent reduce ADHD symptoms and manage them (and reduce them). They will also protect the well-being of your family.

Take part in Behavioral Parenting Training.

ADHD can cause challenging behaviors that overwhelm parents and lead to a poor relationship between parent and child. This can have an impact on the health and well-being of a child. Behavioral parent training (BPT) is an important part of ADHD treatment. BPT shows you how to respond to your child without worsening their behavior. BPT has a second benefit. BPT may increase the effectiveness of ADHD medications and even allow for a smaller dosage.

The key focus is on nutrition.

There are numerous links between ADHD nutrition and research. These links can help you and your family to take action.

  • Eat healthy food during pregnancy.
  • Omega-3 levels in children with ADHD are lower than those of children without ADHD. Supplementation may improve ADHD symptoms.
  • Consider an elimination-type diet if you suspect there’s a problem with your diet. Dietary changes can be difficult. It may be necessary to involve your entire family, or else your child will object. Also, it is important to choose the correct nutritional substitute. Therefore, you should only seek the advice of a nutritionist, behavioral counselor, and pediatrician to try to solve the problem.
  • Shop around the perimeter of your supermarket for fresh, nutrient-dense food. Make sure to avoid adding caffeine and sugars to your diet.
  • Check for nutritional deficiencies. ADHD is more common in children with low iron, zinc, or vitamin D levels. Recent research suggests that multi-nutrient supplementation can be beneficial to ADHD.

Encourage good sleeping habits.

ADHD children are more prone to sleep disorders that are behaviorally related. Sleep problems can include difficulty falling, staying, or getting to sleep. There are some cases of true endogenous sleep disorders in ADHD. However, they are rare.

Set up a routine for bedtime and ensure that your child sleeps at least 10 to 12 hours each night. Speak to your doctor about your child’s sleep problems to see if they relate to other disorders.

Get Your Child Moving

Exercise improves mood, health, and ADHD symptoms.

Exercise, nutrition, and sleep are the three most important lifestyle factors when addressing ADHD symptoms. They are not meant to replace professional treatment, but they can help reduce the amount of stimulant or psychotherapeutic medications your child needs.

Reduce your exposure to lead and other pollutants.

A lead test can benefit you and your child if you live in a high-lead area. Most medical lead tests cannot detect low levels of lead exposure, which have been associated with ADHD, according to scientific studies. It is still important to limit disclosure, even if your child has not been exposed.

A healthy diet, adequate iron levels, and Vitamin D may reduce the effects.

By taking these steps, you can reduce your exposure to pollutants at home and school.

  • Purchase a filter for water that will remove lead.
  • Install HEPA filters in the air ducts.
  • You should repair or prevent paint chips if your house was built before 1980. Do not let your children play on the soil near the house.
  • Learn how to protect yourself and your family from lead exposure.

Limit your screen time, and be sure to watch the quality.

The screen time research field is relatively new. The findings are still concerning. According to a 2018 study, teens who spend too much time on Facebook are more likely to experience ADHD symptoms than those who don’t.

While “gaming addiction” remains controversial, it is being scrutinized more. It is possible, although more research is needed, that ADHD children are more susceptible to problematic gaming because of their self-regulation issues and the high-reward nature of video games. Children who are exposed to violent content tend to be more aggressive.

Practice self-care

  • Manage stress and reduce stress in your daily life. Stress will cause your child to be more stressed. This can create a vicious cycle. Social support and self-compassion can help manage stress.
  • You should be aware of any stress or trauma that you may have experienced and seek help if needed. Inform your doctor and the doctor of your child about any traumas you’ve experienced.
  • Regular exercise, healthy eating habits, and good sleep hygiene are all essential.
  • If you have ADHD, depression, or other mental health problems, talk to your doctor.
