20 Health Conditions That Mimic ADHD
By Edward Group
ADHD, or attention deficit hyperactive disorder, is diagnosed through mere observation of symptoms and not by any sort of scientific testing. There are no brain scans, blood tests, or biological readings to determine the presence of ADHD, just a myriad of behavioral and psychological symptoms.  Although many of the symptoms arise from an underlying cause, most doctors who diagnose children and adults with ADHD tend to overlook the underlying health factors in lieu of prescribing an ADHD medication. Whether concentration issues are the result of an allergy, lack of physical or mental stimulation, or is the result of nutrient malabsorption, misdiagnosis is bound to contribute to the sharp increase in ADHD diagnoses.
Conditions That Mimic ADHD
There are many biological, physiological, emotional, and medical conditions that may cause symptoms similar to those ascribed to ADHD. Here are just a few of the issues that might be influencing ADHD-like behavior.
Blood sugar issues are common, especially in children who regularly consume high-carbohydrate foods. Highly processed foods often encourage a blood sugar crash. Low blood sugar, or hypoglycemia, can cause irritability, lack of concentration and focus, and low energy levels — classic “ADHD” symptoms.  Although research hasn’t shown that sugar causes ADHD, it has been shown to boost observable symptoms.
Allergic reactions to synthetic dyes, preservatives, and other food chemicals can lead to symptoms associated with ADHD.   One of the first steps to take if you’re experiencing concentration or focus problems is to avoid synthetic, processed, and non-organic food whenever possible.
3. Learning Disabilities
There are many reasons why a child (or even an adult) may have trouble learning. Perhaps they learn at a slower rate. On the other hand, maybe they can pick up new information faster than those around them, resulting in extra downtime for daydreaming and restlessness. Whatever the cause, undiagnosed issues can result in an ADHD diagnosis. Perhaps all that’s required to improve symptoms is a change of environment or teaching method.
4. Hyper- or Hypothyroidism
Both the underproduction and overproduction of thyroid hormones can cause energy imbalances, mood disorders, and concentration issues. Anyone who is currently experiencing such problems should have their thyroid evaluated before diving into traditional ADHD therapies. 
5. Hearing and Vision Issues
If a child has trouble seeing the board or hearing the teacher, this could affect how they perform in the classroom. This can affect adults as well, and many older adults are reluctant to tell their doctor about hearing or eyesight issues. Remedying poor eyesight or hearing may be helpful for avoiding an ADHD diagnosis.
6. Lead Poisoning
People with abnormal levels of lead in their body are more likely to suffer from lower IQ, attention deficits, and negative work and school performance. Studies indicate that lead may be one of the leading culprits for increasing hyperactivity in children. 
Genetic Conditions That Mimic ADHD
Certain genetic diseases, like diabetes and heart disease, may also increase ADHD symptoms. People who have been diagnosed with ADHD should take inventory to determine if they’re instead suffering from any one of the following conditions.
People who have a family history of diabetes should make sure they are keeping their blood sugar in check. High blood sugar, whether genetic or not, could present symptoms related to ADHD, including anxiety, poor focus, and aggression. 
8. Heart Disease
Any sort of heart abnormality can affect blood, oxygen, and nutrient flow to the brain. Adults and children alike should look into their heart health if on the verge of being diagnosed with ADHD, especially if heart disease runs in the family.
While anemia isn’t always inherited, the condition, marked by a lack of red blood cells, is often a result of genetics. Anemia can cause a decreased level of oxygen to the brain, possibly leading to brain dysfunction.
10. Bipolar Disorder
Many health experts believe that 85% of children with bipolar disorder meet the criteria set for ADHD.  For children suffering from bipolar, mood swings can occur throughout the day, and many doctors, parents, and teachers misjudge these occurrences as ADHD.
