How is ADHD caused?

The most common cause of ADHD is still heredity. This means that if other people in the family have been diagnosed with ADHD, there is a very big chance that more people from the family will also be diagnosed with this condition. There are some studies and researches that are ongoing regarding how the environment can also affect the onset of ADHD.

Those who may discover the symptoms of ADHD later on in life may have ADHD all along, but it was not too pronounced when they were younger. People are recommended to know the characteristics of having ADHD and to get themselves checked for proper diagnosis and treatments.

Attention Deficit Hyperactivity Disorder (ADHD) is diagnosed in children and teenagers most times before the age of 12. ADHD causes symptoms such as persistent problems such as impulsiveness and difficulty paying attention. ADHD is unarguably the most common mental health disorder among children, but the exact cause remains unknown.

Research has shown that ADHD is influenced by several factors that can be categorized into genetic and environmental factors. Children with affected parents are more likely to have ADHD than children without affected parents. Alcohol intake during pregnancy, exposure to a toxic substance such as lead, and tobacco smoke during pregnancy can affect the development of the brain, which increases the risk of a child developing ADHD.
