Mental DisordersThe exact causes of attention deficit hyperactivity disorder (ADHD) are fully understood. A combination of biological and environmental factors is thought to be responsible for ADHD. Genes inherited from families from parents are a significant factor in developing this mental disorder. Although ADHD is not thought to be related to a single genetic default, research shows parents and siblings of a child with ADHD are four times likely to have ADHD themselves.Although research is inconclusive, various other causes have been suggested as playing a role in development of ADHD. These factors include premature birth, low birthweight and brain damage in the womb or in the early years of life. Environmental factors thought to be responsible for ADHD include drinking alcohol, smoking or misusing drugs while pregnant. Other factors include exposure to certain chemicals such as high levels of toxic lead at a young age. Although ADHD is considered a highly familial disorder, it is estimated that heritability factors account for only between 60% and 80%, therefore environmental and other modifiable factors play a significant role in susceptibility. Prevention of ADHD should focus on modifiable factors.Pregnancy complications are linked to ADHD. These can be prevented by promoting healthy pregnancies
