The exact cause of attention deficit hyperactivity disorder (ADHD) is not fully understood, although a combination of factors is thought to be responsible. Genetics. ADHD tends to run in families and, in most cases, it's thought the genes you inherit from your parents are a significant factor in developing the condition. Research shows that parents and siblings of a child with ADHD are more.
A particular interest has been on disorders that afflict children at an early age and persist throughout their life, such as Autism, now known as Autism Spectrum Disorder (ASD) and Attention Deficit and Hyperactivity Disorder (ADHD), previously referred to as Attention Deficit Disorder (ADD). The impact of these disorders has instigated extensive research into their signs and symptoms, causes.

Attention deficit hyperactivity disorder (ADHD) is a mental disorder of the neurodevelopmental type. It is characterized by difficulty paying attention, excessive activity, and acting without regards to consequences, which are otherwise not appropriate for a person's age. Some individuals with ADHD also display difficulty regulating emotions or problems with executive function.

Approximately 3% to 10%.

Attention Deficit Hyperactivity Disorder Wolraich and Baumgaertel in “The Prevalence of Attention Deficit Hyperactivity Disorder Based on the New DSM-IV Criteria” (1996) observe that ADHD is “the most common mental disorder in children” (p.168).From a parent’s perspective, ADHD is a troubling disorder feared due to its adverse effects on the behavior of children.
Attention deficit hyperactivity disorder (ADHD) is a common and impairing neurodevelopmental disorder, which frequently co-occurs with autism spectrum disorder (ASD). Both disorders are highly heritable and recent studies report a substantial degree of overlap in genetic risks for ADHD and ASD. The overall objective of this thesis is to examine the clinical co-occurrence and shared genetic.
