    Cause of ADHD

    The exact cause of ADHD is unknown. The theories state that there are changes in the brains of people with the ADHD. It is not caused by home or school situations or by poor parenting.


     There is no single test used to diagnose ADHD. It is diagnosed after a child has shown some or all of symptoms of ADHD on a regular basis for more than 6 months. The diagnosis of ADHD involves the gathering of information from several sources, including school, caregivers and parents. A specialist in childhood development disorders will consider how a child's behavior compares with that of other children the same age. The specialist will also do a physical exam to look for any medical problems that may affect a child's behavior. ADHD in adults is diagnosed using a similar process.


     Although there is no cure for ADHD, treatment can help control symptoms. There are several types of treatments available. some of the available options are called stimulant drugs that stimulate the secretion of certain neurotransmitters tht helps to control the symptoms  such as Amphetamines and Methylphenidates .

    Also antidepressants and drugs like Atomoxetine can be used but it works slower than stimulants do and may take several weeks before they take full effect. These may be good options if your child can't take stimulants because of health problems or if stimulants cause severe side effects.

  • Behavioral  therapy:

    Learning behavior management techniques is considered to be an essential part of any successful ADHD treatment program. Most experts agree that combining medication treatments with extended behavior management is the most effective way to manage ADHD in children and adolescents.
