Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder which primarily affects children of young age. Although adults can be affected too, ADHD is more commonly seen among children of 6-8 years. As the symptoms are initially mild, it is difficult to diagnose this disorder.

ADHD Causes

The exact cause is unknown, but researchers suggest several things that may lead to it, including:

● Genetics, wherein ADHD runs in families.

● Poor nutrition, infection, drinking, smoking, and substance abuse during pregnancy can affect a baby’s brain development which may cause Attention deficit hyperactivity disorder.

● Premature birth, especially before 37 weeks

● Damage to the front of the brain can cause problems controlling impulses & emotions

● Toxins such as lead may affect a child’s brain development

In fact, the exact cause of ADHD cannot be accurately determined and can only be estimated based on some tests and charts. However, the bigger concern is the proper diagnosis of the right condition so that treatment following the same is accurate enough.

ADHD Diagnosis & Testing

Doctors use the American Psychiatric Association’s guidelines, which are based on how many symptoms a person has and how long they’ve had them. To confirm a diagnosis of ADHD or learning differences, a child may take a battery of tests to check their neurological and psychological status. The test may include

• A medical & social history of both the child and the family

• A physical exam and neurological assessment that includes screening of vision, hearing, and verbal and motor skills

• An evaluation of intelligence, aptitude, personality traits, or processing skills.

• A scan called the Neuropsychiatric EEG-Based Assessment Aid (NEBA) System, which measures theta and beta brain waves.

ADHD Treatment

There are several approaches to treating ADHD and typically a combination therapy is considered the most effective treatment.

1. Medications-

Stimulants are the most preferred and prescribed medications for ADHD as they are found to balance the chemicals in the brain called neurotransmitters. They are given alone or in combination with other medicines like antidepressants.

2. Therapy -

These treatments focus on changing behaviour and it includes cognitive brain therapy (CBT), psychotherapy, behaviour modification and family therapy.

3. Lifestyle changes-

A healthy and nutritious diet, a good sleep routine and positive attitude, etc., are found effective along with the other therapies. They can control and minimize ADHD symptoms.

Conclusion

Attention deficit hyperactivity disorder (ADHD) is a chronic behaviour disorder usually diagnosed in early childhood. The impact of ADHD varies for each individual but with correct diagnosis, medications and lifestyle management it can help in controlling the condition and allow them to lead a normal life.
