Attention Deficit Hyperactivity Disorder (ADHD)
Attention Deficit Hyperactivity Disorder (ADHD) is a mental condition that causes abnormal levels of hyperactivity and impulsive behavior. People with ADHD may have trouble concentrating on a task or sitting quietly for long periods.
Many people experience changes in inattention and energy levels. For someone with ADHD, it occurs more frequently and more frequently compared to those without this condition. This can have a significant impact on their studies, work, and home life
Both adults and children may have ADHD. This is a diagnosis approved by the American Psychiatric Association (APA). Learn about ADHD types and symptoms in both children and adults.
Widespread behaviors are associated with ADHD. Some of the most common are:
- having difficulty sitting still
- being easily distracted
- having trouble focusing or concentrating on tasks
- being forgetful about completing tasks
- interrupting people while they’re talking
Symptoms may be specific to various aspects of ADHD, such as hypersensitivity, agitation, or difficulty concentrating.
A person who is experiencing hyperactivity and impulsivity may:
- talk more than
- it is difficult to sit or sit quietly, for example, in class
- have trouble playing or carrying out tasks quietly
- find it hard to wait their turn
- interrupt others when they’re playing, speaking, or carrying out a task
Someone who is having difficulty focusing might:
- they are easily distracted by the little things that happen around them
- frequent mistakes or omissions while studying or working
- it is difficult to concentrate when listening, reading, or having a conversation
- have trouble organizing their daily tasks
- lose items frequently
Types of ADHD
To make ADHD diagnoses more consistent, the APA divides this condition into three categories or categories. These types are mainly inattentive, mainly hyperactivity-stimulating, and a combination of the two.
As the name implies, people with this type of ADHD have great difficulty concentrating, completing tasks, and following instructions.
Experts also believe that many children with inattentive type ADHD may not get a proper diagnosis because they are not disturbed in the classroom. Research shows that it is more common in women with ADHD.
Predominantly hyperactive-impulsive type
People with this type of ADHD primarily show high-speed and impulsive behavior. These include:
- interrupting when people are talking
- not being able to wait their turn
Although inattention is low in this type of ADHD, it can be difficult for people with mainly hyperactive-impulsive ADHD to focus on tasks.
Combined hyperactive-impulsive and inattentive type
This is the most common type of ADHD. People with this type of ADHD show signs of inattention and hypersensitivity. These include the inability to concentrate, the tendency to agitation, and above-average activity and energy.
The type of ADHD you or your child has will determine how it is treated. The type you have may change over time, and so may your treatment. Learn more about the three types of ADHD.
Despite how common ADHD is, doctors and researchers are not yet sure what causes this condition. It is believed to have a neurological origin. Genetics can also play a role.
Research has shown that dopamine deficiency is a risk factor for ADHD. Dopamine is a chemical in the brain that helps transfer signals from one nerve to another. It plays a role in stimulating emotional responses and movements.
Another piece of research is reliable evidence that suggests a structural difference in the brain. Findings indicate that people with ADHD have lower levels of gray matter. Gray areas of the brain include:
- muscle control
- decision making
