Attention-deficit/hyperactivity disorder, or ADHD, is a neurodevelopmental condition that affects how your brain manages attention, organization, and impulse control. 

This condition affects a set of mental skills known as executive functioning. These skills help you plan, prioritize, and manage time, stay organized, and regulate your emotions.

While ADHD is often associated with children and commonly diagnosed in childhood, it can persist well into adulthood. In many cases, people do not receive a diagnosis until they are teenagers or adults.

The three types of ADHD:

ADHD, combined. This is the most common type. A child with this type is impulsive and hyperactive. They also have trouble paying attention and are easily distracted.

ADHD, impulsive/hyperactive. This is the least common type of ADHD. A child with this type is impulsive and hyperactive. But they don't have trouble paying attention.

ADHD, inattentive and distractible. A child with this type is mostly inattentive and easily distracted.

A mood disorder is a type of mental health condition where there is a disconnect between actual life circumstances and the person's state of mind or feeling. A mood disorder can negatively affect your ability to function normally. It can have serious consequences in all aspects of life, from personal to professional.

Children, teens, and adults can all have mood disorders. But children and teens don’t always have the same symptoms as adults. It’s harder to diagnose mood disorders in children. That's because they can't always express how they feel, and symptoms may look different in children from how they look in adults.

These are the most common types of mood disorders:

Major depression

Dysthymia

Bipolar disorder

Mood disorder linked to another health condition.

Substance-induced mood disorder. 

Anxiety disorders are common and treatable with individually tailored therapy and medication. There are several anxiety disorders: Panic Disorder, Obsessive-Compulsive Disorder, Post-Traumatic Stress Disorder, Generalized Anxiety Disorder, and Phobias.

Anxiety is a feeling of fear, dread, and uneasiness. It might cause you to sweat, feel restless and tense, and have a rapid heartbeat. It can be a normal reaction to stress. For example, you might feel anxious when faced with a difficult problem at work, before taking a test, or before making an important decision.
