Attention deficit hyperactivity disorder (ADHD) is a mental disorder of the neurodevelopmental type.

It is characterized by problems paying attention, excessive activity, or difficulty controlling behavior which is not appropriate for a person's age.

These symptoms begin by age six to twelve, are present for more than six months, and cause problems in at least two settings (such as school, home, or recreational activities).

In children, problems paying attention may result in poor school performance.

Although it causes impairment, particularly in modern society, many children with ADHD have a good attention span for tasks they find interesting.

A symptom (from Greek σύμπτωμα, "accident, misfortune, that which befalls", from συμπίπτω, "I befall", from συν- "together, with" and πίπτω, "I fall") is a departure from normal function or feeling which is noticed by a patient, reflecting the presence of an unusual state, or of a disease.

A symptom is subjective, observed by the patient, and cannot be measured directly, whereas a sign is objectively observable by others.

For example, paresthesia is a symptom (only the person experiencing it can directly observe their own tingling feeling), whereas erythema is a sign (anyone can confirm that the skin is redder than usual).

Symptoms and signs are often nonspecific, but often combinations of them are at least suggestive of certain diagnoses, helping to narrow down what may be wrong.

In other cases they are specific even to the point of being pathognomonic.

The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.

The brain is located in the head, usually close to the sensory organs for senses such as vision.

The brain is the most complex organ in a vertebrate's body.

In a human, the cerebral cortex contains approximately 15–33 billion neurons, each connected by synapses to several thousand other neurons.

These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells.

Learning is the act of acquiring new, or modifying and reinforcing existing, knowledge, behaviors, skills, values, or preferences which may lead to a potential change in synthesizing information, depth of the knowledge, attitude or behavior relative to the type and range of experience.

The ability to learn is possessed by humans, animals, plants and some machines.

Progress over time tends to follow a learning curve.

Learning does not happen all at once, but it builds upon and is shaped by previous knowledge.

To that end, learning may be viewed as a process, rather than a collection of factual and procedural knowledge.

Learning produces changes in the organism and the changes produced are relatively permanent.

Therapy (often abbreviated tx, Tx, or Tx) is the attempted remediation of a health problem, usually following a diagnosis.

In the medical field, it is usually synonymous with treatment (also abbreviated tx or Tx).

Among psychologists and other mental health professionals, including psychiatrists, psychiatric nurse practitioners, and clinical social workers, the term may refer specifically to psychotherapy (sometimes dubbed 'talking therapy').

The English word therapy comes via Latin therapīa from and literally means "curing" or "healing".
