A further definition of text

A text is a structure transmitting knowledge which is represented by means of a linguistic structure. In a specialized text we can appreciate different levels, in particular the linguistic level (terms and structure) and the knowledge level (knowledge being transmitted).

The knowledge units convey information about the specific field of knowledge. They can be more or less complex, and may sometimes belong to other (non-linguistic) systems (for instance, acronyms, or figures).

Attention-Deficit/Hyperactivity Disorder (ADHD)

ADHD is one of the most common neurobehavioral disorders of childhood and can persist through adolescence and into adulthood. Currently the causes are unknown.

A person with ADHD has a chronic level of inattention, impulsive hyperactivity, or both such that daily functioning is compromised. The symptoms of the disorder must be present at levels that are higher than expected for a person's developmental stage and must interfere with the person's ability to function in different settings (e.g., in school and at home).
