Abstract
Cognitive function impairment as a consequence of a head/brain injury represents a wide-ranging and heterogeneous spectrum of disorders. Seriousness of such disorders, as well as their duration and extent of recovery, depend on both the severity of the trauma itself (i.e., on a primary process) and consequent events inside the skull (i.e., on a secondary impact).
Neuropsychological evaluation of a person with a head/brain traumatic impairment usually finds deficiencies in the following areas: attention/concentration, memory/learning, and executive functions. Furthermore, also cognitive domains, such as thinking, language, visuospatial abilities, mathematics, etc., may be affected.
Additional problems in emotional living and behavior (irritability, impulsiveness, apathy, loss of motivation, lack of interest in the others) can even lead to psychotic disorders (mania, touchiness, delusions) in some cases.
