Introduction and objective: We present a diagnostic decision tree for the correct use of neuropsychological evaluation techniques in head injury. Our aim is to avoid extensive, intensive use of unnecessary tests and measurements or lapses into diagnostic error which often accompany cognitive dysfunction when 'superficial' 'undirected' studies are done.
Development: It is essential to select the neuropsychological, neuroconductal and psychosocial evaluation tests which are most suitable in each case and establish a reliable diagnosis of the functional, cognitive, emotional and psychosocial conditions of the patient. The decision tree for neuropsychological evaluation is a guide to assist professionals so that they may adequately examine the functional changes which can occur as a consequence of traumatic brain damage, adapted to each point in its evolution and taking into account factors which may influence neuropsychological evaluation.
Conclusion: The evaluation of consequences of trauma includes evaluation of the gravity of the head injury, and the neuropsychological, neuroconductal and functional evaluation of the patient.
