La fatiga en el daño cerebral sobrevenido / Fatigue in patients with acquired brain damage

La fatiga es un síndrome multidimensional, complejo y frecuente en los pacientes con daño cerebral sobrevenido, influyendo negativamente en el proceso de neurorrehabilitación. Aparece desde etapas tempranas luego de la lesión y puede permanecer en el tiempo, recuperadas o no las secuelas del daño. La fatiga depende de circuitos neuronales superiores y se define como una percepción anómala de sobreesfuerzo. Tiene una prevalencia de 29% a 77% tras el ictus, 18% a 75% tras el traumatismo craneoencefálico (TCE) y 47% a 97% tras tumores cerebrales. La fatiga se asocia a factores como sexo femenino, edad avanzada, familia disfuncional, antecedentes patológicos específicos, estado funcional (p. ej. fatiga previa a la lesión), comorbilidades, estado anímico, discapacidad secundaria y uso de ciertos fármacos. Su estudio se realiza sobre todo a partir de escalas como la Escala de severidad de fatiga (Fatigue Severity Scale). Hoy en día existen avances en herramientas de imagen para su diagnóstico como la resonancia magnética funcional. En cuanto a su tratamiento, no existe aún terapia farmacológica definitiva, sin embargo, existen resultados positivos con terapias dentro de la neurorrehabilitación convencional, terapia lumínica y el uso del neurofeedback, estimulación eléctrica y magnética transcraneal. Esta revisión tiene como objetivo ayudar al profesional dedicado a la neurorrehabilitación a reconocer factores asociados modificables, así como terapias a su alcance para disminuir sus efectos nocivos en el paciente.

Fatigue is a complex, multidimensional syndrome that is prevalent in patients with acquired brain damage and has a negative impact on the neurorehabilitation process. It presents from early stages after the injury, and may persist over time, regardless of whether sequelae have resolved. Fatigue is conditioned by upper neuronal circuits, and is defined as an abnormal perception of overexertion. Its prevalence ranges from 29% to 77% after stroke, from 18% to 75% after traumatic brain injury, and from 47% to 97% after brain tumours. Fatigue is associated with factors including female sex, advanced age, dysfunctional families, history of specific health conditions, functional status (eg, fatigue prior to injury), comorbidities, mood, secondary disability, and the use of certain drugs. Assessment of fatigue is fundamentally based on such scales as the Fatigue Severity Scale (FSS). Advances have recently been made in imaging techniques for its diagnosis, such as in functional MRI. Regarding treatment, no specific pharmacological treatment currently exists; however, positive results have been reported for some conventional neurorehabilitation therapies, such as bright light therapy, neurofeedback, electrical stimulation, and transcranial magnetic stimulation. This review aims to assist neurorehabilitation professionals to recognise modifiable factors associated with fatigue and to describe the treatments available to reduce its negative effect on patients.
