  • Title: [Pharmacotherapy of the cognitive sequelae secondary to traumatic brain injury].
    Author: Riós-Romenets S, Castaño-Monsalve B, Bernabeu-Guitart M.
    Journal: Rev Neurol; ; 45(9):563-70. PubMed ID: 17979087.
    Abstract:
    AIM: To review and correlate the most common cognitive disorders secondary to traumatic brain injuries (TBI), the neurobiology of these deficits and their possible modulation by neuropharmacological means. DEVELOPMENT: As of a complex cascade of injuries to the brain, patients with TBI may experience alterations that affect the cognitive domain on different levels and to varying degrees, the most common being alteration of the level of alertness; slowing of the speed at which information is processed; attention, memory and learning deficits; language and communication disorders; and impaired executive functions. Brain damage may be caused by a range of pathological mechanisms, such as focal bruising, diffuse axonal damage, cytotoxic damage and neurotransmitter excitotoxicity. Certain pharmacological agents have an effect on the cognitive functions. Pharmacological agents that improve cognitive performance include dopaminergic agents, psychostimulants, some antidepressants and cholinesterase inhibitors. CONCLUSIONS: Studies into the pharmacological neuromodulation of the cognitive disorders secondary to TBI are currently in the early stages. The information we have available on the neurochemical bases of cognition and cognitive disorders due to TBI suggest that the most important goals of pharmacological intervention in this group of patients are the stimulation of the catecholaminic and cholinergic functions.
