Pharmacotherapy for treatment of attention deficits after non-progressive acquired brain injury. A systematic review
Abstract
To systematically review the effectiveness of medications used to improve attention in people with non-progressive acquired brain injury. A systematic review. MEDLINE, EMBASE, CINALH, PUBMED and PsychINFO databases were used to identify studies published between 1987 and 2008 meeting the following criteria: studies with subjects older than 18 years; diagnosis of new onset or previous acquired brain injury; medication given to improve attention and use of outcome to measure attention. Studies involving subjects in low arousal states or with neurogenerative conditions were excluded. The studies were categorized into three evidence levels: I - Randomized controlled trials; II - Prospective studies, controlled trials with methodological limitations; and III - Retrospective studies, clinical case series. Forty-seven articles were identified on initial search. Twenty-six met the pre-specified criteria. Five articles were assessed as meeting the level I evidence criteria, 12 were level II studies and 9 were level III studies. Methylphenidate can improve information processing speed but not all attention aspects in some people after traumatic brain injury. There is weak evidence for use of dopamine agonists to improve neglect/inattenti...Continue Reading
