Neurological Disorders and Treatments

Dementia is a highly prevalent condition worldwide. Its chronic and progressive presentation has an impact on physical and psychosocial characteristics and on public healthcare. Our aim was to summarize evidence from Cochrane reviews on non-pharmacological treatments for cognitive disorders and dementia.Review of systematic reviews, conducted in the Discipline of Evidence-Based Medicine, Escola Paulista de Medicina, Universidade Federal de São Paulo.Cochrane reviews on non-pharmacological interventions for cognitive dysfunctions and/or type of dementia were included. For this, independent assessments were made by two authors.Twenty-four reviews were included. These showed that carbohydrate intake and validation therapy may be beneficial for cognitive disorders. For dementia, there is a potential benefit from physical activity programs, cognitive training, psychological treatments, aromatherapy, light therapy, cognitive rehabilitation, cognitive stimulation, hyperbaric oxygen therapy in association with donepezil, functional analysis, reminiscence therapy, transcutaneous electrical stimulation, structured decision-making on feeding options, case management approaches, interventions by non-specialist healthcare workers and specialized care units. No benefits were found in relation to enteral tube feeding, acupuncture, Snoezelen stimulation, respite care, palliative care team and interventions to prevent wandering behavior.Many non-pharmacological interventions for patients with cognitive impairment and dementia have been studied and potential benefits have been shown. However, the strength of evidence derived from these studies was considered low overall, due to the methodological limitations of the primary studies.
