Miscellaneous treatments for antipsychotic-induced tardive dyskinesia
The Cochrane database of systematic reviews (2018) · Meta analysis · n=1278
Studies were primarily of short (three to six6 weeks) duration with small samples size (10 to 157 participants), and most (61%) were published more than 20 years ago.
Multiple meta-analyses show small but statistically significant benefits for cognitive function in older adults and stroke prevention populations. Effect sizes are modest (SMD ~0.15-0.18). Benefits may be more pronounced in B-vitamin deficient populations.
Based on multiple meta-analyses including 2100+ participants showing benefits in mild dementia and memory. Effects modest and primarily in older adults or those with existing cognitive decline. Standardized extract (EGb 761) preferred.
