Input: The acetylcholinesterase inhibitor plus antipsychotic showed benefit over antipsychotic and placebo in the following outcomes. 1. Mental state - PANSS negative symptoms average end point score (2 RCTs, n = 31, MD -1.69 95% CI -2.80 to -0.57), PANSS General Psychopathology average end point score (2 RCTs, n = 31, MD -3.86 95% CI -5.40 to -2.32), and improvement in depressive symptoms showed at least by one short-term study as measured by CDSS scale (data skewed). 2. Cognitive domains - attention, (1 RCT, n = 73, MD 1.20 95% CI 0.14 to 2.26), visual memory (2 RCTs, n = 48 , MD 1.90 95% CI 0.52 to 3.28), verbal memory and language (3 RCTs, n = 42, MD 3.46 95% CI 0.67 to 6.26) and executive functioning (1 RCT, n = 24, MD 17.10 95% CI 0.70 to 33.50). 3. Tolerability - EPSE: AIMS, (1 RCT, n = 35, MD 1.50 95% CI 1.04 to 1.96). No difference was noted between the two arms in other outcomes. The overall rate of participants leaving studies early was low (13.6 %) and showed no clear difference between the two groups. The results seem to favour the use of acetylcholinesterase inhibitors in combination with antipsychotics on a few domains of mental state and cognition, but because of the various limitations in the studies as mentioned in the main text, the evidence is weak. This review highlights the need for large, independent, well designed, conducted and reported pragmatic randomised studies.
Output:

This review compares the effects of acetylcholinesterase inhibitors alone, or in combination with antipsychotics, compared with antipsychotics alone, or placebo plus antipsychotics. Adding acetylcholinesterase inhibitors with antipsychotics may improve the general psychopathology/negative symptomatology/depressive symptoms in people with schizophrenia. Also, the combination may be useful in improving the attention/reaction time and memory areas of cognition. The major limitation of the results was that most of the studies found were short-term studies. Considering the chronic, severe and enduring nature of schizophrenia, one cannot get a true picture unless well designed long-term studies are done. We hope that this review will highlight the need for more studies in this area.
