About 3127 MDD patients in the vortioxetine group and 3102 in the control group were analyzed. Primary efficacy outcomes were changes in Montgomery-Åsberg Depression Rating Scale, Clinical Global Impression-Improvement, and Clinical Global Impression-Severity scores, and the secondary outcome measure was cognition using the digit symbol substitution test scores.

Excluding the high-impact study did not cause much variation in the findings. There was a small but statistically insignificant improvement in cognition with vortioxetine compared to the control group. Vortioxetine had a favorable safety profile with only mild symptoms reported. The most commonly reported symptom was nausea.

Sahakian, Commander of the Most Excellent Order of the British Empire (CBE). Her pioneering research has advanced the understanding of brain mechanisms, including neurotransmitter modulation, and psychological processes involved in cognition, emotion, and motivation, leading to novel treatments for disorders such as Alzheimer's disease, attention deficit hyperactivity disorder, obsessive-compulsive disorder, and depression. She has also contributed to a better understanding of brain mechanisms underlying and psychological processes involved in these disorders. She has championed early detection of Alzheimer's disease through neuropsychological tools, such as the Cambridge Neuropsychological Test Automated Battery (CANTAB) paired associates learning (PAL) test and contributed to identifying cognitive and neural changes in Huntington's disease gene carriers. Beyond clinical research, Sahakian has influenced public health policy through initiatives such as the UK Government Foresight Project on Mental Capital and Wellbeing and the National Institute for Health and Care Excellence guidelines on gambling-related harms. She has also led efforts in neuroethics and public engagement, co-authoring accessible science books and participating in global forums. Recent research emphasises preventative psychiatry, including lifestyle interventions, such as diet, sleep, social connection, and lifelong learning as preventive strategies for cognitive decline and mental health problems.
