Irrational Thinking Patterns in Depression and Anxiety
What are cognitive distortions? These are irrational thinking patterns or unhelpful, negative ways of thinking that can lead to anxiety and depression.

Background Research on Depression
Major depression is the most common and severe psychiatric disorder across the world. Recently, the World Health Organization reported that the COVID-19 pandemic had triggered a massive increase in the number of people with anxiety and depression. About a quarter of patients do not respond adequately to the treatments available.Dr. Lim Lee Wei, assistant professor in the School of Biomedical Sciences, HKUMed and a former Lee Kuan Yew Research Fellow in Singapore, reported in 2015 that deep brain stimulation of the prefrontal cortex in the brains of animals could improve memory function and relieve depressive symptoms. However, this technique, also known as deep brain stimulation, is invasive and requires surgery to implant electrodes in the brain, which may cause side effects such as infections and other post-operative complications.
Research Findings and Significance
A team of Hong Kong researchers headed by Dr. Lim Lee Wei; Dr. Leanne Chan Lai-hang, Associate Professor in the Department of Electrical Engineering, CityU; Professor Chan Ying-shing, Dexter H C Man Family Professor in Medical Science, Professor of the School of Biomedical Sciences, Associate Dean (Development and Infrastructure), HKUMed, and Director of the Neuroscience Research Centre, HKU, have been looking for alternative ways to treat neuropsychiatric diseases. They discovered that the non-invasive stimulation of the corneal surface of the eye (known as transcorneal electrical stimulation, or TES) that activates brain pathways, resulted in remarkable antidepressant-like effects and reduced stress hormones in an animal model for depression. Furthermore, this technique induced the expression of genes involved in the development and growth of brain cells in the hippocampus.In related experiments, Yu Wing-shan, PhD student, and other research members from the School of Biomedical Sciences, HKUMed, investigated whether this approach could be used to treat Alzheimer’s disease, a common type of dementia with no definitive cure. They found that this non-invasive stimulation in mice drastically improved memory performance and reduced beta-amyloid deposits in the hippocampus, which is one of the hallmarks of Alzheimer’s disease.
Can Inflammatory Diet Increase Depression, Frailty Risk?
Inflammatory diet can increase depression and frailty in adults. Adding some anti-inflammatory foods to the diet can keep depression and frailty at bay.

"These research findings pave the way for new therapeutic opportunities to develop novel treatment for patients suffering from treatment-resistant depression and dementia. Nevertheless, clinical trials must be conducted to validate the efficacy and safety," remarked Prof. Chan Ying-shing.
