Filter by:Three groups of subjects will be included: 20 subjects in the healthy control group, 20 subjects in the MDD electroacupuncture (EA) intervention group, and 20 subjects in the MDD waiting-list group (participants will receive no treatment within 4 weeks). The temperature and infrared thermography (IRT) images of the facial acupoints of three groups will be recorded by an infrared thermal-imaging camera. The average facial temperature and acupoints temperature will be analyzed and compared within 3 groups. In addition, the correlation between facial infrared radiation characteristics of MDD patients and emotional changes will be explored. Besides, the relative specificity of the two meridians will be investigated.
The purpose of this study is to evaluate the efficacy and safety of Ammoxetine hydrochloride enteric-coated tablets in subjects with depression.
This is a study that will test a predictive biomarker algorithm based on results from a previous study. The goal of this study is to integrate clinical, imaging, EEG, and molecular data across 8 sites to predict treatment outcome for patients experiencing a major depressive episode (MDE).
Participants with Major Depressive Disorder (MDD) or Generalized Anxiety Disorder (GAD) will use a prescribed digital therapeutic for 8-10 weeks, and will complete depression and anxiety measures during this time. After the treatment period, participants will be followed monthly for 12 months.
The goal of this proposal is to examine the influence of feedback timing on learning and brain function in individuals with moderate-to-severe traumatic brain injury (TBI), with and without depression.
This study intends to carry out a prospective, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of subanesthetic sevoflurane for treatment-resistant depression.
The purpose of this study is to identify the variations in gut microbiota compositions between two subtypes of major depressive disorder.
The aim of this study is to evaluate the effects of transranial pulse stimulation (TPS) on young adults with symptoms of depression in Hong Kong. Methods: This is a single-blind randomized controlled trial design with two-armed repeated measures, and participants will be followed up at a 3-months post-stimulation period. Eligbility: 1) aged 18 or over; 2) able to understand/read Chinese; 3) HAM-D-17 score of ≥ 8; 4) provide written informed consent. Exclusion criteria includes: 1) individuals being prescribed a DSM-5 diagnosis other than major depressive disorder (e.g., bipolar affective disorder or schizophrenia); 2) Alcohol or substance dependence; 3) Concomitant unstable major medical conditions or major neurological conditions such as brain tumour, brain aneurysm; 4) Haemophilia or other blood clotting disorders or thrombosis; 5) Significant communicative impairments; 6) Participants with metal implant in brain or treated area of the head; 7) Participants who undertook corticosteroid treatment within the last six weeks before first TPS treatment; 8) Pregnant or breastfeeding women. Recruitment: A total of 30 subjects will be recruited from collaborative NGOs and PolyU and randomly assigned into the Intervention Group (TPS) and the Waitlist Control Group on a 1: 1 ratio. Intervention: All participants (both TPS group and the waitlist control group) will receive six 30 minute-TPS sessions (300 pulse in each session, total: 1800 pulse) in 2 weeks' time. Outcome measurements include depression, anhedonia, instrumental activities of daily living, cognition and neuroimaging.
This study will examine the biological factors that may modulate the relationship between depression and the development of Alzheimer's disease (AD). Since the direction of causation between depression and the biological factors associated with AD is unknown, the only way to understand cause and associated risk is to treat the depressive symptoms and examine the effects on AD biomarkers. The study involves an FDA-approved treatment for major depressive disorder. It will compare the SSRI antidepressant escitalopram with placebo. The hypothesis is that a reduction in depressive symptoms will be associated with a normalization of CSF AD biomarkers as well as peripheral inflammatory markers. This research would contribute to fundamental knowledge about potentially modifiable risks of Alzheimer's disease (AD).
The aim of this study is to test the hypothesis that low-frequency rTMS (LFR) works as well as the established intermittent thetaburst rTMS (iTBS) treatment for treatment resistant depression (TRD).
