Active clinical trials for "Depressive Disorder"

To assess the prevalence of anxiety / depression in post- hospital for parents (mothers and fathers) of children with tracheotomy before the age of 1 year between 2000 and 2012.

Anxiety and depression are common comorbidities of chronic obstructive pulmonary disease (COPD). However, the exact prevalence is not known in China. COPD patients with anxiety and depression tend to have more severe symptoms and worse prognosis, but the related evidences are not strong enough. The study aim to investigate the prevalence and long-term outcome of anxiety and depression in COPD.

Patients with depression are frequently treatment resistant. Clinical manifestations of depression are various, but cognitive dysfunctions are commonly present. Many factors are involved in treatment resistance. As no biological marker is available, clinical markers could be considered in predicting response to antidepressive treatment. The aim of this study is to investigate the relation between the cognitive changes and the remission of depressive symptoms in patients with recurrent depression (Stage 2 of Thase and Rush classification). To explore the dynamics of cognitive dimension associated to clinical and functional remission, the investigators will observe neurocognitive functioning before and after introducing a new antidepressive therapy.

This research tries to investigate the validity and reliability of eye-tracking technologies by using different paradigms (eg. free-view, pro-saccade and anti-saccade) which served as a novel way of evaluating suicide risk among affective disorder patients including bipolar and unipolar depression. All the participants including health control will be assessed by clinical interviewing, self-report assessment, cognitive evaluation and eye-tracking task.

This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records

Results of the study and of 5 years follow up of depressed patients who participated in the study during 2014-2015. We will locate the participants and will interview them will use the same questionnaires to evaluate their depressive symptoms. We will also measure the time to relapse.

This study will try to provide a better understanding of the psychological, cognitive and electrophysiological factors that contribute to suicide in depressed patients.

Major depressive disorder (MDD) is a common mental illness with high prevalence and global burden. Previous studies revealed that over 70% patients in remission still had decreased quality of life, severe function impairment, low positive mental health score and poor coping ability. However, few studies focus on working and school age patients with MDD. A GBD survey showed that over 40% MDD patients are 15-50 years old. Therefore, we initiate the present multi-center cross-sectional survey to investigate the associations between clinical symptoms, cognitive function, occupational/study ability, and quality of life in Chinese working and school age population with MDD who are in remission.

Women who were able to benefit from psychiatric follow-up during the quarantine by tele-consultation have a lower risk of anxious and depressive symptoms than those who did not receive follow-up.

The objective of this study is to make a massive suicide risk and social behavior assessment in 24 pre-graduate education centers in Mexico City (approximately 30,000 students aged between 15 and 22 years), taking also into account other outcomes such as depression, anxiety, alcohol and drugs. For this, an app for Smartphone (MeMind) or a web platform (www.MeMind.net) will be used in which the participants will take a self-administered questionnaire, composed of several psychometric instruments. Our main hypothesis is that identification of suicide risk in the Mexico City's student community is feasible using their own smartphones and can serve as both a population screening tool for early specialist referral, as well as a tool for evaluating social behavior strategies and their relation to suicide behavior.
