Late-life depression has been frequently associated with cognitive impairment. Several meta-analyses consistently suggested that a history of depression approximately doubles an individual's risk for developing dementia later in life. Neurodegeneration may play an important component in late-life depression. The pathophysiology behind the link between late-life depression and the subsequent development of dementia largely remains unclear, and should be heterogeneous. This highlights the need to identify specific neurodegenerative pathways involved in late-life depression, which will facilitate research on mechanisms and new treatments in the future. The recently published the National Institute on Aging and the Alzheimer Association (NIA-AA) criteria might provide new insights and frameworks to explore the patterns of neurodegenerative process in elderly depressed patients and to categorize them into different biomarker-based groups. In the present project, the investigators will recruit 40 patients with lifetime major depressive disorder, and 20 non-depressed cognitively normal comparison subjects. Alzheimer's disease pathology (A) was determined by measuring Aβ deposition by F-18 AV-45 PET, and neurodegeneration (N) was established by measuring hippocampal volume using MRI. Individuals were categorised as A-N-, A+N-, A+N+, or suspected non-Alzheimer's disease pathophysiology (A-N+, SNAP). All subjects will further undergo F-18-THK-5351 image study to detect underlying tau pathology. By doing this, the investigators will elucidate the neurodegenerative pathophysiology behind the link between depressive disorder and the subsequent development of dementia.
The purpose of this study is two-fold: 1. To identify the best smartphone data features (based on keyboard, sensor, voice/speech data) that correlate with mood, anxiety, and cognitive assessments in patients with Major Depressive Disorder (MDD) and Bipolar Depression (BD). 2. To identify the best smartphone data features (based on keyboard, sensor, voice/speech at a) that predict relapse and remission in MDD or BD.
The investigators will conduct an 8-week, non-randomized, open-label study of brexpiprazole in 20 persons with bipolar I or II disorder, depressed mood state. Primary aim will be to assess if brexpiprazole is associated with a reduction in depressive symptom severity using the Montgomery-Asberg Depression Rating Scale (MADRS). Secondary aims will include an assessment of the following in patients with bipolar disorder taking brexpiprazole: manic symptoms, cognition, safety and tolerability of brexpiprazole, and quality of life. Subjects will be discontinued from the study if any of the following conditions occurs: change in diagnosis to other than bipolar I or II disorder, development of active suicidal or homicidal ideation with plan and intent, worsening of mood symptoms, that in the opinion of the investigators requires discontinuation, pregnancy, development of severe life-threatening medical condition, involuntary psychiatric hospitalization or incarceration.
During this project the investigators will develop and pilot test a companion intervention for fathers (Fathers and Babies-FAB), to supplement the Mothers and Babies Course (MB) that provides stress and mood management tools for home visiting clients. Focus groups with prior study participants, their male partners, and home visiting staff will be used to develop the FAB curriculum and protocol. FAB text messages aim to improve the mental health of the male partner and help him support his partner's mental health. Feasibility, acceptability, and outcome measures will be supplemented with assessments of fathers' mental health and partners' relationships. Participant assessments will be conducted at baseline, 3 and 6 months in this uncontrolled pilot study. The public health significance and innovation of this project is substantial. If the investigators are able to integrate MB-TXT and MB-DAD into home visiting programs and generate improved mental health outcomes for home visiting clients and their partners, the investigators will be prepared to replicate this intervention across home visiting programs nationally at a time when home visitation as a service delivery model for families with infants and young children is rapidly proliferating through federal funding.
To investigate the effect of patient mood before spinal anesthesia on post spinal puncture headache and backache
This study evaluates the vestibular activity in major depression patients and healthy controls using the rotatory test and electronystagmography.
The proposed study is to evaluate the safety and initial efficacy of MRgFUS for patients with treatment-refractory Major Depression. This study is designed as a prospective, single arm, nonrandomized study. Assessments will be made before and after MRgFUS for adverse events related to treatment, for clinical symptom relief, and quality of life (QoL). The target in the brain chosen for ablation will be the anterior limb of the internal capsule (i.e 'capsulotomy').
Hazardous alcohol consumption is common among people suffering from depression. There are effective Internet interventions that target hazardous alcohol consumption or depression separately but none that combine these online interventions without the involvement of a therapist. This study aims to evaluate the effects of combining an Internet intervention targeting hazardous alcohol consumption with one for depression on drinking and depressive symptoms.
This project is aimed at enhancing the effectiveness and scalability of the Mothers and Babies 1-on-1 Course (MB) among home visiting programs. MB is a manualized 12-session postpartum depression prevention intervention guided by cognitive-behavioral therapy and attachment theory. Each session lasts 15-20 minutes and is delivered as part of a regularly scheduled home visit. Previous MB trials suggest that the intervention is less successful for women who exhibit smaller changes in hypothesized intervention mechanisms and less fully engaged in completion of personal projects. This study will determine the feasibility and acceptability of conducting MB-TXT, in which home visiting clients receive MB supplemented by a series of weekly text messages focused on skill reinforcement, personal project reminders, and self-monitoring of depressive symptoms. The investigators will also calculate a preliminary effect size that could be used to calculate sample size necessary for a future fully powered randomized controlled trial that examines MB-TXT efficacy. The investigators will use a stepped wedge design—a form of randomized controlled trial that involves sequential, but random, roll-out of the intervention over multiple time periods. The investigators have created two HV program clusters. Both clusters will initially implement MB 1-on-1 and will recruit MB participants for one quarter (i.e., three months) before crossing over to recruit MB-TXT participants for one quarter. MB-TXT's core curriculum is identical to MB 1-on-1 and adds a series of text messages throughout the curriculum. Feasibility and acceptability data will be collected from clients and home visitors to assess percentages of received text messages, home visitor adherence to sending texts at specified intervals, and clients' perceptions of text message utility and clarity. If the investigators are able to integrate MB-TXT and home visiting programs and generate improved mental health outcomes for clients, the investigators will be prepared to replicate this intervention across home visiting programs nationally at a time when home visiting as a service delivery model is rapidly proliferating via federal Maternal Infant and and Early Childhood Home Visiting (MIECHV) program funding.
