Brief Summary:
Young-onset dementia (YOD) is a devastating condition, and it produces substantial psychosocial impacts on individual's functioning and family's care burden. Alzheimer's disease (AD) dementia is the most common type in YOD. Medication treatment Response was limited and unsatisfactory. In recent years, repetitive transcranial magnetic stimulation (rTMS) has been considered an alternative for the improvement of cognition in older patients with cognitive impairment. This study aims to examine the effects and potential mechanisms of theta-burst stimulation (TBS) on cognitive function in individuals with young-onset AD.
Detailed Description:
The investigators apply the National Institute on Aging-Alzheimer's Association (NIA-AA) criteria to recruit the biomarker-defined, young-onset AD patients with intermediate-to-high levels of biological evidence. This is a randomized, sham-controlled, 2-way crossover study, and combined neuroimaging study of 18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) to further explore the potential mechanisms. This study will consist of two intervention periods. A total of 50 young-onset AD patients will be consecutively recruited and be randomized into one of two groups: active and sham stimulation (n = 25 per group) in every intervention period. Besides, 20 cognitively normal subjects will be recruited for neuroimaging comparison. Cognitive evaluation will be performed before and immediately after treatment at 2 weeks of TBS intervention, and 4 weeks after TBS. Data on functional neuroimaging will be also collected before and after TBS protocol.
