Active clinical trials for "Alzheimer Disease"

Focal repetitive transcranial magnetic stimulation (rTMS) has been applied to improve cognition in Alzheimer's disease (AD) with conflicting results. In this study we aimed to explore feasibility, safety and efficacy of excitatory rTMS of bilateral DLPFC applied with H-coil in AD in a pilot randomized, placebo-controlled, double-blind study.

The primary purpose of this study is to evaluate the safety and tolerability of SAGE-718 and its effects on cognitive and neuropsychiatric symptoms in participants with mild cognitive impairment (MCI) or mild dementia due to Alzheimer's disease (AD).

The purpose of this study is to assess the safety, tolerability, biomarker and cognitive efficacy of investigational products in subjects who are known to have an Alzheimer's disease-causing mutation by determining if treatment with the study drug slows the rate of progression of cognitive impairment and improves disease-related biomarkers. This is an analysis study for an MPRP: DIAN-TU-001 Master NCT01760005

Transcranial magnetic stimulation (TMS) is a noninvasive brain stimulation technique that is increasingly used for a growing number of research and clinical applications.Typically, this transient magnetic field is focally applied with a figure-of-eight coil that is carefully placed on the surface of the scalp over a targeted stimulation site. Patterned repetitive TMS (rTMS), such as theta burst stimulation (TBS) can produce long-lasting effects on neural activity and behavior beyond the stimulation period (Chou et al., 2015a; Fitzgerald et al., 2006). In general, high frequency (> 5 Hz) rTMS and its newer version, intermittent theta burst stimulation (iTBS), facilitate cortical excitability, whereas low frequency (about 1 Hz) rTMS and continuous theta burst stimulation contribute to opposite effects (Pascual-Leone et al., 2000; Huang et al., 2005; Wassermann and Zimmermann, 2012).Careful manipulation of the parameters comprising these patterned rTMS pulse trains can induce neuroplastic changes that resemble either long-term potentiation (LTP) or depression (Chen et al., 1997; Pascual-Leone et al., 1994). Early studies targeting the motor cortex helped elucidate which rTMS parameters promote particular responses and their neurophysiological underpinnings (Klomjai et al., 2015). In recent years, rTMS has been closely investigated to evaluate its potential to modulate cognitive functions in Alzheimer'sdisease (AD) and mild cognitive impairment (MCI). As compared to conventional excitatory rTMS protocols, iTBS leads to comparable effects with similar number of pulses but considerable shorter duration and lower intensity of stimulation (Bakker et al., 2015; Rossi, Hallett, Rossini, Pascual-Leone, & Safety, 2009). Recent literature also suggest that TBS has lower rates of reported adverse event (AE) compared to rTMS (Najib & Horvath, 2014). Therefore, iTBS is assumed to modulate cognitive function in people with cognitive impairments.

To evaluate the safety, tolerability, and long-term efficacy of bryostatin 1 (hereafter referred to as bryostatin) for the treatment of moderately severe Alzheimer's disease (AD).

The multiple ascending dose (MAD) design of the study is based on the aim to study safety, tolerability, PK and pharmacodynamics of selected doses of ACD856 in a limited number of healthy volunteers. ACD856 will be administered orally.

Objectives: The purpose of this study was to investigate the effects of high-frequency repetitive Transcranial Magnetic Stimulation (rTMS) in Alzheimer's Disease (AD). Methods: Twenty-seven AD patients aged ≥60 years were included in the study and divided into 3 groups (rTMS, Aerobic Exercise (AE) and control). All groups received pharmacological treatment. rTMS group (n=10) received 20 Hz rTMS treatment on bilateral dorsolateral prefrontal cortex, 5 days a week over 2 weeks, and AE group (n=10) received the moderate-intensity aerobic exercise for 50 min sessions, 5 days a week over 2 weeks. Control group (n=10) was only treated pharmacologically. Neuropsychiatric and behavioral status, cognition, balance, functional mobility, and quality of life, and functional brain changes were evaluated before and after the treatment.

Neuroinflammation is a significant component of Alzheimer disease (AD). Our data demonstrated compromised regulatory T cells (Tregs) phenotype and suppressive function in AD patients, skewing the immune system toward a proinflammatory status and potentially contributing in disease progression. Low dose interleukin-2 (IL-2) is now viewed as a very promising immunoregulatory drug having the capacity to selectively expand and restore functional Tregs. This study is a phase I open-label study to assess subcutaneous interleukin-2 (IL2) safety and potential efficacy as a Treg inducer in AD. 8 Alzheimer dementia patients with mild clinical dementia will be recruited into the study. The baseline cognitive status will be evaluated in these patients. Monthly five-day-courses of subcutaneous IL2 (1MUI/day) will be administered for a total of 4 months. Changes in Tregs from pre to post injections will be measured during the study period. The expected time participants will be in the study is 6 months.

Rationale: A prominent and degenerative motor symptom of dementia is paratonia that heavily affects quality of life. However, paratonia is poorly recognized and the diagnosis yet relies on subjective evaluation by caregivers. Objective: The primary aim of the proposed study is to develop a surface-electromyography-based method to objectively quantify paratonia in people with dementia. In addition, we aim to increase the understanding of the role of neuromuscular dysfunctions that contribute to paratonia. Study design: Cross-sectional study, in people of various ages and at older age with different levels of cognitive impairment and neuromuscular functioning, in which we will examine the association between their physical and cognitive function and neuromuscular outcome measures. Study population: Healthy young (18-30y, n = 40), middle-age (40-55y, n = 40) and older adults (>65y; n = 40). In addition, people with mild cognitive impairment (n = 40) as well as people with mild (n = 40), moderate (n = 40) and severe (n = 40) dementia. Main study parameters/endpoints: Cognitive function, physical function, neuromuscular function expressed by muscle- and brain activity as well as coordination.

The objective of this study is to evaluate the efficacy and safety of donepezil transdermal patch in patients with mild to moderate Alzheimer's disease. The primary objective is to demonstrate the non-inferiority of the test drug, IPI-301 (donepezil transdermal patch), to the comparator, Aricept tablet, after 24 weeks of treatment in patients with mild to moderate Alzheimer's disease in terms of improvement in cognitive function as assessed by the Alzheimer's Disease Assessment Scale - Cognitive (ADAS-cog) and in terms of global assessment as assessed by Clinician's Interview Based Impression of Change plus Caregiver Input (CIBIC-plus).
