Parkinson's disease (PD) has become the second most prominent neurogenerative disorder relating to aging individuals. PD involves the loss of neurons containing dopamine in the midbrain and leads to a number of motor issues as well as non-motor complications such as cognitive and psychological abnormalities. The default mode network (DMN) is a complex brain network primarily active during rest...

Introduction Research on the influence of transcranial alternating current stimulation over alpha functional connectivity (FC) is scarce, even when it poses as a potential treatment for various diseases. This study aimed to investigate the effects of individual alpha frequency tACS (IAF-tACS) on FC within the default mode network (DMN) in healthy individuals, particularly following the triple...

Depressive disorders have been consistently associated with elevated levels of mind-wandering and self-focused negative rumination. Separate tracks of research have implicated brain structures within the default mode network (DMN) in both mind-wandering and depression. In this study, we hypothesized that diminished mind-wandering and fewer depressive symptoms would co-occur in individuals with...

Schizotypy is a personality trait characterized by subclinical expression of the signs and symptoms of schizophrenia. Maladaptive schizotypy is given the clinical designation of schizotypal personality disorder. Previous studies have shown that functional disturbance of the default mode network (DMN) is associated with maladaptive schizotypy. Working memory impairment is a particularly common...

The present study examined default mode network (DMN) neural connectivity patterns among adolescents. Next, we tested two critical markers of sleep health—duration and efficiency, in predicting neural connectivity patterns. Last, we investigated the latent DMN profiles’ predictive utility of internalizing and externalizing symptoms in youth.

BACKGROUND Neuropsychiatric symptoms (NPS) in mild cognitive impairment (MCI) are associated with accelerated Alzheimer's disease (AD) progression. Identifying multimodal brain imaging patterns associated with NPS in MCI may help understand pathophysiology correlates AD. METHODS This cross-sectional resting-state functional magnetic resonance imaging study included 376 participants: 130 MCI...

Kennen Sie das? Sie ärgern sich furchtbar über eine Kollegin und können sich gar nicht mehr aus dieser Negativspirale befreien. Genau dann ist der Zeitpunkt, das neuronale Netwerk zu aktivieren, um etwas zu entspannen, wieder leistungsfähig zu sein und die Dinge später, mit etwas Abstand, neu zu betrachten.

Given the increasing interest in the potential cognitive benefits of green tea, this study evaluated the efficacy of processed green tea products as nootropic agents. We conducted a 12-week, randomized, double-blinded, placebo-controlled trial to assess the effects of heat-treated green tea extract (HT-GTE) supplementation on memory performance in individuals with subjective memory impairment...

Mild Cognitive Impairment (MCI) is marked by a measurable decline in cognitive function that exceeds typical age-related changes but does not yet qualify as dementia. The brain's Default Mode Network (DMN) remains active during rest and plays a crucial role in introspective processes, such as memory retrieval and self-referential thinking. Resting-state functional magnetic resonance imaging...

Introduction Neurologic impairment is common in patients with acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. While patients with severe COVID have a higher prevalence of neurologic symptoms, as many as one in five patients with mild COVID may also be affected, exhibiting impaired memory as well as other cognitive dysfunctions. Methods To characterize the effect of COVID on the...
