The associations between screen time and mental health in adolescents: a systematic review.

Background: Adolescents have extensive use of screens and, they have common complains related to mental health. Here a systematic review was done to understand the association between screen time and adolescent's mental health.

Method: This review was conducted in compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses - PRISMA.

The Association between Screen Time and Attention in Children: A Systematic Review.

Electronic media pervade modern life. Childhood is a crucial period for attentional development and the screen exposure time is increasing. This review aimed to understand the association between screen time and attention of children with typical development.

Acute exercise increases BDNF serum levels in patients with Parkinson's disease regardless of depression or fatigue.

Studies have consistently reported a decreased level of brain-derived neurotrophic factor (BDNF) in individuals with Parkinson's disease (PD). The benefits of exercise on BDNF levels are well-documented in humans, however, the effects of acute exercise are inconclusive in neurological disorders. In addition, there are no studies investigating a precursor molecule - proBDNF - and its comparison to patients with vs.

Can fatigue predict walking capacity of patients with Parkinson's disease?

Unlabelled: Although fatigue is an expressive symptom of Parkinson's disease (PD), few studies have investigated the association between fatigue, mobility and walking capacity of these patients.

Objective: To investigate whether fatigue is an independent factor associated with mobility and the walking capacity in patients with PD.

Methods: Forty-eight patients with PD (22 with fatigue) were tested for mobility and their walking capacity: Timed Up and Go (TUG), 10-Meter Walk Test (10MWT) at usual and fastest speed, and 6-Minute Walk Test (6MWT).

IL-6 serum levels are elevated in Parkinson's disease patients with fatigue compared to patients without fatigue.

To investigate the influence of interleukin-6 (IL-6) and soluble tumor necrosis factor receptors (sTNFR) in fatigued Parkinson's disease (PD) patients. Forty-four PD patients were evaluated, and fatigue was assessed with the Parkinson Fatigue Scale. Logistic regression analysis was used to evaluate the contribution of disease severity scores and cytokine levels on fatigue scores.
