Effects of transcranial direct current stimulation over frontal, parietal and cerebellar cortex for cognitive function during fasting in healthy adults.

Background: Transcranial direct current stimulation (tDCS) is a neuromodulation tool used to modify the cognitive function in subjects. There is a paucity of data on tDCS' effect on cognitive function during Ramadan fasting. This paper aims to assess the effect of tDCS of three brain areas, including the right dorsolateral prefrontal cortex (DLPFC), posterior parietal cortex (PPC), and cerebellum on cognitive function, and obtain safety data in healthy adults during Ramadan fasting.

Safety of Transcranial Direct Current Stimulation of Frontal, Parietal, and Cerebellar Regions in Fasting Healthy Adults.

(1) Background: Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation modality that has been investigated in a large number of studies in terms of it is effects on brain function, safety of use, and future implications. The principal aim of this study was to investigate the safety of 1.5-mA tDCS of three brain areas, that is, frontal, partial, and cerebellar cortices, in fasting healthy individuals during the month of Ramadan.

Body Size Misperception and Overweight or Obesity among Saudi College-Aged Females.

The aim of the study was to investigate the associations between perceived and desired body size and overweight and obesity among college-aged females. A multistage stratified cluster random sample was used to select 907 healthy females from a major Saudi public university. The Stunkard Figure Rating Scale (FRS) was used for body size assessment.

Associations of self-esteem with body mass index and body image among Saudi college-age females.

Purpose: To examine the association of self-esteem with the body mass index (BMI), perceived body image (BI), and desired BI of college-age Saudi females.

Methods: A cross-sectional study was conducted with 907 randomly selected females using a multistage stratified cluster sampling technique. Self-esteem and BI were assessed using the Rosenberg Self-Esteem Scale and Stunkard Figure Rating Scale, respectively.
