“…Abnormalities in the frontal lobe can cause abnormalities in movement, memory, and other functions ( 31 ). The hippocampus is closely related to the functions of learning, memory, emotion, and movement, and abnormalities in the hippocampus can cause abnormalities in its functions ( 32 , 33 ). The results of the study showed that the CBF values of the caudate nucleus, basal ganglia, hippocampus, frontal lobe, temporal lobe, and other brain regions were lower than those in healthy children.…”

ObjectiveTo explore the application of three-dimensional pseudocontinuous arterial spin labeling (3D-PCASL) perfusion imaging in the brains of children with autism and to understand the characteristics of cerebral blood perfusion in children with autism.MethodsA total of 320 children with autism (160 men and 160 women) aged between 2 and 18 years and 320 age- and sex-matched healthy children participated in the study. All children were scanned by 3.0 T magnetic resonance axial T1 fluid-attenuated inversion recovery (FLAIR), T2 FLAIR, 3D-T1, and 3D-PCASL sequences. After postprocessing, cerebral blood flow (CBF) values in each brain region of children with autism and healthy children at the same age were compared and analyzed. Furthermore, CBF characteristics in each brain region of autistic children at various ages were determined.ResultsThe CBF values of the frontal lobe, hippocampus, temporal lobe, and caudate nucleus of children with autism are lower than those of healthy children (P < 0.05). Additionally, as the ages of children with autism increase, the number of brain regions with decreased CBF values gradually increases. A receiver operating characteristic (ROC) analysis results show that the CBF values of the frontal lobe, hippocampus, temporal lobe, and caudate nucleus can distinguish children with autism [area under the ROC curve (AUC) > 0.05, P < 0.05].ConclusionThe 3D-PCASL shows lower brain CBF values in children with autism.Clinical Trial Registrationwww.ClinicalTrials.gov, identifier: ChiCTR2000034356.

“…The functions of the frontal lobe include movement, memory, judgment, analysis and thinking, etc. Therefore, abnormalities of the frontal lobe can lead to abnormalities in movement, memory, and other aspects (Alsultan, Alaboudi, Almousa, Alajaji, & Bashir, 2020; Oades, 1998; Rolls et al, 2020; Ronan, Alexander‐Bloch, & Fletcher, 2020; Schmidt & Poole, 2020). The results show that the iron content in the frontal lobe of children with ADHD is lower than that of healthy children, and the decrease of iron content may also lead to neurodevelopmental abnormalities in the frontal lobe, and ultimately lead to behavioral abnormalities in children with ADHD.…”

To investigate the feasibility of quantitative susceptibility mapping in children with attention‐deficit hyperactivity disorder (ADHD), 53 children with ADHD aged 5–16 years were prospectively selected as the study group and 49 healthy children matched with age and gender were selected as the control group. All children underwent magnetic resonance imaging conventional sequence, 3D‐T1, and enhanced T2*‐weighted magnetic resonance angiography (ESWAN) sequence scanning. The iron content of brain regions was obtained through software postprocessing, and the iron content of brain regions of children with ADHD and healthy children was compared and analyzed to find out the characteristics of the iron content of brain regions of children with ADHD. The iron content in frontal lobe, globus pallidus, caudate nucleus, substantia nigra, putamen, and hippocampus of children with ADHD was lower than that of healthy children (p < .05). There was no significant difference in the content of iron in the left and right brain regions of children with ADHD (p > .05). The volume of frontal lobe and hippocampus of children with ADHD was lower than that of healthy children (p < .05). Iron content in brain areas such as globus pallidus, caudate nucleus, hippocampus, and putamen could distinguish children with ADHD (Area under curve [AUC] > 0.5, p < .05). Quantitative susceptibility mapping showed decreased iron content in some brain regions of children with ADHD.

“…There is a paucity of data on tDCS' effect on cognitive function during RF. AlSultan et al [44] assessed the effect of tDCS on three brain areas including the right dorsolateral prefrontal cortex (DLPFC), posterior parietal cortex (PPC), and cerebellum on cognitive function and obtained safety data in healthy adults during RF. Forty-two healthy, right-handed participants were randomly assigned to one of the six stimulation groups.…”

The medical literature on health aspects of Ramadan fasting (RF) is widely spread in many journals of varying access, making it less readily available to those interested in the subject. We performed a nonsystematic review of the international literature from a major online database (PubMed in 1 year [2020]). The search term “Ramadan fasting” was used, and relevant literature was narrated in a concise thematic account excluding diabetes. The publications spanned fundamental, clinical, ethical, professional, cultural, and advocacy facets. The publications predictably crossed the conventional disciplinary lines and geographical locations and appeared in journals with different access systems. The contents are presented under the emerged themes depending on the retrieved literature. This year, the basic coverage included changes in physiology, nutrition during Ramadan. However, the clinical issues included a more comprehensive range such as the impact of RF on the liver and gut, and endocrine conditions such as hypothyroidism and adrenal insufficiency. Coverage also included chronic kidney disease, maternal health and fetal well-being, cardiovascular medicine, nature and function of eyes, and neurological conditions, especially epilepsy. Sports medicine and athletes' well-being received somewhat prominent coverage. Other researchers focused on documenting patients' and health-care professionals' perceptions, attitudes, and practices during Ramadan. Health aspects of RF received a sustained academic interest with a broad spectrum in 2020. This narrative provides a scoping overview to help researchers and clinicians catch up quickly with state-of-the-art science today.
