Background: Considering the high cost of Magnetic Resonance Imaging and the high risk of radiation exposure to growing children from Computed tomography scans, we aim to evaluate the neuroimaging findings in children with chronic headaches, determine the frequency of significant remediable pathologies, and establish the need for neuroimaging.
Methodology: This is a cross-sectional study of clinical data and neuroimaging findings in 41 children who were imaged in a tertiary hospital and a private diagnostic center in Abuja on account of chronic headaches. Twenty-two children were referred for brain Computed Tomography scan while 19 had brain Magnetic resonance Imaging. Collected data was statistically analyzed using SAS software version 9.3 with the level of significance set at 0.05.
Results: The age range of patients was 4 -18years.Thirty-three patients (80.5%) had chronic primary headaches while eight (19.5%) patients had additional "red flag" indications. Normal findings and extracranial lesions accounted for 89.5% of MRI (17/19) and 72.7% (16/22) in CT. Intracranial lesions were seen in 75% of patients with "red flag" and 6.1% of patients with primary headache with significant differences (0.0001) between the subsets. The commonest abnormalities were chronic sinusitis (17.1%) and intracranial tumors (9.6%) with no significant difference in the overall neuroimaging findings across the age groups. Chronic sinusitis was found predominantly in adolescent females (85.7%).
Conclusions: Neuroimaging has a low yield of significant remediable intracranial lesions in children with chronic headaches without additional "red flag" symptoms thereby necessitating the call to reconsider the use of neuroimaging with a view to imaging gently.

Long-Term Impact of Using Mobile Phones and Playing Computer Games on the Brain Structure and the Risk of Neurodegenerative Diseases: Large Population-Based Study.
J Med Internet Res
January 2025
Department of Neurology, West China Hospital, Sichuan University, Chengdu, China.
Background: Despite the increasing popularity of electronic devices, the longitudinal effects of daily prolonged electronic device usage on brain health and the aging process remain unclear.
Objective: The aim of this study was to investigate the impact of the daily use of mobile phones/computers on the brain structure and the risk of neurodegenerative diseases.
Methods: We used data from the UK Biobank, a longitudinal population-based cohort study, to analyze the impact of mobile phone use duration, weekly usage time, and playing computer games on the future brain structure and the future risk of various neurodegenerative diseases, including all-cause dementia (ACD), Alzheimer disease (AD), vascular dementia (VD), all-cause parkinsonism (ACP), and Parkinson disease (PD).
Brain Function Outcomes of Recent and Lifetime Cannabis Use.
JAMA Netw Open

Laboratory of NeuroImaging, National Institute on Alcohol Abuse and Alcoholism, Bethesda, Maryland.
Importance: Cannabis use has increased globally, but its effects on brain function are not fully known, highlighting the need to better determine recent and long-term brain activation outcomes of cannabis use.
Objective: To examine the association of lifetime history of heavy cannabis use and recent cannabis use with brain activation across a range of brain functions in a large sample of young adults in the US.
Design, Setting, And Participants: This cross-sectional study used data (2017 release) from the Human Connectome Project (collected between August 2012 and 2015).
A case of severe TBI: Recovery?
Appl Neuropsychol Child

Department of Psychology and Neuroscience Center, Brigham Young University, Provo, USA.
Chronic stage neuropsychological assessments of children with severe TBI typically center around a referral question and focus on assessing cognitive, behavioral, and emotional functioning, making differential diagnoses, and planning treatment. When severe TBI-related neurological deficits are subtle and fall outside commonly assessed behavioral indicators, as can happen with theory of mind and social information processing, they can go unobserved and subsequently fail to be assessed. Additionally, should chronic stage cognitive, behavioral, and emotional assessment findings fall within the average to above average range, a child experiencing ongoing significant unassessed severe TBI-related subtle deficits could be mistakenly judged to have "recovered" from their injury; and to be experiencing no significant ongoing residual neurological deficits.

In Alzheimer's disease (AD), the accumulation of neuropathological markers such as amyloid-β plaques, neurofibrillary tangles, and cortical neurodegeneration occurs over many years before overt manifestation of cognitive impairment. There is thus a need for neuropsychological markers that are indicative of pathological changes in the early stages of the disease. Intra-individual cognitive variability (IICV), defined as the variation of an individual's performance across cognitive domains, is a promising neuropsychological marker measuring heterogeneous changes in cognition that may reflect these early pathological changes.
