Neuroscience can involve research from many branches of science including those involving neurology, brain science, neurobiology, psychology, computer science, artificial intelligence, statistics, prosthetics, neuroimaging, engineering, medicine, physics, mathematics, pharmacology, electrophysiology, biology, robotics and technology.

– These articles focus mainly on neurology research.

– Definition of neurology: a science involved in the study of the nervous systems, especially of the diseases and disorders affecting them.

– Neurology research can include information involving brain research, neurological disorders, medicine, brain cancer, peripheral nervous systems, central nervous systems, nerve damage, brain tumors, seizures, neurosurgery, electrophysiology, BMI, brain injuries, paralysis and spinal cord treatments.

Summary: Researchers have identified specific neurological biomarkers for ADHD in the brain.

The study revealed those with ADHD had abnormal connectivity in brain areas associated with memory processing and auditory processing, and thinning of the brain’s cortex.

Researchers analyzing the data from MRI exams on nearly 8,000 children have identified biomarkers of attention-deficit/hyperactivity disorder (ADHD) and a possible role for neuroimaging machine learning to help with the diagnosis, treatment planning and surveillance of the disorder.

Diagnosis relies on a checklist completed by the child’s caregiver to rate the presence of ADHD symptoms.

After exclusions, Lin’s study group included 7,805 patients, including 1,798 diagnosed with ADHD, all of whom underwent structural MRI scans, diffusion tensor imaging and resting-state functional MRI.

The researchers performed a statistical analysis of the imaging data to determine the association of ADHD with neuroimaging metrics including brain volume, surface area, white matter integrity and functional connectivity.

In the patients with ADHD, the researchers observed abnormal connectivity in the brain networks involved in memory processing and auditory processing, a thinning of the brain cortex, and significant white matter microstructural changes, especially in the frontal lobe of the brain.

“Our study underscores that ADHD is a neurological disorder with neuro-structural and functional manifestations in the brain, not just a purely externalized behavior syndrome,” she said.
