Neuroimaging – News and Features

According to a new modeling study, the high number of CT (computed tomography) scans carried out in the United States in 2023 could cause 5 percent of all cancers in the country, equal to the number of cancers caused by alcohol.

Researchers identified a neural circuit defect in ASD that impairs the ability to redirect attention, crucial for social learning. The study suggests that interventions targeting this circuit could help improve attention-switching in ASD children.

A UCLA-led study reveals that children with chromosome 22q11.2 deletion syndrome show brain hyperconnectivity before puberty and under-connectivity after. This shift, linked to synapse loss, may drive autism and schizophrenia risk.

A study identifies key brain activity patterns involved in urinary incontinence in stroke survivors. Using fMRI, the research shows how strokes disrupt brain regions critical for bladder control, offering new insights into potential therapies.

A recent study reveals that individuals with cannabis use disorder exhibit elevated dopamine levels in brain regions tied to psychosis. Using brain imaging, researchers showed that long-term cannabis use can disrupt normal brain processes.

A clinical trial of tolebrutinib, an investigational oral Bruton’s tyrosine kinase inhibitor, demonstrated a 31% delay in the onset of six-month confirmed disability progression in patients with non-relapsing secondary progressive multiple sclerosis.

A new study reveals that increased blood flow to the hippocampus, a brain region crucial for memory, causes stiffness. This discovery offers insight into how reduced blood flow might impact hippocampal health.

A new study provides insights into Tourette syndrome by analyzing individual brain cells. Researchers found key changes, including a loss of interneurons, metabolic stress in medium spiny neurons, and increased inflammatory activity in microglia.

Investigators have validated a test that can accurately predict which patients with prostate cancer are at higher risk of developing long-lasting urinary side effects after receiving radiation therapy.

Researchers have found that early life adversity leads to reduced white matter connectivity in the adolescent brain, impacting cognitive performance. However, factors like positive parenting can serve as protective influences.
