Researchers have uncovered novel insights into how brain function disruptions related to cerebrovascular disease (CeVD) interact with Alzheimer’s disease (AD) pathology to impact neurodegeneration and cognition in older adults.

University of Toronto researchers have developed a flexible, biodegradable electrode capable of stimulating neural precursor cells (NPCs) in the brain—a device capable of delivering targeted electrical stimulation for up to seven days before it dissolves naturally.

A new study from Karolinska Institutet and Mayo Clinic has revealed important insights into brain degeneration in dementia with Lewy bodies (DLB). This research, published in JAMA Neurology, could help doctors better monitor and treat this serious brain disease.

Epilepsy is associated with poor brain health, with a consistent deleterious effect seen on cognitive and motor function and mental health, according to a study published online Dec. 31 in the Journal of Translational Medicine.

There may be a link between hearing impairment and an increased risk of developing Parkinson’s according to research led by Lancaster University.

The human working memory (WM) is the cognitive system responsible for the temporary storage and processing of information vital to task completion. In contrast, human long-term memory (LTM) is the system that holds information for prolonged periods of time, organizing acquired knowledge into distinct categories, such as facts, events, skills and habits.

Prenatal exposure to glucocorticoids is associated with some mental disorders in offspring, such as mood, anxiety, and stress-related disorders, according to a study published online Jan. 3 in JAMA Network Open.

Disability is a significant risk factor for lower quality of life (QOL) and increased caregiver burden among children with epilepsy and their caregivers, according to a study published in the February issue of Epilepsy & Behavior.

A study published in Science reveals new mechanisms through which the brain controls natural actions. The results challenge some of the classical views about how the motor system works and open up possible new applications in neurorehabilitation and robotics.

The processing of optical information in the retina of the eye, where the light-sensitive photoreceptors and the first nerve cells are located, is one of the most energy-intensive processes in the organism, especially in view of the low relative weight of the retina.
