A study of 1,300 students found that those who trained with Lumosity showed significant improvements in a battery of cognitive assessments. The effects were dose-dependent, with longer training sessions leading to greater gains.
Lumosity presents new data on measuring cognitive training improvements, finding larger doses lead to greater gains and training gains strongly predict transfer effects. A reliability assessment of the BPT shows it is a powerful tool for evaluating the effectiveness of cognitive training.
A new study by Kessler Foundation scientists investigates the neural correlates of cognitive fatigue in multiple sclerosis using functional magnetic resonance imaging and diffusion tensor imaging. The findings suggest a 'fatigue-network' in persons with MS, which could help define the pathophysiology of this symptom.
Researchers found greater BOLD activation in brain areas typically activated by MS patients during task performance when exposed to warmer temperatures. This suggests neural inefficiency and may impact independence, education, employment, and daily activities.

A review of 8 trials found no long-term benefits from cognitive enhancers like donepezil and rivastigmine for patients with mild cognitive impairment. These medications were associated with increased nausea, diarrhea, vomiting, and headaches, but no cognitive improvement.
A form of cognitive behavior therapy (CBT) called exposure and ritual prevention has been shown to augment antidepressant treatment for obsessive-compulsive disorder (OCD), with 80% of patients responding compared to 23% on antipsychotics. The therapy works by retraining the brain's habit-forming circuitry to unlearn compulsive rituals.

The study found that dancers who practiced with marking were judged more highly on their movements and sequences, indicating improved fluidity and memorization.
Recent studies have found chemotherapy-associated adverse neurological effects, including vascular complications and neuropathic pains. Chemotherapy triggers changes in ion channels on dorsal root ganglia, resulting in secondary changes that affect neurogenesis and plasticity.
Recent research questions the idea of discrete brain areas for specific cognitive functions like mind-wandering and attention reorienting. Instead, studies suggest that brain activation is due to the release of suppression rather than additional task-related processes.
