Cancer patients with vitamin D deficiency under palliative care reported a decreased need for opioids to control pain and reduced symptoms of fatigue when given vitamin D supplementation.
A new study reveals adults with ADHD have an increased risk of developing nervous system, respiratory, musculoskeletal, and metabolic diseases. ADHD was also associated with a slightly increased risk of Parkinson's disease, dementia, and cardiovascular disease.
Children show improved ability in their math skills when they are trained to practice visual working memory and reasoning tasks.
A link has been identified between psychosis and a genetic change that alters the immune system in the brain. Researchers found people with psychosis associated with bipolar disorder had decreased expression of GRK3. This led to an increased amount of kynurenic acid in the brain.
Cholinesterase inhibitors such as galantamine, donepezil, and rivastigmine, appear to generate persistent cognitive benefits, and increased longevity for up to five years in Alzheimer's patients.
A new neuroimaging study reveals brain patterns that differentiate between men and women are less pronounced in non-heterosexual people. The differences occurred primarily in sensory processing areas of the brain, in particular areas associated with visual processing. Researchers say the brain differences could be linked to a genetic predisposition for same-sex sexual behaviors. The study reveals a neurobiological basis for same-sex attractions.
People with subclinical ADHD symptoms are more vulnerable to the effects of sleep deprivation and showed greater impairment in both attentional regulation and emotional control following sleep loss than those without ADHD.
Researchers have identified two alternative pathways for the development of amyloid pathologies in Alzheimer's disease.
Neural mapping of the enteric nervous system reveals how fetal neurons form during development. The process of neural development in the ENT follows different principal to the development of neurons in the brain.
p11, a protein implicated in serotonin function, affects the initial release of cortisol in mice by modulating the activity of specific neurons in the hypothalamus. Previous studies found people with depression lave lower levels of p11 in their brains. The findings could help in the development of new treatments for depression and stress.
