The effects of intoxication, such as slurred speech and poor coordination, are a result of the breakdown of alcohol products in the brain and not the liver.
While cannabis users reported more psychotic experiences than non-users generally, the effect was more pronounced in those with a genetic risk factor for schizophrenia.
Olfactory imprinting in infant mice has a direct impact on their social behaviors as adults.
Children and young adults with a specific variant of the PTPRD gene are at greater risk of developing obsessive-compulsive disorder.
An increase in bad gum bacteria and a decrease in good bacteria is associated with amyloid-beta in cerebral spinal fluid samples of older adults. The findings add to the growing body of evidence linking periodontal disease to the development of Alzheim…
Study of gar fish reveals the modern eye-brain connection may have evolved much earlier than previously believed.
Study reveals aluminum is co-located with the tau protein in people with familial Alzheimer’s disease.
Genetics may help explain why women are at higher risk for developing chronic pain disorders than men. The study also sheds light on the role the central nervous system plays in the development of chronic pain.
Mutations in the autism-related Dyrk1a gene lead to brain undergrowth in mice. Researchers say an existing drug appears to reverse the damage.
A new blood test can distinguish the severity of a person’s depression and their risk for developing severe depression at a later point. The test can also determine if a person is at risk for developing bipolar disorder. Researchers say the blood test …
Study reveals the role the mouse gene Ophn1 plays in helpless behaviors and identified three methods in which to reverse the effect.
miRNA29 is a key cellular switch in controlling late-stage brain development. Deleting miRNA29 in mice resulted in problems associated with a range of neurodevelopmental problems, including autism and epilepsy.
DNA markers in cells of patients with major depressive disorder appear to be two years older than markers in cells of people without the mental health disorder.
Researchers have identified 76 overlapping genetic locations that determine the shapes of our faces and our brains. The genetic signals that influence face and brain shape are enriched by regions of the genome that regulate gene activity during embryog…
Cysteine leukotriene receptor 2 appears to be a key player in chronic itch, a new study reports.
The S198P mutation causes APP to fold more quickly, allowing amyloid-beta peptides to produce from mature APP at a more rapid rate than from APP that does not contain the genetic mutation. The findings shed new light on genetic mutations associated wit…
A new whole-genome sequencing study has revealed thirteen novel genes associated with Alzheimer’s disease. Researchers also found a new link between Alzheimer’s and synaptic function.
Disruptions in the Atk protein can lead to brain changes that are characteristic of bipolar disorder.
Exercise helped to reduce cognitive decline two years later in Parkinson’s patients with the APOE e4 gene variant.
Two existing medications show promise in the treatment of the deadly childhood cancer, neuroblastoma. Phenformin and AZD3965 exploit the metabolic hunger of the disease to kill cancer cells without inflicting excessive damage to healthy tissue.
