How the eyes might be windows to the risk of Alzheimer’s disease

Adults with mild cognitive impairment (MCI), a precursor to Alzheimer's disease, have greater pupil dilation when taking cognitive tests than their cognitively normal peers. Task-evoked pupillary response may be a cost-effective, and low invasive screening test for those at genetic risk for Alzheimer's before the symptoms of the disease take hold. ... Read More...

Genes associated with left-handedness linked with shape of the brain’s language regions

Four genetic regions have been identified as playing a role in left-handedness. Three of the four genes were associated with proteins involved in brain development and structure. Neuroimaging revealed those who were left-handed had increased functional connectivity between left and right language networks. Researchers also found correlations between the genetic regions associated with left-handedness and slightly reduced Parkinson's risk, but a slightly increased risk for schizophrenia.... Read More...

The neurobiological mechanisms behind schizophrenia may depend on gender

Schizophrenia is linked to alterations in pathways associated with glycosaminoglycan, neurotransmitter metabolism, and GABAergic synapses. A large percentage of genes related to schizophrenia are expressed differently between males and females. The results imply the mechanisms involved in schizophrenia development differ, at least slightly, between males and females.... Read More...
