New gene may drive earliest brain changes in Alzheimer’s

Genetic analysis of almost 4,300 samples reveals a link between the appearance of amyloid deposits, APOE, and a novel gene called RBFOX1. Lower levels of RBFOX1 in the brain appear to be associated with increased amyloid and global cognitive decline over a person's lifetime. Read More

The molecular mechanisms of depression

Study reveals how the brain's opioid system is linked to mood changes associated with depression and anxiety. Neuroimaging revealed, in those with depression, there is a decreased number of opioid receptors in specific areas of the brain. Read More

How ketamine combats depression

Ketamine increases the number of serotonin 1B receptors. Ketamine binds to serotonin 1B receptors, reducing the release of serotonin and increasing the release of dopamine. Read More

Study finds evidence for reduced brain connections in schizophrenia

Neuroimaging study reveals decreased levels of the SV2A protein in synapses in patients with schizophrenia. The decrease in the protein could underlie the cognitive difficulties experienced by those with schizophrenia and provide new targets for treatment. Read More

Promising steps towards hope for a treatment for schizophrenia

Mu-opioid receptor (MOR) levels are significantly reduced in the striatum in those with schizophrenia. A lack of MOR system stimulation contributes to negative feelings, such as a lack of motivation and anhedonia, associated with the condition. Increasing MOR levels could help to reduce some of the symptoms of schizophrenia. Read More

Alzheimer’s memory loss reversed by new head device using electromagnetic waves

A new, non-invasive brain stimulation treatment shows promise in enhancing memories and cognitive function in those with Alzheimer's disease. Transcranial electromagnetic treatment (TEMT) increases functional connectivity within the cingulate cortex. TEMT is also able to penetrate the brain to break up amyloid-beta and tau deposits, slowing the progression of Alzheimer's disease. Read More
