Auditory hallucinations rooted in aberrant brain connectivity

Auditory hallucinations, a common feature of psychosis and schizophrenia, may be the result of increased connectivity between sensory and language processing areas in the brain. Read More

Protein in mitochondria appears to regulate health and longevity

Humanin, a peptide encoded in mitochondria, appears to have a beneficial impact on both health and longevity in both humans and animals. Higher levels of humanin in the body are associated with longer life spans and a reduced risk of neurodegenerative disorders, like Alzheimer's disease. Read More

Unexpected mental illnesses found in a spectrum of a rare genetic disorder

Fragile X syndrome patients with prematuration had a much earlier onset of neurological problems, including earlier symptoms of neurodegeneration. They also experienced emotional processing problems. Some of the most common emotional processing disorders reported were mood regulation, anxiety, and psychosis. Read More

Genetic malfunction of brain astrocytes triggers migraine

Familial hemiplegic migraine type 2 (FHM2) causes a malfunction of astrocytes in the cingulate cortex. Manipulating astrocytes in the cingulate cortex reversed the disfunction, preventing an increase in migraine-like symptoms in mice carrying the FHM2 defect. Read More

One-time treatment generates new neurons and eliminates Parkinson’s disease

Researchers administered PTB antisense oligonucleotide treatment directly to the midbrain of mice. In the mouse models exposed to the treatment, a small subset of astrocytes converted to neurons, increasing the number of neurons by 30%. Three months after treatment, mice were completely free of Parkinson's disease symptoms and remained in remission for the rest of their lives. Read More

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

Brothers in arms: The brain and its blood vessels

Blood vessels can sense the metabolic state of nearby neurons. An imbalance of fatty acids is sensed by neural blood vessels, stimulating them to mount a stress response by loosening the blood-brain barrier. If the imbalance remains, the leaky blood-brain barrier can induce a disease state. Read More
