Sniffing Out the Mechanism Behind Parkinson’s Smell Loss

Up to 90% of patients report experiencing a diminished sense of smell, even prior to the onset of other symptoms of Parkinson's disease. A new study reveals the mechanism behind smell loss associated with Parkinson's, reporting mouse models with olfactory impairments had severe pathology in projection neurons of the olfactory pathway. The mice also had reduced neurogenesis in the olfactory bulb.

Brain’s ‘Wakeful Rest’ Network May Be Key to Alzheimer’s Risk

In women, parts of the default mode network responsible for memory retrieval and recollection, and spatial cognition were more likely to be connected to the overall DMN network. The patterns of connectivity correlated with brain structures associated with short-term memory problems resembled alterations seen in preclinical Alzheimer's disease.

3D Organoid Models Show Brain Mechanisms of Tourette Syndrome

Using induced pluripotent stem cells derived from skin cells of people with Tourette syndrome, researchers create 3D brain organoid models of the basal ganglia, an area of the brain previously implicated in TS. The model reveals potential pathologies behind the disorder and could help fashion new therapies to treat TS.

Can Neuroimaging Reveal the Roots of Psychiatric Disorders? Not Just Yet

While neuroimaging holds great potential in helping researchers link specific patterns of brain activity to mental health disorders, a new study finds there is still a way to go to effectively link neuroimaging results to specific mental health disorders.

Inflammation May Explain Antidepressants’ Link to Preterm Birth

The common antidepressant Prozac (fluoxetine) provokes an inflammatory response in the amniotic sac. The findings may reveal the underlying factor of why women who take SSRI antidepressants are at higher risk of preterm birth.

Swelling Along Brain’s Axons May Be True Culprit in Alzheimer’s Disease

The formation of plaques can cause the accumulation of spheroid-shaped swellings along axons near the amyloid plaque deposits. The swellings are caused by lysosomes, which digest cellular waste. As the swelling enlarges, it can block the transmission of signals from one area of the brain to another.
