Blood biomarkers for detecting brain injury in COVID-19 patients

COVID-19 can directly cause neurologic symptoms and long-term neurological disease. Elevations of blood biomarkers indicative of brain injury have been reported in the blood and cerebrospinal fluid of COVID-19 patients. Clinical ...

Emotion detection in Parkinson's disease

Parkinson's disease is a neurodegenerative disorder that leads to significant disturbances to motor control resulting in involuntary tremor, shuffling gait, muscular rigidity, and other problems. The disease also leads to ...

Detecting Alzheimer's disease before symptoms arise

Both of Andrew Kiselica's grandfathers developed dementia when he was in graduate school. As Kiselica was going through neuropsychology training in graduate school, he saw his mother's father become unable to walk or speak ...

Q&A: Dissecting movement disorders through the eyes of a fly

Every time we move, electrical impulses are channeled along neuronal highways, jumping from nerve cell to nerve cell until they reach a muscle, causing it to contract. Because muscle movement depends on neuronal function, ...

Probe detects the destruction of defective mitochondria

A versatile probe that can detect with pinpoint accuracy the programmed destruction of defective mitochondria—the powerhouses of cells—has been developed by RIKEN researchers. They used it to show that damaged mitochondria ...

Neurodegenerative disease

Neurodegenerative disease (Greek νέυρο-, néuro-, "nerval" and Latin dēgenerāre, "to decline" or "to worsen") is a condition in which cells of the brain and spinal cord are lost. The brain and spinal cord are composed of neurons that do different functions such as controlling movements, processing sensory information, and making decisions. Cells of the brain and spinal cord are not readily regenerated en masse, so excessive damage can be devastating. Neurodegenerative diseases result from deterioration of neurons or their myelin sheath which over time will lead to dysfunction and disabilities resulting from this.

Some sources limit the term "degenerative" to conditions primarily affecting gray matter that are not associated with a obvious inciting event.
