Researchers have found evidence that spontaneous eye blink activity, which reflects activity in the dopaminergic system, explains the connection between fitness and cognitive function. This is the first study to indicate that dopamine has an essential role in linking aerobic fitness and cognition. These findings open the door to new research regarding the mechanisms by which exercise improves brain function, and may lead to novel fitness strategies for enhancing cognition.
Higher blood pressure at night than in daytime may be a risk factor for Alzheimer's disease in older men. This is suggested by a new study from researchers at Uppsala University, now published in the journal Hypertension.
While scientists still don't know what causes Parkinson's disease, new research shows an association between a drug that some men take for an enlarged prostate condition and a reduced risk of developing the illness.
Migraine can cause severe, recurrent, and potentially disabling headaches that typically last from 4–72 hours.
Though tremors are quite common, your mind can quickly go into panic mode. Could this be Parkinson’s disease?
Most cysts, especially cysts in the brain, are congenital. Sometimes, a cyst in the brain can develop as a response to an infection, injury, or cancer.
Researchers have found a novel form of the Alzheimer's protein tau in the fluid surrounding the brain and spinal cord. This form of tau -- known as MTBR tau -- indicates what stage of Alzheimer's a person is in and tracks with tangles of tau protein in the brain.
Many people complain about winter, but it can be a particularly challenging time for those who live with chronic conditions.
Absence seizures, previously known as petit mal seizures, are a type of epilepsy. They occur due to brief periods of abnormal electrical activity in the brain.
A research team has developed a diagnostic tool for the rare neurological disease amyotrophic lateral sclerosis (ALS). The study used the patented immuno-infrared sensor to analyze folding changes of proteins in the cerebrospinal fluid (CSF) of ALS patients after specific binding.
