Brain Immune System is Key to Recovery from Motor Neuron Degeneration

Researchers engineered mice in which the damage caused by a mutant human TDP-43 protein could be reversed by one type of brain immune cell. TDP-43 is a protein that misfolds and accumulates in the motor areas of the brains of ALS patients. They found that microglia, the first and primary immune response cells in the brain and spinal cord, are essential for dealing with TDP-43-associated neuron death.

What Can Twitter Reveal About People With ADHD? Penn Researchers Provide Answers

In a Twitter-based study, Penn researchers found that people with ADHD tended to post messages related to lack of focus, self-regulation, intention and failure, as well as expressions of mental, physical and emotional exhaustion. They often used words like those in the word cloud above more frequently than the control group and often posted during hours of the day when the majority of people sleep, from midnight to 6 a.m.
