The neurotransmitter serotonin has an essential role in behavior and cognition. It has been seen as having a big part of common neuropsychiatric diseases such as major depressive disorder and anxiety disorders. This study added to the increasing evidence for a direct interaction between serotonin and brain-derived neurotrophic factor. There continues to be insufficient data for the interaction of serotonin and BDNF.
Millions of concussions are sustained each year by children, adolescents, and adults while playing sports. These mild traumatic brain injuries are complex due to multiple neurologic symptoms like cognitive and motor deficits.
Researchers at the University of Copenhagen have found autoreactive cells in people who suffer from narcolepsy. This is an important breakthrough that proves narcolepsy is indeed an autoimmune disease. For years doctors have suspected that narcolepsy had some connection between the area that controls wakefulness and the autoimmune system. They have found cytotoxic CD8 T-cells in the blood of narcoleptics. At this point, they know that the immune cells of the patient's body sees normal cells in the body as invaders and attacks them. This results in them having narcolepsy. Researchers have found a combination of genetics, autoimmune cells, and some type of trigger (like a virus) that then leads to this disease.
Interstitial Lung Disease (ILD) has many lung disorders that fall under that term. One of them Idiopathic Pulmonary Fibrosis (IPF), is the most common of these disorders. Asbestosis is diffuse pulmonary fibrosis resulting in a slowly progressing disease that can take from 15 to 40 years after exposure to be encountered physical symptoms. And while in most developing countries it has been banned, the exposure-related diagnoses are still being cared for.
Vaccinations against many childhood diseases are much needed yet often not given. Antivaccination people are creating pockets of unvaccinated children who then spread the most contagious of childhood diseases, measles, to people who are unable to receive vaccinations. In addition, the recent influx of illegal immigrants creates a large drain on health care systems.
Duchenne muscular dystrophy is an inherited neuromuscular disorder primarily occurring in boys and caused by mutations in the dystrophin gene.
