They are often repetitive in nature and typically involve twitching of the corner of the mouth, grimacing, twitching of the corner of the eye, blinking, or general movements with the arms, shoulders, or hands. Some nervous tics are caused by brain damage or damage to the nervous system, ...
aOur results confirm prior studies suggesting that tics are caused by alterations in prefrontal areas, thalamus and putamen, while changes in the cingulate gyrus seem to reflect secondary compensatory mechanisms. Due to the study design, influences from comorbidities, gender, medication and age can ...

Tourette Syndrome (TS) refers to a neurodevelopmental disorder characterized by motor and vocal tics that begin in childhood [1]. Tics are movements that are automatically made, often connected to an urge – a specific sensory feeling – preceding the tic. Patients report a temporary relief of ...
The functional neurological symptoms caused by FND are real, physical symptoms, but they generally cannot be explained by any changes in brain structure, such as a traumatic brain injury. In addition, there is no known cause of the condition, and each person’s symptoms can differ, so treatmen...
Tics are similar to stereotypies, but the muscle jerks that characterize tics are normally preceded by a mental urge, whereas stereotypies are not. People who have AttentionDeficitandHyperactivityDisorder (ADHD) can also express unusual movements, but these are not stereotypies, but rather seem ...
Gilles de la Tourette (ZHEEL de la too-RETT) syndrome is a neurological disorder that causes a person to make sudden movements or sounds, which are called tics. Many scientists think Tourette syndrome is caused by a chemical imbalance in the brain. ...
Personally I'm fully aware of the death toll by insects. I don't doubt that part at all. I am not sure what happens if. A. No one is killed by bite infection where does that place us in population growth terms. B. Are they sure that killing off tics will not damage ecosystems we...
Obsessive compulsive disorder (OCD) is a mental health condition characterized by a cycle of uncontrollable, chronic thoughts (obsessions) and repetitive behaviors (compulsions) that severely interfere with daily functioning. Neuroscientists believe that these symptoms are caused by hyperactivity in specific...
Cell-culture systems have made a crucial contribu- tion to the diagnosis of infectious diseases that are caused by viruses and intracellular bacteria. Such sys- tems have not only made the direct isolation and identi- fication of microorganisms possible, but have also enabled the production of ...
