New Cause of Rare 'Startle Disorder' Found People with startle disease have an exaggerated startle reflex in response to noise and touch, followed by muscle stiffness, which can cause breathing problems and even sudden infant death syndrome (SIDS).iew full size image. We all jump at an unexpected noise or touch, but in some people, this startle response is exaggerated, and can cause falls and even death.

Hyperventilation: Symptoms & Signs All of these symptoms are the result of abnormally low levels of carbon dioxide in the blood caused by overbreathing. The term hyperventilation syndrome (HVS) is sometimes used to describe the effects of hyperventilation observed in an emergency department setting. Many acute (sudden onset) cases of hyperventilation arise from panic, anxiety, and other emotional conditions. Hyperventilation, particularly chronic hyperventilation (that persists over time), can also be due to a range of medical conditions. The opposite of hyperventilation is termed hypoventilation (underventilation). REFERENCE:

Newborn-Reflexes Moro reflex. The Moro reflex is often called a startle reflex because it usually occurs when a baby is startled by a loud sound or movement. In response to the sound, the baby throws back his or her head, extends out the arms and legs, cries, then pulls the arms and legs back in. A baby's own cry can startle him or her and trigger this reflex. This reflex lasts about 5 to 6 months. Tonic neck reflex. When a baby's head is turned to one side, the arm on that side stretches out and the opposite arm bends up at the elbow.

- Eosinophilia–myalgia syndrome (EMS) is an incurable and sometimes fatal flu-like neurological condition linked to the ingestion of the dietary supplement L-tryptophan. The risk of developing EMS increases with larger doses of tryptophan and increasing age.Some research suggests that certain genetic polymorphisms may be related to the development of EMS. The presence of eosinophilia is a core feature of EMS, along with unusually severe myalgia (muscle pain).he first case of Eosinophilia–myalgia syndrome was reported to the Centers for Disease Control and Prevention (CDC) in November 1989, although some cases had occurred as early as 2–3 years before this. In total, more than 1,500 cases of EMS were reported to the CDC, as well as at least 37 EMS-associated deaths.

- Histamine also causes constriction of smooth muscle. If you have asthma, histamine is partially to blame. When irritants are inhaled into the lungs, histamine is released to that area, and the smooth muscles around the bronchi of the lungs contract. This makes breathing difficult and can produce an asthma attack.
