How is Moro reflex tested?

What is Moro reflex also known as?

The Moro reflex is often called a startle reflex. That’s 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 his or her arms and legs, cries, then pulls the arms and legs back in.

What causes exaggerated startle reflex in adults?

The exaggerated startle reflex in HPX is probably caused by brainstem pathology. This is supported by the concentration of glycine receptors in the brainstem and spinal cord (Rousseau et al., 2008). In addition, symptomatic excessive startling is usually caused by brainstem damage (Bakker et al., 2006).

What type of disorder is associated with an increase in the startle reflex?

Hyperekplexia is a rare hereditary, neurological disorder that may affect infants as newborns (neonatal) or prior to birth (in utero). It may also affect children and adults. Individuals with this disorder have an excessive startle reaction (eye blinking or body spasms) to sudden unexpected noise, movement, or touch.

What is exaggerated startle reflex?

Hyperekplexia is a pathological exaggeration of the physiological startle response [8]. It consists of an exaggerated response to unexpected stimuli, especially sounds. Compared with normal startle, the response is more intense and longer lasting; it can be triggered more easily; and it usually does not habituate.
