What is exaggerated Moro reflex?
An exaggerated Moro reflex can be seen in infants with severe brain damage that occurred in-utero, including microcephaly and hydrancephaly. Exaggeration of the Moro reflex, either due to low threshold or excessive clutching, often occurs in newborns with moderate hypoxic-ischemic encephalopathy.
Is exaggerated Moro reflex normal?
Although the Moro reflex is a good sign in newborn babies, some babies have an overactive or exaggerated Moro reflex that can sometimes interfere with sleep. In very rare cases, a severe Moro reflex may be a sign of hyperekplexia, an inherited neurological condition.
When should I worry about Moro reflex?

If the Moro reflex is lacking on one side of your baby’s body, it can be the result of a broken shoulder or a nerve injury. If the reflex is lacking on both sides, it might suggest brain or spinal cord damage.
What causes exaggerated startle response?
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 is startle disease?
Hyperekplexia (startle disease) is a rare non-epileptic disorder characterised by an exaggerated persistent startle reaction to unexpected auditory, somatosensory and visual stimuli, generalised muscular rigidity, and nocturnal myoclonus.
Can Moro reflex cause seizures?
While the Moro reflex is completely normal, there are some sudden movements that need immediate attention, such as a seizure. There are different types of seizures and can sometimes be hard to recognize.
Why do I jump at the slightest noise?
The main issue with noise anxiety is that it occurs because of a raised anxiety baseline, common with PTSD. Noise jumps the anxiety above the baseline, potentially leading to increased startle reflexes and possibly panic attacks.
Why do sudden noises startle me?
A startle reflex can occur in the body through a combination of actions. A reflex from hearing a sudden loud noise will happen in the primary acoustic startle reflex pathway consisting of three main central synapses, or signals that travel through the brain.
What is Coffin Lowry Syndrome?
Coffin-Lowry syndrome (CLS) is a rare genetic disorder characterized by intellectual disability; abnormalities of the head and facial (craniofacial) area; large, soft hands with short, thin (tapered) fingers; short stature; and/or various skeletal abnormalities.
Why do I always jump at loud noises?
They jump at smaller things, they’re hyperirritable, their brain is irritable, meaning, the same loud noises that don’t bother other people seem to bother them. So loud noises, bright lights, the brain is irritable when it’s hypercaffeinated. And often it’s a little underslept.
What is the Moro reflex?

Why is my Baby Not crying during the Moro reflex?
A baby may or may not cry during the reflex. Some babies have an abnormal Moro reflex that involves only one side of the body, while others may have no Moro reflex.

Can Moro reflex wake a baby up from sound sleep?
However, this can be particularly troublesome during sleep time, as it may wake your baby up from sound sleep. Moro reflex is triggered by any sudden changes in sensual stimulation. There are many such triggers, but the common ones are: 1) A loud noise. 2) A sudden touch.
How do I know if my child has retained the Moro reflex?
If the noise startles them and they flail their arms outward, this is another sign of a retained reflex. If you have tested your child or student for the Moro reflex and are sure they have retained it, your child may continue to show signs of sensitivity to light, sound, clothing and other triggers.
