Unable to elicit moro response

Introduction

Introduction Moro reflex, this is a full-body movement that is most clearly seen when the baby is lying on his back. Sudden stimuli, such as the sudden appearance of gunshots or other louder sounds, or the placement of babies in small beds, can cause shocking reflections. In the case of a startle reflex, the baby's arms are straight, the fingers are open, the back is stretched or bent, the head is tilted back, the legs are straight, and the arms are held together.

Cause

Cause

This reflex is a remnant of human evolution from the primate lineage, which shows the ability of young animals to reach out to their mothers in an emergency. 1 more than 4 months still: possible neuropathy, 2 more than 6 months still: there must be neuropathy, 3 upper limb asymmetry: half-body palsy, brachial plexus injury, clavicle or tibia fracture, 4 lower limb reaction disappeared: The spinal cord injury and congenital hip dislocation disappeared for 3-4 months.

Diagnosis

Differential diagnosis

Moro is slow to respond: it's a full-body action that looks best when the baby is lying on his back. Sudden stimuli, such as the sudden appearance of gunshots or other louder sounds, or the placement of babies in small beds, can cause shocking reflections. In the case of a startle reflex, the baby's arms are straight, the fingers are open, the back is stretched or bent, the head is tilted back, the legs are straight, and the arms are held together. 1 more than 4 months still: possible neuropathy, 2 more than 6 months still: there must be neuropathy, 3 upper limb asymmetry: half-body palsy, brachial plexus injury, clavicle or tibia fracture, 4 lower limb reaction disappeared: The spinal cord injury and congenital hip dislocation disappeared for 3-4 months.

Unresponsive: It is not possible to respond appropriately to stimuli as normal people, or to respond slowly.

Excessive startle response: excessive mood, mental allergy, and easy to cause a shocking reaction due to accidental stimulation (such as sudden closing of the door). Delayed stress disorder: Symptoms appear within 6 months, and the traumatic experience repeats repeatedly. If you can't help but recall the experience of being hit, the nightmare of traumatic content reappears, and the sustained alertness increases, such as difficulty falling asleep or awakening. Excessively shocked reaction, alienated from people, not friendly, anxious.

Overreaction to stimuli such as hearing, sight, and touch: one of the manifestations of Crabbe disease. Crabbe disease was first reported by the Danish pediatrician Krabbe in 1916. It is therefore called Krabbe disease. According to its clinical features, it is also called familial diffuse sclerosis. It is an autosomal recessive metabolic disease with a mutation gene at 14p. There was no normal startle reflex after being scared.
