Primitive reflexes are reflex actions originating in the central nervous system that are exhibited by normal infants, but not neurologically intact adults, in response to particular stimuli. These reflexes are suppressed by the development of the frontal lobes as a child transitions normally into child development . [ 1 ]
The symmetrical tonic neck reflex (STNR) is a primitive reflex that normally emerges during the first month of an infant's life and is diminished by the age of 9–10 months. [1] It is a bridging or transitional brainstem reflex that is an important developmental stage and is necessary for a baby to transition from lying on the floor to ...
The asymmetrical tonic neck reflex (ATNR) is a primitive reflex found in newborn humans that normally vanishes around 6 months of age. It is also known as the bow and arrow or "fencing reflex" because of the characteristic position of the infant's arms and head, which resembles that of a fencer. When the face is turned to one side, the arm and ...
Knee jerk or patellar reflex — a kick caused by striking the patellar tendon with a tendon hammer just below the patella, stimulating the L4 and L3 reflex arcs. Moro reflex, a primitive reflex— only in all infants up to 4 or 5 months of age: a sudden symmetric spreading of the arms, then unspreading and crying, caused by an unexpected loud ...
A survey conducted by the Centers for Disease Control and Prevention in 2011–2012 found 11% of children between the ages of 4 and 17 were reported to have ever received a health care provider diagnosis of ADHD at some point (15% of boys and 7% of girls), [182] a 16% increase since 2007 and a 41% increase over the last decade. [183]
The Dyslexia Screening Test identified some of the remaining children as 'at risk,' but the majority of children did not have severe difficulties. A follow-up to this study was published in Dyslexia in 2006, and the authors report significant improvements in writing, reading, and comprehension, as well as ADHD attention skills, after re ...
The tonic labyrinthine reflex (TLR) is a primitive reflex found in newborn humans. With this reflex, tilting the head back (extension) while lying on the stomach causes the back to stiffen and even arch backwards, the legs to straighten, stiffen, and push together, the toes to point, the arms to straighten (not bend at the elbows and wrists, and the hands to become fisted or the fingers to curl).
The Moro reflex may be observed in incomplete form in premature birth after the 25th week of gestation, and is usually present in complete form by week 30 (third trimester). [1] Absence or asymmetry of either abduction or adduction by 2 to 3 months age can be regarded as abnormal, as can persistence of the reflex in infants older than 6 months ...
