Frontal release signs are primitive reflexes traditionally held to be a sign of disorders that affect the frontal lobes. The appearance of such signs reflects the area of brain dysfunction rather than a specific disorder which may be diffuse, such as a dementia, or localised, such as a tumor.
Primitive reflexes are mediated by extrapyramidal functions, many of which are already present at birth. They are lost as the pyramidal tracts gain functionality with progressive myelination. They may reappear in adults or children with loss of function of the pyramidal system due to a variety of reasons.
The thenar eminence is stroked briskly with a thin stick, from proximal (edge of wrist) to distal (base of thumb) using moderate pressure. A positive response is considered if there is a single visible twitch of the ipsilateral mentalis muscle (chin muscle on the same side as the hand tested).
Symptoms may include vision changes (seeing spots, blurriness, light sensitivity), a headache that won’t go away, shortness of breath, pain in your upper belly, nausea and/or vomiting, decreased ...
Frontal release signs are seen in disorders that affect the frontal lobes, such as dementias, metabolic encephalopathies, closed head injuries, and hydrocephalus. All of these disorders produce diffuse cerebral damage, usually involving many areas and systems in addition to the frontal lobes and pyramidal system , so the frontal release signs ...
The glabellar reflex, also known as the "glabellar tap sign", is a primitive reflex elicited by repetitive tapping of the glabella — the smooth part of the forehead above the nose and between the eyebrows. [1]

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. [3]
