- Abstract
- "Background : The primitive reflexes such as palmomental, glabella, snout, nuchocephalic reflexes may appear in a
variety of diseases of the central nervous system. In this study, we investigated the frequencies of these primitive reflex -es
in the healthy elderly Korean population that have never been studied before. Methods : Randomly selected 103 vol-unteers
aged older than 60 years were examined by neurologists with a systemic neurological examination which
included primitive reflexes and by radiologists with neuroimaging. Seven subjects were excluded from the study due to
abnormal findings in the MRI of one subject and unusual neurological signs in 6 subjects. Results : The overall mean
age of the subjects was 66.5 years. One or more of the primitive reflexes were seen in 26 (24.9%) subjects. Eighteen
(17.2%) subjects showed the palmomental reflex; eleven (10.5%) subjects showed the glabella reflex; five (4.8%) sub-jects
showed the snout reflex; and one (1.0%) subject showed the nuchocephalic reflex. One subject had palmomental,
glabella as well as snout reflexes, and five subjects had two primitive reflexes at the same time. Conclusions : Despite
the normal findings from the neurological examinations and neuroimaging, 24.9% of healthy aged people had one or
more primitive reflexes. The presence of these primitive reflexes as an isolated phenomenon may not imply brain
lesions. J Korean Neurol Assoc 19(4):380~383, 2001 Key Words : Primitive reflexes, Normal subjects"
