Electrophysiological assessments of primitive Reflexes in stroke patients
2009Co-Authors: Chang Chein-weiAbstract:Objectives: To evaluate the primitive Reflexes by OBJECTIVE: To evaluate the primitive Reflexes by electrophysiological assessments and their correlation with electrophysiological assessments and their correlation with the cognitive and physical functioning of stroke patients. the cognitive and physical functioning of stroke patients. Methods: Electrophysiological studies of primitive Reflexes METHODS: Electrophysiological studies of primitive Reflexes including jaw jerk, snout Reflex, Glabellar Reflex, and including jaw jerk, snout Reflex, Glabellar Reflex, and corneomandibular Reflexes were performed in 38 stroke corneomandibular Reflexes were performed in 38 stroke patients and 26 normal controls. Cognitive function of patients and 26 normal controls. Cognitive function of patients was assessed by Modified Mini-Mental State (3MS) patients was assessed by Modified Mini-Mental State (3MS) Examination and logical memory test. The Chinese Functional Examination and logical memory test. The Chinese Functional Independence Scale (CFIS) was used to evaluate the physical Independence Scale (CFIS) was used to evaluate the physical functioning and social domains of stroke patients. Results: functioning and social domains of stroke patients. RESULTS: The presence rate of primitive Reflexes was higher in stroke The presence rate of primitive Reflexes was higher in stroke patients than in normal controls. Wave amplitude of snout patients than in normal controls. Wave amplitude of snout and corneomandibular Reflexes obtained from stroke patients and corneomandibular Reflexes obtained from stroke patients was greater than those from controls. No definite difference was greater than those from controls. No definite difference in Reflex conduction latencies was observed between the two in Reflex conduction latencies was observed between the two groups. A regression relationship was noted between the groups. A regression relationship was noted between the wave amplitude of snout Reflexes and the 3MS and CFIS scores wave amplitude of snout Reflexes and the 3MS and CFIS scores of stroke patients. Conclusion: Primitive Reflexes can be of stroke patients. CONCLUSION: Primitive Reflexes can be measured by electrophysiological assessments. The results measured by electrophysiological assessments. The results may serve as an objective and useful parameter in evaluation may serve as an objective and useful parameter in evaluation of cognition and physical functioning of stroke patients. of cognition and physical functioning of stroke patients

Reversal of the Glabellar Reflex in Parkinsonism by L-dopa
2016Co-Authors: Harold L. Klawans, James A. GoodwiAbstract:The Glabellar Reflex was first described in 1896 by Overend. Since then many names have been applied to this phenomenon, which is characterized by blinking of the eyes in response to various stimuli applied to the face and cranium. Wartenberg (1945) in a review of the subject described the Reflex as myotatic in nature and pro-fessed that the best way to elicit it consisted of grasping the outer canthus of the eye with thumb and forefinger and then applying a slight blow to the examiner's fingers with a Reflex hammer. The stimulus from which the Reflex gains its name, how-ever, is a light tap to the glabella. In normal persons, when the tap frequency is held constant, the blinking stops after the first fe

Primitive Reflexes and cognitive function Reflexos primitivos e função cognitiva
Academia Brasileira de Neurologia (ABNEURO), 2005Co-Authors: Alfredo Damasceno, Am Delicio, Daniel F.c. Mazo, João F.d. Zullo, Patricia Scherer, Benito P. DamascenoAbstract:BACKGROUND: Data on the prevalence of primitive Reflexes (PR) in adulthood, their pathological significance and relationship to age and cognition are controversial. OBJECTIVE: To study the relationship between PR and cognition in 30 patients with probable Alzheimer's disease (AD) and 154 control subjects. METHOD: Diagnosis of probable AD was based on DSM-IV, NINCDS-ADRDA, and CAMDEX criteria. Primitive Reflexes were quantified from zero (absent) to 1 (mild) or 2 (markedly present). The Cognitive Abilities Screening Instrument - Short Form (CASI-S) was used to evaluate registration, temporal orientation, verbal fluency and recall. A drawing test was added. RESULTS: Most frequent PR among demented and controls were suck (77% and 62%, respectively) and snout (60% and 27%), followed by Glabellar (30% and 19%), paratonia (37% and 5%), and palmomental (23% and 5%). None of controls had more than three PR. Frequency of PR tended to increase with age and cognitive deterioration. Grasp and Babinski responses were found only in dementia patients. Primitive Reflexes were not correlated with each other, except snout with suck, and snout with Glabellar Reflex. CONCLUSION: The finding of grasp and Babinski sign, or the presence of more than three primitive signs, particularly the combination of paratonia, snout, suck, and palmomental Reflexes strongly suggests brain dysfunction, especially when these signs are marked and accompanied by deficits in orientation, recall, verbal fluency, and constructional praxis.CONTEXTO: A prevalência e significado patológico dos Reflexos primitivos (RP) no adulto, bem como sua relação com a idade e a cognição, são questões controversas. OBJETIVO: Estudar a relação entre RP e cognição em 30 pacientes com doença de Alzheimer (DA) e 154 sujeitos controles normais. MÉTODO: O diagnóstico de DA baseou-se nos critérios DSM-IV, NINCDS-ADRDA e CAMDEX. Os RP foram quantificados de 0 (ausente) a 1 (leve) ou 2 (acentuado). CASI-S (Cognitive Abilities Screening Instrument -Short Form) foi usado para avaliar o registro, orientação temporal, fluência verbal e evocação. Um teste de cópia de pentágonos foi acrescentado. RESULTADOS: Os RP mais frequentes nos pacientes e controles foram o de sucção (77% e 62%, respectivamente) e "snout" (60% e 27%), seguidos do glabelar (30% e 19%), paratonia (37% e 5%) e palmomentoniano (23% e 5%). Nenhum sujeito controle teve mais que três RP. A frequência dos RP tendeu a aumentar com a idade e a deterioração cognitiva. O Reflexo de preensão e o sinal de Babinski foram encontrados apenas nos pacientes com DA. Os RP não se correlacionaram uns com os outros, exceto o Reflexo "snout" com o de sucção e com o glabelar. CONCLUSÃO: O achado de Reflexo de preensão e sinal de Babinski, ou a presença de mais de três sinais primitivos, particularmente a combinação de paratonia e Reflexos "snout", sucção e palmomentoniano, são sugestivos de disfunção cerebral, especialmente quando esses sinais são acentuados e acompanhados de déficits de orientação, evocação, fluência verbal e praxia construcional
