Diagnostic yield of the Palmomental Reflex in patients with suspected frontal lesion
Journal of the Neurological Sciences, 2015Co-Authors: Diana Ladino, Sandra Isaza, Jorge Delgado, Simon Rascovsky, Carlos Santiago Uribe, Santiago Acebedo, William Cornejo, Lizbeth Hernández-ronquillo, Jose F. Tellez-zentenoAbstract:Abstract Background The purpose of this study was to determine the diagnostic value of the Palmomental Reflex in order to identify frontal lesions in neurological outpatients. Methods Two hundred twenty-six neurological patients with suspected intracranial lesion with an indication for magnetic resonance imaging (MRI) were included. All patients underwent the same MRI protocol. The Reflex was elicited by trained and standardized nurses, and was evaluated by two neurologists. The evaluation was blind and independent. The test's accuracy was calculated. The Kappa coefficient was used to calculate the interobserver and intra-observer reliability. Results The interobserver reliability between neurologists was 0.53 with 93% of agreement (p Conclusion The Palmomental Reflex is associated with frontal structural lesions but the sensitivity is low, indicating a high percentage of frontal lesions with a negative Reflex. When the test is used on its own, it is insufficient to detect frontal damage.

The Kappa coefficient was used to calculate the interobserver and intra-observer reliability. The interobserver reliability between neurologists was 0.53 with 93% of agreement (p<0.001). The diagnostic accuracy measures were as follow: sensitivity of 19%, specificity of 93%, positive predictive value of 30%, negative predictive value of 88%, positive likelihood ratio of 2.7 and negative likelihood ratio of 0.87. The area under the curve was 0.56.

Indian J. Psychiat., 1994,36(3), 145-146. TRANSIENT RELEASE ReflexES IN CATATONIC SCHIZOPHRENIA
2013Co-Authors: Saji S. Damodaran, Vinod K. SinhaAbstract:This case report describes the presence of grasp Reflex and Palmomental Reflex as a state dependant phenomenon in a 23 year old patient with catatonic schizophrenia. A transitory disturbance of frontal lobe function is proposed as the probable mechanism. The need to study the release Reflexes as an effort to delineate a neurological "sub group " of schizophrenia is suggested Key words: transient release Reflex, frontal lobe, catatonia
