  • Ernst Trömner: beyond the reflex hammer. [Historical Article]
    Neurol Sci. 2019 Jan; 40(1):221-225.Pomblum VJ, Siepmann T
  • Ernst Trömner (1868-1930) was a German neurologist and psychiatrist at the St. Georg Hospital in Hamburg. As clinician and researcher, he contributed to our understanding of various fields within neurology including language and speech disorders, hypnosis and suggestion, sleep physiology and diseases, leukemia with nervous system involvement, gait disorders, metabolic myelopathy, Parkinson's dise…
  • Corneomandibular reflex: Anatomical basis. [Case Reports]
    J Neurosci Rural Pract. 2015 Oct-Dec; 6(4):591-3.Pistacchi M, Gioulis M, … Marsala SZ
  • Corneomandibular reflex is a pathological phenomenon evident in cases of severe brainstem damage. It is considered to be a pathological exteroceptive reflex, associated with precentro bulbar tract lesions. The sign is useful in distinguishing central neurological injuries to metabolic disorders in acutely comatose patients, localizing lesions to the upper brainstem area, determining the depth of …
  • Primitive reflexes in amyotrophic lateral sclerosis: prevalence and correlates. [Journal Article]
    J Neurol. 2014 Jun; 261(6):1196-202.Tremolizzo L, Susani E, … Appollonio I
  • Identifying frontal impairment in ALS is an important goal albeit disease-dedicated tools are still scarce. For this reason, we decided to consider primitive reflexes (PRs), variably regarded as correlates of frontal release and/or of upper motor neuron (UMN) impairment, often in the setting of dementias. Specifically, the aims of this work consisted in assessing the exact prevalence of the combi…
  • Brainstem reflexes: electrodiagnostic techniques, physiology, normative data, and clinical applications. [Review]
    Muscle Nerve. 2002 Jul; 26(1):14-30.Aramideh M, Ongerboer de Visser BW
  • An overview is provided on the physiological aspects of the brainstem reflexes as they can be examined by use of clinically applicable neurophysiological tests. Brainstem reflex studies provide important information about the afferent and efferent pathways and are excellent physiological tools for the assessment of cranial nerve nuclei and the functional integrity of suprasegmental structures. In…
  • Corneomandibular reflex in ALS. [Journal Article]
    Neurology. 1999 May 12; 52(8):1699-701.Okuda B, Kodama N, … Sugita M
  • To clarify the diagnostic value of corneomandibular reflex (CMR) in ALS, the authors examined the prevalence of CMR and other pathologic reflexes in 42 patients with ALS and 110 patients with stroke. A total of 30 of 42 ALS patients had positive CMR. Compared with the patients with hemiparesis or pseudobulbar palsy after stroke, the ALS patients showed a significantly higher frequency of CMR but …
  • Spontaneous palpebromandibular synkinesia: a localizing clinical sign. [Case Reports]
    Ann Neurol. 1994 Feb; 35(2):222-8.Pullicino PM, Jacobs L, … Miller LL
  • In the classical corneomandibular reflex (CMR), corneal stimulation elicits a bilateral eyelid blink and a brisk anterolateral jaw movement. We here describe 14 patients with a spontaneous palpebromandibular (eyelid-jaw) synkinesia (SPMS) in whom jaw movements, similar to those in CMR, regularly accompanied spontaneous eye blinks without an external corneal stimulus. Eleven of the patients with S…
  • Release signs in Parkinson's disease with and without dementia. [Journal Article]
    J Neural Transm Park Dis Dement Sect. 1992; 4(3):207-12.Marterer-Travniczek A, Danielczyk W, … Fischer P
  • Release signs have been described in both age-associated diseases and in the healthy elderly. We investigated the palmomental, snout, grasp, corneomandibular and glabellar reflexes in demented and non-demented Parkinson-patients compared to Alzheimer's disease and age-matched controls. The palmomental reflex and a persisting glabellar reflex were linked to parkinsonism irrespective of dementia an…
  • Influence of dopamine and disease severity on primitive reflexes in Parkinson's disease. [Journal Article]
    Eur Neurol. 1989; 29(3):141-4.Huber SJ, Paulson GW
  • Several primitive reflexes are common in patients with Parkinson's disease (PD), but can also be noted in patients who have diffuse cerebral degeneration. The glabellar response is present in virtually all patients with PD and this reflex has been of theoretical interest in PD. It has been suggested that the glabellar response is related to inhibition via dopamine pathways. We examined changes in…
  • The diagnostic value of three common primitive reflexes. [Journal Article]
    Eur Neurol. 1984; 23(1):17-21.Isakov E, Sazbon L, … Najenson T
  • Systematic attempts were made to elicit the snout, palmomental and corneomandibular reflexes in 50 young patients with prolonged traumatic coma, 50 elderly hemiplegics soon after their first cerebrovascular accident and in 100 normal age-matched controls. None was found significantly more frequently alone in brain-damaged patients than in age-matched controls. Only combinations of two or three re…
  • Primitive reflexes in Down's syndrome. [Journal Article]
    J Ment Defic Res. 1983 Mar; 27 (Pt 1):39-44.Sand T, Mellgren SI, Hestnes A
  • The clinical value and prevalences of three primitive reflexes, i.e. the palmomental, the snout, and the corneomandibular, were examined in 30 institutionalized patients with Down's syndrome and the results were compared with those in a control group. The prevalence of palmomental reflex was clearly higher, i.e. 47% (31,63) in DS as compared to 7% (2,16) in controls (confidence limits, P = 0.9, i…
  • Clinical significance of the corneomandibular reflex. [Journal Article]
    Arch Neurol. 1982 Sep; 39(9):578-80.Guberman A
  • Lesion site, etiology, and clinical signs were analyzed in 50 cases of unilateral or bilateral corneomandibular reflex. The reflex was seen most commonly in acutely ill patients with a reduced level of consciousness and elevated intracranial pressure (ICP). Large cerebral hemispheric lesions with secondary brainstem pressure, intrinsic lesions of the upper brain-stem or diencephalon, diffuse or m…
  • Three primitive reflexes in parkinsonism patients. [Journal Article]
    Neurology. 1980 Feb; 30(2):189-92.Gossman MD, Jacobs L
  • One or more of three rimitive reflexes (palmomental snout, and corneomandibular) was elicited in 63.8% of 58 parkinsonism patients in the sixth through ninth decades of life. The incidences of the palmomental and snout reflexes in parkinsonism patients did not differ significantly from the incidences in 60 normal subjects of similar ages. The incidence of the corneomandibular reflex in parkinsoni…
  • Three primitive reflexes in normal adults. [Journal Article]
    Neurology. 1980 Feb; 30(2):184-8.Jacobs L, Gossman MD
  • One or more of three primitive reflexes (palmomental, snout, and corneomandible) was elicited in 50.5% of 105 normal subjects in the third through the ninth decades of life. The reflexes appeared in a patterned fashion with advancing age. The palmomental reflex appeared earliest and was the most frequent reflex elicited at all ages. The snout and corneomandibular reflexes appeared at later ages a…
  • Recovery of communicative functions after prolonged traumatic coma. [Journal Article]
    Scand J Rehabil Med. 1978; 10(1):15-21.Najenson T, Sazbon L, … Schechter I
  • Fifteen patients with prolonged coma after craniocerebral injury were observed for a year or more, and their communicative functions were evaluated. Nine of them showed a considerable degree of recovery, while 6 remained in a vegative state. Of the 9 with recovery, 6 showed complete recovery of semantic functions, while 3 remained with aphasic deficits. Eight out of these 9 remained dysarthric. C…
  • The corneomandibular reflex. [Journal Article]
    J Neurol Neurosurg Psychiatry. 1971 Jun; 34(3):236-42.Gordon RM, Bender MB
  • Seven patients are presented in whom a prominent corneomandibular reflex was observed. These patients all had severe cerebral and/or brain-stem disease with altered states of consciousness. Two additional patients with less prominent and inconsistent corneomandibular reflexes were seen; one had bulbar amyotrophic lateral sclerosis and one had no evidence of brain disease. The corneomandibular ref…
