Abnormal enhancement of polysynaptic brainstem reflexes has been previously reported in patients with spinal cord injury (SCI). We aimed to investigate trigemino-cervical reflex (TCR) in SCI since it may reflect alterations in the connections of trigeminal proprioceptive system and cervical motoneurons. Consecutive 14 patients with SCI and 16 healthy(More)
BACKGROUND AND AIM Orthostatic tremor is a high frequency tremor predominantly on calf muscles during standing. Brainstem is the most probable generator in the pathogenesis since it comprises bilaterally projecting centers regulating stance or tone. We aimed to investigate the functional role of brainstem through the evaluation of acoustic startle response(More)
Juvenile myoclonic epilepsy (JME) is hypothesized to originate from the dysfunction of thalamo-cortical circuit. We aimed to analyze any changes in auditory startle response in JME patients to determine the role of brainstem in JME. The responses of 18 JME patients to auditory simulation were recorded over the unilateral orbicularis oculi, masseter,(More)
Trigemino-cervical reflex (TCR) is elicited by stimulation of face using various modalities. TCR reflects the interaction between trigeminal system and cervical motoneurons. Such a specific interaction is assumed to play role in development of cervical dystonia (CD) through superior colliculus. In this study, we aimed to investigate alterations of the(More)
Rasmussen syndrome is a rare, inflammatory and probably autoimmune disease presenting with epilepsia partialis continua which is generally in the form of myoclonic jerks and involves the upper extremities with or without head involvement. We sought to demonstrate the electrophysiological features in patients with Rasmussen syndrome. We performed continuous(More)
Our aim was to investigate the extent and pattern of involved pathways using brainstem and spinal reflexes by comparing primary progressive freezing of gait (PPFOG) progressive supranuclear palsy (PSP) with FOG. Seven patients with PPFOG and age and sex matched seven PSP patients and 16 healthy subjects were included in the study. All subjects underwent(More)
BACKGROUND AND OBJECTIVE We hypothesized that fear-conditioning may increase motor cortical excitability in preparation for response to fear. We tested our hypothesis in healthy subjects and in the second step, to determine the role of amygdala in alterations of motor cortex excitability, we included a group of patients who previously underwent unilateral(More)
Lafora disease is a rare, fatal, autosomal recessive progressive myoclonic epilepsy. The condition is characterised by seizures, myoclonus and dementia. In this case report, a patient who presented with generalised tonic-clonic seizures at the age of 30 is discussed. Until the age of 48, the patient did not have myoclonic jerks or ataxia clinically, but had(More)
OBJECTIVE We analyzed prepulse inhibition (PPI) of the blink reflex (BR) in patients with cervical dystonia (CD) to examine the sensory modulation of the motor system. METHODS This study enrolled 22 consecutive patients with idiopathic CD and 25 age- and gender-matched healthy subjects. Prepulse inhibition of the BR was recorded after stimulating the(More)
Intramuscular injections are likely the most common cause of sciatic nerve injury in developing countries. Less common causes include piriformis syndrome, primary tumors of the sciatic nerve, metastatic tumors invading or compressing the nerve, endometriosis, vascular malformations, and prolonged immobilization or positioning. While the most reliable(More)
