Somatosympathetic reflex was studied in 29 patients with definite multiple sclerosis (MS) by the non-invasive sympathetic skin response (SSR) method. Abnormal SSRs in 1 or more limbs were noted in 17 patients. Good correlation between the number of absent SSRs and the severity of the disability caused by MS was observed. Delayed or absent SSRs correlated(More)

The sympathetic skin response (SSR) is the potential generated by sweat in response to different stimuli. This potential has a waveform that habituates with closely repeated stimuli and a latency of 1.3-1.5 s at the hand and 1.9-2.1 s at the foot. It has been used to study the peripheral sympathetic system in peripheral nerve diseases. The response is(More)
We present five elderly patients with focal reflex or posture-induced seizures and nonketotic hyperglycemia (NKH). Each patient exhibited interictal focal findings, such as hemiparesis or hemisensory or aphasic deficits. With control of the hyperglycemia, the seizures stopped, and the neurologic deficits resolved. The syndrome of focal reflex epilepsy and(More)
Assessment of possible autonomic nervous system dysfunction was performed by testing cardiovascular reflexes in nine patients with progressive supranuclear palsy (PSP). The patients were significantly different from 15 control age-matched subjects because of greater blood pressure drop on standing for 1 min, diminished rise of diastolic blood pressure(More)
OBJECTIVE To test the presumption that Lhermitte's sign in multiple sclerosis is the result of a lesion in the cervical spinal cord. DESIGN The radiologic files of 887 patients with multiple sclerosis were reviewed. A detailed questionnaire regarding Lhermitte's sign was sent to 75 patients who had undergone magnetic resonance imaging of the brain and(More)
BACKGROUND Many patients with epilepsy travel abroad and drive automobiles with the assumption that policies, rules, and regulations on epilepsy and driving are similar to those of their home countries. This paper investigates the driving restrictions and other pertinent information on this issue in foreign countries. METHODS A questionnaire was sent to(More)
