Mechanisms of hypnotic analgesia were investigated by examining changes in the R-III, a nociceptive spinal reflex, during hypnotic reduction of pain sensation and unpleasantness. The R-III was measured in 15 healthy volunteers who gave VAS-sensory and VAS-affective ratings of an electrical stimulus during conditions of resting wakefulness, suggestions for(More)
The average annual incidence of subarachnoid hemorrhage (SAH) from aneurysm rupture in Rochester, Minnesota, has remained remarkably constant at about 11 per 100,000 population. Age-specific incidence increased with age. Survival after SAH depended on: (1) clinical grade, (2) time after onset of SAH, and (3) presence of intracerebral hematoma. Among those(More)
BACKGROUND There is some evidence that patients with Parkinson's disease may impaired in prospective memory performance (planning and self initiated realisation of delayed intentions). Little is known about the effect of the disease on distinct phases of prospective memory and the potential mechanisms underlying these effects. OBJECTIVE To investigate(More)
Mitochondria are abnormal in persons with amyotrophic lateral sclerosis (ALS) for unknown reasons. We explored whether aberration of mitochondrial DNA (mtDNA) could play a role in this by transferring mitochondrial DNA (mtDNA) from ALS subjects to mtDNA-depleted human neuroblastoma cells. Resulting ALS cytoplasmic hybrids (cybrids) exhibited abnormal(More)
Our knowledge of the specific root innervation of skeletal muscles is derived from accumulated clinical experience. While performing selective posterior rhizotomy for treatment of spasticity in children with cerebral palsy, we made direct electrophysiologic measurement of the root innervation of the lower extremity. We stimulated ventral roots from L2 to S2(More)
Myasthenia gravis and Lambert-Eaton syndrome are autoimmune disorders of the neuromuscular junction. The most common form of myasthenia gravis is associated with antibodies directed against the acetylcholine receptor on the postsynaptic membrane. In Lambert-Eaton syndrome, antibodies are directed against P/Q-type voltage-gated calcium channels on(More)
Our objective was to determine the effect of creatine monohydrate on disease progression in patients with amyotrophic lateral sclerosis (ALS). One hundred and seven patients with the diagnosis of probable or definite ALS, of less than five years duration from symptom onset, were randomized to either treatment with daily creatine monohydrate (5 g/d) or(More)
The inheritance of the hereditary motor and sensory neuropathies (HMSN) is usually autosomal dominant. We studied a kinship with a pattern of X-linked dominant inheritance. The phenotype was similar to HMSN of the "intermediate" type. Men were more severely affected than women, and hypertrophic nerves were not found. Nerve conduction was very slow in men,(More)
R+ pramipexole (PPX) is a lipophilic cation that concentrates into brain and mitochondria and efficiently scavenges reactive oxygen and nitrogen species (RONS). Under the auspices of a Physician-Sponsor IND, R+PPX was dosed to small numbers of ALS patients for tolerability and safety while efficacy measures were also collected. The purpose of this paper is(More)
An electrophysiological study was made of 30 normal subjects aged 20 to 70 years. Routine methods were used to measure peripheral motor and sensory functions of the posterior tibial nerve. This nerve was then stimulated at the ankle and recordings made simultaneously over the thoraco-lumbar spine, cervical spine and central sensory cortex. Peripheral and(More)
