26. A randomized controlled cross-over double blind study protocol on THC/CBD oromucosal spray as an add-on therapy for post-stroke spasticity

Understand if cannabinoids (THC:CBD) are useful in reducing post-stroke spasticity using a neurophysiological quantitative measure as primary endpoint.We will recruit 50 patients with spasticity following stroke to take THC:CBD in a double blind placebo-controlled crossover study. Spasticity will be assessed with a numeric rating scale for spasticity, the modified Ashworth scale and with the electromyographic recording of the stretch reflex. The cardiovascular risk will be assessed prior to inclusion.

Conclusion: Evidence gathered from this systematic review of literature is inconclusive due to the lack of research focusing on those with tetraplegia. Higher power studies (level 1-3) are needed with the focus on those with tetraplegia. PMID: 32043944 [PubMed - as supplied by publisher]

Milsom The cardiovascular system is critical for delivering O2 to tissues. Here we examine the cardiovascular responses to progressive hypoxia in four high-altitude Andean duck species compared to four related low-altitude populations in North America, tested at their native altitude. Ducks were exposed to stepwise decreases in inspired partial pressure of O2 while we monitored heart rate, O2 consumption rate, blood O2 saturat...

In this study, we investigated the effect of unilateral muscle hypertonia on ipsilateral cortical activity and contralateral motor function. Fourteen right-handed healthy young subjects lifted a weight of 10% body weight with the right upper limb to increase muscle tone (weight task), while no weight lifting was set as the control ‘nonweight’ task. We recorded the motor-evoked potential (MEP), resting motor threshold and H-reflex from the left flexor carpi radialis muscle during both tasks. To estimate the functional effect of the weight task, subjects performed the ‘Purdue pegboard test’, consistin...

We describe a case of a 57-year-old man who, immediately after a right parietal ischemic stroke, showed urodynamically determined bladder sensory decrement during filling and an underactive detrusor during voiding, both of which were ameliorated during the course of his treatment. The lower urinary tract symptom (LUTS) occurs in stroke in up to 60% of patients, when it involves the frontal and insular cortices. In addition, LUTS does occur in parietal stroke as seen in our patient, presumably by sensory deafferentiation within the brain that is relevant to the central regulation of the micturition reflex.

The vagus nerve plays an important role in maintaining physiological homeostasis, which includes reflex pathways that regulate cardiac function. The link between vagus nerve activity and the high-frequency component of heart rate variability (HRV) has been well established, correlating with vagal tone. Recently, vagus nerve stimulation (VNS) has been investigated as a therapeutic for a multitude of diseases, such as treatment-resistant epilepsy, rheumatoid arthritis, Crohn's disease, and asthma. Because of the vagus nerve's innervation of the heart, VNS has been identified as a potential therapy for cardiovascular disorder...

Abstract Oligodendrocytes (OLs) generate myelin membranes for the rapid propagation of electrical signals along axons in the central nervous system (CNS) and provide metabolites to support axonal integrity and function. Differentiation of OLs from oligodendrocyte progenitor cells (OPCs) is orchestrated by a multitude of intrinsic and extrinsic factors in the CNS. Disruption of this process, or OL loss in the developing or adult brain, as observed in various neurological conditions including hypoxia/ischemia, stroke, and demyelination, results in axonal dystrophy, neuronal dysfunction, and severe neurological impai...

AbstractRecurrent spontaneous vasospasm of the extracranial internal carotid artery (RSV-eICA) is a rarely recognized cause of ischemic stroke in young adults. However, its pathophysiology remains largely unknown. Through whole-exome sequencing of the ACOX3 gene of two dizygotic Korean twin brothers affected by RSV-eICA, we identified two compound heterozygous missense variants c.235  T >  G (p.F79 V) and c.665G >  A (p.G222E). In silico analysis indicated that both variants were classified as pathogenic. In vitro ACOX3 enzyme assay indicated practically no enzyme activity in bot...

Abstract Although the prevalence of muscle weakness in the general population is uncertain, it occurs in about 5% of U.S. adults 60 years and older. Determining the cause of muscle weakness can be challenging. True muscle weakness must first be differentiated from subjective fatigue or pain-related motor impairment with normal motor strength. Muscle weakness should then be graded objectively using a formal tool such as the Medical Research Council Manual Muscle Testing scale. The differential diagnosis of true muscle weakness is extensive, including neurologic, rheumatologic, endocrine, genetic, medication- or tox...

Semin Neurol DOI: 10.1055/s-0039-3400315Cerebellar dizziness and vertigo account for approximately 10% of diagnoses in a tertiary dizziness center. This term summarizes a large group of disorders with chronic (degenerative, hereditary, acquired cerebellar ataxias), recurrent (episodic ataxias), or acute (stroke, inflammation) presentations. Key to the diagnosis is a comprehensive examination of central ocular motor and vestibular function. Patients with cerebellar dizziness and vertigo usually show a pattern of deficits in smooth pursuit, gaze-holding, saccade accuracy, or fixation-suppression of the vestibulo-ocular refle...
