The Functional Role of Spinal Interneurons Following Traumatic Spinal Cord Injury.

Front Cell Neurosci 2020 18;14:127. Epub 2020 May 18.

Division of Genetics and Development, Krembil Research Institute, University Health Network, Toronto, ON, Canada.

Traumatic spinal cord injury (SCI) impedes signal transmission by disrupting both the local neurons and their surrounding synaptic connections. Although the majority of SCI patients retain spared neural tissue at the injury site, they predominantly suffer from complete autonomic and sensorimotor dysfunction. While there have been significant advances in the characterization of the spared neural tissue following SCI, the functional role of injury-induced interneuronal plasticity remains elusive.

Intraspinal Plasticity Associated With the Development of Autonomic Dysreflexia After Complete Spinal Cord Injury.

Front Cell Neurosci 2019 8;13:505. Epub 2019 Nov 8.

Department of Physiology, Spinal Cord and Brain Injury Research Center, University of Kentucky, Lexington, KY, United States.

Traumatic spinal cord injury (SCI) leads to disruption of sensory, motor and autonomic function, and triggers structural, physiological and biochemical changes that cause reorganization of existing circuits that affect functional recovery. Propriospinal neurons (PN) appear to be very plastic within the inhibitory microenvironment of the injured spinal cord by forming compensatory circuits that aid in relaying information across the lesion site and, thus, are being investigated for their potential to promote locomotor recovery after experimental SCI. Yet the role of PN plasticity in autonomic dysfunction is not well characterized, notably, the disruption of supraspinal modulatory signals to spinal sympathetic neurons after SCI at the sixth thoracic spinal segment or above resulting in autonomic dysreflexia (AD).

Spinal cord injury (SCI) can have profound effects on the autonomic and cardiovascular systems, notably with injuries above high-thoracic levels that result in the development of autonomic dysreflexia (AD) characterized by volatile hypertension in response to exaggerated sympathetic reflexes triggered by afferent stimulation below the injury level. Pathophysiological changes associated with the development of AD include sprouting of both nociceptive afferents and ascending propriospinal 'relay' neurons below the injury, as well as dynamic changes in synaptic inputs onto sympathetic preganglionic neurons. However, it remains uncertain whether synapse formation between sprouted c-fibers and propriospinal neurons contributes to the development of exaggerated sympathetic reflexes produced during AD.

Headache Attributed to Autonomic Dysreflexia: Clinical Presentation, Pathophysiology, and Treatment.

Curr Pain Headache Rep 2019 Aug 27;23(11):80. Epub 2019 Aug 27.

Department of Neurology, Mayo Clinic College of Medicine, 200 First St. SW, Floor 8, Rochester, MN, 55905, USA.

A patient presenting with marked elevation in blood pressure and concurrent headache often presents a diagnostic challenge for even the most seasoned clinician. When marked hypertension and headache occur in a patient with a history of upper spinal cord injury, the patient should be presumed to have autonomic dysreflexia until proven otherwise. Autonomic dysreflexia can at times trigger headaches, hypertension, and variations in pulse, as well other autonomic signs and symptoms. Read More

Cureus 2019 Mar 20;11(3):e4285. Epub 2019 Mar 20.

Neurology, University of Missouri, Columbia, USA.

Reversible cerebral vasoconstriction syndrome (RCVS) is a rare neurological condition that typically presents with a sudden-onset thunderclap headache associated with or without focal neurological deficits. The diagnosis is established by the presence of reversible segmental or diffuse cerebral vasoconstriction on diagnostic cerebral angiogram. Autonomic dysreflexia is a known complication resulting from spinal cord injury. Read More

Long-term neurogenic lower urinary tract dysfunction: A case of cardiovascular nightmares.

J Spinal Cord Med 2019 May 29:1-5. Epub 2019 May 29.

a International Collaboration on Repair Discoveries (ICORD), Faculty of Medicine , University of British Columbia , Vancouver , British Columbia , Canada.

Individuals with spinal cord injury (SCI) suffering from autonomic dysreflexia (AD) due to neurogenic detrusor overactivity (NDO) can effectively be treated with intradetrusor onabotulinumtoxinA. We present a complex case to highlight the treatment's potential limitations to ameliorate AD and improve lower urinary tract (LUT) function in this population. A 46-year old man, who was relying on an indwelling urethral catheter for bladder emptying due to severely impaired hand function following a SCI (C5, AIS B) sustained 30 years ago, underwent intradetrusor onabotulinumtoxinA injections for treatment of refractory NDO and associated AD.

PRES secondary to autonomic dysreflexia: A case series and review of the literature.

J Spinal Cord Med 2019 May 29:1-7. Epub 2019 May 29.

d Department of Physical Medicine and Rehabilitation , University of British Columbia , Vancouver , BC , Canada.

Autonomic dysreflexia (AD) is a complex syndrome seen in patients with spinal cord injuries (SCI) and can be life-threatening with a significant negative impact on the health of the individual. Posterior reversible encephalopathy syndrome (PRES) is thought to be caused, in part, by rapid elevations in blood pressure; leading to posterior cerebral circulatory edema. This can result in seizures, blindness and can progress to fatal intracranial hemorrhages. Read More

The Blood Pressure Pendulum following Spinal Cord Injury: Implications for Vascular Cognitive Impairment.

Int J Mol Sci 2019 May 18;20(10). Epub 2019 May 18.

International Collaboration on Repair Discoveries (ICORD), University of British Columbia, Vancouver, BC V5Z 1M9, Canada.

Cognitive impairment following spinal cord injury (SCI) has received considerable attention in recent years. Among the various systemic effects of SCI that contribute towards cognitive decline in this population, cardiovascular dysfunction is arguably one of the most significant. The majority of individuals with a cervical or upper-thoracic SCI commonly experience conditions called orthostatic hypotension and autonomic dysreflexia, which are characterized by dangerous fluctuations in systemic blood pressure (BP).

Development of a decerebrate model for investigating mechanisms mediating viscero-sympathetic reflexes in the spinalized rat.

Am J Physiol Heart Circ Physiol 2019 06 15;316(6):H1332-H1340. Epub 2019 Mar 15.

Department of Emergency Medicine, Wayne State University School of Medicine , Detroit, Michigan.

Autonomic dysreflexia (AD) often occurs in individuals living with spinal cord injury (SCI) and is characterized by uncontrolled hypertension in response to otherwise innocuous stimuli originating below the level of the spinal lesion. Visceral stimulation is a predominant cause of AD in humans and effectively replicates the phenotype in rodent models of SCI. Direct assessment of sympathetic responses to viscerosensory stimulation in spinalized animals is challenging and requires invasive surgical procedures necessitating the use of anesthesia. Read More

Protocol for a phase II, open-label exploratory study investigating the efficacy of fesoterodine for treatment of adult patients with spinal cord injury suffering from neurogenic detrusor overactivity for amelioration of autonomic dysreflexia.

BMJ Open 2018 11 21;8(11):e024084. Epub 2018 Nov 21.

International Collaboration on Repair Discoveries (ICORD), Faculty of Medicine, University of British Columbia, Vancouver, British Columbia, Canada.

Introduction: Managing and preventing risk factors associated with cardiovascular and cerebrovascular impairment is well studied in able-bodied individuals. However, individuals with spinal cord injury (SCI) at or above the spinal segment T6 are prone to experience autonomic dysreflexia (AD) but also to suffer from neurogenic detrusor overactivity (NDO). Treatment of NDO would not only improve lower urinary tract function but could also reduce the severity and frequency of life-threatening episodes of AD. Read More
