Can MS cause autonomic dysreflexia?

Background: Although autonomic dysreflexia (AD) is well documented in the spinal cord injury (SCI) population, its occurrence in persons with multiple sclerosis (MS) is not.

MS is, however, considered as a secondary cause, of central origin, for autonomic dysfunction. The most common autonomic symptoms in MS are disorders of micturation, impotence, sudomotor and gastrointestinal disturbances, orthostatic intolerance as well as sleep disorders.

The most common cause of autonomic dysreflexia (AD) is spinal cord injury. The nervous system of people with AD over-responds to the types of stimulation that do not bother healthy people.

• Constipation.
• Kidney stones.
• Urinary tract infection.
• Inserting a catheter, a medical tube.
• Hemorrhoids.
• Irritated or blistered skin.
• Pressure sores.
• Sunburn or hot water burns.

Multiple sclerosis (MS), affects both somatic and autonomic nervous system with a wide range of symptoms and signs. Less attention is paying to autonomic dysfunction, although they produce a serious impact on the patient management.

Conclusions: Prehypertension and hypertension are frequent in MS. Increased blood pressure is related to white- and gray-matter integrity, both related to MS disability outcomes. These findings suggest attention to the control of blood pressure in MS patients.

Syncope which is uncommon in MS patients occurred in almost 5/9(55%) of patients in this study. Increase in cerebrovascular resistance occurring during orthostatic stress can explain loss of consciousness in these patients (27).

Individuals with Multiple Sclerosis have a damaged vagus nerve which partially paralyses the stomach.

A key feature of autonomic dysfunction, either orthostatic syncope or presyncope, should guide us to suspicion of cardiovascular autonomic dysfunction. In this scenario, the usual symptoms are dizziness, giddiness, blurred or tunnel vision, headache, or neckache (coat-hanger pain), nausea, or fatigue.

Brown-Séquard syndrome is a rare spinal disorder that results from an injury to one side of the spinal cord in which the spinal cord is damaged but is not severed completely. It is usually caused by an injury to the spine in the region of the neck or back.

Neurogenic shock is a devastating consequence of spinal cord injury (SCI). It manifests as hypotension, bradyarrhythmia, and temperature dysregulation due to peripheral vasodilatation following an injury to the spinal cord.

Autonomic dysreflexia (AD) is a condition in which your involuntary nervous system overreacts to external or bodily stimuli. It’s also known as autonomic hyperreflexia. This reaction causes: a dangerous spike in blood pressure.

• dizziness.
• nausea.
• vomiting.
• blank stares.
• fainting.
• increased sweating.
• anxiety.
• pale skin.

The hypothalamus is the key brain site for central control of the autonomic nervous system, and the paraventricular nucleus is the key hypothalamic site for this control.

The parasympathetic nervous system is unable to slow the release. This is autonomic dysreflexia, an automatic reflex over-response that cannot be contained. Because the ANS is automatically controlled, you cannot consciously change or control your body’s autonomic dysreflexia response.

A lower than normal function of the sympathetic nervous system (SNS) has been identified early in the course of multiple sclerosis (MS) and has been shown to play a role in the pathology of the disease.

Myelin damage and the nervous system In multiple sclerosis, the protective coating on nerve fibers (myelin) in the central nervous system is damaged. This creates a lesion that, depending on the location in the central nervous system, may cause symptoms such as numbness, pain or tingling in parts of the body.

Abstract. The symptoms of cardiovascular autonomic dysfunction may be subtle and occur late in the course of diabetes. They include abnormal exercise-induced cardiovascular performance, postural hypotension, and cardiac denervation syndrome.

High Blood Pressure is Common in MS, Says New Study: Learn How to Stay Well. In a new study of millions of medical records, high blood pressure (hypertension) was 25% more common in people with MS compared to those without the disease, for reasons that are currently unclear.

People with multiple sclerosis are 48 percent more likely to have high blood pressure compared to the general population — and to people with other demyelinating diseases, a new study reports. Its researchers also emphasize that hypertension is already linked to poorer outcomes in MS patients.

Patients with multiple sclerosis (MS) who have significant variability in their systolic blood pressure readings tend to have higher disability levels, according to new research.

Respiratory dysfunction frequently occurs in patients with advanced multiple sclerosis (MS), and may manifest as acute or chronic respiratory failure, disordered control of breathing, respiratory muscle weakness, sleep disordered breathing, or neurogenic pulmonary edema.

The type you have depends on what causes the problem. Vasovagal syncope is the most common type of syncope. It is caused by a sudden drop in blood pressure, which causes a drop in blood flow to the brain. When you stand up, gravity causes blood to settle in the lower part of your body, below your diaphragm.

Vasovagal syncope (vay-zoh-VAY-gul SING-kuh-pee) occurs when you faint because your body overreacts to certain triggers, such as the sight of blood or extreme emotional distress. It may also be called neurocardiogenic syncope. The vasovagal syncope trigger causes your heart rate and blood pressure to drop suddenly.

Nearly two-thirds of MS patients have at least one GI symptom that persists for 6 months or more. Some of the most common problems are: 1) Dysphagia, 2) Heartburn, 3) Nausea, 4) Dyspepsia, 5) Diarrhea, 6) Constipation, and 7) Fecal Incontinence.

Many people with multiple sclerosis (MS) struggle with intestinal issues. There is evidence of the link between gut health and MS. Bloating is a common result of these issues. It’s super annoying and always happens at the worst time, such as when you’re out and about or wearing something fitted to an event.

The ‘MS hug’ is symptom of MS that feels like an uncomfortable, sometimes painful feeling of tightness or pressure, usually around your stomach or chest. The pain or tightness can stretch all around the chest or stomach, or it can be just on one side.

Autonomic dysfunction appears to result from autoimmune destruction of autonomic postganglionic and myenteric neurons. A variant of paraneoplastic autonomic neuropathy is an enteric neuronopathy that exists with antibodies directed against the myenteric plexus (anti-enteric neuronal antibodies).

Autoimmune autonomic ganglionopathy (AAG) is a condition in which the body’s immune system mistakenly attacks and damages certain parts of the autonomic nervous system. AAG may be divided into two different types based on the presence of specific types of cells in the blood that normally fight infection (antibodies).

It is not fatal. Pure autonomic failure is caused by abnormal accumulation of synuclein in the brain. Blood pressure may decrease when people stand, and they may sweat less and may have eye problems, retain urine, become constipated, or lose control of bowel movements.

A syndrome associated with injury to the lateral half of the spinal cord.

What Does Sacral Sparing Indicate? Sacral sparing is used to help diagnose whether a person’s spinal cord injury is complete or incomplete. With complete spinal cord injuries, all sensory and motor functions below your level of injury are affected because signals from the brain cannot travel past the spinal lesion.

Syringomyelia (sih-ring-go-my-E-lee-uh) is the development of a fluid-filled cyst (syrinx) within your spinal cord. Over time, the cyst can enlarge, damaging your spinal cord and causing pain, weakness and stiffness, among other symptoms.

Hypovolemic shock is a dangerous condition that happens when you suddenly lose a lot of blood or fluids from your body. This drops your blood volume, the amount of blood circulating in your body. That’s why it’s also known as low-volume shock. Hypovolemic shock is a life-threatening emergency.

The cause of neurogenic shock is usually a spinal cord injury. When the nerves in the spinal cord are damaged, they stop sending messages to the nerves that control other functions in the body. If nerve signals to the muscles in the blood vessels are shut down, the vessels stop working properly.

Decompensated shock is defined as “the late phase of shock in which the body’s compensatory mechanisms (such as increased heart rate, vasoconstriction, increased respiratory rate) are unable to maintain adequate perfusion to the brain and vital organs.” It occurs when the blood volume decreases by more than 30%.

Autonomic dysreflexia (AD) is a condition wherein the thoracolumbar sympathetic nervous system reacts to a stimulus in an unmitigated and unregulated manner. This may result in symptoms ranging from mild discomfort to extremely severe and occasionally damaging hypertensive crises.

The most commonly used agents are nifedipine and nitrates (eg, nitroglycerine paste or sublingual nitroglycerine). Nifedipine should be in the immediate-release form; bite and swallow is the preferred method of administering the drug, not sublingual administration.

Autonomic dysreflexia causes an imbalanced reflex sympathetic discharge, leading to potentially life-threatening hypertension. It is considered a medical emergency and must be recognized immediately.

Neurogenic shock and spinal shock are two separate conditions that are often confused for one another because they can both occur after a spinal cord injury. Additionally, they can also share symptoms including hypotension and bradycardia.
