Neurogenic Hypertension: Symptoms and Risks
Neurogenic hypertension is a condition characterized by high blood pressure that is primarily caused by abnormalities in the nervous system. This type of hypertension can have a significant impact on overall health as it disrupts the normal regulation of blood pressure by the nervous system, leading to persistent elevated blood pressure levels. This can put strain on the heart and blood vessels, increasing the risk of cardiovascular complications and other health issues. Proper management and treatment are essential to prevent long-term complications associated with neurogenic hypertension.
What are the Symptoms of Neurogenic Hypertension
Neurogenic hypertension can present with a variety of symptoms related to the nervous system's influence on blood pressure regulation.
- Severe headache
- Blurred vision
- Chest pain
- Fatigue
- Nausea
- Shortness of breath
- Dizziness or lightheadedness
- Irregular heartbeat
- Sweating
- Anxiety or nervousness

Get Second OpinionCauses of Neurogenic Hypertension
The primary cause of Neurogenic hypertension is an overactivity of the sympathetic nervous system, leading to increased blood pressure.
- Chronic stress
- Brain tumors
- Spinal cord injuries
- Autonomic nervous system disorders
- Certain medications
- Stroke
- Multiple system atrophy
- Parkinson's disease
Types of Neurogenic Hypertension
Neurogenic hypertension can manifest in various forms, each stemming from different underlying causes related to the nervous system.
- Autonomic Dysreflexia: A sudden, dangerous increase in blood pressure that can occur in individuals with spinal cord injuries above the T6 level.
- Pheochromocytoma: A rare tumor of the adrenal gland that can cause episodes of high blood pressure due to excessive release of catecholamines.
- Baroreceptor Dysfunction: Impaired function of the baroreceptors, leading to dysregulation of blood pressure control mechanisms in the body.
- Cerebrovascular Disease: Conditions such as strokes or aneurysms that can disrupt the normal regulation of blood pressure in the brain.
- Postural Orthostatic Tachycardia Syndrome (POTS): A form of dysautonomia where changes in body position lead to symptoms like dizziness and increased heart rate, potentially affecting blood pressure regulation.
Risk Factors
Neurogenic hypertension risk factors include conditions such as brain tumors, head injuries, and certain medications that can disrupt the normal functioning of the nervous system and lead to elevated blood pressure.
- Spinal cord injuries
- Brain tumors
- Multiple sclerosis
- Stroke
- Autonomic dysreflexia
- Parkinson's disease
- Brain trauma
- Spinal cord tumors
- Spinal cord lesions

Diagnosis of Neurogenic Hypertension
Neurogenic hypertension is typically diagnosed through a series of tests to determine the underlying cause of high blood pressure.
- Blood pressure monitoring
- Electrocardiogram (ECG)
- Echocardiogram
- Blood tests for hormone levels
- MRI scan of the brain and spinal cord
Treatment for Neurogenic Hypertension
Neurogenic hypertension is generally managed by addressing the underlying neurological causes to help regulate blood pressure.
- Medications: Various drugs like alpha blockers, beta blockers, and calcium channel blockers are used to manage neurogenic hypertension by controlling blood pressure levels.
- Lifestyle Modifications: Adopting a healthy lifestyle through regular exercise, maintaining a balanced diet, reducing stress, and limiting alcohol consumption can help in managing neurogenic hypertension.
- Surgical Interventions: In severe cases, surgical procedures such as renal denervation or sympathectomy may be considered to treat neurogenic hypertension.
- Neurostimulation: Techniques like carotid baroreceptor stimulation or spinal cord stimulation are emerging as potential options to modulate neural pathways and regulate blood pressure in neurogenic hypertension patients.
- Psychological Support: Counseling or therapy can play a crucial role in managing the psychological aspects of neurogenic hypertension, such as anxiety and stress, which can contribute to elevated blood pressure levels.

What is neurogenic hypertension?
Neurogenic hypertension is high blood pressure that is caused by a dysfunction in the central nervous system, leading to abnormal regulation of blood pressure.
What are the common causes of neurogenic hypertension?
Common causes include conditions such as brain tumors, head injuries, strokes, and certain neurological disorders that affect the central nervous system's control over blood pressure.
What are the symptoms of neurogenic hypertension?
Symptoms may include severe headaches, dizziness, vision problems, chest pain, and shortness of breath. In some cases, there may be no noticeable symptoms.
How is neurogenic hypertension diagnosed?
Diagnosis typically involves a thorough medical history, physical examination, blood pressure monitoring, and imaging tests such as MRI or CT scans to identify underlying causes.
What are the treatment options for neurogenic hypertension?
Treatment may involve addressing the underlying cause, lifestyle modifications, medications to lower blood pressure, and in some cases, surgical intervention to correct the neurological issue contributing to high blood pressure.
