Vascular diseases of the brain and spinal cord refer to conditions that affect the blood vessels supplying these areas. These conditions can disrupt the normal blood flow, leading to various symptoms and potential complications.


There are various types of vascular diseases that can affect the brain and spinal cord. Here are some common types:

1. Ischemic Stroke: This occurs when there is a blockage or narrowing of blood vessels supplying the brain, leading to a decrease in blood flow and oxygen. Ischemic strokes can be caused by blood clots (thrombotic strokes) or by clots that travel from other parts of the body (embolic strokes).

2. Hemorrhagic Stroke: This type of stroke happens when a blood vessel in the brain ruptures, causing bleeding into the surrounding tissues. Hemorrhagic strokes can be caused by conditions like aneurysms, arteriovenous malformations (AVMs), or high blood pressure.

3. Transient Ischemic Attack (TIA): Also known as a mini-stroke, a TIA is a temporary disruption of blood flow to the brain. TIAs usually last only a few minutes and do not cause permanent damage. However, they can serve as warning signs of an increased risk of a future stroke.

4. Cerebral Aneurysm: A cerebral aneurysm is a weak or bulging area in the wall of a blood vessel in the brain. If an aneurysm ruptures, it can cause a subarachnoid hemorrhage, a type of stroke. Aneurysms can develop due to factors such as high blood pressure, smoking, or a family history of aneurysms.

5. Arteriovenous Malformation (AVM): An AVM is an abnormal tangle of blood vessels in the brain or spinal cord. These vessels can rupture and cause bleeding, leading to a hemorrhagic stroke. AVMs are typically present at birth and can cause symptoms such as headaches, seizures, or neurological deficits.

6. Carotid Artery Disease: Carotid artery disease refers to the narrowing or blockage of the carotid arteries, the major blood vessels in the neck that supply blood to the brain. This condition can increase the risk of stroke if a blood clot forms and travels to the brain.

7. Spinal Cord Vascular Malformations: Vascular malformations, such as arteriovenous fistulas (AVFs) or cavernous malformations, can occur in the blood vessels of the spinal cord. These abnormalities can disrupt blood flow and cause symptoms such as back or neck pain, weakness, or sensory changes.


Vascular diseases of the brain and spinal cord can cause a range of symptoms, depending on the specific condition and the area of the affected blood vessels. Here are some common symptoms associated with these conditions:

1. Stroke

  • Sudden weakness or numbness, often on one side of the body
  • Difficulty speaking or understanding speech
  • Vision changes or loss of vision in one or both eyes
  • Sudden severe headache
  • Dizziness or loss of balance
  • Confusion or trouble with coordination
  • Facial drooping or weakness

2. Transient Ischemic Attack (TIA)

  • Temporary weakness or numbness, often on one side of the body
  • Difficulty speaking or understanding speech
  • Temporary loss of vision or blurred vision
  • Brief episodes of dizziness or loss of balance
  • Confusion or memory loss

TIA symptoms usually resolve within 24 hours, but they should never be ignored as they can be warning signs of an increased risk of a future stroke.

3. Cerebral Aneurysm

  • Sudden and severe headache (“worst headache of your life”)
  • Neck pain or stiffness
  • Blurred or double vision
  • Sensitivity to light
  • Nausea and vomiting
  • Loss of consciousness or seizures if the aneurysm ruptures

4. Arteriovenous Malformation (AVM)

  • Headaches, often severe and persistent
  • Seizures, sometimes the first sign of an AVM
  • Weakness or numbness in one part of the body
  • Problems with vision, speech, or coordination
  • Memory or cognitive difficulties

5. Carotid Artery Disease

  • Weakness or numbness on one side of the face or body
  • Trouble speaking or understanding speech
  • Vision changes, such as blurred vision or sudden loss of vision in one eye
  • Dizziness or loss of balance
  • Severe headache

6. Spinal Cord Vascular Malformations

  • Back or neck pain
  • Weakness or paralysis in the arms or legs
  • Loss of sensation or tingling in the limbs
  • Problems with coordination or balance
  • Bowel or bladder dysfunction


The study of the patient’s medical history, a physical examination, and other diagnostic procedures are often combined to make the diagnosis of vascular disorders of the brain and spinal cord. Here are a few typical techniques for diagnosis:

1. Medical history and physical exam: To evaluate neurological function and check for vascular disease symptoms, a healthcare expert will analyse your symptoms, medical history, and physical exam.

2. Imaging tests: A variety of imaging methods may be used to see the blood vessels and spot anomalies. These may consist of:

  • Computed Tomography (CT) scan: This test produces fine-grained cross-sectional pictures of the brain or spinal cord using X-rays, enabling medical professionals to see bleeding, blood clots, or specific vascular abnormalities.
  • Magnetic Resonance Imaging (MRI): MRI creates precise pictures of the brain or spinal cord using strong magnets and radio waves. It may provide details about blood flow and identify vascular abnormalities such as aneurysms, AVMs, and strokes.
  • Angiography: This invasive process includes injecting contrast dye into blood arteries and collecting X-ray pictures. It makes the blood vessels more visible and makes it easier to see specific problems.
  • Doppler ultrasound: This non-invasive test measures blood flow via the blood arteries using sound waves and may spot regions of obstruction or constriction.

3. Blood testing: Blood tests may be performed to check for clotting issues, cholesterol levels, blood sugar levels, and other vascular disease risk factors.

4. Electrophysiological examinations: To evaluate electrical activity in the brain or spinal cord, electrophysiological procedures like electroencephalography (EEG) or nerve conduction studies may sometimes be carried out.

5. Lumbar puncture (spinal tap): A lumbar puncture may be performed in certain circumstances to check the cerebrospinal fluid for indications of infection or bleeding.


The exact state and severity of vascular disorders of the brain and spinal cord determine the course of therapy. Preventing additional harm, managing symptoms, and enhancing general quality of life are the objectives of therapy. Here are some typical medical options:

1. Medications: To treat symptoms and lower the risk of complications, medications are often administered. These may consist of:

  • Antiplatelet medicines help prevent blood clotting and lower the risk of stroke. Examples include aspirin and clopidogrel.
  • Anticoagulant, such as warfarin or direct oral anticoagulants, are used to stop the growth or development of blood clots.
  • Medication to lower blood pressure since managing high blood pressure is crucial for treating vascular disorders.
  • Drugs like statins, which may help lower cholesterol levels and lessen the chance of plaque accumulation in blood vessels.

2. Surgical interventions: To treat vascular disorders, surgery may sometimes be required. These can include:

  • Endovascular procedures: Minimally invasive techniques, such as angioplasty or stent placement, can be used to open narrowed or blocked blood vessels.
  • Clipping or coiling: For cerebral aneurysms, surgical procedures like clipping or coiling may be performed to prevent rupture or re-rupture.
  • Aneurysm or AVM removal: In certain situations, the surgical removal of an aneurysm or arteriovenous malformation may be required.

3. Rehabilitation therapy: For individuals who have experienced strokes or other neurological impairments due to vascular diseases, rehabilitation therapy plays a crucial role in maximizing recovery. This may involve physical therapy, occupational therapy, speech therapy, or other specialized therapies depending on the specific needs.

4. Lifestyle modifications: Adopting a healthy lifestyle can help manage vascular diseases and reduce the risk of complications. This may include:

  • Eating a balanced diet low in saturated fats and sodium
  • Engaging in regular physical exercise
  • Maintaining a healthy weight
  • Managing stress
  • Avoiding smoking and excessive alcohol consumption
