Vascular dementia (VaD) is a condition characterised by cognitive changes that can impact various thinking skills. It often leads to difficulties in memory, speech, and balance.

Cognitive abilities may naturally decline with age. But in certain instances, cognitive impairment can be attributed to specific conditions, like vascular dementia (VaD). Unlike other forms of dementia, vascular dementia stems from impaired blood flow to the brain. This leads to cognitive decline. 

In this blog post, we will explore the symptoms, causes, and risk factors associated with VaD, offering insights into this intricate condition that affects the cognitive functioning of individuals. By understanding these aspects, we can better grasp the impact of vascular dementia and its unique characteristics in comparison to other types of dementia.

Understanding Vascular Dementia (VaD)

Vascular dementia ranks as the second most prevalent form of dementia. You must know the fact that it trails only behind Alzheimer’s disease. This condition arises from the impairment or blockage of blood vessels in the brain. If this happens, it leads to diminished blood flow and oxygen supply. The severity of symptoms can fluctuate significantly, contingent upon the extent and location of the vascular damage. 

While some individuals may encounter a sudden onset of symptoms, others may witness a more gradual progression. Understanding the diverse manifestations and progression patterns of VaD is crucial for both affected individuals and their caregivers. This helps them in navigating the challenges posed by this condition and seeking appropriate management strategies.

Symptoms of Vascular Dementia

The symptoms of vascular dementia can manifest differently in each individual. But there are common signs to watch out for. Some common symptoms of vascular dementia are as follows:

  • Memory loss: Difficulty in remembering recent events or new information.
  • Problems with language and communication: Struggling to find the right words or understand conversations.
  • Impaired judgement and decision-making: Difficulty making sound decisions or solving problems.
  • Difficulty with planning and organizing: Struggling with tasks that require logical thinking and coordination.
  • Confusion and disorientation: Getting lost in familiar surroundings or becoming easily disoriented.
  • Changes in mood and behaviour: Experiencing mood swings, depression, or apathy.

Causes of Vascular Dementia

Vascular dementia (VaD) happens when conditions damage the blood vessels. This causes a reduction or blockage of blood flow to the brain. It may result from factors such as a stroke, which blocks an artery and causes a variety of symptoms like changes in memory, thinking, or movement. Other conditions like diabetes or high blood pressure can also damage the blood vessels over time, eventually causing problems with memory or thinking abilities. 

Conditions that affect the blood vessels and circulation in the brain are what primarily cause VaD. The following factors contribute to its development:

  • Stroke: A major risk factor for vascular dementia, especially if it affects multiple areas of the brain.
  • Small vessel disease: Damage to the tiny blood vessels in the brain due to conditions like high blood pressure, diabetes, or high cholesterol.
  • Blood vessel blockage: When a blood clot obstructs blood flow to the brain, it can lead to vascular dementia.
  • Transient ischaemic attacks (TIAs): Repeated TIAs, also known as “mini-strokes,” can cause cumulative damage to the brain.

What are the risk factors?

Several factors increase the risk of developing vascular dementia. These include:

  • Age: The risk of VaD increases with age, particularly after the age of 65.
  • Hypertension: High blood pressure damages blood vessels and increases the risk of cognitive decline.
  • Diabetes: Poorly controlled diabetes can lead to vascular damage and increase the risk of dementia.
  • High cholesterol: Elevated cholesterol levels contribute to the development of atherosclerosis, narrowing blood vessels.
  • Smoking: Smoking damages blood vessels and increases the risk of stroke and cognitive impairment.
  • Obesity: Excess weight and an unhealthy lifestyle can contribute to vascular problems and cognitive decline.

Treatments of Vascular Dementia

There is currently no cure for vascular dementia. But its symptoms can be cured. There are medications available that can help control its symptoms. Sometimes, the same medications used to treat memory issues in Alzheimer’s disease, can also be beneficial for managing VaD. Additionally, people with vascular dementia might experience changes in their mood, like feeling sad or easily annoyed. Fortunately, there are medications, similar to those used for treating depression or anxiety, that can help manage these mood changes effectively. These medications can provide relief and improve the overall well-being of individuals with VaD.

Besides taking medications, there are many ways to support someone with vascular dementia. Studies have found that staying active through exercise and maintaining a healthy weight can be helpful. It can boost brain health and lower the chances of heart issues, stroke, and other diseases that harm blood vessels. Some helpful activities are as follows:

  • Eating a well-balanced diet
  • Getting enough sleep, and
  • Not drinking too much alcohol

By maintaining a healthy weight and lifestyle, a patient can keep the brain in good shape and reduce the risk of heart disease. If there are other health conditions like diabetes, high blood pressure, or high cholesterol, it’s crucial to treat them properly since they can also affect the brain. By taking care of our overall health and making smart lifestyle choices, we can make a positive impact on the well-being of someone with vascular dementia.

Wrapping Up

Vascular dementia (VaD)is a complicated problem that affects many people all over the world. It’s important to know the signs, causes, and things that increase the chances of getting it. By recognising these things, taking care of our blood vessels, and making healthy changes to our lifestyle, we can lower the risk of getting vascular dementia and keep our brains healthy. 

If you or someone you care about starts having problems with memory or thinking, it’s really important to see a doctor to figure out what’s causing it and get the right help. You can consult Dr. (Prof.) Digvijay Sharma who is a renowned Endovascular and Vascular Surgeon. Remember, when it comes to vascular dementia, knowing about it can make a big difference, so tell others and support those who are dealing with this condition.
