Top 5 Causes of Dementia in the Elderly

Main Causes of Dementia in the Elderly in Newcastle, SW

Dementia is an age-related disease that results from biological changes or mechanical injuries that take place in a senior’s body. Even though genetic issues have been linked with various forms of dementia, it is difficult to predict who will develop the condition and who will not.

Although dementia is fairly common among ageing adults, it is not the only disease they are susceptible to. Seniors can face a variety of challenges as they age, many of which can be mitigated with the help of professional in-home caregivers who provide high-quality elderly care. Newcastle families trust in Home Care Assistance to help their elderly loved ones age in place safely and comfortably.

Here’s a look at some of the top causes of dementia in the elderly. 

1. Cerebrovascular Damage 

This is the most common cause of dementia, which takes place when the blood vessels in the brain are damaged. The blood vessels that supply the brain become narrow and prevent it from getting the blood supply it needs to function normally. When the flow of blood is reduced or blocked in the brain, seniors may begin to experience changes in the way they think. Strokes are the leading cause of cerebrovascular damage. Seniors may need to stop smoking, exercise regularly, maintain low blood pressure levels, and stop drinking alcohol to prevent cerebrovascular damage. 

2. Traumatic Injuries 

Some seniors have poor balance and muscle strength, which can lead to slips and falls. Most traumatic brain injuries are due to falls, and this type of injury increases a senior’s risk of developing dementia. The injury could cause your elderly loved one to experience memory loss and changes in vision, speech, and personality. In some cases, these issues last a long time or never go away. To prevent traumatic injuries, you should encourage your loved one to exercise regularly and eat healthy meals to build bone strength. He or she should also get plenty of vitamins. To prevent slips and falls, make sure your loved one’s home is free from clutter and has adequate lighting. 

3. Metabolic Disorders 

Toxins, malnutrition, and other biological conditions can lead to chemical imbalances that cause dementia amongst seniors. These abnormal chemical processes in the body are responsible for the loss of brain function that leads to dementia. If the metabolic disorder is caught early on, it can be treated in most cases. However, when left untreated, the disorders can result in permanent brain damage and dementia. Eating healthy, exercising, avoiding sun exposure, obtaining enough vitamins, and avoiding heavy metal exposure are some of the ways to prevent metabolic disorders, including:

  • Cushing disease
  • Kidney failure
  • Wilson disease
  • Hypoglycemia 

4. Neurodegeneration

The most common biological cause of dementia, neurodegeneration causes brain cells to break down and die. When this happens, seniors can experience a permanent and progressive reduction in mental and physical functions as they age. Neurodegeneration causes loss of nerve cells in a senior’s body that are responsible for connecting the brain to muscles. Blood sugar management is the best way for seniors to prevent neurodegeneration. 

Alzheimer’s disease is a fairly common neurodegenerative disorder in ageing adults, and it could lead to dementia. In Newcastle, NSW, Alzheimer’s care experts are trained in methods that are designed to slow cognitive decline in the elderly. Using a revolutionary program called the Cognitive Therapeutics Method, Alzheimer’s caregivers keep seniors mentally engaged with exciting activities so they can maintain better cognitive health in the golden years.

5. Infections

Viruses and bacteria can destroy your senior loved one’s brain cells and possibly cause dementia. Since the immune system changes as a person ages, it will respond differently to infections and lead to increased signs of agitation, confusion, and withdrawal. When an infection goes unnoticed or untreated for too long, it increases the risk of dementia. You should do whatever you can to help your loved one prevent an infection, such as following a good hygiene regime, monitoring fluid intake, preventing falls, and reporting behavioural changes to a doctor immediately.
