What is Dementia?

Dementia isn’t a or disease, but a conglomeration of symptoms. You might associate dementia with memory loss. That is one of the signs; however, there are many other symptoms of dementia. It impacts how a person functions on a daily basis and severely affects their cognitive functioning. Dementia can impact a person’s executive functioning skills, motor function, and cause the person to have personality shifts. A person suffering from dementia may be moody and engage in unpredictable behavior. They might display strange thinking or act erratically.


Memory loss or impairment is one of the most commons symptoms of dementia. A person who has the condition will struggle to remember common words for objects or the names of people they love. It can be disturbing to the individuals loved ones to see them struggle to recognize those who are close to them. Here are some of the other symptoms that a person with dementia may experience.

Symptoms of Dementia

  • Memory loss
  • Trouble communicating with others
  • Difficulty finding the right words for everyday objects
  • Forgetting the names of important people
  • The trouble with logical reasoning or solving problems
  • Difficulty handling complicated tasks or instructions
  • Confusion and disorientation

You can still treasure the memories you have together.


Causes of Dementia

Head Trauma

Dementia and traumatic brain injury are linked. Head injuries can contribute to or cause dementia in people. Extensive research has been conducted on the link between dementia and TBI, and there is a correlation between the two conditions. People who have had a traumatic brain injury are at severe risk for developing Alzheimer's disease or another condition that has dementia as a symptom.

Alzheimer’s Disease

One of the most common causes of dementia is Alzheimer's disease. In people over 65 Alzheimer’s is the most likely cause of dementia. Alzheimer’s doesn’t have a cure, but there are some things can slow down the progression of the illness.

Vascular Dementia

Vascular dementia is the second most common cause of the condition. It occurs when blood vessels in the brain become damaged. It occurs most frequently in elderly populations. However, it can happen to younger people as well. Strokes can sometimes cause vascular dementia.

Treatable Conditions That Cause Dementia

Immune Disorders and Infections

Fevers and immune disorders can cause dementia-like signs. When your body is trying to fight disease, it might react by creating these symptoms. Multiple Sclerosis is an illness where the body's immune system attacks nerve cells. People with MS sometimes experience symptoms that resemble dementia.

Metabolic Issues and Endocrine Problems

Individuals who have thyroid problems, low blood sugar (hypoglycemia), and those people who have too much sodium or calcium can experience dementia-like signs. People who have difficulty with vitamin B-12 absorption may develop symptoms that resemble dementia. They may also undergo severe personality changes.

Nutritional deficiencies are another cause of Dementia. People who don’t drink enough water and become dehydrated can experience symptoms that are similar to dementia. When an individual doesn’t get enough thiamine (vitamin B-1), they can have dementia-like symptoms. People who are alcoholics are commonly deficient in B-1. When you don’t get enough vitamins B-6 and B-12 from food or supplements, this can cause dementia-like symptoms.
