What is dementia? Symptoms, stages, types, and more

Various symptoms of cognitive disorders such as dementia, amnesia have been described. It is a symptom of many mental illnesses and disorders.

Dementia is a term that refers to symptoms that affect memory, communication and thinking. The incidence of dementia increases with age but is not as stable.

Trusted sources include types and causes of dementia:

This is the name of mental illness

  • Alzheimer’s disease
  • vascular dementia
  • Dementia Lewy bodies linked with Parkinson’s disease.
  • frontotemporal dementia
  • mixed dementia

Scientists call this Alzheimer’s disease and Alzheimer’s dementia.

This article discusses the possible causes of dementia, the different types of treatment, and treatment options.

People with dementia

Symptoms of dementia depend on the type of person, but usually include:

  • Problems with memory
  • Ask the same questions again and again
  • Difficulty finding or understanding words
  • It means you are in a strange place.
  • Problems with large numbers
  • Take it slow and don’t let go.
  • Difficulty making decisions and completing tasks
  • The mood has changed
  • personality and behavior changes
  • Sleep disorders
  • Changes in social consciousness, such as negative shocks.
  • A fictional trend

Symptoms become more pronounced over time. A person may have some symptoms themselves, but family members or caregivers may have other symptoms.

Dementia  disease

A reliable report by the World Health Organization (WHO) broadly divides it into three: early, intermediate and advanced.

First phase

A person in such a condition does not develop dementia. You want to say:

  • rather forgetful
  • They take their time.
  • I feel lost in familiar surroundings

Middle phase

At this stage, symptoms are more pronounced and include:

  • Forget modern nouns and verbs
  • Feel lost at home.
  • communication problems
  • Behavior modification.
  • Always ask questions

Last phase

Continuous support is needed during this period as the symptoms and problems are very strong. Individuals can:

  • You need to know where they live.
  • I don’t know when it happened
  • It’s hard to get to know your loved ones
  • Walking becomes difficult.
  • Experience behavioral changes with aggression.

Types of dementia

There are several types of dementia. This is the name of mental illness

Alzheimer’s disease

Alzheimer’s disease is the most common cause of dementia and is a reliable condition in 70-80% of cases. In Alzheimer’s disease, “plaques” and “bumps” form in brain cells. Both are caused by changes in the protein.

Short-term memory can cause difficulty finding and remembering words, as well as difficulty seeing three-dimensional objects.

Dementia with Lewy bodies

Lewy body dementia occurs when a disorder called Lewy bodies develops in the brain. These brain changes are linked to a protein called alpha-synuclein.


Early stages may include changes in alertness, hallucinations, and difficulty making distant decisions. Short-term memory loss is likely to be less severe than Alzheimer’s disease.

Although doctors may think of Parkinson’s disease as a behavioral disorder, symptoms of dementia can also occur.

Frontotemporal dementia

It also affects the front and sides of the head. This happens when brain cells die due to the growth of protein clusters.

Depending on which part of the brain is affected, a person may have difficulty walking, talking, communicating, or both.

Huntington’s disease

Huntington’s disease is an inherited genetic disease. The main symptom is uncontrolled movements, but it can also be disorientation.


Early symptoms include difficulty focusing on a reliable source, irritability, and confusion. and discomfort. This person may have difficulty with organization, multitasking, and decision making. These symptoms appear before motor changes.

Mixed dementia

When this happens, it turns out that the person is active in two or three genres at the same time. For example, a person may have Alzheimer’s disease and a vascular disease at the same time.


Early symptoms of dementia vary by type, but usually include:

  • to forget
  • mood
  • anxiety, anger or depression
  • hard to find the right words
  • not listening
  • cowardice
  • repeat a speech or movement
  • Difficulty following or retelling the story
  • Difficulty completing daily tasks
  • disorientation
  • Difficulty adapting to change
  • put everyday objects in unusual places

Cause of dementia

Some forms of dementia, such as Alzheimer’s disease, result from the gradual death of brain cells and nerve cells.

However, dementia can be caused by head trauma, stroke, brain tumors, and other complications. For example, a stroke can prevent blood and oxygen from reaching brain cells, damaging them and causing death. A blow to the head can directly damage brain cells.

Severe types of brain injuries (especially if they are common in certain sports) can increase the risk of developing food cravings later in life.


Major factors and conditions with similar symptoms include:

  • use of certain medications
  • Certain diseases, such as HIV and neurosyphilis
  • depression
  • vitamin B12 or E deficiency
  • thyroid problems

Dementia test

Assessments often contain many questions and challenges.

Cognitive dementia test

Scientists in the 1970s developed the standard test that doctors use today. Doctors may ask questions such as:

  • How old are you?
  • What time is the closest?
  • What is your address?
  • How old are you now?
  • When is your birthday?

Doctors may also consider monitoring family members and caregivers.

If the results show memory loss, your doctor may order blood tests and a CT scan of your brain to investigate further and reveal other possible causes.

Another test, called a psychological test, has been in use since the 1970s and measures:

  • express time and place
  • word memory
  • language proficiency
  • Attention and planning
  • presentation ability

This helps diagnose dementia associated with Alzheimer’s disease. It can also measure its severity and determine whether drug treatment is appropriate.

Mini cog test

Your doctor may also perform a test called the Mini-Cog test. It contains the following steps:


The therapist takes three words from a group of words, such as “banana, sunrise, chair,” and has the person repeat them. This allows three tests.

If the person is unable to do this, the doctor asks them to draw a clock face, fill in the numbers and set the hands to a specific time. The person must do this within three minutes.

If the person cannot complete the hour task in the allotted time, the therapist asks them to recall and repeat three words from the previous task.

This goes up to 10 points. If your score is below 3-4, your doctor will likely stick you to dementia.

Treatment of dementia

There is currently no cure for most forms of dementia because the death of brain cells cannot yet be reversed. But treating the symptoms can help.


Certain medications can help relieve Alzheimer’s symptoms. Three drugs called cholinesterase inhibitors have been approved for use in the United States. you:

  • Donepezil (Aricept)
  • Galantamine (Riminil)
  • Rivastigmine (Exelon)

Cholinesterase inhibitors can also help control the behavioral symptoms of Parkinson’s disease.

It is also possible to use the NMDA receptor blocker memantine (Namenda) alone or with a cholinesterase inhibitor.

If the symptoms are due to injury, medication or vitamin deficiency, further damage can be a hindrance.

Other care form

Some lifestyle strategies that can be very helpful for dementia include:

  • Follow a healthy diet
  • Play regularly
  • Participates in all medical interviews
  • Take the medicine as prescribed
  • He always sleeps.
  • is a safe existence.
  • If necessary, it is supported by relatives and carers.

Prevent dementia

Most dementias cannot be prevented. However, the QUITRUSTED source suggests that you do the following at your own risk;

  • Play regularly
  • Avoid smoking cigarettes
  • Limit alcohol consumption
  • Maintains average weight.
  • Follow a healthy diet
  • Look for conditions such as high blood pressure, high cholesterol and high blood sugar.

Wearing a protective helmet during contact sports also reduces the risk of repetitive head injuries, which can be a risk factor for dementia.


Dementia is the term for symptoms that affect memory, thinking and behaviour. It is part of Alzheimer’s disease and can occur with some emotional disorders such as Huntington’s disease and Parkinson’s disease.


Symptoms often get worse over time and are no longer worrisome. Medicines can treat some health problems, but sometimes a person may need full support.
