Type of Dementia

Dementia is not equal to Alzheimer’s disease

As we grow older, the aging of brain cells causes the elderly to become forgetful, such as often forgetting to take things out, forgetting to turn off the gas, unable to remember the names of friends, etc., and even begin to doubt whether they are suffering from dementia.

However, dementia is not the same as normal aging. It not only causes people to completely forget what they have done, but also causes problems such as inattention, lack of judgment, and deterioration of language skills.

Let us take you to understand the common symptoms and types of dementia, and explain the symptoms that may occur in different dementia patients according to the stages of dementia.

What is dementia?

Dementia is a disease of persistent cognitive decline caused by brain neurological diseases, systemic diseases, or due use of addictive drugs. Affected patients will face a comprehensive loss of mental abilities, such as thinking ability, judgment, memory, sense of space, and rationality.

Dementia usually occurs in people over age of 65, but very few patients will develop dementia around the age of 30-50, also known as “young-onset dementia”.

Is dementia Alzheimer’s disease? 5 types of dementia

Many people think Alzheimer’s disease is equivalent to dementia. In fact, it is only one of its dementias. Others include vascular dementia, Lewy body dementia, and frontotemporal dementia. and dementia caused by other factors. The following will explain the causes and symptoms of the 5 types of dementia in detail:

  1. Alzheimer’s disease
    In 1907, by a German psychiatrist Alois Alzheimer published the case of “senile dementia”, and later named the disease after him.When β-amyloid peptide is excessively deposited in the brain, it will activate the immune cells Microglia and the signaling regulatory cells Astrocyte in the brain, causing inflammation. The reaction eventually leads to the necrosis of brain nerve cells, leading to Alzheimer’s disease. Common symptoms of Alzheimer’s patients are memory loss, hallucinations, and impaired judgment. In the later stages of the disease, patients may also experience Parkinson’s symptoms, such as body stiffness, hand tremors, and unsteady walking.
  2. Vascular dementia
    Vascular dementia stems from cerebral apoplexy or chronic cerebrovascular disease, resulting in poor blood circulation in the brain, which in turn leads to brain cell damage. Generally speaking, about 5% of patients who have had a stroke will suffer from vascular dementia. Once the disease occurs, the patient’s cognitive function may suddenly deteriorate, accompanied by slow movement, unsteady gait, emotional ups and downs or depression and other mental illnesses.
  3. Dementia with Lewy bodies, DLB
    When the protein α-synuclein is abnormally deposited in the brain, it may lead to degeneration of cognitive function and suffer from dementia with Lewy bodies. Dementia with Lewy bodies tends to occur in the elderly over 70 years old, and is the second most common degenerative dementia. In addition to cognitive dysfunction, the common symptoms may also appear Parkinson’s symptoms, including hand tremors, difficulty walking, stability to balance their body, unexplained falls, etc., and even obvious visual and auditory hallucinations, emotional instability or delusions and other mental symptoms.
  4. Frontotemporal disorders, FTD
    When the frontal and temporal lobes in the brain gradually shrink, the cranial nerves will degenerate, leading to frontotemporal dementia. Among all patients with frontotemporal dementia, about 40% have a family history of dementia. 10% are dominant inheritance; its prevalence is second only to Alzheimer’s disease and Lewy body dementia, and it usually occurs in middle-aged and elderly people over the age of 50, and it is one of the slowly progressive neurodegenerative diseases. In addition, unlike Alzheimer’s disease, where memory impairment is the main symptom, emotional and behavioral abnormalities characterize frontotemporal dementia (such as talking all the time in a quiet place), executive function impairment, or language barriers. It is often not easy to distinguish from mental illness.
  5. Dementia due to other factors
    Some dementias are caused by specific reasons, which may recover after treatment. The causes of this type of dementia can be divided into the following 4 types:
    1. Abnormal metabolism: such as hypothyroidism, electrolyte imbalance, etc.
    2. Nutritional disorders: such as lack of vitamin B12, folic acid and other nutrients.
    3. Intracranial lesions: such as brain tumors, normal pressure hydrocephalus, brain trauma, etc.
    4. Central nervous system infection: such as syphilis, AIDS, etc.
    5. Poisoning: such as long-term drug abuse, alcoholism, heavy metal poisoning, etc.


Stages of dementia symptoms: mild cognitive impairment, early, middle and late stages of dementia

According to dementia stages, it can be divided into mild cognitive impairment, early stage, middle stage, and late stage of dementia. The degeneration time of each patient is different. Sometimes the symptoms will improve, and sometimes they will suddenly worsen.

From mild cognitive impairment to advanced stage, the average course of the disease is about 8-10 years, but the degeneration time of each person is unknown. It may be as short as 2 years, and it can last as long as 20 years.

The following describes the development of each dementia course:

  1. Mild cognitive impairment: It is a transitional stage from normal aging to dementia, and about 10%~15% of mild cognitive impairment will develop into dementia every year. Patients may experience symptoms of mild forgetfulness and trouble with more complex tasks, but simple daily tasks are not affected.
  2. Early stage of dementia (mild): Because the symptoms are quite mild, the appearance and behavior of the patient are no different from ordinary people, so they are often ignored and delay seeing a doctor. In the early stages of dementia, patients usually cannot remember what happened recently, and they ask their relatives and friends repeatedly, but they can remember the memories of their youth clearly. In addition, patients’ judgment and work ability may gradually weaken, and they cannot handle more complex things in daily life, such as deposits and withdrawals in the bank.
  3. Middle stage of dementia (moderate): In the middle stage, the patient’s judgment and living ability will gradually decline, and it will become more difficult to deal with daily affairs. Common symptoms include inability to distinguish seasons, failure to recognize familiar relatives and friends, insomnia, abnormal mood swings, personality changes, and even basic living abilities such as self-cooking, laundry, and personal cleaning and sanitation may cause problems.
  4. Late stage of dementia (severe): Patients at this stage have almost complete loss of memory, can’t remember important things in life, day and night are reversed, can’t communicate with family members in a simple way, can’t distinguish the environment at home, and even forget who they are. More seriously, they lack judgment and understanding. In addition, patients with advanced dementia may also suffer from degeneration of limb muscle strength due to long-term lack of exercise, need to stay in bed for a long time, and completely rely on the care of family members.
