Explain The Different Types Of Dementia?

Types of Dementia

There is a lack of awareness in society about dementia. We will also give information about the Different Types Of Dementia

Dementia or dementia is a problem that occurs in old age. It is not a disease, but the name of the symptoms arising from changes in the behavior of a person after damage to the brain or brain. Dementia patients become mentally weak, not physically. He has to take the help of others even to complete the daily tasks.

Dementia is not a disease in itself. This problem occurs when there is damage to the brain due to Alzheimer’s / tension/depression/ stress or any shock. Alzheimer’s is considered the leading cause of dementia or dementia.

What Is Dementia?

The word Dementia / Dementia is made up of ‘De’ meaning without and ‘Mentia’ meaning Mind.  Most people understand that dementia is the name of the problem of forgetting small things. But forgetting things or memory loss is not the only symptom.

The problem of dementia is much more serious than this. There can be many other worrying symptoms as well. These symptoms also affect the patient’s everyday life. These problems increase with age.

Many people confuse dementia with dementia or insanity. But it is very important to know that having dementia does not mean that the patient is mentally retarded. This is not even typhus, hysteria, or delirium. Dementia does not even mean insanity. Dementia is Amnesia, memory loss, not forgetting things.

Additionally, the individual’s capacity for independence in everyday activities must be impaired. These are some of the most common Types Of Dementia and their causes.

Different Types Of Dementia

The symptoms and severity of dementia depend on what type it is. Some dementias are diagnosable and some are still incurable. These are the different kinds of dementia that can be treated:


This is the most common type of dementia. Alzheimer’s is caused by changes in the brain. Due to chemical reactions in the brain, certain proteins are produced, which increases the size of the veins. While the size of the patient’s brain decreases. Alzheimer’s is the main cause of dementia. It is responsible for about two-thirds of dementia cases.

Alzheimer’s is a progressive disease described as the deposition and plague of proteins in the brain. Scientists are still striving to conclude what results in Alzheimer’s. Advanced age, family history, and lifestyle factors, like smoking, affect a person’s risk of developing Alzheimer’s.

In Alzheimer’s disease, there is brain damage – neurofibrillary tangles and beta-amyloid plaques are seen in the brain, and the brain begins to shrink. Signs emerge in a person due to brain injury. Initially, these symptoms are mild and many times people do not pay attention to them.

The most common early symptom is memory problems. For this reason, this disease is also known by many as “amnesia”, “memory loss” and “memory problem”. There are many other symptoms in the beginning, such as Different Types Of Depression Disorders, disinterest, lack of proper sense of time and place, etc.

Alzheimer’s disease is progressive, and the damage to the brain that occurs in this progresses over time. The symptoms also become severe. The person starts having problems with all the work. In the late stages of the disease, the person remains in bed for most of the time and becomes completely dependent on others.

Lewy Bodies Dementia

This is another kind of dementia that is caused by the accumulation of a protein called Alpha-Synuclein in the cortex. Due to this dementia, the patient may have complaints like loss of memory, confusion. Apart from this, problems in sleeping, confusion, inability to keep balance in the body and problems in going to the bathroom, etc.

Lewy body dementia, named after Frederick H.  Levy, who first described the deposits in the early 1900s, is characterized by deposits of the protein alpha-synuclein inside brain cells.  While many symptoms of Lewy body dementia are similar to those of Alzheimer’s, three symptoms distinguish it from other Types Of Dementia: vivid hallucinations, different levels of consciousness or alertness, and severe sleep disturbances.

Parkinson’s Dementia

This disease is neurodegenerative. This is a condition in which the nervous system is damaged. This loss can later lead to dementia. Later on, it can also take the form of Alzheimer’s. The patient of this disease becomes unable to drive and make even small decisions.

Parkinson’s disease is the progressive deterioration of nerve cells in the brain that produce the important brain chemical dopamine. Dopamine functions as a chemical messenger in the brain, corresponding to smooth and balanced muscle movement. Without dopamine, the brain is unable to communicate, leading to a loss of its ability to control body movements.

In its advanced stages, Parkinson’s can affect cognitive functioning, causing problems with memories, reasoning, problem-making, and problem-solving, and depression. Dementia occurs in approximately 20% to 60% of patients with Parkinson’s disease.

Mixed Dementia

In this Types Of Dementia, the patient catches many diseases at the same time, such as Alzheimer’s as well as the problem of Vascular Dementia. There is also the possibility of having many other Types Of Dementia in this problem.

Mixed dementia implies the diagnosis of two or three types ensuing together. For example, a person may show both Alzheimer’s disease and vascular dementia at the same time.

Frontotemporal Dementia

With this Types Of Dementia, there is a change in the personality and conversation as well as the behavior of the patient suffering from this type of dementia. He starts having problems with understanding and speaking his language.  This disease is usually the result of some other disease. These diseases mainly include Pick’s Disease and Progressive Supranuclear Palsy.

Frontotemporal dementia ( FTD ) is characterized by atrophy, or wasting, of the front and temporal lobes of the brain in the absence of Alzheimer’s. It usually precedes Alzheimer’s disease with onset occurring between the ages of 35 and 75.

It evolves more quickly than Alzheimer’s and has a lower life expectancy. There may be a genetic link to FTD but scientists are still uncertain of the exact cause. FTD usually presents with behavioral changes, usually in the form of inappropriate social or personal conduct. Problems with speech, called aphasia, are the other main manifestation of FTD.

Huntington’s Disease

Huntington’s disease is an inherited disease that usually occurs in a person’s 30s or 40s. It is characterized by uncontrolled movements, emotional disturbances, and mental decline.

As with Huntington’s disease, progressive mental decrease with consequential dementia may be the early sign of illness. A child with a parent diagnosed with Huntington’s gene has a 50% chance of developing the disease.


There is an urgent need to include dementia as national health and social priority with provisions to identify and provide adequate services for its treatment. We can say that dementia disease is affecting mostly older people but aging is not the common reason for this.


What kind of disease is dementia?

Dementia is not the name of a single disease, but the name of a group of symptoms. These can damage the brain and because our body is controlled by our brain, due to dementia, the person suffering from it is not able to do his regular work properly. His memory may also be weak.

What is the cause of Alzheimer’s disease?

Alzheimer’s can be caused by a previous head injury. Alzheimer’s can be a complication due to a disease like a sleeplessness in sleep. You can also get Alzheimer’s disease due to genetics i.e. family history.
