Have you ever noticed that someone in your family, perhaps your mother, father, or spouse, has suddenly changed? They may be acting more stubbornly than before, slurring their words, or losing interest in things... While many people think this is a normal part of aging, sometimes it can be a sign of a more serious condition. Today we're talking about one such condition, which is Frontotemporal Dementia.
What is Frontotemporal Dementia (FTD)?
Simply put, this is a disease that affects our brain. Think of our brain as a big control center. It is the various parts of it that control everything from our behavior, speech, and planning.
In FTD, two frontal lobes of the brain are primarily damaged.
1. Frontal lobes: These are located behind the forehead. They are like the CEO of our control room. They control our personality, decision-making, emotional control, and how we behave in society.
2. Temporal lobes: These are located near the ears. They are like our language and memory areas. This part helps us understand words, speak, and remember things.
In FTD, the nerve cells (neurons) in these two areas are damaged and gradually die. As the nerve cells die, those areas of the brain shrink, like a balloon being deflated. As a result, the functions controlled by those areas are gradually lost. This is a progressive disease that gets worse over time.
What are the main types of FTD?
FTD does not affect everyone in the same way. Symptoms vary depending on which part of the brain is damaged. Accordingly, there are several main types.
| Type | Main visible features |
|---|---|
| Behavioral variant (bvFTD) | This is the most common type. Personality and behavior change completely. They do and say things that are not socially acceptable. They don't understand that what they are doing is wrong. They lose their empathy. |
| Speech difficulties (Primary Progressive Aphasia - PPA) | The main problem here is related to language. When speaking, it becomes difficult to find words, words get mixed up, and it is impossible to understand what is being said. Over time, the ability to read and write is also lost. |
| Types that cause difficulty in movement | This includes conditions like Corticobasal degeneration and Progressive supranuclear palsy. Problems with body movement occur. For example, difficulty using one side of the body, loss of balance when walking, and difficulty moving the eyes. |
| FTD and other diseases together (such as FTD-ALS) | Sometimes FTD can occur together with other neurological diseases, such as ALS, which weaken the muscles. In this case, changes in behavior and speech, along with rapid muscle weakness, are also seen. |
What are the common symptoms of FTD?
Although symptoms vary from patient to patient, there are a few common things that can be seen. These can give you an idea of the condition.
| Symptom | A simple explanation |
|---|---|
| Loss of interest (Apathy) | They lose interest and motivation to do anything. They withdraw from society and don't even think about their own cleanliness. |
| Inappropriate social behavior | When speaking, there is no 'filter'. They say whatever comes to mind, without thinking about whether it will hurt others' feelings. They may be tempted to do risky things. |
| Loss of empathy | They become unable to understand other people's feelings, such as sadness or happiness. They may act as if they have no heart. |
| Changes in eating habits | Eating a lot of food at once, especially sweets. Some people are tempted to eat things they shouldn't eat (e.g., dirt, paper). This is called Pica in medical terms. |
| Repeating the same thing | Repeating the same word or sentence over and over again. Or performing the same action (e.g., clapping). |
| Planning difficulties | It becomes difficult to plan work, solve problems, and make decisions. |
The important thing is that these symptoms are not very obvious at first, but they gradually become worse over time.
Why does FTD develop? Who is at risk?
Researchers are still not sure what exactly causes FTD, but two main factors are being considered.
- Protein deposits: It is believed that abnormal proteins accumulate inside nerve cells in the brain, damaging the cells and causing them to die.
- Genetic influence: About a third of people with FTD have a family history of the condition. This means that if someone in your family has had the condition, you are at risk of developing it too. This may be due to a change in your genes.
Additionally, some studies have shown that a previous severe head injury (traumatic brain injury) may also be a risk factor.
How does a doctor diagnose FTD?
Diagnosing FTD can be challenging, as the symptoms can be similar to those of other mental illnesses (such as depression) or Alzheimer's.
Therefore, the doctor will ask you and the patient a detailed question about your symptoms. After that, they may do some tests to make sure there are no other medical conditions.
- Blood tests: Check for other medical conditions.
- Brain imaging tests: Tests such as MRI, CT scan , or PET scan can be done to see if the frontal lobes of the brain have shrunk.
- Cognitive testing: You are given several questions and activities that measure things like memory, attention, and problem-solving ability.
- Genetic testing: Can be done if necessary depending on family history.
After looking at all of this, the doctor comes to the conclusion that it is FTD.
What are the treatments for FTD?
The sad thing is that there is no cure for FTD yet. However, there are treatments that can help manage the symptoms and maintain the patient's quality of life for as long as possible.
- Medication: Medications such as Selective Serotonin Reuptake Inhibitors (SSRIs) may be prescribed to control behavioral problems (anger, impulsivity). Other medications may also be prescribed for mental disorders.
- Therapeutic treatment:
- Speech therapy: If you have difficulty speaking, this can help you practice other ways to communicate.
- Physical therapy: If there are mobility problems, exercise is recommended to maintain balance and strength in the body.
- Assistive devices: If you have difficulty walking, you can use things like a walker or wheelchair.
All of these treatments are determined based on the patient's condition and symptoms. Therefore, it is very important to talk to your doctor and follow his or her instructions exactly .
What to expect when living with FTD?
This is a very challenging journey for both the patient and the family caring for them. As the disease progresses, the patient may become unable to perform daily activities on their own. Therefore, full-time care may be required.
If you are diagnosed with this disease in its early stages, there is a very important thing you can do. That is to make decisions about your future, communicate them to your loved ones, and have legal documents prepared.
It's hard to have this kind of conversation. But it can prevent the family from having to worry about "what would he want?" after the disease has progressed to the point where he can't make decisions.
Although the average life expectancy after a diagnosis of FTD is around 7-13 years, these statistics do not apply to everyone. This can vary greatly from person to person. The best person to know exactly what your loved one's condition is their doctor.
Direct death from FTD is rare, but complications such as pneumonia caused by swallowing difficulties can be life-threatening.
Take-Home Message
- Frontotemporal Dementia (FTD) is a disease that primarily affects behavior, personality, and language , rather than memory loss.
- This is a condition that gradually worsens over time.
- Although there is no complete cure, there are treatments that can manage symptoms and provide relief to the patient.
- If you notice an unexplained, persistent change in the behavior or speech of someone in your family, see a doctor immediately for advice.
- It is very important to diagnose the disease at an early stage, plan for the future, and get the necessary support for the patient and family.
