Is there an elderly person in your family, perhaps your mother, father, or grandparents, who is increasingly forgetful and seems a little anxious? Does it also seem like their legs are dragging along the floor when they walk, and their body seems a little stiff? Do you sometimes hear things like, "Who's that sitting in the chair?" when there's no one else in the room? When you see things like this, you probably feel scared. You might wonder if this is Alzheimer's disease, or something else. Today we're talking about a condition that comes with these symptoms, but is not talked about much in society. That is Lewy Body Dementia.
Simply put, what is Lewy Body Dementia (LBD)?
Okay, let's put it very simply. We have millions of cells in our brain. These cells communicate with each other to control everything we think, do, and do. In a condition called Lewy body dementia (LBD), an abnormal type of protein called Lewy bodies begins to accumulate inside the brain cells. Think of it like a pile of garbage in our house. This buildup of unwanted proteins damages the brain cells and stops them from working properly. This affects memory, thinking, body movements, and behavior.
This is a progressive disease. That is, the symptoms do not come on suddenly. They start gradually and gradually worsen over time. LBD is the second most common type of dementia in adults, after Alzheimer's disease.
The important thing is, this is not just normal aging. This is a medical condition that can be treated and controlled. So it's important to be aware of this.
There are two main types of this LBD.
Yes, there are two main types of LBD. The symptoms of both are very similar. But the main difference is which symptoms start first. Some people start with memory problems first, while others start with things like difficulty walking first.
Let's see what these two types are.
| Type of LBD | Key Feature |
|---|---|
| Dementia with Lewy bodies (DLB) | In this type, problems with thinking and memory start first, much like Alzheimer's disease. Movement problems, such as stiffness and tremors, start later, or may start at the same time as memory problems. |
| Parkinson's disease dementia | In this type, problems with body movement start first. Similar to Parkinson's disease. Things like shaking hands, difficulty walking, and stiffness come first. Memory and thinking problems come later, sometimes up to a year later. |
What could be the symptoms of this disease?
LBD can present with a variety of symptoms. These symptoms do not occur in the same way for everyone. They can vary from person to person. Some symptoms may be present one day and gone the next. That is the nature of the disease.
Let's break these symptoms down into parts.
| Characteristic type | Things to see |
|---|---|
| Cognitive Symptoms | |
| Seeing things that are not there (Visual Hallucinations) | This is a very common feature of LBDs. It makes you feel like you're seeing people, animals, or shapes that aren't actually there. |
| Fluctuations in attention and consciousness | One moment, you may be very alert and talkative, and the next moment, you may be very sleepy and distracted. These states can change even at the same time of day. |
| Memory and decision-making impairments | Forgetting things, having difficulty making decisions, and not being able to find words. |
| Movement Symptoms | |
| Rigidity of the body | Muscles become stiff, making it difficult to bend or straighten the limbs. |
| Tremors | Trembling hands, especially when resting. |
| Slowing of movement | Slow walking speed, dragging feet, frequent falls and loss of balance. Lack of facial expression. |
| Sleep Problems | |
| REM Sleep Behavior Disorder | This is also a very important early symptom. Things like screaming in your sleep, flailing your arms and legs, and falling out of bed. |
| Excessive daytime sleepiness | Feeling excessively sleepy during the day, even though you sleep well at night. |
| Mood & Behavior Symptoms | |
| Depression | Losing interest in anything, always feeling sad and frustrated. |
| Anxiety and restlessness | Feeling afraid and anxious for no reason. |
| Delusions | Believing strongly in things that are not true. For example, someone is secretly trying to poison you or steal your money. |
Why does this disease occur? What are the risk factors?
In fact, doctors still don't know the exact reason why some people develop Lewy bodies in their brains and others don't. However, they have identified some risk factors that may increase the risk of developing the disease.
- Age: This disease usually occurs in people over 50 years of age.
- Family history: If a close relative in your family has had LBD or Parkinson's disease, you may have a slightly increased risk of developing the disease.
- Genes: Certain genes, such as `(APOE)` and `(GBA)`, have been found to increase the risk of developing the disease. However, this does not mean that everyone with those genes will develop LBD.
How does a doctor accurately diagnose this disease?
This is the problem that many people have. There is no single test that can accurately diagnose LBD. Therefore, a doctor will combine various factors, rule out other diseases, and come to an accurate conclusion. This can involve a team of specialists working together.
The diagnostic process usually goes like this.
1. Talking about your medical history: Asking about your symptoms, when they started, and whether anyone in your family has had similar illnesses.
2. Physical and neurological examination: This will check your memory, thinking ability, balance, and muscle strength.
3. Various tests are ordered:
- Blood tests: Check if these symptoms are caused by other medical conditions (e.g. vitamin deficiencies, thyroid problems).
- Brain scans: A CT or MRI scan is used to check for other problems, such as a brain tumor or stroke. Some special types of scans (SPECT, PET) can also provide information about brain function.
- Sleep study: This can help confirm if there are any signs of sleepwalking.
4. Seek help from specialists: Seek help from a neurologist, psychiatrist, or geriatrician.
By combining all of this information, doctors can conclude that this is "probable LBD."
Is there a treatment for this? How can I manage the symptoms?
As sad as this may sound, the truth is that there is no cure for LBD yet, and there is no way to prevent it from developing.
But don't let that discourage you! There are many effective treatments and management methods that can control symptoms and make life much easier for the patient and their family.
The treatment plan is developed based on the patient's symptoms and the stage of the disease.
Medications
The doctor may prescribe various medications to control various symptoms.
- Improve memory and thinking: Medications called `(Cholinesterase inhibitors)` (e.g. `rivastigmine`, `donepezil`) help some people.
- For movement problems: Carbidopa-levodopa, a medication used to treat Parkinson's disease, can help with stiffness and tremors.
- To control hallucinations: Antipsychotics are sometimes used. However, because these medications can have side effects in people with LBD, doctors prescribe them with great caution.
- For depression: Antidepressants.
- For sleep problems: Medications like `(Clonazepam)` and `(melatonin)`.
Therapies and Support
Like medication, these treatments also help make life easier.
- Occupational therapy: Helps you perform daily tasks (eating, dressing) independently and safely.
- Physical therapy: Helps improve body strength and balance, making walking easier, and reducing falls.
- Speech therapy: Helps with speech and swallowing difficulties.
In addition to all of this, it is very important to maintain a calm, consistent routine . This can reduce the patient's anxiety and restlessness.
When is it best to see a doctor?
If you or someone in your family, especially an elderly person, starts seeing things that aren't there (hallucinations), along with any changes in memory, gait, or behavior, please don't ignore it. Be sure to see a doctor and talk about it.
If you already know you have LBD, it is important to see your doctor for regular checkups. If you notice any changes in your symptoms or new symptoms, you should tell your doctor.
Things to know about living with this disease
Because this disease is progressive, over time, it can become difficult for the patient to make decisions on their own and perform daily tasks. Therefore, it is very important to talk about and plan for the future while the patient is still mentally alert.
On average, a person with LBD is said to live between 5 and 8 years after being diagnosed, but this varies greatly from person to person. Some people live much longer than that.
Living with this disease is a challenge for both the patient and the family who cares for him/her. But remember, you are not alone. With the right medical care, support, and awareness, this journey can be made easier.
Take-Home Message
- Lewy Body Dementia (LBD) is not just about forgetting things. It is a complex condition that affects everything from memory, movement, sleep, and behavior.
- Hallucinations and acting out dreams can be the main and early symptoms of this disease.
- Although this disease cannot be completely cured, there are many medications and treatments that can control the symptoms and make life easier.
- If you or a loved one is suffering from these symptoms, don't panic and see a doctor without delay. The sooner the disease is diagnosed, the easier it is to manage.
- Support for the patient and caregivers is very important. Maintaining a calm environment and a consistent routine can go a long way in controlling symptoms.
