Is your loved one experiencing memory loss? Let's talk about early dementia
Table of Contents ▾

Have you ever noticed that an elderly person, like your mother, father, or grandmother, forgets things little by little? For example, they forget where they put their glasses , or they don't immediately remember the name of someone they know. Although we think these things are normal as we get older, sometimes they can be the first signs of a serious illness. That's why we're talking about this condition today, called dementia . This is a very sensitive topic, so let's talk about everything simply and in an understandable way.

What exactly is Dementia?

Simply put, dementia is a serious condition that gradually impairs the functioning of our brain . It is not just forgetfulness. It directly affects the cognitive functions of our brain.

Think of our brain as a very complex, powerful computer. This computer controls everything about us. When dementia develops, it's like important programs in this computer stop working.

The main things affected by this are:

  • Memory: Forgetting things, especially recent ones.
  • Thinking: Inability to think clearly and reason.
  • Learning: Difficulty learning something new.
  • Problem Solving : Inability to find solutions to everyday problems.
  • Language and Speech: Difficulty finding words when speaking, inability to carry on a conversation.
  • Planning : Inability to plan and carry out work in an orderly manner.

In addition, there may be changes in a person's personality and behavior . A person who was previously very calm may suddenly become angry and agitated. Usually, doctors do not label this as dementia unless these symptoms persist for at least six months.

Is all forgetfulness dementia?

This is the biggest question that many people have. Some people are afraid, "Am I forgetting things now? Am I going to develop dementia?" In fact, it's normal for our brain processes to slow down a bit as we age. While it can be a big problem, it's not so much that it prevents us from doing our daily activities.

But dementia is something different. Let's understand this difference clearly.

Characteristic Normal aging In Dementia
Forgetfulness Things like where the mirror was or someone's name can be temporarily forgotten, but then remembered. Entire events that happened recently (e.g., what you did yesterday, what you talked about this morning) are forgotten and not remembered later.
Daily work Even though you may need help sometimes, you can do your work alone. Even simple tasks like cooking, getting dressed, and managing money become difficult.
Directions and locations You can get lost when you're walking on an unfamiliar road. You can get lost even on a well-known and familiar road.

What causes dementia?

There is no single cause of dementia. There can be many causes. The best part is that some of these causes are reversible .

Curable causes:

Irremediable causes:

The most common and most common of these is Alzheimer's disease . This is the leading cause of dementia among older adults. It is characterized by the gradual destruction of brain cells over time.

An intermediate condition called MCI (Mild Cognitive Impairment)

Now let's talk about a slightly more complicated, but very important condition: Mild Cognitive Impairment , or MCI .

Simply put, MCI is an intermediate condition that is more forgetful than normal aging, but not as severe as dementia.

A person with MCI has memory problems, which are noticeable to them and to their loved ones. However, they can still perform their daily activities without much difficulty. This is the main difference between dementia and MCI.

MCI does not mean that everyone will develop dementia. But it is a risk factor. People with MCI are more likely to develop Alzheimer's disease than others. Therefore, it is very important to seek medical advice if you have these symptoms.

There are also types of MCI. The type that mainly affects memory is called "amnestic MCI." Amnesia means loss of memory, which is where the name comes from.

What should we do? When should we see a doctor?

If you or someone close to you feels like they have the following symptoms, please don't be afraid or panic, but talk to a doctor.

  • If memory loss is affecting daily life (e.g. forgetting to pay bills, forgetting to take medication).
  • If the ability to plan or solve problems is reduced (e.g. forgetting the order in which a dish is cooked).
  • If you have difficulty doing a routine task (e.g., not being able to find the items you need at your usual supermarket).
  • If you are confused about time or place.
  • If you have difficulty finding words when speaking or have problems when writing.
  • If things are always going missing and you can't find where they are.
  • If your decision-making ability has decreased.
  • If you stay away from social activities.
  • If you see clear changes in mood and personality.

Remember, seeing a doctor early can be a big help. It may be that the cause is treatable. Otherwise, if it's a condition like Alzheimer's, early detection can help the patient and family plan for the future, get the support they need, and maintain the patient's quality of life as best as possible.

💡 Take-Home Message

  • Dementia is not a normal part of aging; it is a brain disease.
  • Not all forgetfulness is dementia, but if your memory loss is so severe that it affects your daily life, don't ignore it.
  • Some causes of dementia (such as vitamin deficiencies and infections) can be treated, so it's important to see your doctor as soon as possible.
  • MCI (Mild Cognitive Impairment) is a warning sign. Being aware of this can help you plan for the future.
  • If someone close to you has these symptoms, treat them with love, patience, and understanding. Help them get referred to a doctor.
