Neurological Awareness
Introduction: You Are Not Alone
Having a loved one facing Alzheimer’s, Parkinson’s, or a similar neurological disease can leave a profound impact on your life. At this point, I want you to know that you are not alone. For many people, hearing the names of these diseases for the first time opens the door to great uncertainty—a language we don’t know, unfamiliar terms… Yet, understanding and communicating are the most fundamental steps of this journey. In this article, we will explore the most basic and reliable concepts regarding our brain and neurological diseases, in language that is both scientific and accessible, with empathy. Knowledge not only empowers you, but also helps you take more peaceful and confident steps in your caregiving journey.
Key Concepts and Definitions
Many of the terms we encounter when discussing the disease are important tools both for understanding the condition and for communicating with the patient and those around us. Here are the most reliable concepts you need to know:
Dementia: An umbrella term that describes a group of symptoms—typically characterized by memory loss, impaired thinking, and a decline in mental abilities severe enough to affect daily life.
Alzheimer’s Disease: One of the most common causes of dementia. It leads to memory loss and, over time, difficulties with speech and problem-solving. It develops as brain cells progressively die.
Parkinson’s Disease: A neurological disorder that occurs due to the reduction of dopamine-producing cells in a region of the brain that controls movement. Tremors, muscle stiffness, and balance problems are among its main symptoms.
Cognitive Functions: The mental abilities that allow our minds to learn, remember, and make decisions. Functions such as attention, memory, and reasoning fall within this scope.
Executive Functions: Complex cognitive processes such as planning, organizing, setting goals, and taking the necessary steps to achieve those goals.
Neurodegenerative Diseases: A general term for progressive diseases that affect nerve cells (neurons). Alzheimer’s and Parkinson’s are the most well-known diseases in this group.
The Course of the Disease and Main Turning Points
The course of these diseases is generally progressive. That is, symptoms may worsen or new problems may arise over time. Early signs of the disease can be so mild that they’re sometimes mistaken for “a natural part of aging.” However, over time:
Early stage: Mild memory difficulties, trouble finding words, and slight setbacks in planning and organizational skills may be noticed.
Middle stage: More noticeable forgetfulness, difficulties maintaining personal care, and increased confusion about place and time can occur.
Late stage: Inability to perform daily activities, failure to recognize close ones, and severe difficulties in communication may appear.
In Parkinson’s, movement disorders like tremor can progress over hours, months, or even years; slowed speech and a reduction in facial expression may also develop.
Brain, Memory and Behavior: Why Do They Change?
Our brain is a complex organ composed of over 100 billion nerve cells. Understanding what and how things change can be enlightening for both the patient’s loved ones and caregivers:
In Alzheimer’s, cell loss starts in the hippocampus, the brain region responsible for memory and learning.
In Parkinson’s, movements are affected due to the reduction of dopamine-producing cells in a region called the substantia nigra.
As the disease progresses, different regions of the brain are affected; this can cause fluctuations in behavior, communication, and mood. Viewing these changes as a result of the illness, rather than taking them personally, can greatly ease the emotional burden.
Most Common Terms and Brief Explanations
Term | Description |
|---|---|
Cognitive Decline | Deterioration in mental functions |
Delirium | Acute disturbance in attention and awareness |
Apathetic | Lack of emotional response and motivation |
Lewy Body Dementia | A type of dementia characterized by the accumulation of proteins called “Lewy bodies” in the brain |
Motor Symptom | Decrease in functions that control movement |
Chorea | Irregular and involuntary muscle movements |
How to Access Reliable Information?
Choosing reliable information among the many resources available can sometimes be challenging. Here are some key points confirmed by current science:
Although the exact cause of these diseases is not fully known, aging and genetic factors are among the most significant risks.
Up to 60-70% of dementia cases are Alzheimer’s (World Health Organization data).
Parkinson’s disease most commonly appears in people over 60, affecting 1-2 out of every 1,000 individuals.
A medical diagnosis should always be made by a physician or neurology specialist.
Currently, there is no medication that completely cures the disease; however, some drugs and care methods can reduce the severity of symptoms.
Understanding Your Feelings: The Normalization Process
Above all, you are not alone in your feelings. A diagnosis of a disease affects not only the patient, but also caregivers and family members. You might experience complex emotions such as guilt, helplessness, anger, or sadness. At this stage, clarifying concepts brings relief not only in practical terms, but emotionally as well. Remember: when you walk forward with patience, open communication and knowledge, the path is difficult but meaningful.
“At times when we are aware of everything, what we do not understand is always the most worrying.”
Family and Social Support: Being Able to Speak and Share
Learning about the basic concepts of the disease doesn’t lighten its entire load, of course. However, as caregivers, you can express what you’re facing first, and this allows you to receive more informed support from those around you. Discussing the medical aspects of the disease with your family or friends makes it easier for them to act more appropriately and empathetically.
Using terms like "cognitive decline" instead of "memory loss" helps avoid misunderstandings.
Describing behaviors as "a result of disease symptoms" rather than "behavioral problems" can reduce social judgment from those around you.
Explaining these basic concepts in an age-appropriate way to children or younger family members helps them be included in the process.
Expert Opinion and Updating Information
Medical science is constantly advancing. At a time when both research and new care models are developing rapidly, following concepts correctly is crucial. You might find it helpful to keep these points in mind:
Take note of every unclear or worrying situation and share it with your doctor.
Follow publications by reliable associations, hospitals, or academic institutions. (For example: Alzheimer’s Association, Parkinson’s Association).
If you do not understand a concept or diagnosis, consult your doctor or a healthcare professional directly.
A Compass for Your Caregiving Journey
Knowing the most basic and trustworthy terms about the disease can offer a small but invaluable compass along your caregiving journey. Of course, unique challenges and days may lie ahead. But knowledge is like a bridge—passed down from generation to generation—that helps you care both for your loved one and for yourself. Sometimes, clarifying just a few words can resolve great uncertainties.
Taking the first step is often the hardest. But understanding and being able to communicate strengthen every step you take together. Remember, you are not alone on this journey; together, we are stronger.
