Shall we talk about brain diseases? Are you aware?

Have you ever wondered how much work our brain, which may seem small at first glance, does? This amazing organ controls everything we think, do, and feel. But sometimes, the brain can also develop various diseases . Today, we are going to talk about such diseases that affect the brain, or (Brain Diseases) . It is very important to be aware of this, because then we can quickly identify these conditions and get the necessary medical advice.

Simply put, the brain is like the main control center of our body. Not only our growth and development , but also all the functions of the body are regulated by the brain. Everything you think, everything you feel, everything you do starts from there. The brain is part of our nervous system . It is like the motherboard of a computer. It is through a network of nerves that information about our body and the outside world is carried to the brain and spinal cord . The brain processes these signals and sends the responses out through the spinal cord along the nerves. So, there are many diseases that affect this brain. These can change a person's behavior, personality, ability to understand information, and ability to perform daily tasks.

What are the types of brain diseases?

There are actually hundreds of different types of brain diseases. Some are very rare. But let's talk about a few of the main categories that we should all be aware of.

Autoimmune Brain Diseases

This sounds a little strange, doesn't it? Autoimmune is, quite simply, when our body's own defense system, the soldiers that are supposed to protect us from disease, attacks parts of our own brain . They think it's an enemy from outside.

• A good example of this is Multiple Sclerosis (MS) . Just like an electrical wire has a plastic covering over it, our nerve cells also have a protective covering. In MS, this covering is damaged in the nerves in the brain, spinal cord, and eyes.
• There are also other autoimmune brain diseases that are similar to MS, but are slightly less common.
• Some other diseases, such as autoimmune encephalitis, can cause swelling in the brain, resulting in memory loss and involuntary jerking of the limbs.

Epilepsy

Epilepsy , or as some people call it, 'having a fit', is a tendency to have repeated seizures . A seizure is like an electrical storm in the brain.

• This usually involves loss of consciousness and uncontrollable body movements.(convulsions) .
• But some seizures are not as severe. They may be a mild loss of consciousness or the uncontrolled movement of just one part of the body.

Infections

Infections occur when various types of germs, such as bacteria and viruses, enter our brain or the protective membranes surrounding the brain.

• Meningitis is an infection of the protective membranes surrounding the brain. It often causes symptoms such as headaches, confusion , and a stiff neck.
• Sometimes, a spinal tap is needed to determine exactly what germ is causing the infection. Only then can the right antibiotics be given.

Mental Illness

Mental, behavioral, and emotional disorders can reduce a person's enjoyment of life and their ability to perform daily tasks. The main types of these are:

• Anxiety
• Bipolar Disorder
• Depression
• Post-Traumatic Stress Disorder (PTSD)
Schizophrenia​

Imagine that your brain is like a computer, and your mind is like the software that runs on it. In other words, your mind is the 'operating system' of your brain. Psychiatrists and psychologists are like computer programmers who figure out why this software doesn't work properly and causes problems.

Often, treatment involves both medication and talk therapy. Some people are hesitant to see a mental health professional. But that's not necessarily the case. Mental illness affects one in five adults, so it's important to be open about it and seek help.

Neurodegenerative Brain Diseases

These diseases are often caused by abnormal protein deposits in the brain. Simply put, brain cells are gradually destroyed. These gradually increase in number. This category includes:

• Alzheimer's disease
• Parkinson's disease
• Many diseases like ALS (Amyotrophic Lateral Sclerosis) are inherited.

These are often gradual and get worse over time. They can affect thinking, memory, movement, or a combination of these. They are more common in older people. Some of them are hereditary.

Neurodevelopmental Disorders

These disorders affect the growth and development of the brain, especially during childhood. They are usually treated by pediatric neurologists. Sometimes a medical geneticist can determine if it is hereditary. If so, they can provide advice to the family. There are many types of neurodevelopmental disorders, including:

• Attention Deficit Hyperactivity Disorder (ADHD)
• Autism Spectrum Disorder
• Dyslexia ( reading difficulties)

Stroke

A stroke, or 'paralysis' as some call it, occurs when a blood vessel that supplies the brain with nutrients becomes blocked, or rarely bursts. However, the effects are immediate. A stroke damages part of the brain. This can cause problems with speech, understanding, vision, strength, sensation, or coordination. If the brain is severely damaged by one or more strokes, it can also lead to dementia, a disease that causes memory loss . Sometimes, a stroke can cause seizures.

Traumatic Brain Injuries

This category includes things from minor injuries like concussions to serious brain injuries like gunshot wounds. Brain injuries can occur from falls, car accidents, sports accidents, or domestic violence (including child abuse). Repeated blows to the head can cause scarring in the brain, leading to a condition called chronic traumatic encephalopathy (CTE) . Neurosurgeons treat injuries and bleeding inside the brain. Psychologists, psychiatrists, and speech therapists help with behavioral and thinking problems that arise after brain injuries. Neurologists also treat people who have been injured.

Brain Tumors

Cancers that develop in other parts of the body, such as the lungs, breast, or colon, can spread to the brain and form tumors. Or, these tumors can form in the brain tissue itself or in the coverings of the brain.

• Unlike tumors that spread from other parts of the body, tumors that form in the brain itself or in the meninges are considered benign, meaning harmless , if they grow spontaneously and do not damage the surrounding brain tissue.
• However, if they grow rapidly and invade surrounding brain tissue, they are considered malignant, meaning they are severe and cancerous tumors .
• Astrocytoma is a common tumor that develops within the brain. Meningioma is a common tumor that develops in the coverings of the brain.

How common is this brain disease?

Brain diseases really do affect a lot of people. But the incidence of each disease varies from person to person. For example, if you look at the statistics in the United States:

• Alzheimer's disease affects more than 6 million people.
• Autism spectrum disorder affects about 1 in 44 children.
• Brain tumors and other cancers of the nervous system are slightly less common, accounting for about 1.3% of all cancers.
• Epilepsy affects 1.2% of the population. That's about 3 million adults and 470,000 children.
• Meningitis is now much less common thanks to the vaccine. Only 371 cases were reported in 2019.
• Mental illness is very common, affecting one in five adults.
• Nearly one million people live with multiple sclerosis .
• Strokes occur in close to 800,000 people every year.
• More than 220,000 people were hospitalized in 2018 due to traumatic brain injuries .

What are the causes of brain diseases?

There are several common causes and risk factors that contribute to the development of brain diseases:

• Environmental toxins and radiation: Long-term exposure to toxic chemicals and radiation can increase the risk of developing certain diseases, such as brain tumors.
• Genetics: Certain genes and genetic mutations can cause or increase the risk of developing many brain diseases. Researchers have identified genes linked to brain tumors, epilepsy, neurodegenerative diseases, neurodevelopmental disorders, and mental illnesses. The genes that cause these diseases can be inherited or can occur randomly.
• Immune system function: Autoimmune brain diseases occur when our immune system attacks our own body cells.
• Infections: Organisms like bacteria and viruses can cause brain diseases like meningitis.
• Injuries: Accidents and injuries are the most common cause of traumatic brain injuries. A brain injury can also increase the risk of developing other brain diseases, such as epilepsy and Alzheimer's disease.
• Unhealthy lifestyle choices: Things like poor eating habits, lack of exercise, smoking, and alcohol use have been found to be linked to stroke and Alzheimer's disease.

Doctors are still not sure why some types of brain disorders develop. For example, about 60% of epilepsy cases have no known cause (idiopathic). Researchers are continuing to study these brain disorders to find causes and treatments.

What are the symptoms of brain disease?

As you know, the brain controls every function in our body. So if the brain is injured or diseased, any function can be affected, depending on the type, location, and severity of the disease. You may experience common symptoms such as:

• Fever
• Headache (especially a new, severe, or unusual headache)
• Nausea and vomiting
• Seizures
• Unconsciousness

Additionally, brain diseases can manifest as changes in the following:

• Balance
• Behavior
• Breathing
• Coordination
• Focus
• Memory
• Mood
• Movement
• Personality
• Physical sensations (e.g. numbness, loss of sensation)
• Speech (e.g. stuttering, difficulty finding words)
• Strength (especially on one side of the body)
• Swallowing
• Vision (e.g., sudden blurred vision, double vision)

The most important thing is that if you have one or more of these symptoms that are unusual, sudden, or gradually increasing, see a doctor immediately. Don't take it lightly.

How to diagnose brain diseases?

The most important steps in diagnosing a condition are a history and a physical exam. During the physical exam, the focus is on the neurological exam. This includes tests that measure movement, sensation, reflexes, and thinking ability. The findings of this exam will determine what other tests are needed.

Other tests may include:

• Biopsy: The doctor takes a small sample of tissue and tests it in a lab. A biopsy helps determine whether a brain tumor is cancerous or not.
• Diagnostic testing: This includes tests such as an electroencephalogram (EEG), which measures the electrical activity of the brain. There are also tests called evoked potentials testing, which look at how nerve signals are transmitted to the brain.
• Imaging tests: CT scans , MRI scans , and PET scans can produce detailed images of the brain. These can help identify brain function and areas that are diseased or damaged.
• Laboratory tests: Blood, urine, stool, or spinal fluid tests can help your doctor understand the cause of your symptoms. Genetic testing can also be done to identify genetic mutations that cause some brain diseases.
• Mental function tests: These are tests that are done on paper or on a computer. These tests allow your doctor to assess your memory, thinking, and problem-solving abilities.

How are brain diseases treated?

Aside from preventing the disease before it develops, treatment methods vary depending on the type of disease.

• Some diseases can be cured (for example, giving antibiotics for meningitis, or removing a tumor).
• Some others can be treated, but not completely cured (for example, giving medication to control the symptoms of Parkinson's disease, or giving medication to prevent seizures).
• Some others we need to adapt to (for example, using a cane for some balance problems).

Your doctor may use treatments such as:

• Counseling and Cognitive Behavior Therapy: Manage mental health issues and provide emotional support.
• Diet, exercise and stress management: Reduce symptoms of some conditions, such as Alzheimer's and multiple sclerosis, and prevent stroke recurrence.
• Medications: Treat the disease and manage symptoms.
• Minimally invasive endovascular surgery: Repair a ruptured blood vessel.
• Physical, occupational or speech therapy: Regain lost abilities.
• Rest: Help the brain heal.
• Surgery: To stop internal bleeding, remove a brain tumor, or prevent epileptic seizures.

Can brain disease be prevented?

There's a saying that goes, 'An ounce of prevention is worth a pound of cure.' That's really true.

Preventable brain diseases can be avoided by eating a healthy diet and living an active lifestyle, controlling diseases such as high blood pressure, diabetes , and high cholesterol , and getting vaccinations against infections that affect the brain and nervous system.

These general guidelines can help reduce your risk of preventable brain diseases:

• Following a healthy lifestyle: This includes a heart - healthy diet,These include exercise, avoiding smoking, limiting alcohol consumption, and reducing stress.
• Avoiding excessive exposure to X-rays and other radiation sources.
• Make sure you and your loved ones are vaccinated against Bacterial Meningitis .
• Know the warning signs of a stroke and seek emergency medical attention immediately.
• Managing chronic health conditions like high blood pressure, high cholesterol, diabetes, and obesity .
• Reduce the risk of head injuries by avoiding falls, wearing seat belts when driving, and wearing helmets when riding bicycles or playing contact sports.
• Staying mentally and socially active.

What is the future if you develop a brain disease?

Some brain diseases resolve without permanent damage. Others may resolve, but they can leave some impairment in your mental or physical abilities. Others are lifelong, progressive conditions. Your doctor will work with you to help you manage your symptoms and maintain or regain as much function as possible. Don't worry, with the right treatment and support, many things can be managed.

When should I see a doctor?

It's important to seek early treatment for brain injuries and illnesses. Get checked out by a doctor even if you have a minor head injury. Also, let your doctor know if you notice any unusual changes in any of the following:

• Behavior, mood, or personality
• Memory and attention span
• Physical function, including movement, balance, and coordination
• Speech
• Vision

If you have any of the warning signs of a stroke, call 911 immediately! These are changes that usually occur quickly, without pain:

• Speech changes (stuttering or confusion) or difficulty understanding others.
• Difficulty seeing in one or both eyes.
• Sudden severe headache.
• Loss of balance, coordination, or ability to walk.
• Weakness or numbness in the face, arm, or leg, especially on one side of the body.

What is the message we want to take home from this article?

There are many types of brain diseases. Some are very common, while others only affect a few people a year. Your doctor will examine you carefully to find out exactly what is causing your symptoms and to give you the best treatment plan. If you or someone in your family has had a brain injury or disease, follow your doctor's advice for treatment and long-term management. Therapy, medication, lifestyle changes, and the right support can help you live as full a life as possible.Don't forget, brain health is a very important part of our overall health!
