Diseases are medical conditions that affect the body and disrupt its normal functions. Although healthcare professionals and researchers have made significant progress in finding cures for many diseases, there are still several illnesses without a permanent cure.

While treatment may help manage symptoms or prolong life, the diseases themselves remain incurable.

In this article, Tribune Online takes a look at six incurable diseases you should know.

HIV/AIDS

Probably the most well-known disease on the list, Human Immunodeficiency Virus (HIV) is a virus that attacks and weakens the immune system, which can develop into Acquired Immunodeficiency Syndrome (AIDS). At this stage, the immune system becomes too weak to fight infections. Although antiretroviral therapy (ART) helps patients live long and healthy lives, there is still no permanent cure for HIV.

Causes

HIV is primarily contracted through specific bodily fluids: blood, semen, vaginal fluids, anal mucus, and breast milk. The most common ways HIV is spread are through unprotected vaginal or anal sex and sharing needles or syringes. Mother-to-child transmission can occur during pregnancy, childbirth, or breastfeeding.

Cancer

Cancer is a disease caused by the uncontrolled growth of abnormal cells, affecting organs such as the lungs, breasts, and prostate. Treatments like surgery, chemotherapy, and radiation can manage or remove some cancers, but there is no universal cure.

According to Healthline, there is a difference between cure and remission when it comes to cancer. A cure means all traces of cancer are eliminated and will not return, while remission refers to a state where few to no cancer cells remain. Remission may be complete, with no detectable signs of cancer, often within the first five years after treatment, or partial, where the cancer has shrunk but is still present. Even in complete remission, hidden cancer cells can remain and cause the disease to return.

Causes

Cancer, unlike HIV, is not a contagious disease. Instead, it arises from genetic mutations within cells, which can be inherited, develop over time, or be caused by environmental factors like radiation and chemicals. These mutations cause cells to grow and divide uncontrollably.

Diabetes

Another incurable disease is diabetes. It is a chronic condition where the body cannot properly control blood sugar levels.

While there are many types of diabetes, the major ones are Type 1 and Type 2. In Type 1 diabetes, the body produces little or no insulin, while in Type 2 diabetes, the body cannot use insulin effectively. Although medications, insulin injections, and lifestyle changes help manage the disease, there is no cure. Over time, diabetes can lead to complications such as kidney failure and heart disease.

Causes

Diabetes is also not contagious. Type 1 diabetes is mainly due to genetics and environmental factors that trigger the immune system to attack insulin-producing cells in the pancreas while Type 2 diabetes on the other hand is caused by a combination of factors such as genetics, lifestyle, and insulin resistance

Alzheimer’s Disease

Alzheimer’s disease is a brain disorder that slowly destroys memory and thinking abilities. It is the leading cause of dementia among older adults. The disease worsens over time and makes it difficult for patients to perform daily activities. Current treatments can only slow down symptoms or improve quality of life, but they cannot stop the disease or reverse the damage.

Causes

Alzheimer’s develops in the brain when abnormal protein deposits build up, damaging nerve cells and affecting memory. Age, genetics, and family history are the strongest risk factors, while lifestyle factors such as poor cardiovascular health can also contribute to the development of this incurable disease.

Amyotrophic Lateral Sclerosis (ALS)

Not only is this disease incurable, but it also does not have a known cause, according to Professor of Neurology Mayowa Owolabi. Amyotrophic Lateral Sclerosis, commonly known as ALS or Lou Gehrig’s disease, is a progressive neurological disorder that affects the nerve cells controlling voluntary muscles. Over time, the nerves that send signals from the brain to the muscles weaken and die, causing patients to lose the ability to move, speak, eat, and eventually breathe.

Causes

ALS is not a disease that spreads from person to person. The exact cause is unknown, but research suggests it results from a mix of genetic and environmental factors. In some cases, it runs in families, while in others, it occurs randomly.

Parkinson’s Disease

This is another disease scientists have yet to find a cure for. It is a progressive disorder of the nervous system that mainly affects movement. Parkinson’s disease develops gradually and is marked by tremors, stiffness, and difficulty with balance and coordination.

The condition occurs when nerve cells in the brain that produce dopamine become damaged or die. While medications and therapies can help control the symptoms, there is no cure for Parkinson’s disease, and symptoms worsen over time.

Causes

Like some other incurable diseases, Parkinson’s does not spread like an infection. It develops when nerve cells in the brain that produce dopamine become damaged or die. While the exact cause is not fully understood, Mayo Clinic notes that factors such as genes and environmental toxins may play a role in the development of the disease.
