Causes, risks, and symptoms of Huntington’s disease

Causes, risks, and symptoms of Huntington’s disease

Huntington’s disease is a rare disorder that affects the brain cells, leading to several physical, cognitive, and emotional symptoms. It is a hereditary neurodegenerative disease that attacks the central nervous system. It’s important to note that there is currently no cure for it. However, understanding the early causes of the disease, assessing risks, and identifying signs and symptoms of Huntington’s disease in detail will provide a comprehensive understanding of this condition.

Causes
The following are the genetic causes linked to the development and progression of Huntington’s disease (HD).

Genetic mutation
HD is caused by a mutation in the HTT gene, which is on chromosome 4 in the DNA segment. This mutation causes the production of mutant huntingtin (mHTT), which is an abnormal protein.

Excess protein accumulation
The mutant huntingtin protein has a tendency to aggregate and form clusters within neurons, interfering with their function and causing damage to brain function. This mutant protein is toxic to nerve cells, particularly in certain regions of the brain, leading to their dysfunction and eventual death.

Impaired cellular transport
Nerve and cell damage disrupts the transport of vital molecules within neurons. This affects one’s ability to communicate and function properly to facilitate tasks and familiar actions.

Excitotoxicity
The mutant gene can make neurons more susceptible to excessive stimulation by neurotransmitters, leading to excitotoxicity and neuronal fatality.

Inflammation
One of the persistent symptoms of brain disorders is inflammation of healthy cells that also disrupts communication, contributing to neurodegeneration.

Neurodegeneration
The progressive degeneration of specific brain regions, including the striatum and cortex, are among the leading causes of HD. This neurodegeneration is responsible for the characteristic motor, cognitive, and psychiatric symptoms of HD.

Risk factors of Huntington’s disease
There are many risk factors that also dictate the progression of this disease and impact future outlook.

Genetic mutation
Having a family history of the condition is the most significant risk factor for developing it. If either parent carries a mutated HTT gene, the upcoming generation has a 50% chance of inheriting the mutation and developing Huntington’s. Genetic testing can determine whether the parent carries the gene or not. However, the severity and age of onset can vary among affected individuals. Nevertheless, this information can inform family planning decisions.

Age
Huntington’s disease risk increases with advancing age. It is predominantly present in adulthood, usually between the ages of 30 and 50. Although it can affect individuals at any age, the risk increases as a person ages, loses immunity, or even develops comorbidities and other health complications.

Spontaneous mutations
While rare, spontaneous mutations can occur in individuals with no family history of Huntington’s disease. These cases are not inherited from parents but are the result of a new mutation in the gene found among the affected people. However, the chance of this inheritance is quite rare.

Symptoms of Huntington’s disease
Cell damage disrupts vital communications sent from the brain to all organs and extremities of the body. As a result, a person will experience various symptoms, ranging from mild muscle pain to severe cognitive impairment.

Chorea
Involuntary, jerky, and uncontrollable movements are known as chorea. This is one of the more easily noticeable signs that affect a person early on with the disease progression. These movements often start subtly with mild fidgeting or restlessness and progress to more pronounced and disruptive motions that cannot be controlled to any extent. Chorea can affect various parts of the body, including the face, arms, and legs, sometimes developing simultaneously, affecting multiple muscle groups, depending on the intensity of the condition.

Muscle stiffness and rigidity
A person with HD can also experience muscle stiffness or rigidity that develops with the disease progression. Without flexible muscle movements, one will face great difficulty in controlling simple actions. The rigidity only further causes muscle cramps and pain to develop. The combination of chorea and muscle rigidity can contribute to a significant loss of motor function over time if left unchecked.

Problems with simple tasks
HD affects the brain’s ability to coordinate movements and maintain proper balance while performing certain tasks. As a result, one might experience frequent falls and struggle to maintain posture. As the disease progresses, individuals often experience a decline in their ability to perform everyday motor skills such as writing, typing, or buttoning a shirt. This can affect activities like dressing, grooming, and cooking, thus increasing their dependence on friends and family.

Speech and swallowing difficulties
The brain also controls automatic muscle movements and actions that govern actions like eating and swallowing. Cell damage triggered by Huntington’s disease results in one developing speech and swallowing problems. One’s speech might become slurred and difficult to comprehend, and swallowing difficulties further increase the risk of choking. Speech therapy may be needed to manage these issues in the long run, as Huntington’s is a progressive disorder.

Cognitive decline
Huntington’s disease will impact cognitive functions. Some of the early signs include difficulties with focus, retention, and problem-solving abilities. These are basic functions that are required to accomplish day-to-day tasks. As the disease progresses, one might experience more severe cognitive decline that also affects their ability to think, reason, and arrive at a decision.

Emotional changes
Huntington’s disease triggers a wide range of emotional and psychiatric symptoms. It is common for a person to experience unexpected mood swings, irritability, depression, and anxiety. These emotional changes impact relationships and greatly affect one’s quality of life, making it challenging for both the affected individual and their loved ones.

Changes in personality
Behavioral changes can manifest in various ways, triggering impulsivity, apathy, aggression, and social withdrawal. Caregivers and healthcare professionals must be prepared to address these behavioral challenges and provide appropriate support.

The outlook for individuals with Huntington’s disease (HD) will vary widely depending on several factors, including the age of onset, the severity of symptoms, and the availability of support and healthcare. There is no cure, so doctors will advise on the best course of treatment to better manage the condition.

Foods to Eat and Avoid for Optimal Kidney Health

Kidneys help filter waste from the blood and dispose of it off the body via urine. They also help balance the electrolyte and fluid levels in the body. But, conditions like high blood pressure and diabetes may intervene with their ability to work as required. Furthermore, damage to the kidney might also result in chronic kidney disease. Hence making changes in your meal plan is a vital aspect of treatment. You can prevent damage to these organs by following a kidney-healthy meal plan. Below, we will address some foods to eat and avoid for better kidney health. Foods to eat Cauliflower Cauliflower is a nutritious vegetable. It's an excellent source of folate, Vitamins B, K, and C. It's rich in anti-inflammatory compounds like indoles, a fiber source. In addition, you can use mashed cauliflower as a replacement for potatoes. For example, a cup of cooked cauliflower has 40 mg of phosphorous, 176 mg of potassium, and 19 mg of sodium. Sweet potatoes They are relatively similar to white potatoes but have more fiber content, resulting in them breaking down more gradually. Hence, you will experience a less spike in insulin levels. Sweet potatoes are also rich in vitamins and minerals like potassium that help balance the sodium levels in the body and lower their impact on the kidneys. But, since sweet potatoes have a high potassium content, people on dialysis or those with CKD should curtail the intake of this vegetable. Red bell peppers They are rich in flavor and low in potassium, but that is not the sole reason they are considered a hit among people with kidney disease. Red bell peppers have Vitamin C and A sources and are also high in fiber, folic acid, and B6 vitamin content. In addition, red bell peppers are also suitable because they have lycopene, an antioxidant that shields against some cancers. You can eat them raw with a dip, mix them into your salad, or enjoy them as an appetizer. Some people also like roasting bell peppers and using them as a topping for lettuce salads or sandwiches. Olive oil It contains healthy fat and has anti-inflammatory properties. Since it is monosaturated fat, it stays stable even at higher temperatures as you cook. Thus, switching to extra virgin olive oil can give you more antioxidants while you still enjoy your favorite dish. Green vegetables Leafy veggies like spinach, kale, romaine, arugula, and cabbage are hydrating, low in calories, and have high antioxidant and vitamin content. If you wish to be cautious about your mineral levels, you must opt for cabbage and arugula, which are nutrient-rich and lower in sodium, potassium, phosphorous, and calcium. In addition, kale and spinach have a high potassium content, which is ok for people seeking to improve their kidney health, but best for those already dealing with chronic kidney disease. Blueberries They are called superfoods because they are rich in antioxidants and are a low-calorie Vitamin-C and fiber source. You can stock them in abundance from your local grocery store or farmer’s market. You can also shop for frozen berries in the off-season and enjoy healthy smoothies. People with kidney diseases can also eat other berries like raspberries, cranberries, and strawberries. Apples Apples are low in potassium and rich in fiber when you eat them with peel. They also have a natural anti-inflammatory effect and are ideal for your kidneys. Foods to avoid Soda Soda has zero nutritional benefits and instead has high sugar content. It only adds to the extra calories. Some studies link high soda consumption to conditions like kidney disease, osteoporosis, dental problems, and metabolic syndrome. If you opt for their lower calorie alternative like coke zero, even that will do you no good, as it has no nutritional value and contains artificial sweeteners and additives. Hence, you must omit soda and opt for healthy beverages like water. If you do not enjoy plain water, add a slice or two of fresh fruit for added flavor. Avocados Avocadoes are known for their many nutritious qualities. They are rich in antioxidants, fiber, and heart-healthy fats. Even though consuming avocado is often considered healthy, people with kidney disease must avoid it as avocados have a high potassium content. An average-sized avocado has about 690 mg of potassium. If you love the taste and do not want to eliminate it, you can reduce the portion size to only 1/4th of the avocado. In addition, it will lower potassium intake.  Salty foods Sodium or salt is one of the most prevalent inclusions in foods you consume daily. However, their density is higher in processed foods. Salt results in water retention and may cause blood pressure, lung, and heart disease. Healthy kidneys work towards maintaining the correct fluid balance in the body. So, if your kidneys do not function as desired, the fluid balance may be disturbed. Hence, you must curtail sodium-rich foods like processed foods, packaged items, and soy sauce. When cooking meals at home, opt for low-sodium alternatives. You can replace salt with spices and herbs and keep the salt shaker off the table. Dairy Dairy products like yogurt, cheese, ice cream, and milk are rich in protein, calcium, and other vital nutrients. They also contain potassium and phosphorous. People with stage three kidney disease might want to curtail their potassium, phosphorous, and protein intake, which is high in dairy. So, you can instead reach out for dairy alternatives like rice, soy, or almond milk as they have lower potassium, phosphorous, and protein content than cow’s milk. Bananas Though naturally low in sodium, bananas' potassium content is significantly high. So, to ensure your kidney disease does not aggravate, monitor your potassium intake, and it might be challenging if the banana is your staple. Conclusion Whatever you eat or drink will affect your health regardless of any health issue. Therefore, maintaining a healthy weight and following a balanced meal plan are prerequisites to staying fit and controlling blood sugar levels. A kidney-healthy meal plan is less about eliminating certain foods but following portion control and finding a balance of proteins, carbohydrates, and fats.

11 signs of lung cancer that must not be ignored

Lung cancer often conceals its presence until it reaches advanced stages. Timely detection is critical, making recognition of its early signs paramount. This article explores the subtle yet significant indicators that may precede a lung cancer diagnosis. From persistent coughs and unexplained chest pain to voice changes, understanding these warning signals could be a lifesaver, enabling individuals to seek prompt healthcare attention and potentially altering the course of this formidable disease. Persistent cough A persistent cough is a red flag in the realm of lung cancer. While it might have various causes, a chronic cough that lingers for weeks or worsens over time should not be underestimated. In many cases, lung cancer may be silently advancing, obstructing air passages, or irritating the respiratory system. This cough may be accompanied by mucus or blood, demanding immediate evaluation. Early detection is pivotal, as timely intervention improves lung cancer's prognosis significantly. Anyone experiencing an enduring cough, particularly if coupled with other concerning symptoms, should promptly consult a doctor to rule out the possibility of lung cancer. Shortness of breath Shortness of breath may serve as a distressing indicator of underlying lung cancer. This symptom often emerges when a tumor obstructs air passages, compresses the lungs, or invades the pleural space. Individuals may notice a gradual onset of breathlessness, which may worsen during physical exertion. Although numerous factors could cause shortness of breath, unexplained, persistent dyspnea should raise concerns. Early recognition and evaluation by a healthcare professional are essential, as addressing lung cancer at its outset yields the most favorable outcomes. Chest pain Chest pain, while not always linked to lung cancer, might be an alarming symptom that warrants attention. Lung cancer-related chest pain typically occurs when a tumor presses against nearby nerves, the chest wall or inflames the lining of the lungs. The pain may be sharp, aching, or discomforting and could be exacerbated with deep breaths, coughing, or laughter. It is important to consult a healthcare professional for a thorough evaluation to rule out lung cancer or address it at an early, more treatable stage. Hoarseness and voice changes Hoarseness and voice changes might be early signs of lung cancer, often resulting from tumor-related compression or damage to the nerves controlling the vocal cords. These alterations in vocal quality may manifest as a persistent, raspy, or deeper voice. Although hoarseness may result from numerous factors, its persistence, especially when coupled with other concerning symptoms, should not be ignored, particularly in individuals with lung cancer risk factors. Early detection is key, as it may lead to timely intervention and improved prognosis. Experts should conduct a comprehensive evaluation to rule out or address lung cancer. Yellowing of the skin If an individual is suffering from lung cancer, there is a possibility that they may experience yellowing of the skin if the disease has spread to their liver. The whites of their eyes may also turn yellow due to the cancer. The cause of this is the accumulation of bilirubin in the body, which is a substance created during the normal breakdown of red blood cells. However, if the mutation has spread to the liver, pancreas, or bile ducts, it can result in higher than normal bilirubin levels. This can lead to the symptoms mentioned earlier. Fatigue Fatigue is a common symptom in cancer patients, including those with lung cancer. It could result from the body's immune response to cancer cells, the energy expended by the tumor's growth, or anemia caused by cancer treatment. If fatigue is persistent and unrelated to other factors like excessive physical activity or sleep deprivation, it should be investigated further. Wheezing Wheezing is a high-pitched whistling sound that can occur while breathing and could be a symptom of lung cancer. This symptom often arises when a tumor obstructs or narrows the airways, leading to turbulent airflow. While wheezing might be caused by various respiratory conditions, its persistence or unexplained onset should not be ignored. Timely evaluation by a healthcare professional is crucial to rule out or address lung cancer. One should also note that detecting and addressing wheezing in its early stages may significantly improve the prognosis and increase the chances of successful treatment. Frequent respiratory infections Frequent episodes of bronchitis or pneumonia could be a potential indicator of lung cancer. Lung cancer might obstruct air passages or interfere with the immune system's ability to fend off infections, making individuals more susceptible to respiratory infections like bronchitis and pneumonia. One should visit an expert to determine the cause of these symptoms immediately. Swelling of the neck and face In some cases, lung cancer causes the superior vena cava (SVC) syndrome, which occurs when the tumor obstructs the SVC, a large vein that carries blood from the upper body to the heart. This obstruction could lead to swelling in the neck and face, as well as other symptoms like headache, dizziness, and difficulty swallowing. Clubbed fingers This is a condition where the fingertips and nails become enlarged and rounded, which could be a rare but significant indicator of underlying lung cancer. The unusual and visible change in finger appearance often results from chronic low oxygen levels in the blood, which might occur when lung cancer impedes normal respiratory function. While the sign could also be linked to other health conditions, its presence, particularly in individuals with risk factors for lung cancer, should not be overlooked. Pain in the bones Bone pain could be a concerning symptom associated with lung cancer, especially when the cancer has metastasized or spread to the bones. Lung cancer cells may invade and weaken bones, leading to localized or widespread pain. This pain is often described as deep, aching, or persistent and might occur in various areas, such as the spine, ribs, and hips. Someone who develops this sign should speak to their healthcare specialist for an opinion.

Atrial Fibrillation – Causes, Signs, and Remedies

Atrial Fibrillation – Causes, Signs, and Remedies

Atrial fibrillation, or AFib, is characterized by an irregular heart rhythm or arrhythmia in the atria or the heart’s upper two chambers. It causes a disturbance in the typical cycle of the electrical impulses in the heart. The condition results in a rapid and chaotic heart rhythm and poor blood movement from the upper chambers to the ventricles or the lower chambers. Below, we address the causes, symptoms, diagnosis, treatment, and management of AFib. Causes AFib, or a change in the electrical signals in the heart, can affect anyone, regardless of age. But it is more prevalent in older people. A few risk factors that amplify the condition’s susceptibility are: Heart diseases People with an underlying heart condition, like a heart attack, coronary artery disease, and heart failure, have a greater risk of AFib. Hypertension If left unchecked, high blood pressure can strain the heart and aggravate the risk of this disorder. Familial link People with a family history of AFib have a greater chance of suffering from the condition. Sleep apnea This sleep disorder can also increase a person’s susceptibility to AFib, especially if it is severe. Besides the above, other chronic conditions like diabetes, asthma, and thyroid also put a person at risk of this heart problem.

Macular Degeneration – Causes, Symptoms, and More

Macular degeneration is a progressive disease that destroys the macula, the part of the eye that allows you to see fine details. It can make activities like reading, writing, and driving difficult or impossible. The disease typically occurs in older adults and can lead to blindness. While macular degeneration can be managed in its early stages, it has no cure. This article discusses the causes, risk factors, symptoms, and treatments of macular degeneration. What is macular degeneration? Macular degeneration is a disease of the retina, the light-sensitive layer at the back of your eye. There are two types of macular degeneration: dry and wet. The former develops when the macula dries out and loses its function. Wet macular degeneration is a result of new blood vessels under the retina leaking fluid or blood, causing vision loss. Symptoms of macular degeneration The symptoms of macular degeneration can develop differently in individuals, but here are the typical signs one must note. One of the main symptoms is a gradual loss of central vision, which can progress over time and may not be noticeable at first. Additional symptoms are difficulty reading small print or close-up objects, trouble seeing in dim light or when looking up from a low angle, problems with depth perception and peripheral vision, and poor night vision.

Nasal Polyps – Symptoms, Triggers, and Management

Nasal Polyps – Symptoms, Triggers, and Management

Nasal Polyps are a significantly underrated problem. Most people only experience minor symptoms, so the polyps are often left untreated until they cause more problems. This article will look at the triggers, symptoms, and management of nasal polyps in more detail. We will start by looking at nasal polyps and what causes them. Finally, we will look at the best ways to treat nasal polyps to ensure that one gets rid of them quickly and safely. What are nasal polyps? Nasal polyps are benign growths on the nasal septum, the cartilage that separates one’s nose from the throat. They’re usually harmless but can cause problems if they block the nasal airway or make breathing difficult. Symptoms of nasal polyps Following are some symptoms of nasal polyps: Headaches Nasal polyps may cause headaches due to their enlarged blood vessels in the skull. The pressure from these enlarged vessels may cause pain behind one’s eyes or along the temples. Snoring Snoring is often caused by an obstruction of airflow through the nose during sleep. This obstruction causes the throat to vibrate, producing a noise known as snoring. Nasal congestion When mucus accumulates in the nose due to blocked airflow, it can cause nasal congestion and an unpleasant smell called rhinorrhea (a discharge from the nose).

10 Effective Tips for Managing Ulcerative Colitis

10 Effective Tips for Managing Ulcerative Colitis

Chronic inflammation of the large intestine, or ulcerative colitis , is a devastating and exhausting disease that can wreak havoc on every aspect of one’s life. From physical health to mental well-being, ulcerative colitis can take a toll on overall health if left untreated. Here are simple ways to manage ulcerative colitis. By following them under a doctor’s supervision, you can take back control of life and manage the condition better. What is ulcerative colitis? Ulcerative colitis (UC) is a form of inflammatory bowel disease (IBD) that causes long-lasting inflammation and ulcers in the digestive tract. UC acts on the innermost walls of the large intestine (colon) and rectum. It is a chronic condition that can last for months or even years. Types of ulcerative colitis Ulcerative proctitis is the most common type and accounts for about two-thirds of all UC cases. People with this type have frequent episodes of diarrhea, abdominal pain, and fever. Ulcers may form in the rectum or anus. Proctosigmoiditis is less common than ulcerative proctitis but affects more people overall because it causes more severe symptoms, such as bloody diarrhea that may lead to dehydration and malnutrition. Extensive colitis/pancolitis occurs when inflammation spreads beyond the rectum or anus to other parts of the gastrointestinal tract (large intestine and small intestine).
