  Alzheimer is a type of dementia that affects memory, thinking and behaviour. Symptoms can grow severe enough to interfere with daily tasks. It's the most common cause of dementia, a general term for memory loss and other cognitive abilities serious enough to interfere with daily life.  This disease is not a normal part of aging. It is a progressive disease beginning with mild memory loss and possibly leading to the ability to carry on a conversation and respond to the environment. Researchers believe that genetics may play an important role in developing Alzheimer's disease. However, a healthy lifestyle may help you reduce your risk of developing it. Adequate physical activity, a nutritious diet, a limited alcohol consumption and not smoking may help people. Changes in the brain start years before the first symptom. Alzheimer worsens over time. Memory problems are usually the first warning signs. But the people with it can also experience: trouble handling money, difficulty ...

More than 12% of the children between ages of 6 and 19 already have hearing damage from loud noises. Your child's hearing health is crucial during their overall well-being and development. Hearing loss is increasingly common among children, teens, and young adults. HOW OUR EARS WORK 1. Outer ear: sound waves enter the outer ear and travel through the ear canal. 2. Middle ear: the sound waves hit the eardrum, causing it to vibrate. These vibrations are transferred to the malleus, incus and stapes. 3. Inner ear: the vibrations hit the cochlea and it creates electrical signals. 4. Brain processing: the auditory nerve carries them to the brain, interpreting them as a sound. MEASURING SOUND Sound is measured in decibels (dB). Sounds at or below 70 dB are generally considered safe. Any sound over 85 dB poses a risk of damaging your hearing over time. A normal conversation is usually between 60 and 70 dB. Music by headphones at maximum can reach to 94 to 110 dB. CAUSES OF CHILDHOOD HEARIN...

  Infectious diseases are diseases caused by microorganism —such as bacteria, fungi, viruses or parasites. The microorganism enters a person's body and causes harm. Many organisms live in our body, and most of them are harmless or even helpful. The microorganism uses the human body to sustain itself, reproduce and colonize. These infectious microscopic organisms multiply quickly. They can spread by different ways, including: skin contact, transfer of bodily fluids, contact with feces, ingesting contaminated food/water, etcetera.  Signs and symptoms vary depending on the organism that caused the infection, but often include fever and fatigue. Mild infections may respond to rest and home remedies, while some life-threatening infections may need hospitalization. Many infectious diseases can be prevented by vaccines. Frequent and thorough hand-washing also helps protect you from most infectious diseases. Bacteria, viruses, parasites and fungi vary in several ways: size, shape, fun...

  Tourette syndrome is a neurodevelopmental disorder that affects children, adolescents and adults. It affects the brain and nerves, causing people to do repeatedly movements and sounds (motor and vocal tics) that they cannot control. Tics can range from mild to moderate and severe, and are disabling in some cases. It's important to know that people with Tourette don't always blurt out obscenities or curse words, it is a misbelief sometimes seen on TV. Only in 10-15% of the cases the words may be inappropriate. Also, just having a tic doesn't mean you have Tourette: to have Tourette means that a person has at least two different motor tics and one vocal tic, and has had tics for over a year. Some other rules for the diagnosis are: tics started to appear before the age of 18, and they're not caused by the use of substance or other medical condition. Tics typically appear at the age of 5 to 7 years, they tend to increase in severity and frequency between the ages of 8 and...

There are two types of problems with your thyroid: it can produce too much hormones (hyperthyroidism) or not enough (hypothyroidism). Both of the situations can cause problems. The thyroid gland is a small, butterfly - shaped gland in the base of your neck. It's part of the network of glands called endocrine system. This system is responsible of a lot of our body's activities. And in this case the thyroid gland manufactures hormones that regulates your body's metabolism. When your thyroid is overproducing or underproducing it can cause symtoms like irritability, weigh loss, weigh gain, fatigue and m ore.  Four common issues associated with the thyroid i nclude Hashimoto’s thyroiditis, Graves’ disease, goiter (enlarged thyroid), and thyroid nodules. HYPERTHYROIDISM The gland is overacting and there is too much thyroid hormone. Many of your body's functions can speed up. It is more common in women. The treatment can be: antithyroid medication, radioiodine therapy, beta-bl...

  Diabetes is a chronic disease that occurs either when the pancreas does not produce enough insulin or when the body can't effectively use the insulin it produces. Insulin is an hormone that regulates blood glucose. Uncontrolled diabetes can cause raised blood glucose (hyperglycaemia) and over time it leads to serious damage to the body's systems. Symptoms of diabetes can occur suddenly. In type 2 diabetes they can be mild and may take many years to be noticed. The symptoms may include: feeling very thirsty, needing to urinate more than usual, blurred vision, feeling tired, losing weight unintentionally. Over time, diabetes can damage blood vessels in the heart, eyes, kidneys and nerves. TYPE 1 DIABETES It's characterized by deficient insulin production and requires daily introduction of insulin. TYPE 2 DIABETES It affects to how your body uses glucose for energy. It stops the body for using glucose properly, which can lead to high levels of blood sugar if it's not tre...

  We need constant oxygen supply to our surviv al, a nd a heart attack generally occurs when the blood flow gets hampered due to certain reasons. SYMPTOMS The primary  symptoms  are: breathing problems, cold sweat, indigestion, fatigue, sudden dizziness,  pressure  aching sensation in the chest. These basic symptoms are quite common but they can vary between people. Some diabetic patients have silent symptoms. DIAGNOSIS Depending on all the risk factors and the symptoms associated to the disease, doctors can ask you to have some tests done. During emergencies,  a physical exam to review your medical history along with ECG or electrocardiogram inevitably becomes the first step to diagnose a heart attack.  To evaluate your heart function, the cardiologist might also use invasive procedures involving specialised medical equipment. TREATMENT The duration and the treatm ent  depend on your initial assessment.

It begins in the skin or in the tissue that covers the surface of internal organs and glands. It's the most common one. - Sarcomas. It begins in the tissues that support and connect the body. - Leukemias. It's a cancer of the blood, and it begins when healthy blood cells change and grow uncontrolably. - Lymphomas. It's a cancer that begins in the lymphatic system. There are other types of cancer (melanoma, brain and spinal cord tumors...). CAUSES Cancer cells develop because of multiple genetic changes in their genes. The causes of this changes could be: lifestyle habits, genes from your parents, and being exposed to cancer-causing agents. HOW DOES IT WORK? Cells grow and divide to create other cells as the body needs them. They die when they get to old or damaged, then new cells take their place. Cancer begins when cells start to grow uncontrollably, formin...
