Alzheimer's disease is a progressive disease that destroys memory and other important mental functions. At first, someone with Alzheimer's disease may notice mild confusion and difficulty remembering. Eventually, people with the disease may even forget important people in their lives and undergo dramatic personality changes.

Alzheimer's disease is the most common cause of dementia — a group of brain disorders that cause the loss of intellectual and social skills. In Alzheimer's disease, the brain cells degenerate and die, causing a steady decline in memory and mental function.

Current Alzheimer's disease medications and management strategies may temporarily improve symptoms. This can sometimes help people with Alzheimer's disease maximize function and maintain independence for a little while longer. But because there's no cure for Alzheimer's disease, it's important to seek supportive services and tap into your support network as early as possible.

Breasts develop from embryological tissues, and the high estrogen level in females during puberty causes breasts to start growing bigger.

Breasts are mammary glands composed of layers of different types of tissue, including adipose, glandular and connective tissues. As these tissues have hormone receptors, there is often fluctuation in breast sizes and volumes based on hormonal changes in the body.

As breasts are considered a sign of femininity and beauty, women want their breasts to be perfectly shaped and sized. However, at times the breasts become larger in size, which can be due to several factors including genetics, obesity, pregnancy, breastfeeding, hormonal changes in the body and side effects of certain drugs.

A chalazion is a swollen bump on the eyelid. It happens when the eyelid’s oil gland clogs up. It may start as an internal hordeolum (stye). At first, you might not know you have a chalazion as there is little or no pain. But as it grows, your eyelid may get red, swollen, and sometimes tender to touch. If the chalazion gets large, it can press on your eye and cause blurry vision. Rarely, the whole eyelid might swell.

Dizziness: Painless head discomfort with many possible causes including disturbances of vision, the brain, balance (vestibular) system of the inner ear, and gastrointestinal system. Dizziness is a medically indistinct term which laypersons use to describe a variety of conditions ranging from lightheadedness, unsteadiness to vertigo.

Eczema is a common skin condition marked by itchy and inflamed patches of skin. It’s also known as atopic dermatitis. It is more common in babies and young children, and often occurs on the faces of infants. It also often appears inside the elbows and behind the knees of children, teenagers, and adults.
In rare cases, atopic dermatitis can first appear during puberty or adulthood. It affects males and females equally.

Eczema is a skin condition in which the skin of a person becomes dry, itchy, cracked and reddened. This chronic condition affects both males and females and mainly affects children. It is also known as atopic eczema or atopic dermatitis.  About 30 % of the skin diseases diagnosed will be eczema. Atopic eczema means inherited eczema.  It can occur in any part of the body and it is a long term disease. The intensity of the disease increases at some stages in the life and it needs intense treatment. Eczema can be triggered as an allergic response to various substances and situations.

A chalazion usually appears as a painless lump or swelling on your upper or lower eyelid. Chalazia may affect both upper and lower lids and can occur in both eyes at the same time. Depending on the size and location of the chalazion, it may blur or block vision.

Although not as common, a chalazion may be red, swollen, and painful if an infection is present.

There is more than one definition of frizz. Researchers who studied the perception of hair health found that while women around the world perceived the absence of frizz as a sign of healthy hair, how they described "frizz" varied widely according to hair type and desired style. As described by women in the study, the two main types of frizz are:

1. short strands sticking up at the part and throughout the hair length that "project away from the main body of hair"; this type is especially noticeable on women with straight hair who are trying to achieve a smooth style; and

2. strands of wavy or curly hair that do not align with others to form a defined wave or curl.[1]

By this definition, frizz is not exclusively a characteristic of curly hair; straight hair can be frizzy, and tightly curled or afro-textured hair can be frizz-free.[2] "Frizz" sometimes refers to curly hair in general, but that is not what most women understand the term to mean

It's normal to feel anxious from time to time, especially if your life is stressful. However, excessive, ongoing anxiety and worry that are difficult to control and interfere with day-to-day activities may be a sign of generalized anxiety disorder.

It's possible to develop generalized anxiety disorder as a child or an adult. Generalized anxiety disorder has symptoms that are similar to panic disorder, obsessive-compulsive disorder and other types of anxiety, but they're all different conditions.

Living with generalized anxiety disorder can be a long-term challenge. In many cases, it occurs along with other anxiety or mood disorders. In most cases, generalized anxiety disorder improves with psychotherapy or medications. Making lifestyle changes, learning coping skills and using relaxation techniques also can help.

Eczema is a condition where patches of skin become inflamed, itchy, red, cracked, and rough. Blisters may sometimes occur.Different stages and types of eczema affect 31.6 percent of people in the United States.The word "eczema" is also used specifically to talk about atopic dermatitis, the most common type of eczema.

Atopic" refers to a collection of diseases involving the immune system, including atopic dermatitis, asthma, and hay fever. Dermatitis is an inflammation of the skin.Some people outgrow the condition, while others will continue to have it throughout adulthood.This MNT Knowledge Center article will explain what eczema is and discuss the symptoms, causes, treatments, and types.

Fast facts on eczema

Here are some key points about eczema. More detail and supporting information is in the main article.

Certain foods can trigger symptoms, such as nuts and dairy.

Symptoms vary according to the age of the person with eczema, but they often include scaly, itchy patches of skin.

Eczema can also be triggered by environmental factors like smoke and pollen. However, eczema is not a curable condition.

Treatment focuses on healing damaged skin and alleviating symptoms. There is not yet a full cure for eczema, but symptoms can be managed.

Eczema is not a contagious condition.

Razor burn can affect any person who shaves part of their body. If you’ve ever had a red rash after shaving, you were likely experiencing razor burn.

Cuts: A cut is an area of severed skin that has been penetrated with a sharp edge, such as a knife, a small tool or the edge of a sheet of paper (paper cuts are also painful). The wound will often bleed and have slightly dehiscent wound edges.Grazes or abrasions: A usually harmless abrasion of the upper skin layers that occurs after falling on knees, hands or elbows, or scratching over a rough surface with some skin coming off subsequently. Abrasions can be painful since the injury often extends to the many fine nerve endings subjacent to the skin.

A grand mal seizure causes a loss of consciousness and violent muscle contractions. It's the type of seizure most people picture when they think about seizures.

A grand mal seizure — also known as a generalized tonic-clonic seizure — is caused by abnormal electrical activity throughout the brain. Usually, a grand mal seizure is caused by epilepsy. But sometimes, this type of seizure can be triggered by other health problems, such as extremely low blood sugar, a high fever or a stroke.

Many people who have a grand mal seizure never have another one and don't need treatment. But someone who has recurrent seizures may need treatment with daily anti-seizure medications to control and prevent future grand mal seizures.

Mittelschmerz is one-sided, lower abdominal pain associated with ovulation. German for "middle pain," mittelschmerz occurs midway through a menstrual cycle — about 14 days before your next menstrual period.In most cases, mittelschmerz doesn't require medical attention. For minor mittelschmerz discomfort, over-the-counter pain relievers and home remedies are often effective. If your mittelschmerz pain is troublesome, your doctor may prescribe an oral contraceptive to stop ovulation and prevent midcycle pain.

A febrile seizure is a convulsion in a child that may be caused by a spike in body temperature, often from an infection. Your child's having a febrile seizure can be alarming, and the few minutes it lasts can seem like an eternity.

Febrile seizures represent a unique response of a child's brain to fever, usually the first day of a fever. Fortunately, they're usually harmless and typically don't indicate an ongoing problem. You can help by keeping your child safe during a febrile seizure and by comforting him or her afterward.

Frozen shoulder is the common name for adhesive capsulitis, which is a shoulder condition that limits your range of motion. When the tissues in your shoulder joint become thicker and tighter, scar tissue develops over time. As a result, your shoulder joint doesn’t have enough space to rotate properly. Common symptoms include swelling, pain, and stiffness. You’re more likely to have the condition if you’re between the ages of 40 and 60.

You can also catch flu by touching an infected person, for instance, shaking hands. Adults are contagious 1-2 days before getting symptoms and up to 7 days after becoming ill. This means that you can spread the influenza virus before you even know you are infected.

In this article, we explain the symptoms of flu, how it is treated, how it differs from a cold, and the best ways to prevent flu occurring.

Shingles, also known as herpes zoster, is a viral disease characterized by a painful skin rash with blisters in a localized area.

Shingles is an infection caused by the varicella-zoster virus, which is the same virus that causes chickenpox. Even after the chickenpox infection is over, the virus may live in your nervous system for years before reactivating as shingles. Shingles may also be referred to as herpes zoster.

This type of viral infection is characterized by a red skin rash that can cause pain and burning. Shingles usually appears as a stripe of blisters on one side of the body, typically on the torso, neck, or face.

Most cases of shingles clear up within two to three weeks. Shingles rarely occurs more than once in the same person, but approximately 1 in 3 people in the United States will have shingles at some point in their life, according to the Centers for Disease Control and Prevention.

Zollinger-Ellison syndrome is a rare condition in which one or more tumors form in your pancreas or the upper part of your small intestine (duodenum). These tumors, called gastrinomas, secrete large amounts of the hormone gastrin, which causes your stomach to produce too much acid. The excess acid then leads to peptic ulcers, as well as to diarrhea and other symptoms.

Zollinger-Ellison syndrome (ZES) is rare. The disease may occur at any time in life, but people are usually diagnosed between ages 20 and 50. Medications to reduce stomach acid and heal the ulcers is the usual treatment for Zollinger-Ellison syndrome.

Zika (Zee-ka) virus disease is a mosquito-borne viral infection that primarily occurs in tropical and subtropical areas of the world. Most people infected with Zika virus have no signs and symptoms, while others report mild fever, rash and muscle pain. Other signs and symptoms may include headache, red eyes (conjunctivitis) and a general feeling of discomfort.

Zika virus infections during pregnancy have been linked to miscarriage and can cause microcephaly, a potentially fatal congenital brain condition. Zika virus also may cause other neurological disorders such as Guillain-Barre syndrome.

Researchers are working on a Zika virus vaccine. For now the best prevention is to prevent mosquito bites and reduce mosquito habitats.

Amblyopia, commonly known as lazy eye, is the eye condition noted by reduced vision not correctable by glasses or contact lenses and is not due to any eye disease. The brain, for some reason, does not fully acknowledge the images seen by the amblyopic eye. This almost always affects only one eye but may manifest with reduction of vision in both eyes. It is estimated that three percent of children under six have some form of amblyopia.

Schizoaffective disorder is a mental illness that involves persistent psychotic symptoms, like hallucinations or delusions, occurring together with mood problems of depressive, manic, or mixed episodes. The term schizoaffective was first used in 1933 by Jacob Kasanin and has been included in every edition of the mental health diagnostic manual, called the Diagnostic and Statistical Manual of Mental Disorders (DSM), since 1952. Statistics on how often this condition occurs range from 0.32% in the general United States population up to as much as 9% of psychiatrically hospitalized people. Schizoaffective disorder is thought to occur at least as often as schizophrenia and less often than 

Are you worried about your mental sharpness? Or maybe that of a loved one’s?

Mild forgetfulness can be a normal part of aging. If you have trouble remembering someone's name but it comes to you later, that's not a serious memory problem.

But if memory problems are seriously affecting your daily life, they could be early signs of Alzheimer's disease. While the number of symptoms you have and how strong they are vary, it’s important to identify the early signs. You need to ask yourself some tough questions.

ifferent stages and types of eczema affect 31.6 percent of people in the United States.

The word "eczema" is also used specifically to talk about atopic dermatitis, the most common type of eczema.

"Atopic" refers to a collection of diseases involving the immune system, including atopic dermatitis, asthma, and hay fever. Dermatitis is an inflammation of the skin.

Some people outgrow the condition, while others will continue to have it throughout adulthood.

This MNT Knowledge Center article will explain what eczema is and discuss the symptoms, causes, treatments, and types.

Schizoid personality disorder is an uncommon condition in which people avoid social activities and consistently shy away from interaction with others. They also have a limited range of emotional expression.

If you have schizoid personality disorder, you may be seen as a loner or dismissive of others, and you may lack the desire or skill to form close personal relationships. Because you don't tend to show emotion, you may appear as though you don't care about others or what's going on around you.

The cause of schizoid personality disorder is unknown. Talk therapy, and in some cases medications, can help.

People with schizotypal personality disorder are often described as odd or eccentric and usually have few, if any, close relationships. They generally don't understand how relationships form or the impact of their behavior on others. They may also misinterpret others' motivations and behaviors and develop significant distrust of others.

These problems may lead to severe anxiety and a tendency to turn inward in social situations, as the person with schizotypal personality disorder responds inappropriately to social cues and holds peculiar beliefs.

Schizotypal personality disorder typically is diagnosed in early adulthood and is likely to endure, though treatment, such as medications and therapy, can improve symptoms.

The features of seizures beginning in the temporal lobe can be extremely varied, but certain patterns are common. There may be a mixture of different feelings, emotions, thoughts, and experiences, which may be familiar or completely foreign. In some cases, a series of old memories resurfaces. In others, the person may feel as if everything – including home and family – appears strange. Hallucinations of voices, music, people, smells, or tastes may occur. These features are called “auras” or “warnings.” They may last for just a few seconds or may continue as long as a minute or two.Experiences during temporal lobe seizures vary in intensity and quality. Sometimes the seizures are so mild that the person barely notices. In other cases, the person may be consumed with fright, intellectual fascination, or even pleasure.The experiences and sensations that accompany these seizures are often impossible to describe, even for the most eloquent adult. And of course it is even more difficult to get an accurate picture of what people are feeling.

Zumba is an exercise fitness program created by Colombian dancer and cyclist/choreographer Alberto "Beto" "Power Pedal" Perez during the 1990s.[1] Zumba is a trademark owned by Zumba Fitness, LLC. The Brazilian pop singer Claudia Leitte has become the international ambassador to Zumba Fitness. Zumba involves dance and aerobic movements performed to energetic music. The choreography incorporates hip-hop, soca, samba, salsa, merengue and mambo. Squats and lunges are also included.[3] Zumba Fitness, the owner of the Zumba program, does not charge licensing fees to gyms or fitness centers.[4] Approximately 15 million people take weekly Zumba classes in over 200,000 locations across 180 countries

Angiotensin converting enzyme (ACE) participates in the renin cascade in response to hypovolemia. Its peptidase action on the decapeptide angiotensinogen I results in the hydrolysis of a terminal histidyl leucine dipeptide and the formation of the octapeptide angiotensin II, a potent vasoconstrictor that increases blood pressure.

The primary source of ACE is the endothelium of the lung. ACE activity is increased in sarcoidosis, a systemic granulomatous disease that commonly affects the lungs. In sarcoidosis, ACE is thought to be produced by epithelioid cells and macrophages of the granuloma.

Currently, it appears that ACE activity reflects the severity of sarcoidosis: 68% positivity in those with stage I sarcoidosis, 86% in stage II sarcoidosis, and 91% in stage III sarcoidosis. Serum ACE also appears to reflect the activity of the disease; there is a dramatic decrease in enzyme activity in some patients receiving prednisone.

Other conditions such as Gaucher disease, leprosy, untreated hyperthyroidism, psoriasis, premature infants with respiratory distress syndrome, adults with amyloidosis, and histoplasmosis have been associated with increased levels of ACE.

Visceral leishmaniasis (kala azar) is a disseminated intracellular protozoal infection that targets primarily the reticuloendothelial system (liver, spleen, bone marrow) and is caused by Leishmania donovani, Leishmania chagasi, or Leishmania infantum (Leishmania donovani complex).  Transmission is by the bite of sandflies. Clinical symptoms include fever, weight loss, and splenomegaly; pancytopenia and hypergammaglobulinemia are often present. Most (90%) new cases each year arise in rural areas of India, Nepal, Bangladesh, Sudan, and Brazil but the disease has a worldwide distribution, including the Middle East.  Definitive diagnosis has required the microscopic documentation of characteristic intracellular amastigotes in stained smears from culture of aspirates of tissue (spleen, lymph node) or bone marrow. The detection of serum antibodies to the recombinant K39 antigen of Leishmania donovani is an alternative noninvasive sensitive (95%-100%) method for the diagnosis of active, visceral leishmaniasis.

Lysozyme is a bacteriolytic enzyme that is found in some hematopoietic cells. It is primarily present in granulocytes, monocytes, and histiocytes. The enzyme is present in only minute amounts in lymphocytes; and is not present in myeloblasts, eosinophils, and basophils. Lysozyme in the plasma comes chiefly from the degradation of granulocytes and monocytes and its concentration reflects the turnover of these cells. Increases are seen in benign (eg, infection, inflammation) and malignant processes(eg, some leukemias). Plasma lysozyme is elevated in patients with acute or chronic granulocytic or monocytic leukemias and falls with successful treatment. Conversely, patients with lymphocytic leukemia may have depressed plasma lysozyme levels. Patients with renal disorders (including rejection of transplanted kidneys) or Crohn’s disease (regional enteritis) also tend to have elevated levels of plasma lysozyme.

Calcium is an important mineral that your body uses in many ways. It increases the strength of your bones and teeth and helps your muscles and nerves function.

A serum calcium blood test measures the total calcium in your blood. There are several different forms of calcium in your blood. These include ionized calcium, calcium bound to other minerals called anions, and calcium bound to proteins like albumin. Ionized calcium, also known as free calcium, is the most active form.

Magnetic Resonance Imaging is a highly advanced imaging modality. Epilepsy Protocol MRI involves obtaining images of brain slices through MRI scanning in epileptic patients. This scanning enables the doctor in obtaining evidences of abnormalities or injuries in brain. Underlying pathologies inside of brain like infections or tumors cannot be seen externally. Such occurrences can be investigated through an MRI Epilepsy Protocol. As a result, MRI becomes the most accurate mode for planning line of treatment.

A seizure happens because of abnormal electrical activity in the brain. It may go nearly unnoticed. Or, in some severe cases, it may cause unconsciousness and convulsions, when your body shakes uncontrollably. Seizures usually come on suddenly. How long and severe they are can vary. A seizure can happen to you just once, or over and over. If they keep coming back, that's epilepsy, or a seizure disorder. Less than one in 10 people who have a seizure get epilepsy.

For several decades, nonspecific methods, which depend upon raised globulin levels, have been used in the diagnosis of VL. Some of the tests used for detecting these nonspecific immunoglobulins are Napier's formol gel or aldehyde test and the Chopra antimony test. Since these tests depend upon raised globulin levels, results can be positive in a host of conditions (13, 14). Lack of specificity, as well as varying sensitivities, renders them highly unreliable.

Several immunodiagnostic methods which are more sensitive and specific have been developed. They are useful in identifying specific cases and can be used for community surveillance. The human body makes an attempt to fight against VL by producing some of the highest levels of antibodies found in response to any disease, all to no avail. This is due to polyclonal activation of the B cells, resulting in marked elevation of levels (in serum) of immunoglobulin G (IgG) and IgM against various nonspecific proteins and haptens (23). The consistent presence of high levels of antibodies against parasite antigens can simplify diagnosis of VL. Several serological techniques are based on detection of these antibodies. The specificity of the antibody depends upon the antigen or epitope used in the test, as the parasite stimulates production of a wide array of antibodies, including group-, genus-, and species-specific antibodies. Therefore, the sensitivity may depend upon the test and its methodology, but the specificity will depend on the antigen rather than the serological procedure used. In most serological tests, the sensitivity and specificity data are compared against demonstration of parasites in various tissues.
