How is palliative care different from hospice?
Unlike with hospice care, you can receive palliative care at any stage in your disease and continue to get treatments to cure it. You don't have to be dying or have a terminal illness to get palliative care.

What should I be monitoring while my child is on ADHD medication titration?
What works at first may not continue to over time. Watch your child for symptoms and side effects as he grows and his schedule and lifestyle change. Check in with the doctor every 3 months or so to make sure your child is still on the right treatment.
911e19179341e7eddc40878001c4db81
What side effects are associated with ADHD medication titration?
Common side effects include sleeping problems, appetite loss, and not feeling as social. These often go away after a few weeks, so your doctor may encourage you to wait it out and see if they get better on their own. If they don't, your doctor can adjust the dosage or change the medication. Less common but more serious side effects can include hallucinations, tics, and depression. You may want to start during the weekend or over a school break so you can keep a close eye on your child for the first few days. You can also use this time to figure out the best time to take the medicine.

When is the best time to start titration for ADHD medication in a child?
This is called titration. You may want to start during the weekend or over a school break so you can keep a close eye on your child for the first few days. You can also use this time to figure out the best time to take the medicine. For example, a younger child may need to take the medicine in the morning to focus throughout the school day, and a teen may need a stronger dose later in the afternoon to get through homework or to focus while driving home.

What is chest pain like as a symptom of a heart attack in men?
This is the most common symptom of a heart attack in both men and women. Most often, it starts slowly with mild pain or discomfort. A sudden onset of severe symptoms is sometimes called a “ Hollywood heart attack,” because of the typical way heart attacks have been portrayed in movies and television. A heart attack can happen this way, but it doesn't that often.

How long are patients with acute disseminated encephalomyelitis (ADEM) hospitalized?
The goal is to get the inflammation down quickly and stop the immune system attack. This will likely take a week or two in the hospital.
82225769070d7c82c0e17237b81ac72b
What are the best therapies for acute disseminated encephalomyelitis (ADEM)?
After the hospital, they may need some combination of physical, occupational, and speech therapy. They may have to stay in a rehab hospital for a while, or maybe they can go home and work with a therapist.
2b3cc6a3f408bf8425b153c147da9f0b
What causes acute disseminated encephalomyelitis (ADEM)?
Other symptoms include: Fever Headache Sleepiness Behavior changes such as fussiness or confusion Nausea and vomiting Seizures Coma ADEM seems to be an autoimmune disease. That means your immune system attacks your body's own cells and tissues as if they were outside bacteria or viruses.
b7a6fde1eb2a9c1f9b6640c9518342a2
What triggers acute disseminated encephalomyelitis (ADEM)?
Experts don't know exactly what triggers it, but it could be an overreaction to an infection. Most of the time, the attack happens when a child is getting over some common illness, like a cold or stomach bug. ADEM sometimes follows an immunization, particularly certain rabies shots and the vaccine for measles, mumps, and rubella. No direct connection has been made though. Other times, nothing out of the ordinary happens before symptoms appear.
68b6c459de79be5f71440fe368b99b1f
What is the treatment for acute disseminated encephalomyelitis (ADEM) in children?
Most people start with high doses of a powerful corticosteroid by IV for a few days. Your child may feel better within hours. They'll continue to take a steroid (as a pill or a liquid) for several weeks, in smaller and smaller doses. If your child can't have steroids or if they don't work, some procedures can calm the immune system. The doctor may filter their blood through a machine to remove the antibodies that their immune system is sending to attack the brain. This is called plasmapheresis. Or they could get shots of antibodies from a healthy person, which is called intravenous immunoglobulin treatment.

What is acute disseminated encephalomyelitis (ADEM)?
ADEM is a rare kind of inflammation that affects the brain and spinal cord. It damages the protective coating of nerve fibers, called myelin. Most often, children under age 10 will get it. While symptoms can be severe, they can be treated. Most people make a full recovery and don't have another attack.
8222fb0245bf264257fdc03ddaaab28b
How is acute disseminated encephalomyelitis (ADEM) diagnosed in kids?
But MS is rare in children. Other differences can also help your doctor make the right diagnosis. Kids with ADEM may have a fever, a headache, seizures, or trouble thinking clearly. The disease usually appears soon after a viral illness. There's no such link with MS. An ADEM attack usually happens once, while multiple sclerosis involves many episodes over time. Tests of spinal fluid usually show certain proteins when you have MS, but not ADEM. With ADEM, spinal fluid usually has more white blood cells than normal. Damage to the brain from ADEM and damage caused by multiple sclerosis look different on an MRI. It's more widespread with ADEM. The doctor has to rule out other illnesses with similar symptoms, too, like infections of the brain and spinal cord such as meningitis.
dcb810df3de1669c96797596cca04ac6
What is the outlook for acute disseminated encephalomyelitis (ADEM)?
Most of the time, a child who gets ADEM will recover completely. It will be a slow process, over 4 to 6 weeks. But it could be 6 months or up to a year before they're fully well. In some cases, kids don't get over all of their symptoms. They may have lasting vision damage or muscle weakness. They might have trouble in school if they've missed a lot of time, or perhaps as a lingering effect of the attack. About 8 times out of 10, ADEM happens only once. But sometimes you can get it again within a few months, especially if you don't take steroids for long enough. Your child might get MS later, but it's unlikely. In very rare cases, ADEM can be fatal.
dbb177fd0f77b58fafdb4453bce4ad49
Does therapy for acute disseminated encephalomyelitis (ADEM) usually continue after hospitalization?
After the hospital, they may need some combination of physical, occupational, and speech therapy. They may have to stay in a rehab hospital for a while, or maybe they can go home and work with a therapist. Your child's doctor will probably want a follow-up MRI to make sure the inflammation is gone and no new scars have formed.
9bca6fa6c6afd11a43d739876e15929c
How is acute disseminated encephalomyelitis (ADEM) differentiated from other conditions with similar symptoms?
The condition has a lot in common with multiple sclerosis and other diseases that damage myelin. They share some symptoms, like muscle weakness, numbness, loss of vision, and loss of balance. But MS is rare in children. Other differences can also help your doctor make the right diagnosis. Kids with ADEM may have a fever, a headache, seizures, or trouble thinking clearly. The disease usually appears soon after a viral illness. There's no such link with MS. An ADEM attack usually happens once, while multiple sclerosis involves many episodes over time.

Who gets oral cancer?
It's estimated that over 50,000 people in the U. S. received a diagnosis of oral cancer in 2019. Risk factors for the development of oral cancer include: Smoking . Cigarette, cigar, or pipe smokers are six times more likely than nonsmokers to develop oral cancers. Smokeless tobacco users. Users of dip, snuff, or chewing tobacco products are 50 times more likely to develop cancers of the cheek, gums, and lining of the lips. Excessive consumption of alcohol. Oral cancers are about six times more common in drinkers than in nondrinkers. Family history of cancer. Excessive sun exposure, especially at a young age. Human papillomavirus ( HPV). Certain HPV strains are etiologic risk factors for Oropharyngeal Squamous Cell Carcinoma ( OSCC). The American Cancer Society recommends oral cancer screening exams every 3 years for persons over age 20 and annually for those over age 40.

How is oral cancer diagnosed?
A biopsy may be needed to determine the makeup of a suspicious looking area. There are different types of biopsies and your doctor can determine which one is best. Many doctors don't use brush biopsies because while they're very easy, they still need a scalpel biopsy to confirm the results if the brush biopsy is positive. Also there are different types of scalpel biopsies, incisional and excisional, depending whether only a piece or the whole area is needed to determine what the nature of the problem is. Some doctors perform these biopsies with lasers. Feel for lumps or enlarged lymph nodes in both sides of your neck and under your lower jaw. Call your dentist's office immediately if you notice any changes in the appearance of your mouth or any of the signs and symptoms mentioned above. During your next dental appointment, ask your dentist to perform an oral exam.

How do you make memories?
For something to become a memory, three functions must occur, including: Acquisition -- learning or experiencing something new Consolidation -- the memory becomes stable in the brain Recall -- having the ability to access the memory in the future Both acquisition and recall are functions that take place when you are awake. However, researchers believe sleep is required for consolidation of a memory, no matter the memory type.
533b1843243f9763573763bb17c5e112
What happens when you sleep?
Scientists don't know exactly how sleep enhances memory, but it appears to involve the brain's hippocampus and neocortex -- the part of the brain where long-term memories are stored. It is thought that during sleep, the hippocampus replays the events of the day for the neocortex, where it reviews and processes memories, helping them to last for the long term.
3dcb7722f7fab482f55165da8facffb0
What does sleep affect?
Studies show that sleep affects physical reflexes, fine motor skills, and judgment, too. One study showed that participants who were sleep deprived were more likely to think they were right when they were, in fact, wrong. Studies involving memory tests show that after a single night of sleep, or even a nap, people perform better, whether on a test, in the office, on the athletic field, or in a concert hall.
e266f8ffbceb71c08f80074e6930bde3
Why is sleep important for memory?
Imaging and behavioral studies continue to show the critical role sleep plays in learning and memory. Researchers believe that sleep affects learning and memory in two ways: Lack of sleep impairs a person's ability to focus and learn efficiently. Sleep is necessary to consolidate a memory (make it stick) so that it can be recalled in the future.

What are tips to help you get more sleep?
Here are some tips to help you get more sleep: Go to sleep and wake up at the same time each day. Get regular exercise, but do not exercise close to bedtime. Experts recommend allowing at least three hours between exercise and bed. Avoid caffeine, alcohol, and nicotine before going to sleep. Take time to unwind before going to sleep. Take a warm bath, read a book, drink some caffeine-free tea, and avoid any activities that can cause tension. Finish eating two to three hours before going to bed. Create a pleasant sleeping environment: make the room dark, cool, and comfortable. Use a sound machine, or other type of white noise device, to block out unwanted sounds. Do not watch TV or use the computer in bed. Use your bedroom for sleep and sex only. Maintaining a healthy lifestyle, including getting regular and quality sleep, can be a challenge, especially when you are stressed with a work deadline or test. But, remember (and you need sleep to do this! ), sleep is your friend. So, when it comes to learning and memory, sleep on it.

How often should you check your blood sugar if you're pregnant?
How often should you check your blood sugar? Pre-existing diabetes: Before and after meals and before bedtime Gestational diabetes: Before breakfast and after every meal; your doctor can tell you how long after eating you should check. If you are pregnant and have type 1 diabetes, your doctor might sometimes ask you to check your blood sugar in the middle of the night, around 3 a.m.

Why is it important to continually check blood sugar levels if you are pregnant with diabetes?
Tight control will help you avoid complications and long-term health problems for both you and your baby. You're eating differently because your body needs more energy to help your baby grow and be healthy. And your changing hormones affect how your body makes and uses insulin. In the later parts of your pregnancy, you may become more insulin resistant, so blood sugar builds up to higher levels. If you are pregnant and have type 1 diabetes, your doctor might sometimes ask you to check your blood sugar in the middle of the night, around 3 a.m.

What is the vitreous in the eye?
It's bathed in moisture from a clear jelly known as the vitreous.

What is the retinal pigment epithelium (RPE) in the eye?
These cells absorb excess light so the photoreceptors can give a clearer signal. They also move nutrients to (and waste from) the photoreceptors to the choroid. The choroid is separate from the RPE.

What are photoreceptors?
They're special nerve endings that convert the light into electrochemical signals.

Where does the light that enters the eye go?
Its final destination is the retina, which lines the back of your eye. It's like the screen in a movie theater or the film in a camera. The focused light hits cells called photoreceptors.

How does the lens of the eye work?
It circulates throughout the front part of your eye and keeps pressure inside constant After the aqueous humor, light passes through the pupil. This is the central round opening in your iris, the colored part of your eye. It changes size to control how much light gets in farther back. Next up is the lens. It works just like a camera to focus light. It adjusts shape depending on whether the light reflects off something near to you or far away.

What is the retinal pigment epithelium (RPE), choroid, and sclera in the retina?
These cells absorb excess light so the photoreceptors can give a clearer signal. They also move nutrients to (and waste from) the photoreceptors to the choroid. The choroid is separate from the RPE. It lies behind the retina and is made up of many fine blood vessels that supply nutrition to the retina and the RPE. Sclera is the tough, white, fibrous outside wall of your eye. It's connected to the clear cornea in front.

What are the blood vessels, macula, and photoreceptors in the retina?
Unlike a movie screen, the retina has many parts: Blood vessels bring nutrients to your nerve cells. The macula is the bull's-eye at the center of your retina. The dead center is called the fovea. Because it's the focal point of your eye, it has more special, light-sensitive nerve endings, called photoreceptors, than any other part. Photoreceptors come in two kinds: rods and cones. They're special nerve endings that convert the light into electrochemical signals.

How do our eyes work?
The first thing it touches is a thin veil of tears in the front. Behind this is your eye's front window, the cornea. This clear layer helps focus the light. On the other side is liquid called the aqueous humor. It circulates throughout the front part of your eye and keeps pressure inside constant After the aqueous humor, light passes through the pupil. And that's how you see: Light, reflected from an object, enters the eye, gets focused, is converted into electrochemical signals, delivered to the brain, and is interpreted, or "seen," as an image.

Is having a hard time concentrating and being forgetful a normal part of perimenopause?
Unfortunately, difficulty with concentration and minor memory problems can often be a normal part of perimenopause, the time leading up to menopause (defined as not having a period for a year). The good news is that it is likely to be temporary. Current medical knowledge is limited as to why memory changes occur with perimenopause, and there are currently no treatments available to relieve these symptoms. If you are having memory problems, discuss this with your doctor. He or she can help manage memory problems or refer you to a provider who can.

Why does the weather trigger headaches and migraines?
As noted earlier, there is a theory that headaches triggered by extreme weather are a protective, or defensive, response because they lead the person to seek a more hospitable environment. Experts believe that people who get frequent headaches have a greater sensitivity to changes in the environment. They also have a lower threshold to the pain response. The reason, they suspect, is that people who get migraine headaches have likely inherited this sensitivity. The survey cited earlier also found that two out of three headache sufferers had not discussed environmental triggers with their doctors. Nearly half of them, though, had been plagued by headaches for more than 20 years.

What happens when testosterone levels rise in women?
If your body produces too much testosterone, you may have irregular or absent menstrual periods. You may also have more body hair than the average woman. Some women with high testosterone levels develop frontal balding. Other possible effects include acne, an enlarged clitoris, increased muscle mass, and deepening of voice. High levels of testosterone can also lead to infertility and are commonly seen in polycystic ovarian syndrome ( PCOS).
