Part 2: Translational Neuroscience of Excessive Daytime Sleepiness (EDS), Fatigue and Hype
Part 2: Translational Neuroscience of Excessive Daytime Sleepiness (EDS), Fatigue and Hype Mohammad Torabi Nami 8,929 Views • 3 years ago

Sleepiness, tiredness and fatigue are complaints which must be thoroughly analyzed to eliminate blur and ambiguity.
Physiological sleepiness (“sleep pressure”) increases while being awake and additionally underlies the circadian rhythm with a lower threshold to fall asleep during night time.
Excessive daytime sleepiness (EDS) is considered normal only after sleep deprivation. Clinically, EDS manifests by frequents daytime napping and/or reduced alertness with automatic behavior or - in its extreme form - in recurrent attacks of sudden, uncontrollable compulsion to sleep also in inappropriate situations (= “sleep attacks”).
EDS is “objectively” addressed by measuring the mean sleep latency to four to five nap opportunities throughout the day using the multiple sleep latency test (MSLT) or the maintenance of wakefulness test (MWT).
EDS denotes both, a ready entrance into sleep as well as difficulty in staying awake during daytime or accordingly in inappropriate situations. These two partially independent aspects of EDS are separately assessed by the “passive” MSLT and the “active” MWT respectively.
For that reason the MSLT and MWT only weakly correlate with each other when tested over a broad range of patients with EDS. It is important to keep in mind, that these tests are importantly influenced by a great variety of factors such as mood, anxiety, and motivation.
“Vigilance” comprises wakefulness, alertness and attention and therefore is more than just the reciprocal to sleepiness. Cognitive performance tasks such as Steer Clear Reaction Time Test (SCRTT) or driving simulators require the complete integrity of vigilance to achieve normal results. Hypersomnia is usually broadly defined as the combination of abnormally prolonged night-time sleep (regularly >10 h) with EDS during ≥1 months.
On the other hand, the term hypersomnia has also been used in a narrower scene for the isolated abnormality of a prolonged night-time sleep need (>10 h). “Tiredness”, also in colloquial language often used for sleepiness, in a broader sense also describes the feeling of lack of energy, motivation and initiative.

These patients seek rest rather than sleep. They often cannot fall asleep when given the opportunity in spite of feeling tired, and hence, in an MSLT, do not show an abnormally short sleep latency. Furthermore, tiredness (and fatigue) as opposed to sleepiness has a mental (“central”) and physiological (bodily or “peripheral”) component, which the patients can readily distinguish. Patients with insomnia, mild sleep apnea syndrome, or depression rather suffer from mental tiredness than sleepiness during the day.
The simple subjective self-assessment using the Epworth Sleepiness Scale (ESS) quite reliably differentiates between sleepiness and mental tiredness (without sleepiness), which makes it a widely used test. The term “fatigue” is also heterogeneously used.
In physiology the “fatigue” implied a “time on task performance decrement” to describe decreasing muscle force during a sustained physical effort. In clinical medicine one distinguishes physical (“peripheral”) from mental (“central”) fatigue and the term usually denotes a chronic and more abnormal situation than tiredness.
In a broad sense “fatigue” implies a deficiency in coping satisfactorily with mental and physical work load. The chronic fatigue syndrome entails both mental as well as a physical fatigue (so called “leaden paralysis” of limbs). Depressive states are often associated with insomnia and fatigue, but there are also cases with hypersomnia rather than insomnia ( non organic hypersomnia , “atypical depression” or “hypersomnolent depression”)
Sometimes these patients have a tendency to spend much of the day lying in the bed without actually sleeping (so called clinophilia). The basic and clinical aspects of fatigu

Eczema
Eczema samer kareem 1,711 Views • 3 years ago

Atopic dermatitis (eczema) is a condition that makes your skin red and itchy. It's common in children but can occur at any age. Atopic dermatitis is long lasting (chronic) and tends to flare periodically and then subside. It may be accompanied by asthma or hay fever.

Measles
Measles samer kareem 1,677 Views • 3 years ago

Measles is a childhood infection caused by a virus. Once quite common, measles can now almost always be prevented with a vaccine. Signs and symptoms of measles include cough, runny nose, inflamed eyes, sore throat, fever and a red, blotchy skin rash. Also called rubeola, measles can be serious and even fatal for small children. While death rates have been falling worldwide as more children receive the measles vaccine, the disease still kills more than 100,000 people a year, most under the age of 5. As a result of high vaccination rates, measles has not been widespread in the United States for more than a decade. Today, the United States averages about 60 cases of measles a year, and most of them originate outside the country.

Hypothyroidism
Hypothyroidism samer kareem 1,215 Views • 3 years ago

Hypothyroidism is a condition in which the body lacks sufficient thyroid hormone. Since the main purpose of thyroid hormone is to "run the body's metabolism," it is understandable that people with this condition will have symptoms associated with a slow metabolism. The estimates vary, but approximately 10 million Americans have this common medical condition. In fact, as many as 10% of women may have some degree of thyroid hormone deficiency. Hypothyroidism is more common than you would believe, and millions of people are currently hypothyroid and don't know it.

Keratitis
Keratitis samer kareem 2,445 Views • 3 years ago

Keratitis is an inflammation of the cornea — the clear, dome-shaped tissue on the front of your eye that covers the pupil and iris. Keratitis is sometimes caused by an infection involving bacteria, viruses, fungi or parasites. Noninfectious keratitis can be caused by a minor injury, wearing your contact lenses too long or other noninfectious diseases. If you have eye redness or other symptoms of keratitis, make an appointment to see your doctor. With prompt attention, mild to moderate cases of keratitis can usually be effectively treated without loss of vision. If left untreated, or if an infection is severe, keratitis can lead to serious complications that may permanently damage your vision.

Shoulder Cortisone Injections
Shoulder Cortisone Injections samer kareem 2,029 Views • 3 years ago

Corticosteroid Injections – Doctors sometimes inject corticosteroids directly into the knee joint for quick relief of pain and inflammation. Their benefits may last anywhere from a few days to more than six months. While the injections bring targeted relief to the joint and lack many of the side effects of oral corticosteroid medications, they are not without risks. Repeated knee injections may actually contribute to cartilage breakdown. For that reason your doctor will likely put a limit on the number of injections you can receive.

Catheter Ablation For Atrial Fibrillation
Catheter Ablation For Atrial Fibrillation samer kareem 2,471 Views • 3 years ago

Catheter ablation is a minimally invasive procedure to treat atrial fibrillation. It can relieve symptoms and improve quality of life. During an ablation, the doctor destroys tiny areas in the heart that are firing off abnormal electrical impulses and causing atrial fibrillation. You will be given medicine to help you relax. A local anesthetic will numb the site where the catheter is inserted. Sometimes, general anesthesia is used. The procedure is done in a hospital where you can be watched carefully. Thin, flexible wires called catheters are inserted into a vein, typically in the groin or neck, and threaded up into the heart. There is an electrode at the tip of the wires. The electrode sends out radio waves that create heat. This heat destroys the heart tissue that causes atrial fibrillation or the heart tissue that keeps it happening. Another option is to use freezing cold to destroy the heart tissue. Sometimes, abnormal impulses come from inside a pulmonary vein and cause atrial fibrillation. (The pulmonary veins bring blood back from the lungs to the heart.) Catheter ablation in a pulmonary vein can block these impulses and keep atrial fibrillation from happening. View a slideshow of catheter ablation to see how the heart's electrical system works, how atrial fibrillation happens, and how ablation is done. Atrial Fibrillation: Should I Have Catheter Ablation? AV node ablation AV node ablation is a slightly different type of ablation procedure for atrial fibrillation. AV node ablation can control symptoms of atrial fibrillation in some people. It might be right for you if medicine has not worked, catheter ablation did not stop your atrial fibrillation, or you cannot have catheter ablation. With AV node ablation, the entire atrioventricular (AV) node is destroyed. After the AV node is destroyed, it can no longer send impulses to the lower chambers of the heart (ventricles). This controls atrial fibrillation symptoms. After AV node ablation, a permanent pacemaker is needed to regulate your heart rhythm. Nodal ablation can control your heart rate and reduce your symptoms, but it does not prevent or cure atrial fibrillation. AV node ablation helps about 9 out of 10 people.1 The procedure has a low risk of serious problems.2 View a slideshow of AV node ablation to see how the heart's electrical system works, how atrial fibrillation happens, and how AV node ablation is performed.

Cervical Stenosis Cervical Spinal Stenosis Video Spinal stenosis pain in the neck is called cervical spinal stenosis. This condition means that there is potential compression of the spinal cord. Unfortunately, the spinal cord compression can lead to serious problems such as extreme weakness, or even paralysis. With cervical stenosis, anyone who develops signs of spinal cord compression (myelopathy) may need more invasive treatment, such as surgery.

Flu Virus samer kareem 2,275 Views • 3 years ago

There are two main types of influenza (flu) virus: Types A and B. The influenza A and B viruses that routinely spread in people (human influenza viruses) are responsible for seasonal flu epidemics each year. Influenza A viruses can be broken down into sub-types depending on the genes that make up the surface proteins. Over the course of a flu season, different types (A & B) and subtypes (influenza A) of influenza circulate and cause illness.

This video: Multiple myeloma is a cancer that forms in a type of white blood cell called a plasma cell. Plasma cells help you fight infections by making antibodies that recognize and attack germs. Multiple myeloma causes cancer cells to accumulate in the bone marrow, where they crowd out healthy blood cells. Rather than produce helpful antibodies, the cancer cells produce abnormal proteins that can cause kidney problems. Treatment for multiple myeloma isn't always necessary. If you're not experiencing signs and symptoms, you may not require treatment. If signs and symptoms develop, a number of treatments can help control your multiple myeloma.

Amoebic dysentery
Amoebic dysentery samer kareem 1,281 Views • 3 years ago

Dysentery is an infection of the intestines causing diarrhoea that contains blood or mucus. There are two main types of dysentery: Shigellosis, or bacillary dysentery, is the most common type experienced in the UK, caused by the shigella bacteria. Amoebic dysentery, also called amoebiasis, is caused by a single-celled parasite called Entamoeba histolytica. This form of dysentery is more common abroad in tropical countries. This article focuses on amoebic dysentery, This is usually caused by poor hygiene or contaminated food or water. Amoebic dysentery is a notifiable disease, so your GP must let the local health authority know if you have contracted it. Causes of amoebic dysentery Once inside the body, amoeba clump together to form a cyst that is protected by the stomach’s digestive acid. When the cyst passes through the intestines it breaks open infecting the body. The amoebae burrow into the intestinal wall and cause small ulcers or abscesses. Cysts exit the body via faeces but are still able to live outside, which is how many people become infected. Severe dysentery is more common in developing countries due to compromised hygiene. You can get sick in a number of ways including: Eating contaminated food Drinking contaminated water Contracting dysentery from another infected person. Symptoms of amoebic dysentery Symptoms can appear as many as 10 days after exposure and infection by the parasite. Signs of infection include: Watery diarrhoea with blood or pus in it Nausea or vomiting Stomach pain High temperature Chills Bleeding from back passage (rectum) Weight loss Loss of appetite. Complications of amoebic dysentery If the parasite gets into your bloodstream it can spread to other parts of your body, including the liver. When this happens you run the risk of developing a liver abscess. Symptoms include: High temperature Weakness Cough Jaundice Nausea Loss of appetite Weight loss
