Translational Neuroscience of Excessive Daytime Sleepiness (EDS), Fatigue and Hypersomnia.
Translational Neuroscience of Excessive Daytime Sleepiness (EDS), Fatigue and Hypersomnia. Mohammad Torabi Nami 5,421 Views • 3 years ago

M.Torabi Nami MD, PhDc Department of Neuroscience Institute for Cognitive Science Studies (ICSS), Tehran 15948 Iran Torabi_m@iricss.org Abstract 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 “hypersom

Living with Lewy Body Dementia - Mayo Clinic
Living with Lewy Body Dementia - Mayo Clinic samer kareem 1,837 Views • 3 years ago

LBD is not a rare disease. It affects an estimated 1.4 million individuals and their families in the United States. Because LBD symptoms can closely resemble other more commonly known diseases like Alzheimer’s and Parkinson’s, it is currently widely underdiagnosed. Many doctors or other medical professionals still are not familiar with LBD. LBD is an umbrella term for two related diagnoses. LBD refers to both Parkinson’s disease dementia and dementia with Lewy bodies. The earliest symptoms of these two diseases differ, but reflect the same underlying biological changes in the brain. Over time, people with both diagnoses will develop very similar cognitive, physical, sleep, and behavioral symptoms. While it may take more than a year or two for enough symptoms to develop for a doctor to diagnose LBD, it is critical to pursue a formal diagnosis. Early diagnosis allows for important early treatment that may extend quality of life and independence. LBD is a multisystem disease and typically requires a comprehensive treatment approach. This approach involves a team of physicians from different specialties who collaborate to provide optimum treatment of each symptom without worsening other LBD symptoms. Many people with LBD enjoy significant improvement of their symptoms with a comprehensive approach to treatment, and some can have remarkably little change from year to year. Some people with LBD are extremely sensitive or may react negatively to certain medications used to treat Alzheimer’s or Parkinson’s in addition to certain over-the-counter medications.

Strep Throat to Rheumatic Heart Disease
Strep Throat to Rheumatic Heart Disease samer kareem 1,532 Views • 3 years ago

What causes rheumatic fever? Rheumatic fever is not an infection itself, but rather the result of an untreated strep infection. When your body senses the strep infection, it sends antibodies to fight it. Sometimes, these antibodies attack the tissues of your joints or heart instead. If the antibodies attack your heart, they can cause your heart valves to swell, which can lead to scarring of the valve "doors" (called leaflets or cusps). Who is at risk for rheumatic fever? Fewer than 0.3% of people who have strep throat also get rheumatic fever. Rheumatic fever is most common among children aged 5 to 15, but adults may have the condition as well. Doctors think that a weakened immune system may make some people more likely to get rheumatic fever. And, although antibiotic medicines have reduced the number of cases of rheumatic fever in developed countries, there are still thousands of reported cases. What are the symptoms of rheumatic fever and how is it diagnosed? Symptoms of rheumatic fever usually begin 1 to 6 weeks after you have had a strep infection. They are Fever Joint pain or swelling in your wrists, elbows, knees, or ankles Small bumps under the skin over your elbows or knees (called nodules) A raised, red rash on your chest, back, or stomach Stomach pain or feeling less hungry Weakness, shortness of breath, or feeling very tired Your doctor will begin by doing a throat culture to find out if you have a strep infection. Then, your doctor will use a stethoscope to listen to your heart. He or she will also look for nodules on your joints. Sometimes, blood tests, chest x-rays, or an electrocardiogram (ECG or EKG) may be needed for a more definite diagnosis. How is rheumatic fever treated? Rheumatic fever must be treated right away. If you have a sore throat that lasts longer than 3 days, or if you have a fever and headache along with your sore throat, you should see your doctor for a throat culture. Even if you do not have a sore throat but have a fever and a skin rash, this could also mean a strep infection, and you should get tested. Remember rheumatic fever can result from an untreated strep infection, so it is very important to treat the infection before it leads to a worse condition.

Migraine Treatment
Migraine Treatment samer kareem 2,914 Views • 3 years ago

Migraine treatments can help stop symptoms and prevent future attacks. Many medications have been designed to treat migraines. Some drugs often used to treat other conditions also may help relieve or prevent migraines. Medications used to combat migraines fall into two broad categories: Pain-relieving medications. Also known as acute or abortive treatment, these types of drugs are taken during migraine attacks and are designed to stop symptoms. Preventive medications. These types of drugs are taken regularly, often on a daily basis, to reduce the severity or frequency of migraines. Your treatment strategy depends on the frequency and severity of your headaches, the degree of disability your headaches cause, and your other medical conditions. Some medications aren't recommended if you're pregnant or breast-feeding. Some medications aren't given to children. Your doctor can help find the right medication for you

Guillain-Barré Syndrome
Guillain-Barré Syndrome samer kareem 3,020 Views • 3 years ago

Guillain-Barre (gee-YAH-buh-RAY) syndrome is a rare disorder in which your body's immune system attacks your nerves. Weakness and tingling in your extremities are usually the first symptoms. These sensations can quickly spread, eventually paralyzing your whole body. In its most severe form Guillain-Barre syndrome is a medical emergency. Most people with the condition must be hospitalized to receive treatment. The exact cause of Guillain-Barre syndrome is unknown. But it is often preceded by an infectious illness such as a respiratory infection or the stomach flu. There's no known cure for Guillain-Barre syndrome, but several treatments can ease symptoms and reduce the duration of the illness. Most people recover from Guillain-Barre syndrome, though some may experience lingering effects from it, such as weakness, numbness or fatigue.

Hematuria
Hematuria samer kareem 3,506 Views • 3 years ago

Seeing blood in your urine can cause anxiety. While in many instances there are benign causes, blood in urine (hematuria) can also indicate a serious disorder. Blood that you can see is called gross hematuria. Urinary blood that's visible only under a microscope is known as microscopic hematuria and is found when your doctor tests your urine. Either way, it's important to determine the reason for the bleeding. Treatment depends on the underlying cause.

Interventional Stroke
Interventional Stroke samer kareem 5,368 Views • 3 years ago

The management of acute ischemic stroke has advanced greatly over the past 2 decades. New interventions, including intravenous and endovascular treatment strategies, have evolved to recanalize arteries and salvage the ischemic brain. The evolution of interventional approaches to the treatment of acute stroke has been prompted by the limitations of intravenous therapy and intended to extend the treatment window, improve recanalization rates, and subsequently long-term clinical outcomes. The major techniques that have defined the current field of interventional acute stroke management and the relevant past and current data, and ongoing clinical trials on interventional stroke therapy will be reviewed. New issues, such as futile recanalization, and time to microcatheter, will also be discussed.
