Part 2: Translational Neuroscience of Excessive Daytime Sleepiness (EDS), Fatigue and Hype Mohammad Torabi Nami 8,881 Views • 2 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

This video, created by Nucleus Medical Media, shows a coronary artery bypass graft (CABG) procedure used to combat coronary artery disease. Beginning with a midline sternal incision, the heart is connected to a perfusion machine which will take over the duties of the heart while the surgery takes place. Two different grafts are used to bypass the blocked coronary arteries: the internal thoracic artery from inside the chest wall, and the saphenous vein from the leg. After the procedure, the heart is shocked to restart its beating. A drainage tube is left at the incision site to drain away excess fluid. The animation continues to show two other types of approaches to a coronary artery bypass graft, off-pump bypass surgery and minimally invasive bypass surgery.

This is similar to the procedure performed on former president Bill Clinton and former California governor Arnold Schwarzenegger.

Craniectomy brain surgery - 3D animation
Craniectomy brain surgery - 3D animation Surgeon 198 Views • 2 years ago

A brain surgery called a craniectomy is performed to remove a part of your skull in order to relieve pressure in an area when your brain swells from a traumatic brain injury. It is also performed to treat medical conditions that cause your brain to swell or bleed that can be caused by an aneurysm, brain tumor or other cancer.

This 3d animation shows how the surgical procedure decreases intracranial pressure (ICP), intracranial hypertension (ICHT), or heavy bleeding (also called hemorrhaging) inside your skull. If left untreated, pressure or bleeding can compress your brain and push it down onto the brain stem. This can be fatal or cause permanent brain damage.

Brain surgery is a very serious procedure under any circumstances, but a craniectomy is done when there is an immediate risk to the brain and neurological function due to severe brain injury or stroke.

Breast lumps facts Breast lumps can be caused by infections, injuries, non-cancerous growths, and cancer. Breast cancer usually causes no pain in the breast. The symptoms of breast cancer include painless breast lumps, nipple discharge, and inflammation of the skin of the breast. The chances that a particular breast lump could be cancerous depends on many factors, including past medical history, physical examination, as well as genetic and other risk factors. The only way to be certain that a lump is not cancerous is to have a tissue sampling (biopsy). There are several ways to do the biopsy. The treatment of a breast lump depends on its cause.

The Arthrex® Achilles SpeedBridge™ repair is a surgical technique system that combines fully threaded SwiveLock® anchors with FiberTape® suture. The surgeon may use the Achilles SpeedBridge to reattach the Achilles tendon to the heel bone after repairing the damaged portion of the Achilles tendon. The Achilles tendon connects the two large muscles at the back of the calf to the heel. Insertional Achilles tendinitis is a painful and disabling condition where the tendon attaches to the heel bone causing redness, pain and swelling. Patients who do not respond to the initial treatment may require surgical treatment.
