Carpal Tunnel Syndrome Fact Sheet Treatments for carpal tunnel syndrome should begin as early as possible, under a doctor's direction. Underlying causes such as diabetes or arthritis should be treated first. Initial treatment generally involves resting the affected hand and wrist for at least 2 weeks, avoiding activities that may worsen symptoms, and immobilizing the wrist in a splint to avoid further damage from twisting or bending. If there is inflammation, applying cool packs can help reduce swelling. Non-surgical treatments Drugs - In special circumstances, various drugs can ease the pain and swelling associated with carpal tunnel syndrome. Exercise - Stretching and strengthening exercises can be helpful in people whose symptoms have abated. Alternative therapies - Acupuncture and chiropractic care have benefited some patients but their effectiveness remains unproved. Surgery Carpal tunnel release is one of the most common surgical procedures in the United States.

The carpal tunnel is the passageway in the wrist and consists of the arching carpal bones (eight bones in the wrist) and the ligament connecting the pillars of the arch (the transverse carpal ligament). Carpal tunnel syndrome occurs when the median nerve is compressed because of swelling of the nerve or tendons or both. While there are many possible causes of carpal tunnel syndrome, the vast majority of people with the condition have no known cause. What Are the Symptoms of Carpal Tunnel Syndrome? Usually, people with carpal tunnel syndrome first notice that their fingers "fall asleep" and become numb at night. Continue reading below... What Happens in Severe Cases of Carpal Tunnel Syndrome? As carpal tunnel syndrome becomes more severe, a person may have decreased grip strength with atrophy, or wasting, of the muscles in the hand.
Beta amyloid Amyloid-beta (Aβ or Abeta) denotes peptides of 36–43 amino acids that are crucially involved in Alzheimer's disease as the main component of the amyloid plaques found in the brains of Alzheimer patients. The peptides result from the amyloid precursor protein (APP), which is being cut by certain enzymes to yield Aβ. Aβ molecules can aggregate to form flexible soluble oligomers which may exist in several forms. It is now believed that certain misfolded oligomers (known as "seeds") can induce other Aβ molecules to also take the misfolded oligomeric form, leading to a chain reaction akin to a prion infection. The seeds or the resulting amyloid plaques are toxic to nerve cells. A recent study suggested that APP and its amyloid potential is of ancient origins, dating as far back as early deuterostomes.[3] Normal activity[edit] Disease associations[edit] Aβ is the main component of amyloid plaques (extracellular deposits found in the brains of patients with Alzheimer's disease).

heimer's Association - What Is Alzheimer's Alzheimer's and dementia basics Alzheimer's is the most common form of dementia, a general term for memory loss and other intellectual abilities serious enough to interfere with daily life. Alzheimer's disease accounts for 60 to 80 percent of dementia cases. Learn more: What We Know Today and Understanding Dementia. Get our weekly e-newsletter There is a lot to know about living with Alzheimer's disease. Alzheimer's is not a normal part of aging, although the greatest known risk factor is increasing age, and the majority of people with Alzheimer's are 65 and older.

Symptoms of Alzheimer's The most common early symptom of Alzheimer's is difficulty remembering newly learned information. Just like the rest of our bodies, our brains change as we age . People with memory loss or other possible signs of Alzheimer’s may find it hard to recognize they have a problem. Alzheimer's and the brain
Early-onset Alzheimer's disease Early-onset Alzheimer's disease, also called early-onset Alzheimer's, or early-onset AD, is the term used for cases of Alzheimer's disease diagnosed before the age of 65. It is an uncommon form of Alzheimer's, accounting for only 5-10% of all Alzheimer's cases. Approximately 13% of the cases of early-onset Alzheimer's are Familial Alzheimer's disease,[1] where a genetic predisposition leads to the disease. The other incidences of early onset Alzheimer's, however, share the same traits as the 'late onset' form commonly referred to as "Alzheimer's disease", and little is understood about how it starts. Non-Familial early onset Alzheimer's can develop in people who are in their thirties or forties, but that is extremely rare.[2] The majority of people with early-onset Alzheimer's are in their fifties or early sixties.

Welcome to Android - PCWorld By now, you've probably heard an earful about how great Android phones are, how they will take over the mobile world, and how they do everything the Apple iPhone can't. But if you haven't yet fully explored an Android phone, you may be wondering what the hype is all about. First, a little history: Google's move into the mobile phone market started way back in 2005, when the Internet giant acquired a small startup company called Android, Inc. Rumors immediately began to surface that Google was developing its own challenge to the iPhone. But it wasn't just one phone--and Google wasn't the only company working on the project. In November 2007, the Open Handset Alliance--a consortium of 47 hardware, software, and telecom companies--unveiled Android, a mobile platform based on the open-source Linux operating system. Because Android is open-source, the platform has many advantages for consumers and developers. And of course, you also have considerable freedom in selecting a wireless network.
Tau protein Tau proteins (or τ proteins, after the Greek letter by that name) are proteins that stabilize microtubules. They are abundant in neurons of the central nervous system and are less common elsewhere, but are also expressed at very low levels in CNS astrocytes and oligodendrocytes.[1] Pathologies and dementias of the nervous system such as Alzheimer's disease can result when tau proteins become defective and no longer stabilize microtubules properly. The tau proteins are the product of alternative splicing from a single gene that in humans is designated MAPT (microtubule-associated protein tau).[2][3] They were discovered in 1975 in Marc Kirschner's laboratory at Princeton University.[4] Function[edit] Tau protein is a highly soluble microtubule-associated protein (MAP). In humans, these proteins are found mostly in neurons compared to non-neuronal cells. Tau proteins interact with tubulin to stabilize microtubules and promote tubulin assembly into microtubules.

Neurons, Synapses, Action Potentials, and Neurotransmission ... Return to MODULE PAGE Neurons, Synapses, Action Potentials, and Neurotransmission Robert Stufflebeam: Author, Artist & Animator Functions of Neurons The central nervous system [CNS] is composed entirely of two kinds of specialized cells: neurons and glia. Neurons are the basic information processing structures in the CNS. While we are considering numbers, it is worth noting that there are as many as 50 times more glia than neurons in our CNS! Because our main interest lies in exploring how information processing occurs in the brain, we are going to ignore glia. Structure of neurons While there are as many as 10,000 specific types of neurons in the human brain, generally speaking, there are three kinds of neurons: motor neurons (for conveying motor information), sensory neurons (for conveying sensory information), and interneurons (which convey information between different types of neurons). A "typical" neuron has four distinct parts (or regions). Neuronal signaling Conduction
Brain Explorer 10 Brilliant Social Psychology Studies | PsyBlog Ten of the most influential social psychology experiments explain why we sometimes do dumb or irrational things. “I have been primarily interested in how and why ordinary people do unusual things, things that seem alien to their natures.Why do good people sometimes act evil?Why do smart people sometimes do dumb or irrational things?” –Philip Zimbardo Like famous social psychologist Professor Philip Zimbardo (author of The Lucifer Effect: Understanding How Good People Turn Evil), I’m also obsessed with why we do dumb or irrational things. The answer quite often is because of other people — something social psychologists have comprehensively shown. Each of the 10 brilliant social psychology experiments below tells a unique, insightful story relevant to all our lives, every day.
