Electromyography and Nerve Conduction Studies (EMG)

Electromyography (EMG) tests analyze nerve and muscle electrical activity. Some types of electrical activity are normal, whereas some patterns of electrical activity suggest a disease of nerves or muscles. Nerve conduction studies are tests that are often used in combination with the EMG evaluation. For nerve conduction studies, the muscles and nerves are stimulated with small bursts of electricity to see whether the nerves and muscles respond in a normal way. No preparation is necessary. For the EMG, thin needles are inserted one by one into the muscles being tested. These needles are not hollow, and they are thinner than the type of needle used to draw blood. Each needle is attached to a wire that gives signals to a machine. The needle acts like an antenna to detect electrical patterns inside the muscle and the nerves that are attached to that muscle. Most patients find this test mildly uncomfortable. (Locked) More »

New thinking on peripheral neuropathy

Doctors are learning that neuropathy can cause many more problems than just numbness and tingling in the feet and hands. Neuropathy of the autonomic nerves to the heart or blood vessels can cause low blood pressure, perceived as chronic fatigue and faintness or dizziness. Damage to nerve fibers serving the gastrointestinal tract may cause bloating, nausea, digestion problems, constipation, or diarrhea. These are often labeled irritable bowel syndrome. Autonomic neuropathy less often affects the bladder and sexual function. (Locked) More »

Poor sense of smell may predict risk of death in older adults

Shorter term studies have suggested a link between loss of smell among older adults and risk of death. A new report confirms that the association between loss of smell and earlier death persists over more than a decade and identifies the leading causes: cardiovascular disease, Alzheimer’s and Parkinson’s.

What could cause my sudden jaw pain?

Sudden jaw pain could be due to several conditions, including an irritated nerve, cluster headache, temporomandibular joint (TMJ) disorder, or a sign of cardiovascular disease. Since some of these involve immediate treatment, people should see their doctor to discuss their symptoms. (Locked) More »

Answers to the top questions about cannabis extract

Cannabidiol (CBD) is a non-intoxicating plant chemical that comes from hemp or marijuana. It is used to help reduce symptoms of many conditions, including anxiety, bipolar disorder, arthritis, diabetes, a muscle disorder called dystonia, seizures, multiple sclerosis, Parkinson’s disease, Crohn’s disease, chronic pain, post-traumatic stress disorder, and insomnia. CBD is considered generally safe and well tolerated, though it’s not clear yet how much CBD is safe and for how long, or if it is safe specifically for older adults. CBD has some known side effects and drug interactions. (Locked) More »

What is ALS?

ALS stands for amyotrophic lateral sclerosis, a terminal disease of the nerve cells that are involved in signaling muscles to move. Two medicines can slow but not stop the progression of the disease. (Locked) More »

What's causing your shaky hands?

Hand tremors may occur at rest (such as in Parkinson’s disease) or they may occur with activity. Resting tremors often look like one is rolling a pill between the thumb and index finger. Hand tremors that occur with activity may be postural (occurring when the hands are outstretched) or intentional (occurring when one is reaching for a target, such as a keyhole). Causes of tremors include caffeine use, an overactive thyroid, stress, fatigue, sleep deprivation, and medication side effects. More »

What causes my feet to suddenly become numb?

Q. My feet tingle or feel numb like they are asleep at times, mostly when I am in bed or with my legs elevated. What causes that? A. The symptoms you describe may be related to peripheral neuropathy, which is nerve damage that affects multiple nerves leading out from the spinal cord to the arms and legs. Symptoms are often equal in both feet. If only one foot, or part of a foot, is affected, this suggests compression of an individual nerve. Another possibility for foot tingling or numbness with leg elevation is poor circulation, but this is often accompanied by leg cramping while walking and color changes in the feet (pale or white when elevated, and red when lowered).
