Every year some 30 million Americans experience one or more migraine. Although it is a common condition, migraines are often confused with other types of headaches. A migraine is a very severe headache that occurs in episodes and are is often accompanied by other symptoms ranging from nausea and vomiting to light sensitivity and extreme fatigue. Not every headache, even a severe headache, can be classified as a migraine. But migraines may not always present in a typical manner and it is therefore sometimes difficult to differentiate a migraine from more common headaches like tension-type and cluster headaches.

As people are living longer, a number of chronic conditions that affect the brain are now being more frequently seen. Not all these conditions are isolated to the older age groups, but it is more likely to affect people over the age of 60 years. These conditions that are often confused and misunderstood in how it affects the brain structure and function. Some develop gradually while others strike suddenly with no previous warnings. The effects may be minimal in some instances and even reversible to some degree, while others can be severely debilitating and even life threatening depending on the nature of the condition.
Sciatica is one of the most common causes of lower back pain that extends down to the legs. It occurs due to compression of the root of the sciatic nerve as it emerges from the spinal cord. Depending on the cause, it can be a chronic condition that requires surgery. However, many people do not realize that not every case of sciatica is permanent. In fact sciatica can resolve on its own sometimes without even using any medication, let alone undergoing surgery. It depends on each individual case. But the fact is that simple home remedies and preventative measures can make a significant difference in easing symptoms and even leading to almost complete sciatica pain relief.
Alzheimer’s disease is the most common cause of dementia among seniors. Every person dreads having Alzheimer’s disease as they get older, especially if they have seen or lived with a loved one who had the condition. But the facts are that the risk is high in North America in particular. Up to 10% of people older than 65 years will develop Alzheimer’s disease and there are some 5.4million people with the disease in the United States. As yet there is no known measure to completely prevent Alzheimer’s disease nor cure it, although there is hope that ongoing research will eventually reveal the ‘silver bullet’ at some point.
However, there are a host of risk factors that have been associated with Alzheimer’s disease. This means that having one or more of these factors increases your chances of developing Alzheimer’s disease. Some of the factors are modifiable – like your diet and lifestyle. Others are not – like your genes. Nevertheless, reducing your risk of developing Alzheimer’s disease and possibly preventing is at the very least better than trying to treat it once it has started.

Any nerve in the body can become compressed for a number of reasons. But it is often the nerves emanating from the spine that are the most prone. These spinal nerves have to pass out between the bones of the spine (vertebrae) to different parts of the body. It is at the root, as it passes out of the vertebral column, that these nerves are more likely to become compressed. Therefore this condition is referred to as nerve root compression (radiculopathy) or simply as a pinched back nerve. Compression affects the nerve’s function which is to carry signals to and from the spinal cord.
As a result there are a number of symptoms arise – abnormal sensations when sensory nerves are compressed or muscular symptoms when the motor nerves are compressed. Back symptoms are not always present. This means that you may not even have back pain yet there are nerve root compression symptoms present at different parts of the body, like the arms and hands or legs and feet. This can be misleading because the cause of the problem is at the back, and not at the location of the symptoms.
So how do you know if a nerve in your back is compressed or not?
A stroke, like a heart attack, is one of the most dreaded conditions. While there are other equally serious and life-threatening conditions, a stroke and heart attack are relatively common in the modern world. It is a major concern for people at risk but it can even strike a person who would otherwise seem like the most unlikely person to have a stroke or heart attack. And the most scary part is that there is no knowing exactly when it will strike. In an instant, life can change forever after having a stroke and sometimes even end altogether.
A meningioma is an abnormal growth (tumor) that arises from the protective lining around the brain and spinal cord, the meninges. These tumors can be benign (non-cancerous) or malignant (cancerous) with some being atypical where it is neither cancerous nor non-cancerous. The vast majority of meningiomas are benign. A meningioma means that the tumor arises from the cells that make up the meninges. It is possible for some cancers to spread to the meninges (metastasis) and result in a tumor at the site but this is not a meningioma. Although most meningiomas are benign, it still causes significant complications as it compresses the nerve tissue in the brain or spinal cord.
What is cubital tunnel syndrome?
Cubital tunnel syndrome is a condition where one of the main nerves of the arm, the ulnar nerve, becomes compressed or irritated at the point of the elbow. The ulnar nerve is a long nerve that can be damaged or diseased in any number of ways, broadly referred to as ulnar neuropathy, but cubital tunnel syndrome is a problem of the ulnar nerve at a specific site – at the elbow. It is often confused with a similar condition of the arm known as carpal tunnel syndrome which affects the median nerve as the wrist joint. In carpal tunnel syndrome, there is numbness and tingling of the little finger and a portion of the ring finger along with slight weakness of the grip.
What is neurogenic pulmonary edema?
Neurogenic pulmonary edema is a condition where fluid accumulates in the lungs after an injury to the brain, spinal cord and surrounding structures of the central nervous system. It can lead to serious and life threatening complications, and may even increase the risk of pulmonary infections. Pulmonary edema may occur for various reasons and neurogenic pulmonary edema is a specific type diagnosed when there is no other identifiable cause of fluid accumulation in the lungs.
What is piriformis syndrome?
Piriformis syndrome is a rare condition characterized by pain, instability, tingling and numbness in the lower back, buttocks, lower thighs and the calves. It arises due to the irritation or compression of the sciatic nerve by the piriformis muscle during running or sitting. The longest and widest nerve of the body, the sciatic nerve is prone to a number of conditions that can lead to pain, numbness and tingling along its path.
Piriformis syndrome is just one of these conditions that affects the sciatic nerve along its pat to the lower leg. The symptoms may be experienced along the entire course of the the sciatic nerve or in specific areas supplied by this nerve like the skin of the leg, the muscles of the thigh, leg and foot on the back side.
What is Pick disease?
Pick disease is a rare neurodegenerative disease that causes dementia or memory loss in patients. In a neurodegenerative disease, nerve cells (neurons) in the brain die and this results in irreversible damage. Pick disease results in aphasia (impaired ability to speak) and behavioral changes. This disorder affects emotional, social, and self-control skills of the patients. Unlike another similar brain condition known as Alzheimer’s disease, which affects individuals mostly after 50 years of age, Pick disease occurs in adults in their 40s. It affects men more often than women.
Ulnar Neuropathy Definition
Ulnar neuropathy refers to the condition in which one of the nerves in the forearm, known as the ulnar nerve, gets trapped or pinched. Pressure is applied on a nerve resulting in symptoms like pain, tingling, and numbness in parts of the forearm and hand. The term ulnar neuritis is often used interchangeably with ulnar neuropathy. However, neuritis specifically refers to inflammation of the nerve while neuropathy is an umbrella term for all disorders and diseases of the nerve.
Ulnar Neuropathy Location
The ulnar nerve is an important nerve in the arm and is responsible for movement of the forearm. It also provides sensation to the ring and small fingers, a part of the palm, and the hand. The ulnar nerve passes through many ligaments and may get trapped within it or by the bones of the upper extremity. Thickened ligaments or deformed or distorted bone are more likely to lead to nerve compression.
Meralgia Paresthetica Definition
Meralgia paresthetica refers to unusual sensations, particularly a burning pain or numbness, in the lateral part (outer side) of the thigh due to pressure on the lateral femoral cutaneous nerve (LFCN). In some cases, trauma, stretch injury and impaired circulation to the thigh may also contribute to pain and numbness in the thigh. Also called Bernhardt-Roth syndrome, meralgia paresthetica can affect people of all races and genders. Though it can affect people of all ages, meralgia paresthetica is more commonly seen during middle age. It affects about 4 to 5 out of every 10,000 people annually. Around 250 per 100,000 diabetic patients develop meralgia paresthetica.
Carpal Tunnel Syndrome Definition
Carpal tunnel syndrome is a condition where there is a tingling pain, numbness, and weakness of the thumb, index, and the middle fingers caused by irritation of the median nerve. It is a common condition in this day and age of excessive computer use and video gaming. The median nerve carries sensations from the thumb, index, and middle fingers of the hand. Along with some tendons, the median nerve passes through the carpal tunnel, which is located between wrist muscles and wrist bones. If there is a swelling or a change in position of the tissue inside the carpal tunnel, the median nerve is squeezed and irritated. This results in pain, numbness, and tingling.
Trigeminal Neuralgia Definition
Trigeminal neuralgia is defined as a painful condition involving irritation and inflammation of the trigeminal nerve. Trigeminal nerve carries sensation from the face to the brain. Trigeminal neuralgia, also called tic douloureux, causes unbearable facial pain on one side. Even the mildest activities can trigger this pain.
Trigeminal neuralgia starts with shorter, milder attacks but it soon changes into longer and frequent episodes of severe pain. The extent of pain is known to drive patients to the brink of suicide. The pain starts from trigeminal nerve and then spreads to the upper and lower jaws of one side of face. The pain may also cause a tic (facial spasm).
Sarcoidosis is a condition where the inflammatory cells of the body are active and grouping together as if is there is an infection despite the absence of any microbe. It is essentially a condition where the inflammatory response, that is intended to protect the body from injury, is active throughout the system for no apparent reason. When this condition affects the tissue of the nervous system – the brain, spinal cord and nerves – then it is known as neurosarcoidosis. Lesions known as granulomas form in the brain and nerves.
