As we age, many of us develop concerns about our memory, especially when it comes to figuring out what are normal “senior moments” versus what may be the beginning of a more serious memory disorder. Alzheimer’s disease and other forms of dementia are progressive neurodegenerative diseases that usually start off slowly and worsen over time, destroying memory and other mental functions.
The autonomic nervous system (ANS) controls automatic body functions such as heart rate, blood pressure, bowel, bladder and sexual function.
Autonomic dysfunction occurs when the nerves of the ANS are damaged. This can happen with diseases of the peripheral nervous system as well as diseases of the central nervous system. Diabetes and Parkinson’s disease are two examples of chronic conditions that can lead to autonomic dysfunction.
A brain aneurysm (or cerebral aneurysm) is a weak area on the wall of a brain artery that balloons out and fills with blood. This bulging pocket or sac can put pressure on other parts of the brain, which may or may not cause symptoms. In some cases the weakened blood vessel may burst (rupture or bleed), spreading blood into the surrounding tissue (called a hemorrhage).
Not all brain aneurysms burst or cause symptoms. Approximately 6 million people in the United States (about 1 in 50) are living with an unruptured brain aneurysm. However, nearly one third of those who have a ruptured brain aneurysm will die as a result, and more than half who survive will have some permanent disability.
Brain tumors can be benign (non-cancerous) or malignant (cancerous), but both types are serious conditions that require immediate attention and expert treatment. Brain tumor treatment options vary significantly depending on the specific type of brain tumor and the stage of the disease.
Dystonia is a movement disorder that causes muscles to contract uncontrollably and lead to abnormal postures. Dystonia affects about 1% of the population and is more common in women than men. Dystonia can affect different body parts and often the symptoms of dystonia progress through stages.
Epilepsy is a chronic neurological disorder marked by recurrent, unprovoked seizures. Epilepsy is a common condition that may occur as a result of a genetic disorder or may be caused by a traumatic brain injury.
A headache is pain or discomfort in the head or face. Headaches can vary in terms of their location, intensity of pain and how frequently they occur. A migraine is a type of headache that includes symptoms other than pain. These may include nausea, lightheadedness and sensitivity to light.
Huntington’s disease (HD) is an inherited genetic disorder that causes the progressive breakdown of nerve cells in the brain and deteriorates a person’s physical and mental abilities. It has no cure. Most people with HD develop signs and symptoms in their 30s or 40s, but symptoms of the disease may appear earlier or later in life. Children of a parent with HD have a 50/50 chance of carrying the faulty gene.
Multiple Sclerosis (MS) is a disease of the central nervous system that disrupts the flow of information within the brain, and between the brain and body. Early MS symptoms include weakness, tingling, numbness, pain, fatigue and blurred vision. Women are at a higher risk for MS than men.
Neck pain is very common. There are many complex and important structures in the neck, including the top seven bones in the spine (vertebrae), the disks between the vertebrae, blood vessels, spinal nerves, muscles and ligaments. Problems with any one of these can result in neck pain. If neck pain is chronic, and doesn't improve with neck exercises or ergonomics, your options might include injections or radiofrequency treatments.
Parkinson’s disease affects an estimated 1.5 million Americans, men and women of all ages and races. It is a slowly progressive movement disorder that occurs when a significant number of certain nerve cells in the brain become damaged or die.
Restless leg syndrome is a disorder of the nervous system that causes a strong or sometimes uncontrollable urge to move your legs. Symptoms usually occur at night and can be most severe when you are sitting or lying down.
Sciatica is the sensation of pain along the sciatic nerve, which runs through the lower back, buttocks and down each leg. Most patients who experience sciatica only have pain on one side of their body.
Sleep disorders are a group of conditions that affect your ability to sleep long enough and get good quality sleep on a regular basis. Many people experience occasional sleep problems, but when sleep issues occur on a regular basis, you should talk with your care provider to find out more about a possible sleep disorder.
Trigeminal Neuralgia is a chronic pain condition that affects the trigeminal nerve, which carries sensation from your face to your brain. Usually, this condition occurs when a blood vessel (artery or vein) and the trigeminal nerve at the base of your brain make contact. This contact puts pressure on the nerve and causes it to malfunction.
