Some issues Dr. Warren Orrin Ferris, MD can help you with:

Cognitive-Behavioral Therapy (CBT)

Cognitive-behavioral therapy, or CBT, is a form of psychotherapy or treatment for mental illness. It comes in a variety of methods, but the basic concept behind all CBT is the same -- thoughts cause feelings, which cause actions. If someone wishes to change problematic behaviors or emotions in their lives, they need to start by changing their thoughts. CBT examines ideas and looks for patterns that may be causing harmful actions. The therapist helps patients modify those thought patterns and, in doing so, helps them feel better and cope more effectively.

CBT is one of the most widely studied forms of psychotherapy, and it has been shown to be extremely effective for a variety of mental illnesses. Some of the issues that respond well to CBT include mood disorders, personality disorders, eating disorders, substance abuse, sleep disorders, and psychotic disorders. In some cases, CBT has been shown to be as effective or even more effective than medication. One of the interesting things that the scientific study of CBT has shown is that CBT actually changes the way the brain works, physically improving its function.

CBT differs from traditional psychotherapy in a few key ways. One of the most important distinctions is the emphasis on the power and responsibility of the patient in CBT. The patient will be encouraged to be the one asking the questions in CBT therapy, and most patients are assigned homework to complete outside of therapy sessions. There is a concept in CBT that everyone has power the power to change how they feel, even if they cannot control the situation, and this can be very empowering for patients. Because of this power shift, the therapist-client relationship is not as critical to success in CBT as it is in other modes of therapy. Patients should still get along well with their therapists, but they do not need a deep, dependent emotional connection to them. Finally, because CBT often treats a specific issue or problem, it is usually shorter in duration than traditional therapy. While some therapies may continue for years, CBT lasts on average just 16 sessions.

Musculoskeletal Problems

The musculoskeletal system refers collectively to the bones, joints, ligaments, muscles, and nerves. It is what gives the body structure and movement. Because this system encompasses so much of the body, musculoskeletal problems are extremely varied and can happen almost anywhere. There are musculoskeletal problems that affect only the joints, those that affect the bones, those that affect tendons and ligaments, and those that can happen in any area of the body but cause pain and numbness.

Joint problems include bursitis and arthritis. Bursitis is the inflammation of a fluid-filled sac cushion on the outside of a joint, causing symptoms including pain and swelling. Arthritis is the inflammation and damage of a joint due to wear and tear or disease. There are several treatments for arthritis, but if the damage progresses far enough, joint replacement may be necessary. In joint replacement, a metal or plastic implant is surgically placed within the joint to make movement easier.

Bone problems include scoliosis, fractures, and osteoporosis. Scoliosis is a curvature of the spine, making the normally straight spine look like a 'C' or 'S.' It is treated with braces or surgery. Osteoporosis is a disease that causes bones to weaken and break easily. It's most common in women, especially older women. Fully half of all women over 65 have osteoporosis. Fractures are any break in the bone. They can be a simple crack or a severe and complicated shatter. Osteoporosis causes fractures in people who have it, but other causes are trauma (such as a fall) or overuse.

Tendon and ligament problems most often result from injury or overuse. Two good examples are ligament tears and tendonitis. The most common ligament tear is the ACL tear in the knee. This ligament supports and stabilizes the knee and is most often torn during sports activities. Tendonitis happens when a tendon, which connects muscles and bones together, becomes irritated and inflamed. This happens most often in older patients who push their bodies too far, leading to pain and swelling. Treatment for both tendon and ligament problems usually includes rest, ice, and supporting the area to let it heal.

Pain and numbness problems can be caused by overuse, disease, an injury, or a compressed nerve. Lower back pain and carpal tunnel syndrome are two of the most common conditions patients encounter. Lower back pain may be caused by sore muscles that have been overworked, or an injury to the disks separating the vertebrae in the spine. Lower back pain usually goes away on its own within a few days, but it may require medical treatment depending on the cause. Carpal tunnel syndrome occurs when the nerve at the base of the palm becomes trapped or pinched. Symptoms include tingling, pain, numbness, or weakness in the hand. Treatment involves rest and sometimes steroid injections.

Because the musculoskeletal system involves so much of the body, problems here can be incredibly varied in their type and severity. Some musculoskeletal problems will go away on their own or only require rest, while others may require medication, physical therapy, or even surgery.

Nutrition Counseling

Food is one of the most basic resources the human body uses for growth and energy, tied intricately to well-being. Not only can diet affect health, but certain conditions can affect how the body processes food. Nutrition is the study of this complex interaction, and when patients seek the advice of an expert to help them manage food in their life, it is called nutrition counseling.

At the most basic level, nutrition counseling can be simply a talk with a family physician. Doctors receive training in nutrition as part of their education, and they are generally qualified to make recommendations about diet for their patients. Some doctors take a professional interest in nutrition and become experts by taking extra classes or studying nutrition in their practice. In general, however, complex nutrition guidance will be referred to a nutrition specialist, generally a dietitian.

Registered dietitians are nutrition experts that have passed specific higher education, accreditation, and internship requirements. They may work in hospitals, nursing facilities, or private practices to provide nutrition therapy and advise patients about their health and diet. Like dietitians, nutritionists also work to counsel patients about food and health. Some nutritionists have degrees in nutrition or food science, but the title 'nutritionist' is not protected by law. In the United States, anyone is allowed to call themselves a nutritionist, regardless of their education level.

Nutrition counseling can be useful for anyone who is looking to get to a healthy weight, manage a chronic illness through diet, or simply lead a healthier lifestyle. Some examples of issues that benefit from nutrition counseling include:

Obesity
Eating disorders
High cholesterol
High blood pressure
Food allergies
Kidney disease
Digestive disorders, such as irritable bowel syndrome
Cancer
Pregnancy or lactation
Participation in competitive sports

During a nutrition counseling appointment, the provider -- doctor, nutritionist, or dietitian -- typically will look over a the patient's medical history and talk to them about their current diet, their goals, what kinds of food they like, and any problems that they are currently struggling with in their health or diet. Then the specialist will help the patient set food goals and create a customized plan to help them meet their nutritional needs. Nutrition specialists may also offer classes, workshops, cooking demonstrations, and more. Their role is not to lecture the patient about what one should be eating, but to offer education and resources to make eating healthy foods easier.
