Some issues Dr. John Lloyd Barrett, MD can help you with:

Headache

Headaches are dull or sharp pains that occur in regions of the head and face. Headaches occur in many different forms and vary in location, severity, and duration. They are not necessarily a sign of an underlying illness and often resolve on their own. However, headaches can present significant day-to-day discomfort. The most common forms of headaches include:

  • Migraines: one of the most prevalent types of headache, migraines typically last from two hours to three days, causing a throbbing pain on one side of the head. Nausea, sensitivity to bright lights, fatigue, and blurred vision all may accompany migraines. While migraines have no known cure, medications and lifestyle modifications may ease symptoms. Avoiding behaviors that may trigger migraines such as lack of sleep or loud, repetitive noises can improve headaches.
  • Tension headaches: also known as stress headaches, these headaches are characterized by pain in the upper top part of the head and behind the eyes. Tension headaches are common and have no exact cause; however, certain practices may increase the likelihood of developing them. For example, wearing one's hair up in a tight hairstyle or wearing a restrictive hat can put pressure on the scalp, leading to a tension headache. Other causes of tension headaches may include alcohol or nicotine use, caffeine, teeth grinding, stress, overexertion, and eye strain. Some people find posture improvement, alternating sleeping positions, and neck exercise can alleviate tension headaches. Over-the-counter pain relievers such as ibuprofen (Advil, Motren) and naproxen sodium (Aleve) may also reduce tension-headache pain.
  • Sinus headaches: this type of headache causes pain in the sinuses, but may progress to pain and pressure in the eyes, forehead, and cheeks. These headaches are often accompanied by nasal congestion, fatigue, and ache in the upper teeth and may or may not be caused by sinus infections or sinusitis (sinus inflammation). Some sinus headaches are allergic headaches, which arise from allergic triggers such as seasonal allergies (pollen allergies) or hay fever, causing sinus pressure and facial pain. Other symptoms of allergic headaches include nasal congestion, irritated or watery eyes, runny nose, and sneezing. Allergic headaches may be treated with antihistamine medications such as cetirizine (Zyrtec). Allergic headaches are common during pollen season, which is usually around springtime.
  • Cluster headaches: these headaches occur suddenly and cause stabbing, sharp pain from one eye down to the one side of the neck. They are often referred to as the most aggravating and painful type of headaches. Other symptoms of cluster headaches include nasal congestion, droopy eyelid, and enlarged pupil on one side of the face. In the past, it was widely believed that cluster headaches were caused by a bevy or "cluster" of multiple types of headaches, such as a combination of an allergic headache and a tension headache. Medical experts now recognize that cluster headaches are a separate and unique form of headache. Cluster headaches last for around twenty minutes to two hours. They may recur throughout the period of a day or several weeks, but usually dissipate within a month. Treatment for cluster headaches includes over-the-counter pain medications such as ibuprofen (Advil, Motren) and naproxen sodium (Aleve). Prescription Prednisone can help with swelling and Verapamil may reduce pain by relaxing the blood vessels.

Living with headaches is challenging; headaches can prevent people from fully enjoying life. Medical treatment and care in avoiding certain triggers can help those with headaches begin to feel normal once again.

Heart Problems

The heart is one of the most important organs in the body. This smooth muscle expands and contracts rhythmically an entire lifetime, pumping blood to the lungs and then to every other cell in the body. When heart problems occur, it becomes difficult for the body to get the nutrients and oxygen it needs via the blood. So while there are a variety of illnesses and disorders that affect the heart, most of them cause weakness, exhaustion and shortness of breath. The most common heart conditions include heart disease, angina, arrhythmia, and valve disorders.

Heart disease is the leading cause of death in the United States for both men and women. This includes coronary artery disease, heart attacks, congestive heart failure, and congenital heart disease. Some conditions, such as genetics, cannot be controlled. But there are many other things one can do to lower their risk for heart disease. Controlling high blood pressure and cholesterol levels, reducing or stopping smoking, exercising more and losing weight if needed, and eating a diet low in sodium can all protect the heart.

Angina is a squeezing type of chest pain that happens when the muscles around the heart don't get enough oxygen. It can be regular or infrequent. Usually, angina is caused by coronary heart disease. However, not all chest pain is angina. Chest pain can also be caused by a lung infection or panic attack, for example, so it is important to have any sudden pain checked.

Arrhythmia is the word for when the heart beats too fast, too slow, or irregularly with skipped beats. It can feel frightening, and depending on the type it can be dangerous, but in most cases arrhythmia is not serious and can be treated. It is very common, especially in older adults.

Heart valve problems can happen in any one of the the heart's four valves that keep blood flowing where it needs to go. Babies can be born with problems in their heart valves, or valves can be damaged by infections. The valves can stiffen and become less mobile, or they can stop closing properly and 'leak' when the heart beats. Valve problems can usually be repaired surgically.

Mental Health Issues

Mental health issues, also referred to as mental health disorders or mental health illnesses, are a wide variety of conditions that impact behavior, emotion, and cognition. There are many different forms of mental health issues, some of which are acute (short-term), while others are chronic. Common mental health issues include:

  • Anxiety disorders, such as obsessive compulsive disorder (OCD), panic disorder, and phobias
  • Mood disorders, such as depression and bipolar disorder
  • Eating disorders, such as anorexia and bulimia
  • Personality disorders, such as borderline and narcissistic personality disorders
  • Grief and trauma, such as post-traumatic stress disorder (PTSD)
  • Impulse control and addiction disorders
  • Psychotic disorders, such as schizophrenia and schizoaffective disorder

No single cause of mental health issues exists. Multiple factors may increase one's risk for developing mental health issues, including but not limited to:

  • Genetic history
  • Chemical imbalances in the brain
  • Traumatic brain injury (TBI)
  • Substance use
  • Exposure to viruses, chemicals, or other substances in the womb
  • Adverse life experiences, such as childhood trauma or recurring stress
  • Isolation and poor living conditions

Mental health issues are typically diagnosed by a provider like a psychiatrist or a psychologist. These issues are diagnosed through psychological evaluation and talk therapy.

Mental health therapy can be an effective tool in supporting people who are struggling with unwanted feelings, behaviors, or difficult circumstances in their lives. Many forms of therapy are available, including specialized therapies tailored to particular disorders. For many issues, therapists help patients manage their conditions through talk therapy. Other treatments can include medication or stays at a psychiatric facility. Mental health therapy can help people with mental health issues improve their mental and emotional wellbeing.
