Some issues Dr. Mark Fletcher Simonds, MD can help you with:

Attention Deficit Hyperactivity Disorder (ADHD)

Attention deficit hyperactivity disorder, or ADHD, is one of the most common disorders diagnosed in children. It is characterized by hyperactivity and difficulty maintaining focus or paying attention. ADHD may last into adulthood for some patients. Boys are more likely to be diagnosed with this condition than girls, although medical experts are unsure why this is. ADHD symptoms include:

Forgetfulness in home, school, and work activities
Inability to sustain focus for longer periods of time
Frequent distraction by other stimuli
Tendency to fidget and squirm
Excessive talk and movements

There are three main types of ADHD:

Predominantly hyperactive-impulsive types show symptoms such as constant fidgeting, talking non-stop, touching everything, having trouble sitting still and waiting their turn, and interrupting others.
Predominantly inattentive types are easily distracted or bored. They may wander off during tasks, forget instructions, daydream, or appear not to be listening. This type sometimes goes undiagnosed as children with it are not hyperactive and may have few behavioral issues.
Combined types show symptoms from both categories. This type is the most common type of ADHD.

Treatment can include stimulant medications and behavioral therapy to teach patients ways to navigate their world and control symptoms better. In addition to treatment, accommodations at school or work can greatly help people with ADHD improve their productivity and confidence. A structured environment (with lots of organization and well-defined rules) seems to help most children with ADHD function at their best.

ADHD is mainly thought of as a disorder that affects children, but symptoms can last into adulthood for many. In adults, ADHD has similar symptoms as when it is seen in children: impulsive behavior and difficulty maintaining focus. These symptoms can cause problems in both careers and relationships. Additionally, adults with ADHD are at increased risk for substance abuse. Medications can be an important part of treatment for adults, as well as learning stress reduction techniques and organization skills. Specialized ADHD coaches can help adults with ADHD manage their symptoms and thrive in life.

Bipolar Disorder

Commonly known as manic-depressive illness, bipolar disorder is a serious mental condition characterized by extreme changes in mood. Individuals with this disorder experience emotional highs, or manic episodes, and lows, or depressive episodes. These episodes are distinct periods that are separate from the moods they may usually feel.

During manic episodes, individuals may:

Feel very happy and energetic
Speak very fast and about many different topics
Become much more active than usual
Have trouble sleeping
Engage in impulsive behavior, like spending a large sum of money

In contrast, depressive episodes may bring about:

Sadness, emptiness, or hopelessness
Very low energy and activity levels
Forgetfulness and trouble concentrating
Loss of appetite
Thoughts of death or suicide

Episodes may be a mixture of both manic and depressive symptoms. In such an episode, individuals with bipolar disorder may feel sad, empty, and hopeless but have a high level of energy at the same time. Sometimes, changes in mood are less dramatic. For example, individuals may feel happy and think everything is fine, but people around them may notice their mood changes. Episodes like this are called hypomania. If an individual is hypomanic and does not receive proper treatment, their condition will likely worsen.

Generally considered a lifetime illness, the disorder begins in the late teen or early adult years. Bipolar disorder has no known cause, but research has shown that it tends to run in families. To diagnose it, a psychiatrist carefully assesses an individual's moods and behavior patterns. They may also be asked to keep a daily record of their moods and other factors that can help with diagnosis and determining the right course of therapy. Counseling is a typical form of treatment, as is a group of medications that can control symptoms, called antipsychotics.

Post-Traumatic Stress Disorder (PTSD)

Post-traumatic stress disorder (PTSD) is a mental health disorder that people may develop after experiencing or witnessing a traumatic event. PTSD causes recurring nightmares, flashbacks, and disturbing memories about the traumatic event. It is frequently triggered by particularly intense and life-threatening incidents. For example, someone involved in a serious car accident may have severe anxiety about the accident months or even years later. War veterans and people involved in armed conflict are particularly prone to developing PTSD. In decades past, PTSD was called shellshock and was used to describe the negative emotions that soldiers endured from war. Today, medical professionals who treat PTSD recognize that it can occur in all types of people and can result from all types of traumatic incidents. It is not known exactly why some people develop PTSD, although PTSD frequently arises from:

Accidents
Sexual or physical assault
Combat
Childhood abuse
Domestic abuse
Natural disasters
Torture and kidnapping

People who have experienced significant and repeated trauma are more likely to develop PTSD. Those who have disorders like depression or a family history of depression may also be more prone to PTSD. PTSD symptoms typically begin one month to one year following the traumatic event. There are four main categories of PTSD symptoms:

Intrusive memories: Intrusive memories include unwanted memories, feelings of reliving the traumatic event, distressing nightmares, and emotional disturbances from triggers (signs that serve as reminders of the traumatic event). Intrusive memories can lead to elevated heart rate, anxiety, combativeness (fight), withdrawal (flight), and many other responses.
Avoidance: Avoidance is an attempt to avoid speaking or thinking about an upsetting event. People with this response might also try to avoid certain people or locations that prompt memories of an event.
Changes in physical and emotional reactions: These changes may include difficulty sleeping, hypervigilance, self-destructive behavior, and feelings of guilt and irritability.
Alterations in cognition and mood: Alterations can cause negative self-beliefs, depression, shame, and detachment from others.

The intensity and frequency of these symptoms can vary over time. PTSD symptoms may suddenly return after disappearing for years. Many PTSD patients find treatment helps to gradually reduce their symptoms over time.

The most common treatments for PTSD are psychotherapy and oral medications. Psychotherapy for PTSD can include cognitive therapy (therapy to change thought patterns), exposure therapy (therapy to confront memories of the traumatic incident) and eye movement desensitization and reprocessing therapy (EMDR). EMDR integrates exposure therapy with guided eye movements to help patients confront and process their trauma. Certain oral medications may help with PTSD, such as antidepressants and anti-anxiety medications. Self-care, support groups, and relaxation may also benefit those with PTSD.

The path to overcoming PTSD can be long and challenging and people with PTSD can benefit greatly by seeking professional treatment from a mental health care provider. Treatment can reduce PTSD symptoms, provide essential coping strategies, and improve one's quality of life.

Dr. Simonds is great and easy to talk to. Staff are also great. Virtual visits are easy and the My. Chart app is very helpful. Dr. Simonds has many patients so might not be accepting new patients. Because of his high load, can be difficult to schedule urgent appointments.
