Anxiety

People with generalized anxiety disorder display excessive anxiety or worry, most days for at least 6 months, about a number of things such as personal health, work, social interactions, and everyday routine life circumstances. The fear and anxiety can cause significant problems in areas of their life, such as social interactions, school, and work.

Generalized Anxiety Disorder symptoms include:

• Feeling restless, wound-up, or on-edge
• Being easily fatigued
• Having difficulty concentrating; mind going blank
• Being irritable
• Having muscle tension
• Difficulty controlling feelings of worry
• Having sleep problems, such as difficulty falling or staying asleep, restlessness, or unsatisfying sleep

PTSD

While most but not all traumatized people experience short term symptoms, the majority do not develop ongoing (chronic) PTSD. Not everyone with PTSD has been through a dangerous event. Some experiences, like the sudden, unexpected death of a loved one, can also cause PTSD. Symptoms usually begin early, within 3 months of the traumatic incident, but sometimes they begin years afterward. Symptoms must last more than a month and be severe enough to interfere with relationships or work to be considered PTSD. The course of the illness varies. Some people recover within 6 months, while others have symptoms that last much longer. In some people, the condition becomes chronic.

To be diagnosed with PTSD, an adult must have all of the following for at least 1 month:

• At least one re-experiencing symptom
• At least one avoidance symptom
• At least two arousal and reactivity symptoms
• At least two cognition and mood symptoms

Re-experiencing symptoms include:

• Flashbacks—reliving the trauma over and over, including physical symptoms like a racing heart or sweating
• Bad dreams
• Frightening thoughts

Avoidance symptoms include:

• Staying away from places, events, or objects that are reminders of the traumatic experience
• Avoiding thoughts or feelings related to the traumatic event

Things that remind a person of the traumatic event can trigger avoidance symptoms. These symptoms may cause a person to change his or her personal routine. For example, after a bad car accident, a person who usually drives may avoid driving or riding in a car.

Arousal and reactivity symptoms include:

• Being easily startled
• Feeling tense or “on edge”
• Having difficulty sleeping
• Having angry outbursts

Cognition and mood symptoms include:

• Trouble remembering key features of the traumatic event
• Negative thoughts about oneself or the world
• Distorted feelings like guilt or blame
• Loss of interest in enjoyable activities

ADHD

Inattention and hyperactivity/impulsivity are the key behaviors of ADHD. Some people with ADHD only have problems with one of the behaviors, while others have both inattention and hyperactivity-impulsivity. Most children have the combined type of ADHD.

People with symptoms of inattention may often:

• Overlook or miss details, make careless mistakes in schoolwork, at work, or during other activities
• Have problems sustaining attention in tasks or play, including conversations, lectures, or lengthy reading
• Not seem to listen when spoken to directly
• Not follow through on instructions and fail to finish schoolwork, chores, or duties in the workplace or start tasks but quickly lose focus and get easily sidetracked
• Have problems organizing tasks and activities, such as what to do in sequence, keeping materials and belongings in order, having messy work and poor time management, and failing to meet deadlines
• Avoid or dislike tasks that require sustained mental effort, such as schoolwork or homework, or for teens and older adults, preparing reports, completing forms, or reviewing lengthy papers
• Lose things necessary for tasks or activities, such as school supplies, pencils, books, tools, wallets, keys, paperwork, eyeglasses, and cell phones
• Be easily distracted by unrelated thoughts or stimuli
• Be forgetful in daily activities, such as chores, errands, returning calls, and keeping appointments

People with symptoms of hyperactivity-impulsivity may often:

• Fidget and squirm in their seats
• Leave their seats in situations when staying seated is expected, such as in the classroom or the office
• Run or dash around or climb in situations where it is inappropriate or, in teens and adults, often feel restless
• Be unable to play or engage in hobbies quietly
• Be constantly in motion or “on the go,” or act as if “driven by a motor”
• Talk nonstop
• Blurt out an answer before a question has been completed, finish other people’s sentences, or speak without waiting for a turn in a conversation
• Have trouble waiting for his or her turn
• Interrupt or intrude on others, for example in conversations, games, or activities

Bipolar Disorder

People with bipolar disorder experience periods of unusually intense emotion, changes in sleep patterns and activity levels, and uncharacteristic behaviors—often without recognizing their likely harmful or undesirable effects. These distinct periods are called “mood episodes.” Mood episodes are very different from the moods and behaviors that are typical for the person. During an episode, the symptoms last every day for most of the day. Episodes may also last for longer periods, such as several days or weeks.

OCD

People with OCD may have symptoms of obsessions, compulsions, or both. These symptoms can interfere with all aspects of life, such as work, school, and personal relationships.

Obsessions are repeated thoughts, urges, or mental images that cause anxiety. Common symptoms include:

• Fear of germs or contamination
• Unwanted forbidden or taboo thoughts involving sex, religion, or harm
• Aggressive thoughts towards others or self

Compulsions are repetitive behaviors that a person with OCD feels the urge to do in response to an obsessive thought. Common compulsions include:

• Excessive cleaning and/or handwashing
• Ordering and arranging things in a particular, precise way
• Repeatedly checking on things, such as repeatedly checking to see if the door is locked or that the oven is off
• Compulsive counting

A person with OCD generally:

• Can't control his or her thoughts or behaviors, even when those thoughts or behaviors are recognized as excessive
• Spends at least 1 hour a day on these thoughts or behaviors
• Doesn’t get pleasure when performing the behaviors or rituals, but may feel brief relief from the anxiety the thoughts cause
• Experiences significant problems in their daily life due to these thoughts or behaviors
