Depression is a mood disorder that causes a persistent feeling of sadness and loss of interest. Also called major depressive disorder or clinical depression, it affects how you feel, think and behave and can lead to a variety of emotional and physical problems. You may have trouble doing normal day-to-day activities, and sometimes you may feel as if life isn’t worth living.


Although depression may occur only once during your life, people typically have multiple episodes. During these episodes, symptoms occur most of the day, nearly every day and may include:

  • Feelings of sadness, tearfulness, emptiness or hopelessness
  • Angry outbursts, irritability or frustration, even over small matters
  • Loss of interest or pleasure in most or all normal activities, such as sex, hobbies or sports
  • Sleep disturbances, including insomnia or sleeping too much
  • Tiredness and lack of energy, so even small tasks take extra effort
  • Reduced appetite and weight loss or increased cravings for food and weight gain
  • Anxiety, agitation or restlessness
  • Slowed thinking, speaking or body movements
  • Feelings of worthlessness or guilt, fixating on past failures or self-blame
  • Trouble thinking, concentrating, making decisions and remembering things
  • Frequent or recurrent thoughts of death, suicidal thoughts, suicide attempts or suicide
  • Unexplained physical problems, such as back pain or headaches

Generalized Anxiety

It’s normal to feel anxious from time to time, especially if your life is stressful. However, excessive, ongoing anxiety and worry that are difficult to control and interfere with day-to-day activities may be a sign of generalized anxiety disorder.

It’s possible to develop generalized anxiety disorder as a child or an adult. Generalized anxiety disorder has symptoms that are similar to panic disorder, obsessive-compulsive disorder and other types of anxiety, but they’re all different conditions.


Generalized anxiety disorder symptoms can vary. They may include:

  • Persistent worrying or anxiety about a number of areas that are out of proportion to the impact of the events
  • Overthinking plans and solutions to all possible worst-case outcomes
  • Perceiving situations and events as threatening, even when they aren’t
  • Difficulty handling uncertainty
  • Indecisiveness and fear of making the wrong decision
  • Inability to set aside or let go of a worry
  • Inability to relax, feeling restless, and feeling keyed up or on edge
  • Difficulty concentrating, or the feeling that your mind “goes blank”

Social Anxiety

Social anxiety disorder, also called social phobia, everyday interactions cause significant anxiety, self-consciousness and embarrassment because you fear being scrutinized or judged negatively by others.

In social anxiety disorder, fear and anxiety lead to avoidance that can disrupt your life. Severe stress can affect your relationships, daily routines, work, school or other activities.

Social anxiety disorder can be a chronic mental health condition, but learning coping skills in psychotherapy and taking medications can help you gain confidence and improve your ability to interact with others.


  • Fear of situations in which you may be judged negatively
  • Worry about embarrassing or humiliating yourself
  • Intense fear of interacting or talking with strangers
  • Fear that others will notice that you look anxious
  • Fear of physical symptoms that may cause you embarrassment, such as blushing, sweating, trembling or having a shaky voice
  • Avoidance of doing things or speaking to people out of fear of embarrassment
  • Avoidance of situations where you might be the center of attention
  • Anxiety in anticipation of a feared activity or event
  • Intense fear or anxiety during social situations
  • Analysis of your performance and identification of flaws in your interactions after a social situation
  • Expectation of the worst possible consequences from a negative experience during a social situation

Schizophrenia is a mental disorder in which people interpret reality abnormally. Schizophrenia may result in some combination of hallucinations, delusions, and extremely disordered thinking and behavior which can impair daily functioning. Symptoms can be disabling and distressing.


Schizophrenia involves a range of problems with thinking (cognition), behavior and emotions. Signs and symptoms may vary, but usually involve delusions, hallucinations or disorganized speech, and reflect an impaired ability to function. Symptoms may include:

  • Delusions. These are false beliefs that are not based in reality.
  • Hallucinations. These usually involve seeing or hearing things that don’t exist.
  • Disorganized thinking (speech). Disorganized thinking is inferred from disorganized speech.
  • Extremely disorganized or abnormal motor behavior. This may show in a number of ways, from childlike silliness to unpredictable agitation. Behavior isn’t focused on a goal, so it’s hard to do tasks. Behavior can include resistance to instructions, inappropriate or bizarre posture, a complete lack of response, or useless and excessive movement.
  • Negative symptoms. This refers to reduced or lack of ability to function normally.

A clinical trial may be an option for people experiencing the symptoms above.


Obsessive-compulsive disorder

Obsessive-compulsive disorder (OCD) features a pattern of unwanted thoughts and fears (obsessions) that lead you to do repetitive behaviors (compulsions). These obsessions and compulsions interfere with daily activities and cause significant distress.


Obsessions often have themes to them, such as:

  • Fear of contamination or dirt
  • Doubting and having difficulty tolerating uncertainty
  • Needing things orderly and symmetrical
  • Aggressive or horrific thoughts about losing control and harming yourself or others
  • Unwanted thoughts, including aggression, or sexual or religious subjects

Adolescent Migraines

A migraine is a type of headache that recurs (keeps coming back), and also causes other symptoms. The pain is often throbbing and can happen on one or both sides of the head. People with migraines can feel dizzy or sick to their stomachs. They may be sensitive to light, noise, or smells.

Migraines can be disabling, and teens with migraines often need to skip school, sports, work, or other activities until they feel better.


  • have blurred vision
  • see spots, colored balls, jagged lines, or bright flashing lights
  • smell a certain odor
  • feel tingling in a part of their face
  • unbearable headaches

More About Clinical Research Studies

Clinical research studies and trials create a new opportunity for patients to receive alternative or more varied treatment, and to get up close and personal treatment from healthcare professionals. Often, Clinical research studies provide financially viable treatment options that may not have otherwise been available. By participating in a clinical research study, you would be aiding healthcare officials in their efforts to advance medical knowledge and to find new and better treatment options for patients.

New Treatments For Longer and Better-Quality Lives

The primary goal of all clinical research studies is to determine that the new treatment is both effective and safe for patients. A clinical trial may seek a cure or new methods to ease the lives of patients with chronic illnesses. Participating in a clinical research study allows you to receive the most cutting-edge treatment or procedures in the medical field, and to assist in helping other patients live longer and better-quality lives.

Patient Safety

To ensure the safety of patients during clinical research studies, Excell follows guidelines set by organizations such as the U.S. Food & Drug Administration and the Global International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use Good Clinical Practices (ICH GCP).
