Explore This Research Lab
The psychiatrists and psychologists on staff in the Center for Anxiety and Traumatic Stress Disorders (CATSD) and Complicated Grief Program at Massachusetts General Hospital explore the causes and treatments for a variety of anxiety-related disorders and seek to also learn more about the underlying causes and course of these disorders.
The research studies conducted by the CATSD provide the opportunity for staff and patients to work together on identifying and developing new treatment methods for these anxiety-related disorders.
We work on a variety of anxiety disorders through our treatment and research program, including:
- Complicated grief
- Generalized anxiety disorder (GAD)
- Panic disorder
- Post-traumatic stress disorder (PTSD)
- Social anxiety
Complicated grief (CG) has also been called "traumatic grief" or "pathological grief" at times. CG grief usually occurs after the death of a loved one. Individuals with CG may find that they are unable to accept the death and that their feelings remain strong and persistent. In addition, there may be certain types of disturbing ideas that seem to inhibit the natural process of gradual diminishing grief intensity. Another way of saying this is that grief isn't working, and the bereaved person is ""stuck"" in the grieving process. When this happens, grief intensity remains high and adjustment does not occur.
Complicated grief is characterized by a number of symptoms that continue for six months or more after a loss:
- Marked depression
- Preoccupation with the deceased
- Disbelief or longing
- Withdrawal or avoidance
These symptoms can cause substantial distress and have been associated with impaired quality of life, poor medical outcomes and increased rates of suicide.
Standard treatments include medications aimed at specific symptoms such as antidepressants, anti-anxiety medications, and sleep-aids. Recent studies suggest that antidepressants such as bupropion (Wellbutrin) and paroxetine (Paxil) may help relieve symptoms of CG.
Use this brief questionnaire (PDF) to evaluate the presence of complicated grief symptoms.
People with generalized anxiety disorder (GAD) find it difficult to control their worry. This inability to stop worrying or to relax, even in the absence of major life stresses, is one of the cardinal features of the disorder.
Individuals with GAD also often experience a number of associated symptoms:
- Restlessness or feeling keyed up or on edge
- Being easily fatigued
- Difficulty concentrating
- Muscle tension
- Sleep disturbance
The anxiety and worry is considered a disorder if it is severe enough to cause an individual significant distress or interferes with social or occupational functioning. Adults with GAD often worry excessively about every day, routine life circumstances such as possible job responsibilities, finances, or the health of family members. A number of effective treatments are available for GAD, such as anti-anxiety medication or cognitive-behavioral therapy (which reduces worry through changes in thinking and behavior patterns).
Panic disorder is characterized by recurrent unexpected panic attacks followed by at least a month of persistent concern about having more attacks, worry about the implications of having an attack (e.g., is there something wrong with my heart?) or a change in behavior related to the attacks (such as avoidance).
Panic attacks are periods of marked fear or anxiety that tend to come on quickly, peak within 10 minutes and are accompanied by distressing symptoms of arousal including:
- Palpitations or heart racing
- Shortness of breath
- Sweating or flushing
- Abdominal distress
- Spaciness or feeling as if you may be going crazy, dying or losing control
Many patients with panic disorder develop agoraphobia, which is a concern about being in places or situations in which help or easy escape may not be available in the event of having an attack, or in which previous attacks have occurred. Some individuals with agoraphobia avoid the situations they are afraid of or require a companion to accompany them, others endure them with a great deal of distress.
Panic disorder can cause significant difficulties, including marked distress, social and job-related dysfunction, increased utilization of medical services (e.g., visits to doctors and emergency rooms) and increased rates of depression and alcohol abuse. A number of effective treatments are available, including medications such as antidepressants or benzodiazepines ("Valium-like" medications) and psychotherapies such as cognitive-behavioral therapy.
Post-traumatic Stress Disorder (PTSD)
Many kinds of traumatic events can lead to the development of PTSD, such as:
- Car accidents
- Natural disasters such as hurricanes or earthquakes
- Physical or sexual assault
- Emotional, physical or sexual abuse
- Combat exposure
- Learning about the unexpected death or injury of a loved one
Although not all individuals exposed to a trauma develop PTSD, some individuals experience a number of distressing psychological and physical symptoms including re-experiencing, avoidance or numbing and hyperarousal.
Re-experiencing symptoms include:
- Recurrent and intrusive thoughts about the event
- Upsetting dreams or nightmares
- Flashbacks to the trauma
- Becoming extremely upset or anxious when reminded of the trauma
Avoidance and numbing symptoms include:
- Avoiding thinking or talking about the trauma
- Avoiding places, situations or people reminiscent of the trauma
- Being unable to recall certain parts of what happened
- Losing interest in previously valued activities
- Feeling distant or detached from others
- Having difficulty experiencing strong emotions
- Feeling a lack of interest or hope in the future (e.g., feeling one will never have a career, get married, live to old age)
Hyperarousal symptoms include:
- Difficulty falling or staying asleep
- Feeling irritable or having outbursts of anger
- Difficulty concentrating
- Feeling hypervigilant even if there is no reason to be
- Being easily startled
In order to receive a PTSD diagnosis, symptoms must persist for at least one month and cause significant distress, interference, or impairment in work, school, or social functioning. Symptoms may last for several months, or become even more chronic. For some, PTSD symptoms emerge six months or more after the traumatic event.
Treatment of PTSD
There are a number of effective medications available to treat the symptoms of PTSD, including antidepressants and some newer anti-anxiety or mood-stabilizing medications. Many individuals with PTSD do well with treatment that includes both psychotherapy and medication.
Cognitive behavioral therapy (CBT), including prolonged exposure, cognitive processing therapy and skills training in affect and interpersonal regulation, is effective for many patients with PTSD. CBT usually involves working closely with a therapist to systematically process the traumatic event, identify and modify negative thoughts that interfere with recovery from the trauma and learn to face situations or feelings associated with the trauma. In addition, CBT helps individuals learn skills for managing difficult emotions and overcoming difficulties in interpersonal relationships.
Social Anxiety Disorder (Social Phobia)
When an individual with social phobia enters or thinks about entering a feared situation, anxiety increases and for some may result in symptoms of a panic attack. Examples of feared situations include persistent fear of public speaking, meeting new people, attending parties, going to school or having social contact through a job.
Although most people have some anxiety about social and/or performance situations, these fears are more severe, persist and may limit participation in or enjoyment of every-day activities for an individual with social phobia. Social anxiety symptoms may interfere with success or completion of school, making new friends, creating relationships and employment.
Nonetheless, many individuals suffer with social phobia for many years without a diagnosis or treatment. However, there are a number of effective treatments available. Options include medications such as antidepressants or benzodiazepines ("Valium-like" medications) and psychotherapy (counseling or "talk therapy"), especially cognitive behavioral therapy.
Our psychiatrists and psychologists draw on years of experience and are focused on treating and conducting extensive research.

Comparative Effectiveness of Mindfulness-Based Stress Reduction and Pharmacotherapy for Anxiety
Description: The purpose of this study is to compare the effects of mindfulness-based stress reduction (MBSR) with Lexapro (escitalopram) to see how they compare for treating anxiety disorders. MBSR is a class that instructs participants in the theory and practice of several forms of mindfulness meditation. Escitalopram (Lexapro) is an antidepressant medication that is FDA-approved for the treatment of generalized anxiety disorder and depression. It is commonly used in practice for other anxiety disorders.
This research is being done because there is a need for more information about the comparison of treatments to be able to make informed decisions about health care for disorders. Although mindfulness meditation is gaining popularity, there is no information how this treatment strategy compares with standard treatment, such as medication, for anxiety disorders.

- PTSD symptoms experienced for at least three months
Compensation: Participants will be paid $25 upon completion of the intake visit, as well as $25 for each of 7 study assessment visits, for a maximum total of $200.
Complicated Grief Disorder
Network Psychiatry: Using Network Science to Advance Our Understanding of Post-Bereavement Psychopathology
Description: We are is seeking adult participants who experienced the death of a loved one more than six months ago for a study of bereavement. The aim of this study is to learn more about how people adjust to the death of a loved one. Specifically, we hope to investigate the psychological and biological mechanisms that lead grief to persist for some bereaved adults but not others. The study will last approximately 2.5 weeks and will require two in-person visits to our clinic. Additionally, you will be asked to complete daily surveys on your phone. All collected information will remain strictly confidential.
You may be eligible if:
- You are 18 or older
- You own a smartphone (iPhone or Android) and have daily access to a laptop or computer
- You have lost a loved one more than six months ago
Please call our phone screen line at 1-866-44-WORRY (866-449-6779) or email us at firstname.lastname@example.org for a full phone screen to determine if you would be eligible to come into the clinic to meet with one of the study doctors.
Compensation: Eligible participants would receive up to $250 in compensation.
Optimizing cognitive behavioral therapy for panic disorder: Examining mechanisms of treatment change using an intra-individual network of panic attacks
Description: The purpose of this research study is to examine how symptoms of panic disorder change during cognitive behavioral therapy (CBT) for panic disorder. The aim of this type of research is to focus on the symptoms and experiences of each person through the course of treatment, in order to develop a framework for a personalized medicine approach to treating panic disorder. All participants will receive seven sessions of CBT.
- Individuals 18 years of age and older with a primary diagnosis of panic disorder (as determined by the psychiatrists who conduct our initial screening process)
- Participants need to own a smart phone to complete the pre- and post- treatment assessments.
- Participants cannot have agoraphobia that limits their ability to travel to weekly sessions. Participants cannot be at current risk of suicide.
- Psychotropic medication is permitted if the participant is on a stable dose.
- Within the last 3 months, participants cannot have received psychotherapy directed at the treatment of panic disorder. Prior non-response to adequately delivered exposure therapy also disqualifies.
Please call our phone screen line at 866-44-WORRY (866-449-6779) or email us at email@example.com for a full phone screen to determine if you would be eligible to come into the clinic to meet with one of the study doctors.
