There is no therapy that guarantees to be effective every time for everyone. EMDR is not a cure-all therapy. Certain research indicates that it may be useful in the treatment of trauma and some psychological disorders, whereas others put doubt on this. It is at least as successful as any other alternative treatment modality. In other words, EMDR therapy is simply another tool in a mental health professional's toolbox. Therapists employ EMDR treatment to address a variety of issues: Panic attacks, stress and phobias, chronic Illnesses, Bipolar disorder and unipolar depression, disorders of dissociation and withdrawal, eating disorders, bereavement and loss, performance anxiety, challenges of personality, Post-traumatic stress disorder (PTSD) and other trauma- and stress-related conditions, mental rehabilitation of victims of sexual assault, sleep disorders, addiction, substance abuse and dependence on therapeutic drugs.
