While some of these Selective Mutism symptoms may be recognized by family, teachers, legal and medical professionals, and others, only properly trained mental health professionals (psychologists, psychiatrists, professional counselors etc.) can or should even attempt to make a mental health diagnosis. A multitude of factors are considered in addition to the psychological symptoms in making a proper diagnosis, including medical and psychological testing considerations. This information is for information purposes only and should never replace the judgment and comprehensive assessment of a trained mental health clinician.
