Every psychotherapist knows that clients' medical problems may lead to anxiety, depression, and other forms of emotional distress. But what even seasoned practitioners may not know is that some physical ailments can directly cause psychological symptoms, at times even before an individual feels ill. This practical book shows that inexplicable, intractable, or sudden mental health problems (as well as perplexing somatic complaints) may be masking serious medical disorders, and aims to help clinicians recognize when a medical referral is advisable. Part one provides an overview of clinical observations that are likely to convey medical information. Part two presents vital information about 60 physical disorders - from leading causes of death such as heart disease, cancer, and stroke, to less prevalent conditions including head trauma, epilepsy and multiple sclerosis. In part three, an easy-to-read chart cross-tabulates each disorder with its specific symptoms. The volume concludes with an annotated list of important references in medicine, neurology and mental health, as well as Internet resources on specific medical problems. This volume is aimed at anyone involved in mental health care, including practitioners and students of psychology, psychiatry, social work, counselling and other mental health fields.
