Psychogenic diseases, formerly known as ‘hysterical’ illnesses, can have many severe symptoms such as painful cramps or paralysis but without any physical explanation. However, new research from the University of Cambridge and UCL (University College London) suggests that individuals with psychogenic disease, that is to say physical illness that stems from emotional or mental stresses, do have brains that function differently. The research has been published in the journal Brain.
Psychogenic diseases may look very similar to illnesses caused by damage to nerves, the brain or the muscles, or similar to genetic diseases of the nervous system. However, unlike organic diseases, psychogenic diseases do not have any apparent physical cause, making them difficult to diagnose and even more difficult to treat.
“The processes leading to these disorders are poorly understood, complex and highly variable. As a result, treatments are also complex, often lengthy and in many cases there is poor recovery. In order to improve treatment of these disorders, it is important to first understand the underlying mechanism,” said Dr James Rowe from the University of Cambridge.
