title: [A patient with feigned mental incompetence requiring medical treatment].
abstract: A woman at the presumed age of 60 years was suspected of malingering cognitive impairment, due to her social circumstances (illegal residency) and was consequently unable to give permission for treatment. She was suffering from locally advanced mammary carcinoma, diagnosed according to the Breast Imaging Reporting and Data System in stage 5. In order to assess mental incompetence, an algorithm from the Royal Dutch Medical Association (KNMG) is a useful tool. The algorithm contains questions for determining whether a patient is able to make choices, if he/she understands medical information and can apply this to his/her own situation and whether he/she is able to logically consider the choice. Mental incompetence is a legally defined status - there is no straightforward relation between mental incompetence and the underlying diagnosis, in this case malingering. Since feigning mental incompetence has its own limitations, the subjective judgment of the physician is important. In the case presented, medical treatment i.e. chemotherapy was started in accordance with the Dutch Medical Treatment Contracts Act (WGBO) for a patient with cognitive impairment. Compulsory treatment was not necessary because the patient did not resist either physically or verbally. If a critical situation is to be prevented or is threatening, then there is no difference between genuine or feigned mental incompetence.
