A person will typically have these conversations with their doctor and ultimately record their preferences in an advance healthcare directive. An advance healthcare directive is a legal document that either documents a persons decisions about desired treatment or indicates who a person has entrusted to make their care decisions for them. The two main types of advanced directives are a living will and durable power of attorney for healthcare. A living will includes a persons decisions regarding their future care, a majority of which address resuscitation and life support but may also delve into a patients’ preferences regarding hospitalization, pain control, and specific treatments that they may undergo in the future. The living will will typically take effect when a patient is terminally ill with low chances of recovery. A durable power of attorney for healthcare allows a person to appoint another individual to make healthcare decisions for them under a specified set of circumstances. Combined directives, such as the "Five Wishes", that include components of both the living will and durable power of attorney for healthcare, are being increasingly utilized. Advanced care planning often includes preferences for CPR initiation, nutrition (tube feeding), as well as decisions about the use of machines to keep a person breathing, or support their heart or kidneys. Many studies have reported benefits to patients who complete advanced care planning, specifically noting the improved patient and surrogate satisfaction with communication and decreased clinician distress.
Though patients with damage to the OFC retain intact knowledge of social norms, they fail to apply it to actual behaviour because they fail to generate social emotions that promote adaptive social behaviour.The other test, the Iowa gambling task, is a psychological test intended to simulate real-life decision making. The underlying concept of this test is the somatic marker hypothesis. This hypothesis argues that when people have to make complex uncertain decisions, they employ both cognitive and emotional processes to assess the values of the choices available to them. Each time a person makes a decision, both physiological signals and evoked emotion (somatic marker) are associated with their outcomes and it accumulates as experience. People tend to choose the choice which might produce the outcome reinforced with positive stimuli, thus it biases decision-making towards certain behaviours while avoiding others. It is thought that somatic marker is processed in orbitofrontal cortex.The symptoms observed in bvFTD are caused by dysfunction of the orbitofrontal cortex,  thus these two neuropsychological tests might be useful in detecting the early stage bvFTD. However, as self-monitoring and somatic marker processes are so complex, it likely involves other brain regions. Therefore, neuropsychological tests are sensitive to the dysfunction of orbitofrontal cortex, yet not specific to it.
